Samsung 850 EVO 120GB M.2 SATA SSD

The Samsung 850 EVO MZ-N5E120BW is a 120GB internal solid-state drive built on 3D NAND technology. It uses the M.2 2280 form factor and connects through a SATA III interface. Sequential reads reach up to 540 MBps and writes up to 500 MBps. Random 4KB performance hits 97,000 IOPS read and 89,000 IOPS write.

Suits SATA M.2 slots only

This drive fits laptops and desktops with an M.2 slot wired for SATA signalling. It will not operate in slots that only accept PCIe signalling. The 2.30mm height matches standard single-sided M.2 clearance. Buyers needing higher capacity or PCIe speeds should consider other models.

Interface decides compatibility

The defining specification is the SATA III interface combined with the M.2 2280 form factor. Verify that the host system's M.2 slot supports SATA before purchase. The MGX controller and 3D NAND deliver the quoted speeds within that SATA link.

商品問答

Will the 120 GB 3D NAND drive slow down once its SLC cache fills during a long write?

The MGX controller manages 3D NAND directly; sustained writes run at up to 500 MBps once the cache is exhausted.

How warm does the M.2 2280 module get and does it need extra cooling during all-day use?

The 2.30 mm thick board draws little power; typical laptop airflow keeps it within normal operating temperature without a heatsink.

My laptop has an M.2 slot — what must it provide for this SATA III drive to work?

The slot must support SATA signalling and accept a 22 mm wide, 80 mm long module.
