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.

M.2 replaced the older mSATA standard. Available in 120, 128, 240, 250 and 256GB sizes the M.2 SSD Connects to your device via an M.2 Socket using the newer PCI Express NVMe (Non-Volatile Memory Express) controller variant designed to fully utilize the capability of high-speed PCI Express storage devices to perform many I/O (in/out) operations in parallel. These SSD's can achieve Read speeds in Excess of 3000MB/s and Write speeds over 2000MB/s making them the fastest available.

While the M.2 connector can be used for PCIe SSDs, the ones here are SATA 6Gb/s only, so the benefits over standard 2.5" SATA drives are to do with space-saving, not speed. Available in 120, 128, 240, 250, and 256GB sizes they're perfect for small form factor systems and laptops, but make sure your M.2 slot works with SATA devices, and that it supports the SSD's size, both in length (2280 means 80mm long) and thickness.

These 3.5" hard drives are available in 2TB, 3TB, and 4TB sizes. They utilise the newer SATA III 6Gb/s interface, ensuring as high speeds as possible with their mechanical technology, especially when using them in RAID. They're the most popular drives for today's desktop PCs, thanks to high spindle speeds, lots of cache and huge capacities.

2.5" drives are significantly smaller than standard 3.5" ones, making them great candidates for upgrading the storage of your laptop or games console, especially as they're available in capacities of 2TB, 3TB, 4TB and 5TB. Remember to check the height of the drives, as most portable or console systems only have bays which support 9.5mm drives or less. Also pay attention to the spin speed in rpm; while all drives here use the latest SATA III 6Gbps interface, faster spinning drives will read and write data faster.

These 3.5” hard drives utilise the SATA III 6Gb/s interface and have been specially designed for write intensive applications such as CCTV recording systems that are active 24 hours a day.

MicroSD memory cards expand the file storage of mobile devices such as cameras and phones and other devices with a MicroSD slot.

These particular MicroSD cards are rated as up to UHS-I Class 3 (U3), meaning they can write at up to 30MB/sec making them suitable for recording 4K or FullHD (1080p) video at 60 - 120fps and high resolution photos. Some of these cards are also rated as V30 Video Speed, labelling them as being optimised for video recording.

Some cards even feature an Application Performance Class, making them ideal for use with devices such as tablets & smartphones. Cards labelled A1 provide a minimum of 1.5k Read & 0.5k Write IOPS, while A2 labelled cards push random performance even further with a minimum of 4k Read & 2k Write IOPS.

These NAS units are sold with hard disks bundled, saving you the trouble of buying them yourself. They come in a range of sizes and capacities, from single bay 2TB units suitable for modest personal users all the way to large, multi-bay units with 16TB, 24TB or even 32TB of storage on tap.

Some of these NAS boxes do not come pre-configured, giving you the chance to set them up as you see fit, including what RAID level you want to use, if any.

The NAS solutions with the purple 'SYSTEM' flag are built by our award-winning 3XS Systems engineers and come pre-configured with your choice of RAID, so all you have to do is connect them to your network.

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.

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.

These external drives use mobile 2.5in hard disks, which mean they're a lot more portable than desktop drives. They've got capacities that range from 250GB to 4TB, most use super-fast USB 3.0 and Thunderbolt connections, and many include backup applications and cloud storage deals for added security.

These larger drives use desktop-style 3.5in hard disks, which means they're better suited to sitting on a desk than being carried around in a bag, but their larger profile does mean big capacities: some of these products serve up a whopping 4TB of space. Their 7,200rpm spindle speeds mean file transfer are quicker than 2.5in drives, too.

External SSDs are ideal for users looking for lightweight, portable and speedy storage. Their pocket-friendly enclosures are significantly smaller and lighter than external hard drives, and with no moving parts they're also silent, more robust and less prone to physical shock damage. They use the USB 3 interface, which is 10 times faster than and backwards compatible with USB 2.
