Difference between hdd wd2500aaks and wd2500aakx

[Jolyon0]

I want a backup SATA HDD. These appear suitable, but what is the difference between WD2500AAKS and WD2500AAKX?

Is it possible to use an old IDE HDD from another computer as backup? My computer has an Asus M4A88T-M motherboard, and a Seagate 1TB SATA-3G HDD.
If it would work, it is not difficult for me to transfer the old disk. Would it be recognized?

the aaks is sata 3 the aakx is sata 6,the old disk should work but just make shure that the ide is not read as the first drive in the bios mobo.

As long as you don't have two other IDE devices it will be fine. If you use an IDE Optical drive (CD/DVD/Blu-ray) then you might run into a problem with cable length as getting from the Optical drive in your case to that hard drive can be an issue in most cases unless it is installed right below the Optical drive.

Another difference between the drives is that the AAKX is an Advanced Format drive.

Many thanks for both replies. I shall try to install the IDE HDD, as that will do as a backup.
