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 Iometer tests, which is configured to use 32 outstanding I/O's per target and random 50/50 read/write distribution, SandForce SSDs generally outperform the competition when tested with this large queue depth. The latest SATA 6Gb/s storage solutions lead the pack, and while the 240GB OCZ Vertex 3 Max IOPS Edition is on top with 83,117 IOPS, the 240GB Patriot Pyro SE solid state drive produced 76,745 peak combined IOPS. This high level of I/O is beyond the needs of casual users, and would certainly appeal to access-intensive computing environments such as database transaction servers.

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.

I've owned a Patriot Inferno for almost a year now and it's been very reliable. The Pyro looks like it's continuing a solid reputation for a quality product.

Great review, and I enjoyed reading about your benchmark selections and reasoning. This latest generation of SSDs sure provide amazing performance.

# Comparison Between Modelsredwolfe_98 2011-12-16 10:49
i would have liked to have seem a comparison of the performance of the 60 GB, the 120 GB and the 240 GB models of the patriot pyro SSD's.. i understand that if all of those were not provided, then they couldn't be tested.. from what i have seen, there can be big differences between the smaller and larger capacity SSD's..

to me, the prices on the patriot pyro SSD's look good, compared to what i have seen with other SSD's, which, incidentally, are too expensive, for me..

Thanks for your comment. To be honest, I would have liked to receive one of every capacity so they could be tested as well. Sadly, that's not how these manufacturers send samples. In terms of maximum performance the differences are very small, but those differences get big once the NAND gets filled (but not with the Pyro SE series because it uses synchronous NAND flash components).

to add to my last post (since i can't edit it), i should have said that the price on the 120 GB unit looks good, to me.. the price on the 240 GB unit is comparible to those from other vendors, which is too expensive for me..

Nice review. You should test these on AMD chipsets/mobos. You will get very different results, not only with the Pyro SE but all of the Sandforce controller used SSD'd. I have tested the Kingston HyperX and Vertex 3 Max IOPS and the Pyro SE. With compressed sequential data they get similar results as the SSD's on Intel chipsets using iStor. On an AMD board ( I've tested on SB850 and 9 series chipsets, using the AMD sata controller) and the 4K, 4KQD32, and especially random reads drops to 60% less than the Intel boards. The SSD's that have worked best for me and test well across the board are the Crucial C30, M4(Marvell contr) and Samsung 830(Samsung Contr.)These were 120gb drives. Just my findings for the AMD folks out there.

I agree with this comment as far as the need for testing hardware on more than one platform. Did you notice any stability issues when testing the Crucial M4 or the Samsung 830 on the SB850? I've been looking at both of these SSD's, after having experienced the "disappearing drive" issue with the OCZ Vertex 3 (which I've come to understand as a compatibility issue between the Sandforce Controller and the SB850). I'd love to add a 256GB SSD as the application drive for my system, but not enough to have to upgrade my mobo (and consequently my CPU): I just built this system 7 months ago.

"after only a few minutes I was booting from a restored Windows 7 System Image"
Can I assume that if I have already done a W7 install on a HD that I can use this procedure to move W7 over to the ssd if I purchase one? I am new to W7 and system image? Currently all I have installed on a new build is the W7 OS..Thanks

Do you reply to email also??? or do I check back here...guess I will find out if you respond to my email...preferred...thanks

Yes, you can clone from a hard drive to the SSD without re-installing Windows. See here:

# OffsetMergatroid 2012-01-17 17:28
SSDs requite a particular "offset" for the format. If this offset is not correct, you can end up writing to two blocks instead of one for every write, which will kill performance and reduce the lifespan of the SSD.

Some imaging software is offset aware for SSDs and some is not. If your software does not work properly with an SSD and you create a hard drive image, when you restore the image to the SSD you will have the wrong offset.

Some imaging software will use whatever offset is in the image. Under these conditions a restore will provide the wrong offset. If the image was made from an SSD in the first place, then it should restore the correct offset.

Some imaging software has been updated so that it will use the correct offset when restoring even a hard drive image to an SSD.

This all depends on the software. You MUST check your software and if necessary contact the publisher and find out how it handles offsets. If you restore a hard drive image to an SSD with the incorrect offset, as far as I know the only way to correct it is to completely do a fresh install of Windows 7. I have seen people claim they can correct the offset after an incorrect image restore, but I tried it and the performance was not what it should have been. I had to load the recovery console, command line interface and run the diskpart software to format the drive and apply the correct offset.

All that can be avoided in two ways:
1: Do a fresh clean install to begin with and windows 7 will do everything correctly.

or

2: Create and restore your hard drive image using image software that is SSD offset aware.

AS SSD Benchmark will tell you if the drive's not aligned to 4k boundaries. If that happens, best to purchase Paragon Alignment tool.
handy to have for anyone playing with SSD's, and you re-use it once you buy it. There's other ways to re-align, but for $30 the Paragon Tool will save you a lot of headaches.
