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 240GB OCZ Vertex 3 Max IOPS Edition with 83,117 IOPS, then the Intel SSD 520 Series At 80,433 peak combined IOPS. This 240GB PNY XLR8 PRO solid state drive kept pace with the leaders, delivering 74,179 combined IOPS. All of our top performers deliver I/O far beyond the needs of multi-tasking power users and hardcore gamers, and would be ideal for systems running several 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.

I just checked NewEgg for the length of warranty on all 3 sizes of these SSD's that you've listed.
They each have a 3 year warranty. Not 5 years as you've stated.
NewEgg also doesn't even sell the 240GB XLR8 Pro SSD. The link you gave is for a completely different PNY SSD.

Page 3 states that if you register the drive at PNY you get an extra two years.

I mention three times how registration at the PNY website will extend the three-year warranty to five years. A little reading goes a long way.

Er, you didn't check carefully enough. PNY has ALWAYS extended their SSDs' warranty an additional 2 year if you register, making it 5 years total. This was clearly stated on NewEgg. Duh.

And yes, NewEgg did sell the 240GB XLR8 Pro SSD in November of 2012, when you posted that message. I know because I bought and installed three of them. And now,a year later, it's on sale for $129.

how has the quality of this product held up the past year? is this a steal at $129?

The PNY XLR8 PRO has been a SOLID performer, with no problems whatsoever. The 128GB version is only $80 after discounts, but I recommend something at leat 240GB or larger.

# XLR8 is OK by me,.....realneil 2012-11-06 06:23
Good review,....I'll buy one or two of these when the prices relax a little.
I bought a few XLR8 GTX-570s and they have turned out to be excellent video cards.
