Which SSD for HP Probook 4540s?

[mohrd]

Which spec should I check before choosing SSD for my Probook 4540s?
I want to replace ODD with SSD. And I don't know what is the connection standard (SATA 3.0 or SATA 6.0. Does it matter?)

Hey there, mohrd.

Actually SATA revision 3.0, 6 Gbit/s, 600 MB/s, SATA III are all one and the same thing. If you want to learn more about the different revisions (versions) of SATA, you can check out this link: https://en.wikipedia.org/wiki/Serial_ATA. You should definitely go for a SATA III SSD. I assume that your motherboard has SATA III ports, but even if it doesn't, the SATA interface is backwards compatible and you should have no trouble using a SATA III drive with a SATA II port. Note that this would bottleneck the performance of the drive as SATA II has speeds of up to 300MB/s and SATA III has speeds of up to 600MB/s.
As for the SSD's height, probably a 9.5mm would fit, but that depends on the SSD caddy you're going to get in order to replace the OD.

Hope that helps. Please let me know if you have any questions whatsoever.
