Comment: Re:We don't need density! We need longer life! (Score 1) 39

There's no reason to use SLC these days really... Once you start writing in large density with intent on retaining data for some period of time, you'll be striping that data across 10-100 SSDs... The combined wear-life even with cheaper MLC drives still puts you up over 100 years for most products.

It's pretty easy to take the Drive Writes Per Day (DWPD) or PetaBytes Written (PBW) for the drives and add them all up... most any install will 10+ drives will outlast any standard 5 year hardware refresh cycle.

Disclaimer: I work for a large flash company and have been selling this stuff for the last 5 years.

Comment: The problem with this article... (Score 1) 68

...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.

by AcquaCow (#46882357) Attached to: Ask Slashdot: How To Back Up Physical Data?

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.

Any references for that? Even if true how the hell is that relevant, Assange is wanted for questioning on a set of charges that are pretty serious and merit extradition to Sweden. The UK has a strong history of extradition to the US, including of UK citizens so lets not think Assange was 'safe' in the UK. Isn't the reality that Assange is a bit of a douche and just wants to avoid questioning on this topic and is throwing about FUD and pretending to be a martyr to deflect attention away from the allegations.

For a man who preaches openness about the world he sure likes to hide behind things.

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.
