No, Your SSD Won't Quickly Lose Data While Powered Down 106

from the news-that-harder-to-freak-out-about dept.
An anonymous reader writes: A few weeks ago, we discussed reports that enterprise SSDs would lose data in a surprisingly short amount of time if left powered off. The reports were based on a presentation from Alvin Cox, a Seagate engineer, about enterprise storage practices. PCWorld spoke to him and another engineer for Seagate, and they say the whole thing was blown out of proportion. Alvin Cox said, "I wouldn't worry about (losing data). This all pertains to end of life. As a consumer, an SSD product or even a flash product is never going to get to the point where it's temperature-dependent on retaining the data." The intent of the original presentation was to set expectations for a worst case scenario — a data center writing huge amounts of data to old SSDs and then storing them long-term at unusual temperatures. It's not a very realistic situation for businesses with responsible IT departments, and almost impossible for personal drives.

Dell Precision M3800 Mobile Workstation Packs Thunderbolt 2, Quadro, IGZO2 Panel 133

Posted by samzenpus
from the running-the-numbers dept.
MojoKid writes: Dell recently revamped their M3800 model to better entice graphic designers, engineers, and other high-end users who often work in the field, with a true mobile workstation that's both sufficiently equipped to handle professional grade workloads and is thin and light to boot. Dell claims the M3800 is the "world's thinnest and lightest 15-inch mobile workstation" and at 4.15 pounds, it could very well be. In addition, ISV tools certifications matter for workstation types, so the M3800 gets its pixel pushing muscle from an NVIDIA Quadro K1100M GPU with 2GB of GDDR5 memory. Other notable specs include an Intel Core i7-4712HQ quad-core processor, 16GB of DDR3L memory, and a 256GB mSATA SSD. One of the new additions to the M3800 is a Thunderbolt 2 port with transfer speeds of up to 20Gbps that allows for the simultaneous viewing/editing and backing up of raw 4K video. Finally, the M3800 is equipped with a 3840x2160 native resolution IGZO2 display, which equates to a 60 percent increase in pixel density over a current gen MacBook Pro with Retina display. Performance-wise, the M3800 holds up pretty strong with standard productivity workloads, though as you can image it excels more-so in graphics rendering throughput.

from the other-side-of-solid-state's-speed dept.
New submitter Mal-2 writes with a selection from IB Times of special interest for anyone replacing hard disks with solid state drives: The standards body for the microelectronics industry has found that Solid State Drives (SSD) can start to lose their data and become corrupted if they are left without power for as little as a week. ... According to a recent presentation (PDF) by Seagate's Alvin Cox, who is also chairman of the Joint Electron Device Engineering Council (JEDEC), the period of time that data will be retained on an SSD is halved for every 5 degrees Celsius (9 degrees Fahrenheit) rise in temperature in the area where the SSD is stored. If you have switched to SSD for either personal or business use, do you follow the recommendation here that spinning-disk media be used as backup as well?

Samsung's SSD 840 Read Performance Degradation Explained 65

Posted by timothy
from the failure-to-spin-is-actually-ok-in-this-case dept.
An anonymous reader writes with a link to TechSpot's explanation of the reason behind the performance degradation noticed by many purchasers of certain models of Samsung SSD (the 840 and 840 EVO), and an evaluation of the firmware updates that the firm has released to address is. From the piece, a mixed but positive opinion of the second and latest of these firmware releases: "It’s not an elegant fix, and it’s also a fix that will degrade the lifetime of the NAND since the total numbers of writes it’s meant to withstand is limited. But as we have witnessed in Tech Report’s extensive durability test there is a ton of headroom in how NAND is rated, so in my opinion this is not a problem. Heck, the Samsung 840 even outlasted two MLC drives. As of writing, the new firmware has only been released for the 2.5” model of the SSD 840 EVO, so users of the 840 EVO mSATA model still have to be patient. It should also be noted that the new firmware does not seem to work well with the TRIM implementation in Linux, as this user shared how file system corruption occurs if discard is enabled."

New PCIe SSDs Load Games, Apps As Fast As Old SATA Drives 162

Posted by samzenpus
from the you-don't-need-a-race-car-if-you're-just-driving-to-work dept.
crookedvulture writes Slashdot has covered a bunch of new PCI Express SSDs over the past month, and for good reason. The latest crop offers much higher sequential and random I/O rates than predecessors based on old-school Serial ATA interfaces. They're also compatible with new protocols, like NVM Express, which reduce overhead and improve scaling under demanding loads. As one might expect, these new PCIe drives destroy the competition in targeted benchmarks, hitting top speeds several times faster than even the best SATA SSDs can muster. The thing is, PCIe SSDs don't load games or common application data any faster than current incumbents—or even consumer-grade SSDs from five years ago. That's very different from the initial transition from mechanical to solid-state storage, where load times improved noticeably for just about everything. Servers and workstations can no doubt take advantage of the extra oomph that PCIe SSDs provide, but desktop users may struggle to find scenarios where PCIe SSDs offer palpable performance improvements over even budget-oriented SATA drives.

