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 LSI-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:

Illustrated above are our Iometer tests, which are configured to use 32 outstanding I/O's per target and random 50/50 read/write distribution. The Intel SSD 520 Series solid state drive holds a narrow lead over the CoreRise Comay Venus Pro 3 SSD. LSI-SandForce SSDs generally outperform the competition when tested with this large queue depth, and the latest SATA 6Gb/s storage solutions lead the pack. SSDs using the PCI-Express bus offer some of the highest I/O we've tested, but even these SATA-based SSDs deliver far beyond the needs of multi-tasking power users and hardcore gamers.

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.

Pretty amazing. How long did it take for storage devices to catch up to the SATA 3 standard? Now after only a couple of years, storage devices are already near saturation for SATA6. LOL totally amazing. This thing can transfer 30GB/minute.

It will still be a wait for USB 3 devices to catch up to the USB 3.0 saturation rate so we can see the benefit of USB3 to something as fast as this device. I can't wait to see CF flash or something similar come into line with the USB3 theoretical. Most cards never got past a little over half of the USB2 specs.

Olin,

You say this drive is expensive, but I didn't see a price in the review.

I don't think now is a good time to be entering any 'expensive' SSD into the market.

Yesterday I saw a sub 140 240GB Vertex3 in the wild. I paid more than that (170) for my 128GB Samsung 830 only 6 months ago.
