...is that in a properly-designed SSD, there is no such thing as data fragmentation. You lay out the nand as a circular log and write to every bit of it once before you overwrite, and maintain a set of pointers that translates LBA to memory addresses.

Pretty much every SSD vendor out there has figured this out a few years ago.

I have a PDF scan of all important IDs/health cards/etc on a drive in my safe deposit box. It's also where I store my long term email/document archives.

I keep a mirror at home, which is what I update most frequently and any time I go to the bank, I just swap the external home drive with the one in the safe deposit box, go home and rsync the current data to it.

My safe deposit box key lives in a floor safe in my home which should survive even a gas leak explosion/tornado/etc.

Now that you can easily fit 3-6TB in an external enclosure, you can do some pretty flexible things with backups.

Here's my system.

Local 3TB drive in system, mirrored to 2nd internal 3TB drive
Nightly, I rsync that data to a 3TB mirrored NAS
Weekly I rsync that data to a 2nd 3TB mirrored NAS
Monthly, I rsync to an external 3TB enclosure via USB

When I go to the bank to deposit checks every month or two, I swap the 3TB external USB enclosure with an identical one in my safe deposit box.

Only costs me $50 a year for the safe deposit box, and I don't have to worry about my neighbors breaking anything.

Also, I have a 2nd manual version of my backup scripts featuring --delete for when storage starts to fill.

The artist draws everything in vector and often puts a lot of little details into each frame.
A vector viewer is available (swf) allowing you to zoom in and appreciate all the little details.

Check them out. Definitely one of the most artsy comics I've seen online.

+ - 2m Thunderbolt cables cost $50->

Submitted by Anonymous Coward
An anonymous reader writes "Look around and you’ll find that 2m Thunderbolt cables cost AUS$50, a significant jump in price over competing products like USB 3. This isn’t some sort of Monster cable-esque markup, it is part of the inherent issue with Thunderbolt. There are specific chips and firmware in the connectors, and the ability to manufacture cables involves licensing the technology. From what we have been told by contacts in the hardware industry, there are five such companies which are licensed to make Thunderbolt cables. This article looks at some issues with Thunderbolt."

The cache on a hard disk is often used as write cache - store incoming data in cache, leave actually committing it to disk until a convenient opportunity arises.

32MB of cache doesn't take that long to flush. 1GB, OTOH...

You're forgetting that a hybrid drive would be using NAND flash vs DRAM... NAND is a NVRAM and won't have to be flushed to disk in the event of a power outage. It is persistent.

That said, they may still use a little bit of DRAM cache in the drive.
