DISK TYPES Although we seemed to have reached a low point in computer prices with many systems appearing to show increases the price of very large hard disk drives is still falling. This is good news for many of you who will need more storage space for all of your digital photographs taken over the holidays but you do need to be careful about the type of connector. For over 20 years disk drives, along with CD and DVD devices, used a type of connection called ATA – you may have seem the ‘ribbon’ cable connection used to plug into the computer motherboard. These have now been superseded by the SATA connector which arrived about 4 or 5 years ago. It’s a much thinner cable and manufacturers claim the data transfer rates are higher. Unfortunately the two are not interchangeable and the original ATA devices are becoming harder to source which is keeping the price of relatively small disks high when compared to much larger SATA disks. Of course all this is only a problem if you want to install or replace a disc inside your computer but this is still the best place for important data to reside.