Kingston HyperX Predator SSD Takes Gumstick M.2 PCIe Drives To 1.4GB/sec 51

Posted by timothy
from the sure-hope-those-drives-appreciated-it dept.
MojoKid writes Kingston recently launched their HyperX Predator PCIe SSD that is targeted at performance-minded PC enthusiasts but is much less expensive than enterprise-class PCIe offerings that are currently in market. Kits are available in a couple of capacities and form factors at 240GB and 480GB. All of the drives adhere to the 80mm M.2 2280 "gumstick" form factor and have PCIe 2.0 x4 connections, but are sold both with and without a half-height, half-length adapter card, if you'd like to drop it into a standard PCI Express slot. At the heart of the Kingston HyperX Predator is Marvell's latest 88SS9293 controller. The Marvell 88SS9293 is paired to a gigabyte of DDR3 memory and Toshiba A19 Toggle NAND. The drives are rated for read speeds up to 1.4GB/s and writes of 1GB/s and 130 – 160K random 4K IOPS. In the benchmarks, the 480GB model put up strong numbers. At roughly $1 per GiB, the HyperX Predator is about on par with Intel's faster SSD 750, but unlike Intel's new NVMe solution, the Kingston drive will work in all legacy platforms as well, not just Z97 and X99 boards with a compatible UEFI BIOS.

Samsung SSD On a Tiny M.2 Stick Is Capable of Read Speeds Over 2GB/sec 72

Posted by Soulskill
from the unless-it's-got-the-evo840-problem dept.
MojoKid writes: Samsung has just announced its new SM951-NVMe SSD, the industry's first NVMe SSD to employ an M.2 form-factor. Samsung says the new gumstick style drive is capable of sequential read and write speeds of 2,260 MB/sec and 1,600 MB/sec respectively. Comparable SATA-based M.2 SSDs typically can only push read/write speeds of 540 MB/sec and 500 MB/sec, while most standard PCIe versions muster just north of 1GB/sec. The Samsung SM951-NVMe's performance is actually very comparable to the Intel SSD 750 Series PCIe x4 card but should help kick notebook performance up a notch in this common platform configuration.

An anonymous reader writes: The Samsung SSD 840 EVO read performance bug has been on the table for over six months now. Initially Samsung acknowledged the issue fairly quickly and provided a fix only a month after the news hit the mainstream tech media, but reports of read performance degradation surfaced again a few weeks after the fix had been released, making it clear that the first fix didn't solve the issue for all users. Two months ago Samsung announced that a new fix is in the works and last week Samsung sent out the new firmware along with Magician 4.6 for testing, which will be available to the public later this month.

Ask Slashdot: Best Medium For Storing Data To Survive a Fire (or Other Disaster) 446

Posted by samzenpus
from the burning-down-the-house dept.
First time accepted submitter aka_bigred writes Every year as I file my taxes, I replicate my most important financial data (a couple GB of data) to store an offline copy in my fire-rated home safe. This gets me thinking about what the most reliable data media would be to keep in my fire-rated home safe.

CDs/DVDs/tapes could easily melt or warp rendering them useless, so I'm very hesitant to use them. I've seen more exotic solutions that let you print your digital data to paper an optically re-import it later should you ever need it, but it seems overly cumbersome and error prone should it be damaged or fire scorched. That leaves my best options being either a classic magnetic platter drive, or some sort of solid state storage, like SD cards, USB flash drives, or a small SSD. The problem is, I can't decide which would survive better if ever exposed to extreme temperatures, or water damage should my house burn down.

Most people would just suggest to store it in "the cloud", but I'm naturally averse to doing so because that means someone else is responsible for my data and I could lose it to hackers, the entity going out of business, etc. Once it leaves my home, I no longer fully control it, which is unacceptable. My thought being "they can't hack/steal what they can't physically access." What medium do other Slashdot users use to store their most important data (under say 5GB worth) in an at-home safe to protect it from fire?

