I have several SATA 3.0GT/s HDD in my PC. manufacturers say that SATA 3.0GT/s should deliver up to 300MB/s but testing my SATA drives by copying a 5GB .iso between them i only get 55MB/s. When I transfer a 1GB .iso the transfer speed is 70MB/s so it seems the smaler the file the faster the transfer? between a SATA and a PATA drive i transfer 27GB at 33MB/s
This is all according to Windows Vista’s calculations.
All drives has caching enabled.
Are these speeds normal?
Are these speeds acceptable?
Is Windows Vista Accurate?
Can i do anything to improve transfer speeds?
the drives are NOT in Raid and all operate independantly
