My aging Acer Aspire with SATA II 5400 rpm drive is ready for a drive replacement. The two most logical options are :
(1) 7200 rpm WD Scorpio Black HD (about one-half cost of equivalent SSD).
The WD Scorpio is "safest" choice for trouble-free operation. However the title contains "SATA 300" which may or may not be cause for concern. If SATA 300 means 300 Gb transfer rate i assume that is compatible with current SATA II interface. If not can this drive be successfully installed in the Acer without upgrading an adapter ?
Is there any compelling reason to consider an SSD replacement instead of HD ? Thanx.
First of all SATA is backwards compatible which means a SATA 2 drive can work in a SATA 3 port and vice versa. The only difference being that the port will limit the speed of the connection.
For example a SATA 3 drive on a SATA 2 port will run slower.
There are a number of different benefits that an SSD provides over a standard hard drive. They are faster, much faster than a hard drive and can be up to 21x faster. They have no moving parts which means they are more sturdy than standard hard drives.
