For a performance boost I recommend a Crucial M500:
The Solid State Drive costs more per GB than a conventional hard drive but the performance enhancements are worth it.
Crucial also have some recommendations for internal hard drives if you don't want the Solid State Drive.
The only way to mount two, 2.5" drives is to replace the DVD drive with an adapter that takes the non-boot drive (you can install a storage drive that way but you WILL NOT be able to boot the system from a drive mounted in such an adapter).
Some third parties supply dvd bay adapters - www.newmodeus.com
is one of them.
i was looking for a new internal Hard disk for replacement and i came across WD 1 TB Laptop Internal Hard Drive (WD10JPVT/WD10JPVX). In one of the reviews for this product it was written that this is a new 4K format drive and we should check whether BIOS and SATA controller can handle this format.
Can you help me out on how to check the compatibility of this product with my BIOS and SATA controller?
