My experience: 30 computers(iI administer a small computer center)compute rcenter with 30 computers, each with two hard drives and two dvd-rom drives , the HD. The HDDs are sataSATA and they use the converters,. It's been 2 years from now and not a single drive has failed and neither have the PSUs. They They are safe because they are designed to draw more or less the same ammountamount of power than IDEsas IDE drives.
