Sequential 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.

Iometer - 128KB Sequential Read

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.

Iometer - 128KB Sequential Write

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.

    That connector is called a MICTOR (not sure on the spelling). It's made to hook a logic analyzer up to and generally not useful for most people.

    Doesn't look like a MICTOR to me. A MICTOR has contacts aligned along the center, this one has contacts that are on aligned on opposite sides along the center.

    It looks like the Samtec version of the MICTOR. QSH series maybe. Same concept though. High speed, impedance controlled debug or board-to-board connector.

    Yes, I think you're right. Thanks!

    whenever you test ssd, you should still include a fast hdd as a reference point!

    Seconded. A VRaptor would have been a good idea. Also, can you RAID two of these like SLI vid cards?

    Intel clearly has RAID figured out. I'm guessing they're going to drop their on version of this thing in Q4 with 22nm flash and blow everybody else out of the water. I also wonder what the latency is like going through all of those bridges and controllers. PCI-e is supposed to be lower latency than SATA right?

    The problem with that is, that even the fastest 15k rpm SCSI drive would still be nothing more than a bar in most benchmarks, so not really that usefull and if you're interested in it you could always use bench.

    Though you have a point that it'd be a helpful reminder of the huge difference between HHDs and SSDs and would show that the differences even between the fastest/slowest SSDs aren't that important if compared to HDDs.

    OK, when can they shrink one of these onto an express card, so I can plug it into the PCIe slot on my early-2008 MacBook Pro (whose SATA interface is limited to 150 MB/s)?

    Your storage bench are very interesting and looks like most adequate storage test. Do you have any plans to make it available for other users? (for personal use)

    ps: sorry for poor English

    Is it possible to change the stripe size on the RevoDrive's internal RAID-0 in the SI BIOS? I did a little research myself regarding stripe sizes in SSD-RAID-0's and found that a 16kb stripe size is ideal for overall performance instead of the default 64kb (at least on Intel ICH10-R). With that configured a Vertex LE RAID-0 (x2) could easily come from around 40K to 80-90K in the Vantage HDD Suite.
