From: M-M on 24 Jan 2010 10:06 I have a 2.5" SATA enclosure and want to get a HD for it. Will a 7200 rpm HD matter if the drive is used as a startup disk, or does the USB connection cut down the speed so there is no advantage? Will a 7200 rpm HD in an aluminum enclosure get very hot? Or should I stick with a 5400 rpm? Finally, as far as reliability is concerned, I believe Hitachi > Seagate > WD. True? tia, -- m-m http://www.mhmyers.com

I shutter to think of the horrible performance you'll get form a USB connection for a startup drive. Yuck! Why not use an internal drive for the startup drive? > Will a 7200 rpm HD in an aluminum enclosure get very hot? That totally depends on the drive you put in it. But in general, 7200 RPM drives do run warmer than 5400 RPM drives. > Or should I stick with a 5400 rpm? > > Finally, as far as reliability is concerned, I believe > Hitachi > Seagate > WD. True? In my book it's Seagate > all others. Of course that's just my opinion, and you know what they say about opinions. : ) -- Send responses to the relevant news group rather than email to me.

OK then, but is there any advantage to purchasing a 7200 rpm drive to use in a USB enclosure? Will it back up faster (than a 5400) if the internal is 5400? Or is the chain only as strong as the weakest link, as they say? -- m-m http://www.mhmyers.com

My guess would be that the internal ATA 5400 RPM drive will outperform the 7200 ROM drive handicapped by the USB 2.0 connection. -- Tom Stiller PGP fingerprint = 5108 DDB2 9761 EDE5 E7E3 7BDA 71ED 6496 99C0 C7CF |
