Enterprise Storage Bench - Microsoft SQL WeeklyMaintenance
Our final enterprise storage bench test once again comes from our own internal databases. We're looking at the stats DB again however this time we're running a trace of our Weekly Maintenance procedure. This procedure runs a consistency check on the 30GB database followed by a rebuild index on all tables to eliminate fragmentation. As its name implies, we run this procedure weekly against our stats DB.
The read:write ratio here remains around 3:1 but we're dealing with far more operations: approximately 1.8M reads and 1M writes. Average queue depth is up to 5.43.
Once again we see great performance out of the 910 here. The 800GB drives are significantly faster than the SandForce based drives from OCZ, but at 400GB performance is cut in half once again. At the 2.5" form factor Intel's SSD 520 is in the lead, followed by Toshiba's 400GB SAS drive.

Wow, fantastic review. Thanks for the good work Anand.quiksilvr - Thursday, August 9, 2012 - link
Considering the hefty price on these devices, anything short of AES-256 in this day and age is unacceptable (yes I know you can do software encryption, but hardware accelerated is much more secure)prime2515103 - Thursday, August 9, 2012 - link
I'm confused. Isn't AES-256 the same whether it's done in hardware or software? I thought hardware encryption just performed better (encrypts/decrypts faster).Rick83 - Thursday, August 9, 2012 - link
AES-256 is no safer than AES-128, according to somewhat recent cryptanalysis on the algorithms.madmilk - Thursday, August 9, 2012 - link
Hardware acceleration is probably for performance, even AES-NI can't keep up with multiple PCIe SSDs.And yeah, AES-256 easier crack than AES-128 now. Not that it matters, with computational complexity still at what, 2^99?
It's much easier to just kidnap the sysadmin than attack crypto.

Since you didn't mention which attack you are referring to, I'm going out on a limb and assuming you are talking about the related key attacks on the full AES256 / AES192. I don't know of any other attacks that work on all 14 / 12 rounds. You should be aware that while such an attack is widely considered impractical, it isn't even possible under many circumstances. You need some up front data that you can't always get. To keep in relation to this article, I'll limit my scope to on the fly encryption software as it is closely related to the encryption implemented on this device. Several on the fly encryption packages are known to be immune to this kind of attack (I'll single out TrueCrypt as a popular open source package that isn't vulnerable to related key attacks). As long as you are using a properly programmed encryption package for your full disk encryption, AES-256 is still "more secure" than AES-128.
That said, if you actually calculated the amount of time it takes to brute force AES-128, you'll find that PCs and possibly humanity will have become a long forgotten relic of the past. Of course, processing power changes, but not that quickly. A bigger concern would be attacks that successfully bring the set of keys down to a manageable level. For this issue, diversity is probably more important than bit length, assuming the brute force key set is sufficiently large (I.E. 2^128).

I always end up needing to be able to communicate directly with each "drive", which is usually problematic through a raid controller and software raid is invariably faster and in every case I've tried so far much, much faster.Araemo - Thursday, August 9, 2012 - link
Isn't this necessary for trim anyways? If the OS can talk to each 'drive', trim should work, and performance will stay good, right?web2dot0 - Thursday, August 9, 2012 - link
Hey Anand,Shouldn't FusionIO cards be part of this comparison? It will most likely destroy the 910.

http://hothardware.com/printarticle.aspx?articleid...Not according to this article. And ioDrive compared in this article is actually about 2x the price of either intel 910 or z-drive r4.
