Last week I have purchased a WD 2TB Green Drive as well as a non-raid capable raid card Rosewill RC-212; since my older PC (WinXP32, Celeron D, 1GB RAM) does not have SATA ports. I have installed fresh drivers form Rosewills’ website even though they are not needed for non-raid configurations. The PC recognized the card right away as well as the HDD. The write speeds are as expected, however the read speeds are between 300KB and 2500KB. I cannot figure out why the read speeds do not exceed 2.5MB? I have plugged the HDD as an external drive via USB and the read/write speeds are as expected. Anyone knows why and how to fix it? Update: I have tried 1TB WD green drive (1.5-year old) and it works as expected. Update 2: I have just spoken with Rosewill tech and he said that using PCI card and such a large drive it is expected to be slow. Personally I believe it is B.S. You? P.S. for moderators: I have similar thread under storage and networking, but it no longer applies as such issue. Please delete it.
