Updating firmware hard drive
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.The possible exception to this are the super-small form factor PCs that can only handle a 2.5″ drive.If you’re interested in the M.2 drives, you’ll have to determine whether your PC supports them. As they’ve gotten smaller and sleeker, laptops have also gotten harder to upgrade.
You’ll find them in slightly different configurations.Choosing a drive that fits your budgets and does what you need is the first step.These days, your most important choice is between a traditional hard drive or a solid state drive (SSD).These drives actually look more like a stick of RAM than a hard drive.
Instead of connecting to your motherboard via a SATA cable the way regular drives do, M.2 drives get plugged into a specialized slot.
2.5″ drives are traditionally meant for laptops, but will also fit just fine in a desktop PC.
