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.

If you re-flash the card with SIL3124 non-RAID BIOS, it should look just like 2 SSDs, and TRIM should work.oshato - Monday, June 28, 2010 - link
I too would like to see the pass through configuration ( non-raided ) tested for TRIM support and db IOPS #s. Curious how feasible this would be for a zfs ZIL in pass through mode.marraco - Monday, June 28, 2010 - link
I'm worried about video performance in single and dual setups with this SSD working.marraco - Monday, June 28, 2010 - link
What about boot time?the RAID controller should increase the POST time, and that frequently destroys the boot advantage of SSD under RAID.

Does anyone know if this card will work in OSX? I would like to know specifically if it will run in an Xserve.clarkn0va - Tuesday, June 29, 2010 - link
I think there's another, if less common need for this: places where you lack drive bays or SATA ports. Some examples:-SFF servers, most of which accommodate only 1 3.5" drive or 2 2.5" drives. Would be nice to have a little 1U Atom board running a small NAS/application server and cram a little more storage in. I have a mini-ITX server doing nfs, torrents, voip, monitoring, etc and would love to move it to a small rack, but until now couldn't justify the loss of drive space. With the OS and applications running on a RevoDrive, bulk data can live on a pair of 2.5" drives and we're all good.
-Enterprise servers. I'm shopping out a terminal server at work and the cost of purchasing drives with your new server is laughable. The highest-end SLC drives from Intel and OCZ cost less than the OEM-branded grab-bag the server vendors are offering. I would much rather put my own drives in there, thanks, and cruising ebay for compatible drive caddies just feels wrong. pcie slots, on the other hand, come with the server without paying some stupid OEM storage premium.
Now the questions.
1. The article says you configure your own RAID-0. Will the utility also let me configure it as RAID-1 if I want?
2. Anybody know what it's like to try to boot Linux from one of these devices?

Nice reading, thanks for another SSD review.btw, on Installation and Early Issues you have a typo:
I headed into the Silicon Image BIOS, asked to recreate the array, specified the entire 233GB

What are the lengths of these 2 cards? I'd really like to put one in a case that only takes half-length cards.LightningCrashTSI - Wednesday, July 14, 2010 - link
FTA:"The OCZ RevoDrive will offer lower CPU utilization than an on-board software based RAID solution thanks to its Silicon Image RAID controller,"The Silicon Image RAID controller is a software-based RAID controller as well.

The important question is, which Firefly episode?Was at first very disappointed to hear about this drive, but thanks to your review I see it would only have made a small effect on actual usage, so I don't need to regret recently getting OCZ Vertex II 120GB too much.
