Buy HDDs and SSDs at Mwave!

A hard disk drive (HDD) or solid-state drive (SSD) is the storage device for your PC. Your operating system, programs and files are all stored on this device. In recent years, SSDs have become popular due to their fast read and write speeds, compact form-factors and high durability. SSDs are prevalent in notebooks, tablets, high-performance PCs, small form-factors desktops and all-in-ones (AIOs). We stock both HDDs and SSDs and each are available in internal and external versions.


Types of HDD and SSD interfaces

  • SATA: the most common type of internal HDD connection. This provides a data connection between your HDD (or 2.5” SSD) and motherboard. SATA HDDs and SSDs are available in 3.5” (desktop), 2.5” (some laptops and desktops) and M.2 form-factors.
  • M.2: common on modern motherboards and most laptops and tablets and works with only M.2 form-factor SSDs. M.2 comes in both SATA and NVMe (latter requiring PCIe lanes) variants along with different lengths so be sure that you are buying an M.2 SSD that is compatible with your computer.
  • PCIe: a super fast type of drive that connects over PCIe and can be used in any PC which supports storage over PCIe. PCIe-M.2 adapters can also be purchased to provide support for M.2 form-factor PCIe SSDs. 
  • U.2: typically a rare connection on consumer grade motherboards but somewhat common on server grade hardware and can be used to connect SAS drives and ultra-high performance SSDs.
  • USB, USB-C and Thunderbolt: USB is the most common external HDD and SSD connection type with USB-C 3.1 and Thunderbolt providing the highest speeds - just be sure that both your PC and external drive can actually take advantage of the extra transfer speed.


HDDs can be found in larger capacities than SSDs and are also more cost-efficient per $. HDDs can be found in capacities of up to 18TB while SSDs max out at 8TB (and cost 3-4 times more than a 12TB HDD). Typically, it is advised to at least have an SSD for installing your OS and popular programs and games and then using a cost-efficient HDD for all other files.
