Storage Drives

2.5" SATA3 Hard Disk Drives

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 up to 3TB. 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 drive here use the latest SATA III 6Gbps interface, faster spinning drives will read and write data faster.

2.5" SATA3 SSDs

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 PCIe NVMe SSDs

This the Next Generation Form Factor (NGFF) or M.2 as its now called M.2 replaced the older mSATA standard, The M.2 SSD Connects to your device via a M.2 Socket via either PCI Express using AHCI (Advanced Host Controller Interface) which was the standard for older legacy operating systems, And the newer PCI Express using 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.
