Question issues replacing stock hd in laptop?

[d_112359]

my laptop's internal drive is failing, and i'm considering replacing it w/another one that's not quite the same. could anyone here tell me if i'll be looking at compatibility issues ?

current drive :

• 1tb sshd
• 5400rpm 6gb/s sata+ncq
• power draw 2.7w seek, 0.9w idle, startup = ?

target drive :

• 500gb hd
• 7200rpm 6gb/s sata [no ncq]
• power draw 1.8w seek, 0.65w idle, startup = 1.0amps

so it looks like the replacement drive would actually require less power even though it's a mechanical drive and not a hybrid ssd. should i be concerned about the lack of native queuing ?

both drives are about the same size [the replacement drive is a little thinner].

so - am i good, or asking for trouble ?
are there other characteristics i should be looking at too ?

thanks.

The lack of NCQ will slow things up a tiny bit, nothing major.
