Thank you for you answer. So I was hoping that it'll work.
I intend to use a cache/log device. That's why I'll use the speediest
sata port. The cheap SSD didn't work my old PC.
Under 2 weeks I had an error on it. The "scrub" showed me. I don't want
to deal with any disk error.
Intel 3500/3700 SSD is too expensive for me. Anyway thanks again.
