Summary: Best drives I could get for my ReadyNAS Duo v1. The speed upgrade from the factory drives is night and day. I can now watch and transfer videos/files simultaneously without lag or video stutter. Well worth it. Follow instructions and ensure backups have been performed prior to any drive upgrade/replacement. Enjoy!
Summary: First, a disclaimer; if you purchase this item and you want the P/N 0F12115, make sure you ASK for that specific P/N. They are often sold in a bulk lot with the 32 Mb cache, 3 Gb/s drives. While the performance difference is arguably marginal, the performance tests I read were for a very specific model and I wanted to make sure I got the exact one, which I did not get initially from two different sellers. You may or may not care, but just be advised.
Summary: Very large capacity and high performance, but just realize a few minor gotchas: 1) It's not very quiet compared to it's Seagate competitors. In very quiet rooms you can hear the platters wind up and down (and I mean *very* quiet), but beyond that you can hear the heads slam around not unlike hard drives of the late 90's. 2) Spool up times are kinda large.
Summary: I run (2) W2000 pro SP4 Workstations and use external Granite Digital Sata drives. Both Sata old type But the Hitachi Sata 2 GB drives move fast...real fast. Don't underestimate Sata 1... The IBM and then Hitachi drives are still the best in the industry. My 2TB drives on WK2 move faster than my modern quad and 5 core core stuff.
