Stressdrive is a Mac OS X command-line tool meant to verify correct operation of a drive. It does so by filling a drive up with random data and ensuring all the data can be correctly read back.

It was written to verify correct operation of de-duping SSDs, but it be used with normal HDDs or any rewritable block storage device.

DANGER: stressdrive will overwrite, without warning, all data on the given drive. Be sure to double-check the drive you're aiming it at (Disk Utility.app > Select Drive > Info > Disk Identifier).

Architecture
Nimbus.io uses parity striping to spread data across many servers redundantly - providing bulk storage with equal reliability and less than half the overhead of replication based storage systems.

Documentation
The API is similar to S3 or Rackspace Cloud Files - favoring JSON over XML. For easy portability, we supply libraries to use Nimbus.io as drop-in alternatives for the most popular libraries to access competing cloud storage platforms.

The server and client components are all free and open source software. The server software is made available under the AGPL license. Clients libraries are available under LGPL.

Pricing
$6 per 100GB of purchased storage. Transfer in is always free. Transfer out is $0.06/GB. PUT and LISTMATCH requests are $0.01 per 1000. Other requests are $0.01 per 10,000 or free.

At the Non-volatile Systems Laboratory we have designed a procedure to bypass the flash translation layer (FTL) on SSDs and directly access the raw NAND flash chips to audit the success of any given sanitization technique. Our results show that naïvely applying techniques designed for sanitizing hard drives on SSDs, such as overwriting and using built-in secure erase commands is unreliable and sometimes results in all the data remaining intact. Furthermore, our results also show that sanitizing single files on an SSD is much more difficult than on a traditional hard drive. We are working on designing new FTLs that correct these issues and also exploit properties of flash memory to maintain performance while sanitizing the flash drive.
