From what I know the "core" FW for all the SF drives is the same. Based on the contracts they have, some manufacturers might get some features or limitations ( which is why some SF drives were / are limited to 10k IOPS for example ). Many manufacturers seem to have their own HW design for the drives, but as far as I know they all had similar stability problems which were fixed with FW updates. Considering this, I think it's pretty unlikely ( but not impossible ) to solve your issue by getting a SF drive from another manufacturer. If a newer IRST doesn't help you, try disabling power management features from your BIOS and / or Windows and see if that help you ( after doing the changes please run WEI - windows experience index). If nothing works, you can try a RMA ( the link is on the left ).
