WD2001FASS and WD2002FAEX Comparison

[gx240]

I'm looking at two different Western Digital internal hard drives, WD2002FAEX and WD2001FASS.

As far as I can tell from the specifications pages, they're identical, except that the WD2002FAEX is 6 Gb/s SATA, and the WD2001FASS is 3 Gb/s SATA. But for some reason they're the same price everywhere I look. Here's the Newegg links for example:

WD2002FAEX

WD2001FASS

Why would they be the same price if one drive has a newer, faster connection than the other? Am I missing something?

Market prices are influenced by economic supply and demand,
not simply by specifications.

WD's website has a full set of specifications: www.wdc.com

If you check around the Internet, I expect you will see
a variety of different asking prices.

The faster connection itself makes no difference to the performance of a hard drive because even the slower connection is much, much faster than the data coming off the platters. It's like a bicycle on a road - the cyclist isn't going to get there any faster whether the speed limit is 60km/H or 120km/H.

Since there's no performance benefit to the drive with the faster connection, there's no reason that you should expect to pay more for it.

Only SSDs make full use of SATA 3 and only a few of those benefit from SATA 6 . Mechanical drives just are not fast enough to come close to using SATA 3 much less SATA 6.
