[NAME] The Studio XPS 8100's SATA interface is SATA 2 (3 Gbit/s), but SATA 3 (6 Gbit/s) drives are backward compatible. The Seagate 1TB BarraCuda 72000rpm 64MB should work fine.
Hoping to find suggestions & recommendations for a replacement internal  hard drive for my trusty Studio XPS 8100 running windows 10. I'm a pensioner on a budget and once the Dell XPS desktop started clicking on start up then failed to start I reckoned another hard drive required - 1TB 3.5" 7200 rpm SATA111. Ive not keep up with lastest HD's should I be OK with Seagate  1TB BarraCuda 72000rpm 64mb but has SATA 6 gbs? Hope the forum can help me on this matter. Thanks
