Capacity and interface

The Samsung 990 EVO Plus is a 1TB internal solid state drive in the M.2 2280 form factor. It connects via PCIe 4.0 x4 or PCIe 5.0 x2 and uses the NVMe 2.0 protocol. The drive is designed for consumer PCs and laptops that need fast storage in a compact slot.

Who this suits

This SSD suits users upgrading a laptop or desktop with an M.2 slot that supports PCIe 4.0 or 5.0. Its HMB design means no DRAM cache, so systems without HMB support in the BIOS may not see full performance. Buyers needing hardware DRAM or a different capacity should consider other models.

Installation and common issues

Installation is a standard M.2 screw-in process; the drive draws up to 4.3W active read and 4.2W active write. Most issues arise when the motherboard BIOS lacks NVMe 2.0 or HMB support, or when the slot shares bandwidth with other devices and drops to lower speeds. Samsung Magician software helps keep firmware current.

Spørgsmål om denne vare

What motherboard slot and PCIe generation do I need for the 990 EVO Plus to run at its 7150 MBps read speed?

An M.2 2280 slot wired for PCIe 4.0 x4 or PCIe 5.0 x2 will deliver the rated 7150 MBps sequential read and 6300 MBps write.

Will the drive work in my older laptop that only supports PCIe 3.0 x4?

Yes, it is backward compatible with PCIe 3.0 x4 slots, but sequential speeds will be limited to the 3.0 x4 ceiling rather than the rated 7150 MBps.

How can I verify the 990 EVO Plus is healthy and performing at its 850000 IOPS random-read rating after installation?

Run Samsung Magician software; it reports drive health, firmware version, and lets you benchmark random-read IOPS against the 850000 IOPS spec.
