External Hard Drives
With today’s wide variety of storage devices comes lots of confusion about what types of drives to use for what data types. Adding to the confusion is Serial ATA (SATA) and SAS, which refer to disk drive interfaces, and Solid State Drive (SSD) which refers to a particular kind of internal technology. Then there are considerations of random access performance, sequential performance, cost, density and reliability. All these factors make selecting the right drive, a challenge.
