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.
Looks like your Block size is set below your Stripe size. Do like DSee said above, set the block size in HDTune to 512k or larger. You're basically benchmarking a sigle disk in your array right now.
I've got 8 of these drives in a raid array so they never really spin-down, but they are some of the quietest drives I've ever used. I did also have one that was DOA and it had the click o' death sound...That one, you could hear spin up, then a loud click and die, then it would repeat that cycle...
