10/28/2009: Woops! Intel has pulled the firmware. Check out our news story to find out why.
Intel today released new firmware for its 34nm X25-M SSDs.
New Firmware: 02HA; Old Firmware: 02G9
The new firmware supports TRIM. This feature requires Windows 7 with Microsoft AHCI drivers. Intel drivers don’t support TRIM yet. For Windows Vista or XP you have to use the Intel SSD Toolbox, which supports TRIM.
The TRIM attribute of the ATA data set management command synchronizes the operating system’s view of deleted files with those that are deleted, but not erased on the drive. TRIM tells the SSD which data blocks are no longer in use. This helps stabilize the performance and health of the SSD over time.
For the tests we set up a Windows 7 system on our standard storage test platform. We used the Microsoft AHCI driver to support TRIM.
Drive performance is much better with the new firmware. Also after torturing the drive with IOMeter. The sequential write performance in used state areas is in the close to that of the former new state areas, the numbers still decrease but not near as much. Random reads and writes in our database benchmarks double. Very impressive. Workstation benchmarks also double and Webserver and Fileserver numbers increase significantly.
Early adopters who bought the first X25-M will not get a firmware update. Very sad.
- 30min idle time for triming the drive
- Second run of H2benchW
- Second run of IOMeter
The new firmware provides very impressive numbers and takes SSDs to a higher level of performance well beyond HDDs as system drives in desktop computers.
