I am sensing that my HP Pavillion tx1000 notebook's 250GB SATA drive's days are numbered
and I have been trying to find a new one to replace it with. However, this 5400 RPM
Western Digital WD2500BEVS-60UST0 model doesn't seem to be available at a reasonable price
and most that pop up in Google search are used. So I was wondering if perhaps I could look
for other 2.5" SATA models, maybe with higher capacity and higher speed, but I am worried
what kind of compatibility problems I could face then. Even if the electrical interface is
the same, they might not fit into the caddy the original drive is in. What about SATA II
or SATA III upgrades? Has any of you done this kind of laptop HD replacement and could
give me some pointers? Thanks.

250g on amazon is $28 plus shipping.
Put the new hdd in your external backup enclosure, clone your current
drive to the backup. Remove cloned hdd and install in LT.