Intel Launches SSD 750 Series Consumer NVMe PCI Express SSD At Under $1 Per GiB 67

Posted by timothy
from the good-kind-of-race-for-the-bottom dept.
MojoKid writes Today, Intel took the wraps off new NVMe PCI Express Solid State Drives, which are the first products with these high speed interfaces, that the company has launched specifically for the enthusiast computing and workstation market. Historically, Intel's PCI Express-based offerings, like the SSD DC P3700 Series, have been targeted for datacenter or enterprise applications, with price tags to match. However, the Intel SSD 750 Series PCI Express SSD, though based on the same custom NVMe controller technology as the company's expensive P3700 drive, will drop in at less than a dollar per GiB, while offering performance almost on par with its enterprise-class sibling. Available in 400GB and 1.2TB capacities, the Intel SSD 750 is able to hit peak read and write bandwidth numbers of 2.4GB/sec and 1.2GB/sec, respectively. In the benchmarks, it takes many of the top PCIe SSD cards to task easily and at $389 for a 400GB model, you won't have to sell an organ to afford one.

Micron and Intel Announce 3D NAND Flash Co-Development To Push SSDs Past 10TB 93

Posted by timothy
from the 10TB-can-hold-quite-a-few-home-movies dept.
MojoKid writes Both Micron and Intel noted in a release today that traditional planar NAND flash memory is reaching a dead-end, and as such, have been working together on 3D memory technology that could open the floodgates for high densities and faster speeds. Not all 3D memory is alike, however. This joint development effort resulted in a "floating gate cell" being used, something not uncommon for standard flash, but a first for 3D. Ultimately, this 3D NAND is composed of flash cells stacked 32 high, resulting in 256Gb MLC and 384Gb TLC die that fit inside of a standard package. That gives us 48GB per die, and up to 750GB in a single package. Other benefits include faster performance, reduced cost, and technologies that help extend the life of the memory.

Posted by samzenpus
from the check-it-out dept.
MojoKid writes Lenovo just revamped the ThinkPad X1 Carbon and in this third generation of the machine, they've adopted Intel's latest 5th generation Core Series Broadwell processors, along with a few other updates. In addition, they've retooled the keyboard and trackpad area, returning back to more traditional roots versus the second generation machine, which was met with some criticism due to its adaptive function key row and over-simplified, buttonless trackpad. Notable upgrades to this 3rd gen model are a faster Core i5-5300U processor and a self-encrypting Opal2 compliant SSD. Performance-wise, the new ThinkPad offers up some of the best numbers in utlrabooks currently, though battery life is a bit middle of the road, but still able to last over 8 hours under light, web-driven workloads.

Endurance Experiment Kills Six SSDs Over 18 Months, 2.4 Petabytes 204

Posted by timothy
from the die-die-die dept.
crookedvulture writes Slashdot has previously covered The Tech Report's SSD Endurance Experiment, and the final chapter in that series has now been published. The site spent the last 18 months writing data to six consumer-grade SSDs to see how much it would take to burn their flash. All the drives absorbed hundreds of terabytes without issue, far exceeding the needs of typical PC users. The first one failed after 700TB, while the last survived an astounding 2.4 petabytes. Performance was reasonably consistent throughout the experiment, but failure behavior wasn't. Four of the six provided warning messages before their eventual deaths, but two expired unexpectedly. A couple also suffered uncorrectable errors that could compromise data integrity. They all ended up in a bricked, lifeless state. While the sample size isn't large enough to draw definitive conclusions about specific makes or models, the results suggest the NAND in modern SSDs has more than enough endurance for consumers. They also demonstrate that very ordinary drives can be capable of writing mind-boggling amounts of data.

Google's Pricey Pixel Gets USB-C and a Lower Price 139

Posted by timothy
from the dang-I-say-dang dept.
The Register reports that Google's high-end Chromebook Pixel has gotten a few spec bumps, and a lower price. It's still a touchscreen with a resolution of 2,560 × 1,700, but now that screen is backed by 8GB RAM (rather than 4) as a base configuration, and the system is equipped with a Broadwell Core i5 chip, rather than the Ivy Bridge in the first rev. The price has dropped, too; it may still be the most expensive Chromebook, but now it's "only" $999 on the low end, which is $300 less than the first Pixels cost. ($1300, though, gets an i7, 64 gigs of SSD instead of 32, and 8GB of RAM. Perhaps most interesting is that it adds USB type C, and (topping Apple's latest entry) it's got two of them.

MojoKid writes Laptops with fully articulating hinges are starting to show up from more vendors than just Lenovo, though the company certainly got some mileage out of their Yoga brand of machines. Now it appears HP is getting in on the action as well, with the new HP Spectre X360 that's powered by Intel's new Core i5-5200U Broadwell-based processor with integrated Intel HD 5500 series graphics, along with 8GB of DDR3-1600 memory, a 256GB Solid State Drive (a Samsung M.2 PCIe SSD), 802.11ac WiFi, and a 13.3" Full HD (1920x1080) multi-touch screen. The Spectre X360 has a geared and spring-assisted hinges. The hinges swing open easily, and then offer more resistance as the screen is moved into an upright position, or swung around into tent, stand, or tablet modes. What's also interesting about this new breed of convertibles, beyond just its ability to contort into tablet mode and various other angles, is that performance for these ultralight platforms is scaling up nicely, with faster, low-power processors and M.2 PCIe Solid State Drives offering up a very responsive experience and under 10 second boot times. It has gotten to the point that 3 pound and under notebooks feel every bit as nimble as desktop machines, at least for mainstream productivity and media consumption usage models.

