Finally Intel brings TRIM to SSDs in RAID arrays

Enlarge

(PhysOrg.com) -- Intel will add TRIM support for RAID0 in its upcoming drivers in Q2 next year. The TRIM feature will be enabled for RAID0 setups in Intel’s upcoming RST (Rapid Storage Technology) 11.5 driver. For technologists working with SSDs, file under Great News. User forums for SSD users have had their share of polite questions and weary answers: "So is TRIM supported in RAID now?"

Answers have been well meaning but confusing: "Yes but" or "It Depends" or Nope. Users in the past had spread word that RST drivers supported TRIM on RAID but then there were clarifications that this was only if the user went for "AHCI" mode. All that blur and disappointing answers took another turn this month with a discovery by StorageReview of a certain note #2 on TRIM support across multiple RAID levels.

Intel RST 11.5 is expected to arrive in Q2 of next year with support for Windows 7 and Windows 8 systems. Intel's RST 11.5 release date has not been confirmed but observers assume the release will be in step with the launch of Windows 8 in Q2 2012.
