But I found out that they suck in terms of reliability, so I switched to Hitachi. There was this 5900RPM model about four years ago, I think - I believe it was almost the only low-RPM one Hitachi ever did; they support it, too. And I have a 500Gb 2,5" Hitachi Travelstar bought a year or two later, and even they support it! So, I guess I was right; apparently, Hitachi is not into the castration business... Has anybody seen any Hitachi without TL;DR ?.. -- darkpenguin
