SSD, TRIM and IOMeter

For two years now, SSDs are continuing to democratize. Although their progress in our machines can be some held back by prices of the MLC who remain at high levels, they scored a dramatic increase in speed of PC storage system.

While new controllers coming onto the market, we wanted to review the fragmentation SSDs, TRIM, how it is used in Windows 7, as well as IOMeter, a powerful synthetic test software but can be misused when it comes to testing SSDs.

Back to the Future

We published since September 2008 seven articles dedicated to SSD

– SSD Comparison: Intel, OCZ, Samsung, Silicon Power, Super Talent – September 8, 2008
– Mtron MOBI 3500 – 1 December 2008
– Samsung SSD MLC 64GB – December 8, 2008
– SSD 2009, act 1: OCZ Apex and Samsung PB22-J – March 16, 2009
– SSD 2009, act 2: OCZ Vertex and Indilinx Barefoot – April 22, 2009
– Intel X25-M, round 2: 10 compared SSD – May 5, 2009
– Intel X25-M V2 (Postville) – July 31, 2009

from the first, we had pointed to a greater or lesser phenomenon in the SSD model, which was a performance degradation over the use of SSD. The TRIM function, embedded in Windows 7 since its release was expected as the messiah because it was supposed to prevent such wear. What about in practice? With some delay, it is true, we return to the opportunity to put to the point of our new SSD testing protocol on the TRIM and the impact it has on some software such as IOMeter tests.
