OCZ RevoDrive 3 X2 Conclusion

Iometer IOPS Performance

Iometer is an I/O subsystem measurement and characterization tool for single and clustered systems. Iometer does for a computer's I/O subsystem what a dynamometer does for an engine: it measures performance under a controlled load. Iometer was originally developed by the Intel Corporation and formerly known as "Galileo". Intel has discontinued work on Iometer, and has gifted it to the Open Source Development Lab (OSDL). There is currently a new version of Iometer in beta form, which adds several new test dimensions for SSDs.

Iometer is both a workload generator (that is, it performs I/O operations in order to stress the system) and a measurement tool (that is, it examines and records the performance of its I/O operations and their impact on the system). It can be configured to emulate the disk or network I/O load of any program or benchmark, or can be used to generate entirely synthetic I/O loads. It can generate and measure loads on single or multiple (networked) systems.

To measure random I/O response time as well as total I/O's per second, Iometer is set to use 4KB file size chunks over a 100% random sequential distribution at a queue depth of 32 outstanding I/O's per target. The tests are given a 50% read and 50% write distribution. While this pattern may not match traditional 'server' or 'workstation' profiles, it illustrates a single point of reference relative to our product field.

All of our SSD tests used Iometer 1.1.0 (build 08-Nov-2010) by Intel Corporation to measure IOPS performance, using a SandForce-created QD30 configuration: 4KB 100 Random 50-50 Read and Write.icf. The chart below illustrates combined random read and write IOPS over a 120-second Iometer test phase, where highest I/O total is preferred:

Iometer_Random_4K-IOPS_30QD_Results.png

In our standard Iometer test which uses 32 outstanding I/O's per target and a random 50/50 read/write distribution, SandForce SSDs generally outperform the competition when tested which a larger queue depth. PCI-Express storage solutions lead the pack, followed by the latest SATA 6Gb/s SSDs. Using a single Iometer target with 32 I/Os didn't separate performance results for the RevoDrive (X2) series by very much, which is why OCZ offered a suggested setting that increases the workload with two workers on two managers using 64 I/O's each. Using two workers on two managers and increasing workload to 64 outstanding I/O's produced a massive 226,470 combined IOPS with the OCZ RevoDrive 3 X2 PCI-E SSD, effectively doubling output over our standard Iometer test configuration for SandForce SSDs.

* Since there are multiple managers and workers assigned, we're unable to save an Iometer configuration file for visitors to compare with. Here are the steps given by OCZ:

  1. Launch Iometer 2010 (version 1.1.0-rc1)
  2. Disk Targets tab:
    a. Create two managers with two workers for each manager
    b. Enter 16000000 into the "Maximum Disk Size" field
    c. Change "# of Outstanding I/Os" to 64 to emulate multi-core CPUs
    d. Keep "Write I/O Data Pattern" at "Repeating bytes" to represent a typical database data pattern.
  3. Access Specifications tab: create a 4KB 100% write, 100% random test profile
    a. Create 4KB transfer request size.
    b. Select 100% random distribution.
    c. Select 100% write distribution.
    d. Set I/O alignment on 4KB.
    e. Add the test profile to "Assigned Access Specifications."
    f. Make sure that you assign this access specification to each worker
  4. Test Setup tab: Change Test Setup
    a. Choose 5 minute run time.
    b. Select "Cycle # Outstanding I/Os - run step outstanding I/Os on all disks at a time.
    c. Change "# of Outstanding I/Os, Start #1, End # 64 or 128".
    d. Under "Result Display" move the bar to 30 second update frequency.

In our next section, we test linear read and write bandwidth performance and compare its speed against several other top storage products using EVEREST Disk Benchmark. Benchmark Reviews feels that linear tests are excellent for rating SSDs, however HDDs are put at a disadvantage with these tests whenever capacity is high.

Those speeds are absolutely insane, cant wait for this level of SSD to filter down into the more affordable drives.

Not that it's of any real importance but would be interested to know just how quickly this could boot into Win7.

Ehm, do you mean seconds rather then minutes?

In which case, hot # that's fast.

i bought the first gen 120GB (x1) last year which is only 1xRAID0
(550MB/sec) ... windows 7 64 boots in around 24seconds
(ASUS Rampage III Extreme & Intel Core I7 980x at 4GHz)
Also bought several X2 series for my workstations at office, they
do almost the same startup times for windows - dont think it will get
any faster than this but hey - getting my fist coffe takes longer
than 24secs so i dont care!

240GB: RVD3X2-FHPX4-240G $2,549.95NZD
480GB: RVD3X2-FHPX4-480G $3,304.81NZD

for that sort of money I could buy 4x 120GB SSD's + an x4 PCIe SAS/SATA6Gbps raid controller for $1,866.07 and I'd still have plenty of money left over for a really descent PC to put it in

The 240GB is here around ?580,- that should be around 970NZD.

#tweakers.net/pricewatch/287789/ocz-revodrive-3-x2-pci-express-ssd-240gb-240gb.html#tab:prices

I don't know how much they will charge you for shipping it to New Zealand:P

tweakers.net is in German and they show ?590 which = NZD $1,021.68 and that's still stupidly more than I'm willing to spend even without PnP added

so this is a plus "+ SandForce SF-2281 processor supports TRIM, SMART, and RAISE"

but this is a minus "- SCSI architecture prohibits TRIM with Windows OS"

why even mention the + if it doesn't work

It works, just not with the current Microsoft Windows driver. There are other operating systems that could be used, and Windows could offer support in the future.

So isn't that another minus ie: hopeless for use with Windows as it wont last long without the use of Trim

In real use, a computer would rarely if ever reach 64 que depth. Usually its just 1 or 2 but mostly 1 with a quick SSD. The quicker the drive the lower the QDepth in real use. So the real number is probably a QDepth of 1, testing with a high QDepth gives irrelevant numbers if your focus is real use. This Revo drive is no faster than my Vertex 2 SSD in "real use".

It depends on what your "real use" is. Sitting in your desktop machine, probably not much difference. Sitting in a database server being hit by 100 users, yeah, it's going to make a difference.

Yeah, damn right!
However, in this article, I wonder which SATA controller would throw up 3 or 6 GB/s...it's 3 or 6 Gb/s afaik. On the other hand, the 8 GB/s of an 8x v2.0 PCI-x are more or less enough for those beasts...

PCI-e, not PCI-x. I'm falling asleep this morning.

Would really like to own one of these, but it's so far out of the range of my spending that I'll probably not have one until they're old news, replaced by something far larger and much faster.
I do have a few OCZ 'Agility' and 'Solid' SSD's and I'm happy with their performance and prices.
I see OCZ as a good choice in SSD technology.

Pretty good review on this drive. I've been considering this one for my first SSD based i7 2600 desktop and you guys have sold me one.Costs only about AU $660 (for the 240 GB one). I expect this to be a very good asset for a video editing app. Cheers.
