Intel Promises 'Optane' SSDs Based On Technology Faster Than Flash In 2016 80

holy_calamity writes: Intel today announced that it will introduce SSDs based on a new non-volatile memory that is significantly faster than flash in 2016. A prototype was shown operating at around seven times as fast as a high-end SSD available today. Intel's new 3D Xpoint memory technology was developed in collaboration with Micron and is said to be capable of operating as much as 1000 times faster than flash. Scant details have been released, but the technology has similarities with the RRAM and memristor technologies being persued by other companies.

Samsung Unveils V-NAND High Performance SSDs, Fast NVMe Card At 5.5GB Per Second 61

MojoKid writes: Sometimes it's the enterprise sector that gets dibs on the coolest technology, and so it goes with a trio of TCO-optimized, high-performance solid state drives from Samsung that were just announced, all three of which are based on three-dimensional (3D) Vertical NAND (V-NAND) flash memory technology. The fastest of bunch can read data at up to 5,500 megabytes per second. That's the rated sequential read speed of Samsung's PM1725, a half-height, half-length (HHHL) PCIe card-type NVMe SSD. Other rated specs include a random read speed of up to 1,000,000 IOPS, random write performance of up to 120,000 IOPS, and sequential writes topping out at 1,800MB/s. The PM1725 comes in just two beastly storage capacities, 3.2TB and 6.4TB, the latter of which is rated to handle five drive writes per day (32TB) for five years. Samsung also introduced two other 3D V-NAND products, the PM1633 and PM953. The PM1633 is a 2.5-inch 12Gb/s SAS SSD that will be offered in 480GB, 960GB, 1.92TB, and 3.84TB capacities. As for the PM953, it's an update to the SM951 and is available in M.2 and 2.5-inch form factors at capacities up to 1.92TB.

Samsung Finds, Fixes Bug In Linux Trim Code 184

New submitter Mokki writes: After many complaints that Samsung SSDs corrupted data when used with Linux, Samsung found out that the bug was in the Linux kernel and submitted a patch to fix it. It turns out that kernels without the final fix can corrupt data if the system is using linux md raid with raid0 or raid10 and issues trim/discard commands (either fstrim or by the filesystem itself). The vendor of the drive did not matter and the previous blacklisting of Samsung drives for broken queued trim support can be most likely lifted after further tests. According to this post the bug has been around for a long time.

OCZ Toshiba Breaks 40 Cent Per GB Barrier With New Trion 100 Series SSD 144

MojoKid writes: OCZ is launching a brand new series of solid state drives today, dubbed the Trion 100. Not only are they the first drives from the company to use TLC NAND, but they're also the first to use all in-house Toshiba technology with the drive's Flash memory and controller both designed and built by Toshiba. That controller is paired to A19nm Toshiba TLC NAND Flash memory and a Nanya DDR3 DRAM cache. Details are scarce on the Toshiba TC58 controller but it does support Toshiba's QSBC (Quadruple Swing-By Correction — a Toshiba proprietary error correction technology) and the drives have a bit of SLC cache to boost write performance in bursts and increase endurance. The OCZ Trion 100 series is targeted at budget conscious consumers and users still contemplating the upgrade from a standard hard drive. As such, they're not barn-burners in the benchmarking department, but performance is still good overall and a huge upgrade over any HDD. Pricing is going to be very competitive as well, at under .40 per GiB for capacities of 240GB, 480GB and 960GB and .50 per GiB for the smallest 120GB drive.

Samsung Releases First 2TB Consumer SSD For Laptops 195

Lucas123 writes: Samsung has released what it is calling the world's first 2.5-in consumer-grade, multi-terabyte SSD, and it's issuing the new drive a 10-year warranty. With up to 2TB of capacity, the new 850 Pro and 850 EVO SSDs double the maximum capacity of their predecessors. As with the previous 840 Pro and EVO models, Samsung used its 3D V-NAND technology, which stacks 32 layers of NAND atop one another in a microscopic skyscraper. Additionally, the drives take advantage of multi-level cell (MLC) and triple-level cell (TLC) (2- and 3-bit per cell) technology for even greater density. The 850 Pro, Samsung said, can manage up to 550MBps sequential read and 520MBps sequential write rates and up to 100,000 random I/Os per second (IOPS). The 850 EVO SSD has slightly lower performance with 540MBps and 520MBps sequential read/write rates and up to 90,000 random IOPS. The SSDs will range in capacity from 120GB to 2TB and in price from $99 to $999.

