Good things about Dell

When I purchased my laptop computer about six months ago, I ordered it from Dell's UK website. I decided that I wanted a good sized hard drive (by laptop standards anyway) and I therefore clicked on the "60GB" option. There was also an 80GB option, but the standard option was less than that - I think there were 30GB and 40GB options as well. (80GB is still the maximum for my model, although there are hard to find 100GB drives on some other models). I do not recall if the speed of the drive was specified on the online order form, but if it was I did not pay attemtion. Most laptop drives are 5400rpm (or sometimes 4500rpm) and I guess I just assumed that it would be one of these (and to be truthful I didn't think of the issue at all).

In any event, when I recently took the drive out of the computer so that I could put the drive from my old laptop in to test if it still worked, I noticed that the drive was a Hitachi 7K60. This runs at 7200rpm and is generally considered to be the best laptop drive available in terms of performance. Dell supplied me with a really top notch component there, for which I thank them.

They didn't draw my attention to this in any way though. Perhaps they have a mixture of suppliers and not everybody got a drive this good. Or perhaps they wanted people to pay extra for an 80GB drive, and didn't want to draw attention to the fact that the 80GB drives they were offering were actually lower performance than the 60GB drives. (There are no 2.5" 80GV drives that I know of that run faster than 5400rpm).

And why do hard drive speeds always seem to come in multiples of 900rpm. (This is the same as saying multiples of 15Hz, which is perhaps a slightly rounder number).

Update: Of course, many of them actually come at 4200rpm, which is not a multiple of 900. Me stupid.
