what is the difference between sata sata2 and esata?
i was looking at:
http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=2010010001%20117752937&name=SATA%20/%20eSATA
it has those 3 different sata cables. sata, sata2, and esata.
what is the difference between those?
and
i have a compaq presario sr1720nx desktop. which one do i need and how do you know?
thanks.
Hi.
The different SATAs' is because they have different transfer speeds.
SATA I supports 1.5 GB/s transfer
SATA II supports 3.0 GB/s transfer
GB/s means GigaBITS per second, not bytes
eSATA is external SATA, which has a lower rate of 300MB/s
MB/s means MegaBITs per second, not bytes.
According to your compaq presario sr1720nx PC, you'll need a SATA I Cable (1.5 GB/s cable). Remember SATA Cables are only for internal hard drives. (eSATA ) is for external HDs, printers, cameras, much like an USB port.
Hope that Helps.
