hi guys,

(1) do you known that "Harddisk drive" have "one disc/platters, double disc/platters or third disc/platters?

(2) if choose harddisk, choose one disc/platters is good performance than third disc/platters?

(3) also, how to known that harddisk is design "how many disc/platters. and Each disc/platters = GB size?
harddisk label / brosure found /or some harddisk software test?

(4) I need buy new "500GB" SATA2, 3.5" desktop harddisk, can suggest (only ONE platter) harddisk model to me?


thanks!

there is no speed difference if you have 1,2, or x platters. Speed all the same.
Buy Seagate.

You are better off with Hitachi or Samsung. I do not use Seagate, Maxtor, or WD anymore at all. I have too many problems with them. I use mostly Hitachi here.

I get allot of samsung problems. But to be fair Hitachi seems to be the least problematic now a days.

The point is, they are all going to fail. If you ask 5 techs, you'll get 5 different answers. Whatever you buy, just back it up and all will be fine.

My $.02 is for Samsung.

The access times may not vary much, if at all, but the sustained data tranfer rate is heavily dependent on platter density.

For example, two drives of the same capacity and same RPM, but with one having twice as many heads as the other, will have transfer rates that differ by sqrt(2), all other things being equal. It may also be that, even when both drives have the same usable capacity and same number of platters, one will have a higher bit density, and therefore a higher transfer rate.

Here are several threads that illustrate the above:
