Storage question

[The Pc BUilder]

What is the difference between: M.2, 2.5, 3.5, nvme storage devices  

 

[Electronics Wizardy]

m.2, 2.5, and 3.5 are all form factors, so the size of the drive.

 

NVMe is a protocol, so how the drive talks over the pcie bus. THis is normally the alternative to AHCI over SATA. 

 

If your getting a new system, id get a nvme m.2 for boot, and then a 3.5 hdd for mass storage if needed.

For hard drives? Go 3.5, bigger, faster, and normally cheaper. Only get a 2.5in drive if your using a compact case or laptop where a 3.5in hdd won't bit.

They're literally just different physical sizes.

 

SSDs are usually 2.5 (if they're not M.2 form factor) though some massive ones are 3.5; hard drives are 3.5 for desktops and 2.5 for laptops and small form factors.

 

As @Electronics Wizardy states, 3.5 usually represents far better value for money on the desktop side.
