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:

In our Iometer tests, which are 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 OCZ Vertex 4 SSD delivered the best combined IOPS performance we've seen from any SATA-based SSD with 83,494, followed by the Intel SSD 520 Series at 80,433 peak combined IOPS, then the Intel SSD 335 Series with 80,015. This 120GB OCZ Vertex 3.20 solid state drive kept pace with other SATA 6GB/s SSDs, but its lower capacity limited to only 32,711 combined IOPS.

It should be noted that nearly all modern SSDs deliver I/O far beyond the needs of multi-tasking power users and hardcore gamers, and would be ideal for workstation systems running utilizing virtual machines.

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.

"Would you buy a lower-capacity SSD because of costs, or save funds and insist on higher-capacity?"

At the moment I have an older OCZ SSD in my system which contains the OS and I also work with PC's that do not have an SSD. So I can easily compare how I perceive the speed increase in real life.

My next system will probably not contain an SSD at all. I think it simply is not worth it. HDD are so much cheaper and the actual, practical perceived speed increase when using an SSD is so minimal that I think it is not worth it at all.

I recently built a new system for a friend and after some consideration we both decided that he did not need to waste money on an SSD at all. Instead he invested it in an extra HDD for more storage.

I feel the price of a 240 Gb SSD at $220 is atrocious. I like the SSD technology very much and have nothing against them at all. I would buy them if I had a room full of money, but I do not. I'd rather invest the extra money in a graphics card for example. But if you have ample money, by all means buy an SSD. It is wonderful tech.

I'm sorry OCZ. I just do not trust your brand with SSDs at the moment. You'd have t lower the price down to $0.50/GB before I decided to purchase one.

$0.50/GB is really hard to find for even a lower end SSD. But other than that, I am curious what your hesitation is with OCZ. I hear a lot of bad things about them however in 3 SSDs of theirs I have owned, Vertex 1, 2, and 3, I have had relatively few issues. One issue was easily solved with a firmware update and the other was covered under warranty, just shy of 3 years the drive had. I'm wondering if maybe there is some issue specific to their newer drives you are having that I'm not aware of. I am considering getting another drive this summer and would appreciate any heads up you can give me. Thanks!

I am also wondering WHY these reviews and the POS so NOT include the hardware for installation. OBVIOUSLY, the 2.5 inch, et al, will NOT fill a 5 inch slot, or even 3.5 inch. SO you have to get adapters or a rail or some other intermediary item to affix the little card (SSD) to your unit. It is a major agro to order some hot new device and NOT be able to use it until you get the "recommended" add-on items, without which you cant install. And as to speed, with 6/ HDD available. Seagate comes to mind with Raptor @ 10K speeds and two cashe levels. why would the typical home user, even hard core gamer, really NEED SSD? I would put Rator up against this DDS, and @ 80USD it is a great buy. I have a suggestion for SSD MFG, to improve their offerings, if they would be interested. I can be contacted at email.

SSDs don't need all four points mounted like a hard disk drive requires, because nothing moves or vibrates. You can match up one screw hole and mount it... seems to work just fine.
