I use an HP NAS with 6 drive bays that raids the drives 6x1.5 = 9 terrabytes right now i am at half of that 4.5 3x1.5 and it has a esata port I connect the too and the hr22 almost had a cow but now I have so much space I dont know waht to do with .
WD and Seagate make great drives stay alway from Hitachi drives they are good but noisey