Ask Slashdot: Are Post-Install Windows Slowdowns Inevitable? 517

blackest_k writes: I recently reinstalled Windows 7 Home on a laptop. A factory restore (minus the shovelware), all the Windows updates, and it was reasonably snappy. Four weeks later it's running like a slug, and now 34 more updates to install. The system is clear of malware (there are very few additional programs other than chrome browser). It appears that Windows slows down Windows! Has anyone benchmarked Windows 7 as installed and then again as updated? Even better has anybody identified any Windows update that put the slug into sluggish? Related: an anonymous reader asks: Our organization's PCs are growing ever slower, with direct hard-drive encryption in place, and with anti-malware scans running ever more frequently. The security team says that SSDs are the only solution, but the org won't approve SSD purchases. It seems most disk scanning could take place after hours and/or under a lower CPU priority, but the security team doesn't care about optimization, summarily blaming sluggishness on lack of SSDs. Are they blowing smoke?

TRIM and Linux: Tread Cautiously, and Keep Backups Handy 182

An anonymous reader writes: Algolia is a buzzword-compliant ("Hosted Search API that delivers instant and relevant results") start-up that uses a lot of open-source software (including various strains of Linux) and a lot of solid-state disk, and as such sometimes runs into problems with each of these. Their blog this week features a fascinating look at troubles that they faced with ext4 filesystems mysteriously flipping to read-only mode: not such a good thing for machines processing a search index, not just dishing it out. "The NGINX daemon serving all the HTTP(S) communication of our API was up and ready to serve the search queries but the indexing process crashed. Since the indexing process is guarded by supervise, crashing in a loop would have been understandable but a complete crash was not. As it turned out the filesystem was in a read-only mode. All right, let's assume it was a cosmic ray :) The filesystem got fixed, files were restored from another healthy server and everything looked fine again. The next day another server ended with filesystem in read-only, two hours after another one and then next hour another one. Something was going on. After restoring the filesystem and the files, it was time for serious analysis since this was not a one time thing.

The rest of the story explains how they isolated the problem and worked around it; it turns out that the culprit was TRIM, or rather TRIM's interaction with certain SSDs: "The system was issuing a TRIM to erase empty blocks, the command got misinterpreted by the drive and the controller erased blocks it was not supposed to. Therefore our files ended-up with 512 bytes of zeroes, files smaller than 512 bytes were completely zeroed. When we were lucky enough, the misbehaving TRIM hit the super-block of the filesystem and caused a corruption."

Since SSDs are becoming the norm outside the data center as well as within, some of the problems that their analysis exposed for one company probably would be good to test for elsewhere. One upshot: "As a result, we informed our server provider about the affected SSDs and they informed the manufacturer. Our new deployments were switched to different SSD drives and we don't recommend anyone to use any SSD that is anyhow mentioned in a bad way by the Linux kernel."

An anonymous reader writes: Here's something we haven't done in a while: list the specs of your main system (best one) so we can see what kinds of computers Slashdot geeks use. Context would be interesting, too — if you're up for it, explain how and why you set it up as you did, as well as the computer's primary purpose(s). Things you can list include (but are not limited to): CPU, motherboard, video card, memory, storage (SSD/HDD), exotic Controllers (RAID or caching), optical drives, displays, peripherals, etc. We can compare and contrast, see what specs are suitable for what purposes, and perhaps learn a trick or two.

NAND Flash Shrinks To 15/16nm Process, Further Driving Prices Down 60

Lucas123 writes: Both Micron and Toshiba are producing NAND flash memory based on 15 and 16 nanometer process technology, which reduces die area over a 16GB MLC chip by 28% compared with previous die technology. Additionally, Micron announced its upcoming consumer USB flash drives and internal SSDs will also use triple-level cell NAND flash (a technology expected to soon dominate the market) storing three bits instead of two for the first time and further reducing production cost. The advancement in NAND flash density has been driving SSD pricing down dramatically over the past few years. In fact, over the last year, the average price for 128GB and 256GB SSDs have dropped to $50 and $90, respectively, for system manufacturers, according to DRAMeXchange. And prices for consumers have dropped to an average of $91.55 for a 128GB SSD and $164.34 for a 256GB SSD.

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

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

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.

Enterprise SSDs, Powered Off, Potentially Lose Data In a Week 184

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

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

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

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

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.

New Samsung SSD 840 EVO Read Performance Fix Coming Later This Month 72

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.
