Frequently asked questions
- Will a Gen4 SSD work in a Gen3 slot?
- Yes, Gen4 drives are backward compatible and run at Gen3 speeds in an older slot. To reach full speed you need a motherboard with a Gen4 M.2 slot.
- Do Gen4 NVMe SSDs need a heatsink?
- Many run fine with the motherboard's built-in M.2 heatsink. Under sustained heavy writes a heatsink helps prevent thermal throttling, so check your board's provision first.
- Is a Gen4 SSD noticeably faster for everyday use?
- For general computing the difference over a good Gen3 drive is modest. Large file transfers and certain creative tasks benefit most from the extra sequential speed.
