Hello everyone, I have a RAID0 configuration with 2x2TB hdds and I'm having a strange issue. Could be irrelevant, but I started defragging the HDDs a couple of days ago, and since then they are slow as hell (plus Defraggler said more than 1 day was needed to defrag). I have a Kingston HyperX 64GB USB drive in which I usually copy films and stuff like that, and it usually caps it at about 150MB/s. Now, when I try to copy a file from the RAID to the stick, it goes up to 10/30 MB/s. Installing a game is a pain, too. I installed NFS: the Run (15 GB game) and it took about an hour to complete. Another sign would be WinRAR, when I extract a file while in the drive the CPU goes up to about 20% (might be normal though). The strangest of the things, though, is the hdds speed benched by any benching program. Attached is ATTO benchmark's file if you want to see it by yourself. HD Tune Pro shows the same behaviour. Thanks in advance to everyone.
