Available in 120, 128, 240, 250, 256, 275 and 480GB 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 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, 256, 480, 500 and 512GB 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 utilise 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.

M.2 replaced the older mSATA standard. Available in 960GB, 1TB, 2TB, 4TB & 8TB 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.

Intended mainly for data centres, these SSDs are as good as it gets for high-speed storage. Using fast PCIe 3.0 lanes and the new Non-Volatile Memory Express (NVMe) interface, which is designed specifically to take advantage of SSDs, these drives smash through previous SATA limitations with throughput of 2GB/s or more in some cases and high sustained performance too. The 2.5” models here use the new SFF-8639 connection, sometimes called Express Bay, which means they can be hot-swapped.

M.2 SSDs are compact small form drives that connect directly to a slot on the motherboard. Their small dimensions makes them an ideal choice for a boot drive, leaving the 2.5in or 3.5in bays on the front of your server free for bulk storage drives.

SD memory cards expand the file storage of electronic devices such as video cameras, digital stills cameras, mp3 music players & even some computer systems with a SD slot.

These particular SD cards are rated up to UHS-I Class 1 (U1), meaning they can write at up to 10MB/sec making them suitable for recording up to FullHD (1080p) video and high resolution photos.
