Summary: I purchased this Sata hard drive to gain extra needed space. I upgraded to windows 7 and installed on my new hard drive. My computer runs a lot faster and now I have the needed additional storage I wanted. Samsung has a good name and they're 1 TB hard drive has quality that is hard to beat. I recommend this hard drive to anyone who desires a quality item.
Summary: I have 4 of these in a NAS set to raid 10. It has been running continuously for over 3 years without any disk failures. Throughput on 1Gbs network is indistinguishable from a single internal HDD. I also have 2 of these in an OWC Maximus Raid 1 external enclosure being used as a back-up/time machine for my main computer. That pair has been running for a year without any failures. I can recommend these drives without reservation.
