1.5TB to 5TB 2.5" SATA3 SSDs

Available in 1.9TB, 2TB, 4TB and 5TB capacities these SATA III 6Gb/s SSDs may no longer be the fastest around thanks to emerging PCIe SSDs, but they're the most cost-effective and are still easily fast enough for most users. You'll need a spare SATA 6Gb/s port to get the most from them, and a 2.5" capable drive bay - an adaptor may need to be bought, but most cases have at least one. These drives are the highest capacity ones available, suitable for holding an operating system, as well as numerous programs and a healthy collection of media and games.

Direct Attached Storage / Enclosures

Direct Attached Storage or DAS is an external storage device that is connected directly to a server or workstation without a network device in between (ie there is no hub, switch or router required) using USB, Firewire or eSATA for example. This direct connection ensures fast access to data. A DAS will work as though the hard drives are internally connected, meaning drives can be partitioned, formatted and set up like any other internal hard drive or raid array. These DAS devices are available for standalone desk or rack mounting.

EOL - SATA II - 40GB - 200GB

TThese 3.5" hard drives utilise the SATA II 3Gb/s interface, making them ideal for a range of applications including desktops, workstations and servers. Their high capacity aswell as the fast access speeds on offer, make these range of drives the ideal choice for todays systems. Some hard drives include NCQ (Native Command Queuing), which allows the drive to internally optimise the order in which received read and write commands are executed. Note that the SATA II range of hard drives are backward compatible with SATA I motherboards.
