Windwithme mentioned several times when sharing SSD Raid 0 test.
That moment, Intel Rapid Storage Technology didn't support Raid 0 Trim mode. So the speed would drop after using for long time.
Few months ago, Storage Technology Drive 11.5 released and official support Raid 0 Trim.
This is really a good news for Raid 0 mode users.
It also pushes SSD further performance and applications to wider range.
Intel has enabled TRIM support for SSDs in a RAID 0 setup. The long-anticipated functionality finally appears to be working as expected. TRIM prevents performance degradation of the solid-state drive, by erasing unused data blocks, thus preventing empty data blocks from running out. This allows the SSD to perform write operations to cells data has already been written to without any delays. This technology was hard to combine with RAID as the RAID-controller complicates direct communication with a solid-state drive. Intel has now solved this issue.
It's possible to use TRIM combined with RAID 0 if you have a 7-series chipset Intel motherboard and a RAID opton ROM, version 11.5 or up. The RAID option ROM has to be added to the motherboard's BIOS by Intel's partners. Updates to add this functionality have yet to be released. Users are also required to have at least version 11.5 of Intel's Rapid Storage Technology driver. Lastly, Microsoft's Windows 8 operating system is required, although Real World Labs has already shown that the feature should work in Windows 7 as well.
