Cheaper, bulkier laptops, and few business-class designs like Lenovo’s ThinkPads or Dell’s Latitudes, still allow access fairly easily. Most laptops that aren’t super-tiny still use 2.5″ drives, but they may or may not have a user-accessible drive bay for upgrades. As they’ve gotten smaller and sleeker, laptops have also gotten harder to upgrade. Some laptops, like Macbooks, use an M.2 storage drive that requires advanced, model-specific instructions for replacement.

If you’re interested in the M.2 drives, you’ll have to determine whether your PC supports them. Instead of connecting to your motherboard via a SATA cable the way regular drives do, M.2 drives get plugged into a specialized slot. These drives actually look more like a stick of RAM than a hard drive.

That’s what size you’ll use whether you’re mounting it in a desktop or laptop. Note that these are usually labelled as “SSD mounting brackets.” This is because all SSDs in the traditional hard drive form are 2.5″ drives.

If yours doesn’t, you’ll need a mounting bracket like this one. Some desktop PCs have built in mounting points for 2.5″ drives. The possible exception to this are the super-small form factor PCs that can only handle a 2.5″ drive.Ģ.5″ drives are traditionally meant for laptops, but will also fit just fine in a desktop PC. The 3.5″ drives are also known as “full size” or “desktop drives.” Pretty much every desktop PC out there has room for at least one (and sometimes many) 3.5″ drives. Hard drives typically come in two sizes: 2.5″ and 3.5″.
