Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
I would not run software RAID. It just doesnt seem like a good idea. I would just try to pick up a PCI RAID controller card.
The performance boost isn't that great anyways with RAID0. I barely notice the difference in everyday use for me. Transferring large files, you can tell the difference, but other than that it is barely noticeable.