New Seagate Shingled Hard Drive Teardown 93

Posted by Soulskill
from the made-out-of-actual-shingles dept.
New submitter Peter Desnoyers writes: Shingled Magnetic Recording (SMR) drives are starting to hit the market, promising larger drives without heroic (and expensive) measures such as helium fill, but at a cost — data can no longer be over-written in place, requiring SSD-like algorithms to handle random writes.

At the USENIX File and Storage Technologies conference in February, researchers from Northeastern University (disclaimer — I'm one of them) dissected shingled drive performance both figuratively and literally, using both micro-benchmarks and a window cut in the drive to uncover the secrets of Seagate's first line of publicly-available SMR drives.

TL;DR: It's a pretty good desktop drive — with write cache enabled (the default for non-server setups) and an intermittent workload it performs quite well, handling bursts of random writes (up to a few tens of GB total) far faster than a conventional drive — but only if it has long powered-on idle periods for garbage collection. Reads and large writes run at about the same speed as on a conventional drive, and at $280 it costs less than a pair of decent 4TB drives. For heavily-loaded server applications, though, you might want to wait for the next generation. Here are a couple videos (in 16x slow motion) showing the drive in action — sequential read after deliberately fragmenting the drive, and a few thousand random writes.

MojoKid writes Intel recently released its latest generation of NUC small form factor systems, based on the company's new low-power Broadwell-U series processors. The primary advantages of Intel's 5th Generation Core Series Broadwell-U-based processors are better performance-per-watt, stronger integrated graphics, and a smaller footprint, all things that are perfectly suited to the company's NUC (Next Unit of Computing) products. The Intel NUC5i5RYK packs a Core i5-5250U processor with on-die Intel HD 6000 series graphics. The system also sports built-in 802.11ac Wi-Fi, Gigabit Ethernet, USB 3.0 and USB 2.0, M.2 SSD support, and a host of other features, all in a 115mm x 111mm x 32.7mm enclosure. Performance-wise the new 5th Gen Core Series-powered NUC benchmarks like a midrange notebook and is actually up for a bit of light-duty gaming, though it's probably more at home as a Home Theater PC, media streamer or kiosk desktop machine.

MojoKid (1002251) writes Asus announced their super-slim Zenbook UX305 during the IFA trade show in Berlin in September. The machine will be available in two models, one with a 1920x1080 IPS display and one with a QHD+ display that boasts a native resolution of 3200x1800. They're both built around Intel's more power-efficient Core M processor, which was designed for ultra-thin and "fanless" form factors. Intel's Core M does seem to offer significant advances both in terms of power consumption and performance, which enables many of the design features found on the 12.3mm thin UX305. The Core M 5Y10 in the Asus Zenbook UX305 is complemented by 8GB of RAM, a 256GB SSD, and this is one of the few ultrabooks to feature a matte display. All told, the machine put up some decent numbers in the benchmarks and battery life was excellent, but what's perhaps most interesting is that this is an "ultrabook" class machine that weighs in at a much more palatable $700 price tag.

Samsung's Portable SSD T1 Tested 105

Posted by samzenpus
from the where-the-rubber-hits-the-road dept.
MojoKid writes The bulk of today's high-capacity external storage devices still rely on mechanical hard disk drives with spinning media and other delicate parts. Solid state drives are much faster and less susceptible to damage from vibration, of course. That being the case, Samsung saw an opportunity to capitalize on a market segment that hasn't seen enough development it seems--external SSDs. There are already external storage devices that use full-sized SSDs, but Samsung's new Portable SSD T1 is more akin to a thumb drive, only a little wider and typically much faster. Utilizing Samsung's 3D Vertical NAND (V-NAND) technology and a SuperSpeed USB 3.0 interface, the Portable SSD T1 redlines at up to 450MB/s when reading or writing data sequentially, claims Samsung. For random read and write activities, Samsung rates the drive at up to 8,000 IOPS and 21,000 IOPS, respectively. Pricing is more in-line with high-performance standalone SSDs, with this 1TB model reviewed here arriving at about $579. In testing, the drive did live up to its performance and bandwidth claims as well.
