OCZ’s RevoDrive X2: When A Fast PCIe SSD Isn’t Fast Enough

Benchmark Results: CrystalDiskMark Streaming Performance

We recently added CrystalDiskMark to our benchmark suite after discovering an issue with h2bench2’s write testing methodology and the way it interacted with SandForce-based SSDs.

For the most part, CrystalDiskMark corroborates the sequential performance seen in Iometer. The RevoDrive X2 and IBIS are both on par, followed by the RevoDrive. The only exception is the Vertex 2 versus X25-M battle, where the SandForce-powered Vertex 2 falls behind in CrystalDiskMark due to our use of random data in that test. For a more detailed explanation, see below.

It’s important to explain differences in the way that Iometer and CrystalDiskMark measure performance here. Iometer doesn’t use completely random data in its write test, giving the SandForce-based drives a large advantage. We configure CrystalDiskMark to use completely random data, however, which is far more difficult for SandForce’s DuraClass architecture to compress, and Intel starts to look significantly better in comparison.

The RevoDrive’s performance is more than halved, While Intel’s perceived sequential write performance doubles. This is enough to put the 160 GB X25-M just behind the RevoDrive X2.

Even more interesting is the margin separating the IBIS and RevoDrive X2, though, considering both of these devices employ very similar designs. According to OCZ, the results are indicative of what happens when the drive is in a very dirty state. There is a tool available on its Web site to secure-erase the card, returning it to a new state. However, that's not going to be an option for most users, so the significantly reduced write performance is actually something to keep in mind.

    Too much money :( will get the vertex 3 though :) or intel

    If only they could make SSDs cheaper ... Mechanical drives are still the way to go

    although i think sandforce's new controller won't be as fast as they claim, i really think it's gonna change the face of the ssd race by the end of the year

    and probably a new iteration of the revodrive as well... can't wait!! =D =D i need me a 160gb for less than $1/gb... that's how much i bought my raptor for like 4 years ago!!

    In related news, OCZ stock is up to $6.80 a share, rising 19%+ today.

    How does this compare to the new Z-drive R3?

    Yeah its really cool and i wish i had 1...or 2 lol but it just costs waay too much money, isnt really practical for enthusiast use until the prices drop

    You routinely use $500 graphic cards (GTX580) and $1,200 displays (2560x1600)in reviews. The price for this upgrade ($650)isn't any harder to stomach then those.

    Aye, but it's a little less tangible than exotic graphics configurations, too.

    a pci-e ssd seems good, I want one, MS word will run sooo much better

    i realy wish they would put a 7200 10000 and 15000 drive in there, all top of their respective class, just so we can get some prospective of how much an improvement these are over traditional hdds.

    Something like that is beyond anything any mechanical drive can hope to compete with, its even faster then a multi-channel directly connected SAN array. It looks to be one step away from a RAM Drive, if anyone can remember what those were.

    I am waiting to see if Intel's LightPeak tech will be used in the the storage arena(i.e. boot drives, etc). Seems like the SSD tech is evolving so quickly.

    I want one but will have to wait for the price to come way down.

    Do SSD's or the RevoDrive improve gaming performance at all?

    There is no way to use REVO, Modern Video card AND INTEL RAID ICH10R RAID 10 AT THE SAME TIME, the option rom spoace is used all up.

    DO not buy unless you do not ever want RAID through Intel ICHR10 !!!

    See link below

    REVO is not worth it!

    Hmm, a little off topic, but what is that Cooler Master UCP-1000W used for the test rig? It's in a strange spot on the CM website, and not in their regular lineup. I guess it's either brand new and not for sale yet? Or is that a legacy product?

    I've read the thread. If you boot from the Revo it's 100% safe to disable ICH RAID. The RAID support present on ICH can be replaced to Windows RAID. As discussed in that thread disabling PXE can also help.

    Why would anyone spend hundreds of dollars just to boot up 30 seconds faster, when they spend hours a day on the same computer?

    What I miss in the review: Is the RAID on the card "invisible" to the OS, as in, the OS sees it as a single drive. Or does the OS need to load a driver for the controller? If that's the case many Linux distri's will not be able to use it as a single drive.
