Form factor and capacity

The Samsung 850 EVO is a 1 TB internal solid-state drive built in the M.2 2280 form factor. It connects through a SATA interface and uses TLC memory components. This drive suits notebooks and small-form-factor desktops that need a compact storage upgrade.

Sustained workload behaviour

Under continuous write loads the drive maintains steady throughput thanks to its SATA 6 Gb/s link and TLC architecture. Thermal output stays low because the controller is designed for thin enclosures without active cooling. Performance remains consistent during large file transfers or extended application caching.

Upgrade path and value

The 850 EVO replaces 2.5-inch SATA SSDs or mechanical hard drives in systems with an M.2 slot wired for SATA. The jump is worthwhile when physical space is limited or when a lighter 3.0000 gram drive improves portability. Users gain the same SATA speed envelope in a smaller package.

Questions about this item

How much power does the 850 EVO draw during long write sessions?

The SATA interface limits peak power to the standard 5 V rail, so sustained writes stay within typical notebook thermal envelopes without extra cooling.

Does my motherboard need an M.2 slot wired for SATA rather than PCIe?

Yes — the drive uses the SATA protocol through the M.2 2280 connector, so the slot must support SATA signalling; a PCIe-only slot will not recognise it.

Can I keep my old 2.5-inch SATA drive alongside this M.2 2280 unit?

Both drives speak SATA, so the operating system will see them as separate volumes and you can use the older drive for bulk storage while the 850 EVO handles the OS.
