That's basically my doubt, it's for mass storage so either would be OK but I am wondering if the 5900 will last longer. Will be buying a Seagate 2TB hard and either are the same price here. Thanks
You will find the 5900 rpm drive MUCH slower in all spects than a 7200 rpm drive. They should last about as long. I was reading the 5900 rpm drives seem to have a high failure rate.
