OCZ's RevoDrive Preview: An Affordable PCIe SSD
by Anand Lal Shimpi on June 25, 2010 2:15 AM ESTSequential Read/Write Speed
Using the 6-22-2008 build of Iometer I ran a 3 minute long 128KB sequential test over the entire span of the drive. The results reported are in average MB/s over the entire test length. All requests are 4K aligned.
The Intel ICH10R controller actually offers better performance here by a good amount. Even the old Z-Drive m84 is a bit faster than the new Revo, perhaps due to the use of four controllers in RAID-0 on that drive.
Write performance is a similar story. The two Vertex 2s in RAID-0 are faster thanks to Intel’s highly optimized RAID controller. The RevoDrive is still no slouch and what we’ll look at next is the real world impact of these results.

Seconded.The stripe size can have a dramatic impact on performance.
I'd also love to see 4KB random read @ QD 32, but maybe i'll have to wait for some other enthusiast to download CDM 3.0 and post a screenshot...
The sequential read scaling found was horrible, 290MB/s from 2R0 120GB SandForce drives is low. How about an ATTO comparison to show a broader spectrum of sequentials?

They should make the 240GB version with 4 "drives" in RAID 0, that could make it more interesting... and I guess no one would mind paying twice the value of the 120GB, $740 for a drive that can, at times be almost 4x faster than a Vertex 2.mapesdhs - Friday, June 25, 2010 - link
Since these are PCIe devices, did you guys try striping more than one of them by any chance?
Heh, looking forward to when we get RamSan-620 speed & capacity on a single card. :D

So how are these supposed to stack against other enterprise hardware companies? With no trim support, this would definitely kill the thought to purchase these.http://www.violin-memory.com/

if it is raided, does it support trim on the raid ctrl ?ggathagan - Friday, June 25, 2010 - link
Which part of "No TRIM, No Garbage Collection" confused you?RaistlinZ - Friday, June 25, 2010 - link
No TRIM is expected.But no garbage collection? Bleh. I'll wait until it at least supports GC. OCZ's reliability on their SSD's has been shoddy lately, which makes me want to hold off even more.

Oh goodie, I can't wait until we have a drive that's 10 times faster than the Intel x25-m and only costs 10 times as much! Maybe after that, we'll get something even faster, for even more money!!Seriously, the problem with SSD's is not that they're too slow, it's that they're too expensive. Drives like this aren't exactly helping in that regard.

I wonder if there would be any kind of noticeable im[improvement in sped if you put it on an ASUS p6t V2 and overclock the PCIe bus (any board with this function really)Very cool article *thumbs up*

$369 for 120GB£316 for 120GB
