OCZ RevoDrive X2 Review: Killer SSD Performance

12 thumbs up


The RevoDrive X2 utilizes a somewhat uncommon melding of current generation and legacy technologies to achieve its 740MB/sec max read and 720MB/sec max write performance specifications.  The base SSD array of the design starts with a match that was apparently made in heaven (and who knows, maybe they'll be wed some day?); Intel NAND Flash and SandForce's 1200 series SSD controllers.



As we work our way down toward the edge connector of the card, however, there is a Pericom PCI-X to PCI Express bridge chip and the chip controller under the OCZ "R" sticker is a Silicon Image 3124 PCI-X RAID controller. 

 

This chip may be dated, as is frankly the PCI-X interface, but this is a hardware-based RAID controller, and as is the case with OCZ's new IBIS drive, the inherent latencies of bridging from PCI-X to PCI Express are virtually hidden. The net-net here is that OCZ not only benefits from the lower cost SI RAID controller, as well as lower density/lower cost Intel NAND Flash, but combined they offer a price/performance curve that, as we came to find out is down-right impressive.

 
 

There are still a few small caveats with the OCZ RevoDrive X2 as there is with the first gen RevoDrive. The drives DO support idle garbage collection, but do not support AHCI nor the Windows TRIM command. As such, you'll be relying on the four SandForce SF-1200 chips on the RevoDrive X2, to keep the card running at its specified performance levels after repeated reads and writes.  Perhaps this sounds like a gamble and we haven't had enough time with product to give you a solid understanding of it under long-term, real-life test conditions, but we'd venture prospective customers of the RevoDrive X2 will be in good hands with SandForce's robust garbage collection algorithms keeping things neat and tidy on the drive.

It's too bad I could only vote 'thumbs-up' once for this thing.

What a truly awesome upgrade for a PC. I wish that I could afford it.

As I've mentioned before,....what a nice addition to a giveaway prize this would make!

What a prize it would make all by itself in one of your HH contests. (probably the only way I could ever actually own one of them)

Maybe we'll see a gradual fall in the prices of these things and I'll get one a week before I die, so then I could die happy! Stick out tongue

When it will actually BOOT from more than SIX Motherboards on the market we can talk...  From OCZ site

 

 

Note: Before installing the RevoDrive it is important to check the settings/capabilities on your motherboard. If you plan on using the RevoDrive as a boot drive please check that your motherboard supports boot over PCI-E. Please check with your motherboard manufacturer for the latest platform information and BIOS updates. If you have any installation or compatibility questions about the RevoDrive, please visit our forums or call OCZ Customer Service for recommendations.

While the RevoDrive will simply plug and play for the vast majority of platforms for these particular motherboards OCZ recommends the following:
-Asus Crosshair IV – Please check with motherboard manufacturer for BIOS update to enable boot over PCIe.
-Biostar T-Power I45: RevoDrive is only detected in Slot 1 AND only if a PCIe GPU is used. 
-DFI DK-X58-T3EH6: Not detected in PCIe Slot 2 (x4 slot).
-EVGA X758 SLI – Please check with motherboard manufacturer for BIOS update to enable Boot over PCIe.
-Gigabyte GA-890FXA-UD7 Not detected in slots 1,3,4 (it is detected in 2,5,6)
-XFX 780i SLI – Bios must be upgraded to P09 (or later).

Well, I can tell you I dropped it into a Gigabyte board on that list for my testing and it had zero problems, as did the RevoDrive first gen card. Not sure why they have that short list up there. I will ask... I think it's pretty misleading though. This is just a standard PCIe X4 card here, nothing fancy or tricky compatibility-wise.

It only has to boot from the one that I'M USING, thank you. (If it doesn't,......then I'll deal with it) Big Smile

Of course I like it!  More power to HH.

Yeah, I knew that.

But if Newegg gets the hits on that page, it translates into HH getting some exposure,....................That's what I meant.

BZobisch, We just got this in from OCZ on the topic of compatibility....

"We see how the wording could have been confusing, so we have updated the product page to make it more clear:

While the RevoDrive X2 will simply plug and play for the vast majority of platforms, the following issues may arise when installing on these particular motherboards

http://www.ocztechnology.com/products/solid-state-drives/pci-express/revodrive/ocz-revodrive-x2-pci-express-ssd-.html "

So, that was a short list of boards that it might have issues with actually, NOT a list of boards that it will work with. Good news for you I'm sure. :) Good catch though and I was happy to see OCZ respond so quickly.
