Yes, note, 320GB, 5,400 rpm. The discussion was about 320GB, 7,200 rpm.

I am afraid you misunderstood (the article is badly written). Toshiba
announced 2 drives:
- MK3252GSX, which is a 320GB HDD at 5400rpm
- MK2049GSY, which is a 200GB HDD at 7200rpm
So no 320GB 7200 rpm drive yet :-(

Please log in for more thread options Just thought I'd chime in... check the laptop you're looking at to see
if it uses an externally-accessible drive carrier. These used to be
common, particularly on corporate-market models, where most home/
retail models have the hard-drive internalized. If yours uses a drive
carrier, swapping drives is simple and relatively easy--usually a
jeweler's screw-driver is the only tool needed.
Most 2.5" drives still have 12.5 ms access time, whether 5400 rpm or
7200 rpm. The 7200 rpm drive may have a faster transfer speed. If
you want 2.5" performance, you have to go with Seagate's corporate
(blade-server market) 10,000 rpm drives, available as of December 2004
in 36 GB and 73 GB versions as U320 SCSI -- but I've heard they've
since been adapted to SATA-II/300. They have 4.9 and 4.5 ms access
time and transfer speed unequaled among mechanical 2.5 inch drives,
last I heard. Of course, there are the solid-state hard-
drives...bring money!
If you can find an express-card eSATA-II/300 card, that would give
optimal access to an external hard drive, to take full advantage of a
big (cheap) fast hard-drive. Otherwise, eSATA-150 PC-card/PCMCIA
cards are pretty cheap and realistically almost as good. eSATA-II
offers hot-swap, which is definitely a good. Speed ranking, eSATA-II,
eSATA, Firewire 800, Firewire 400/iLink400, USB 2.0; but that depends
on the interface to the controller (i.e., on-motherboard, express-
card, PC-card).

How to check that?

What does it mena external versus internal? Do these terms refer to
the same thing as in desktop system?

In a thinkpad, wouldn't they use ibm hard drive?

Can you give me some *technical* explanation on express card and on
SATA-II/300, eSATA-II/150 and eSATA-II/300 or refers me to a link to
understand all this in more detail?
