I have a custom built rig that has 2 storage drives.

for OS: Western Digital 1.0TB HARD DR 64MB

for other stuff: Corsair Performance 3 128GB (SSD) [ expected read speed: 400 mb/s ]

The system was incredibly fast for a couple of months, then one day i was playing a game then it started to get buggy (some sounds and objects disappearing), i stopped the game and the system seemed to be unstable so i had to shut it down, next morning i couldn't start it up, it was saying something about corrupt device.

I formatted both disks and installed a fresh copy of windows, all i can say that since that day the system was never like before, it takes 10 minutes to boot up (the icons and desktop slowly appear). but once it's done the slowness isn't as noticeable.

Here's my benchmark on the HDD ( read speed - write speed ):

And the SSD:

Anyone knows what could be the issue?
