Our take on the Samsung 990 EVO Plus 4TB PCI-E 4.0 x4 NVMe M.2 2280 SSD

The 990 EVO Plus is Samsung's mainstream NVMe M.2 2280 drive, here in a 4TB capacity. It runs PCIe 4.0 x4 or PCIe 5.0 x2, so it fits both older and newer laptops and desktops without wasting lanes. Samsung rates it at 7,150 MB/s sequential read and 6,300 MB/s write with 1,050K/1,400K random IOPS, using TLC V-NAND. It sits below the flagship 990 Pro on sustained speed but offers far more capacity per drive than most rivals at this tier, and it includes hardware AES 256 encryption with TCG/Opal and eDrive support.

Pros
  • 4TB in a single M.2 2280 drive
  • Works on PCIe 4.0 x4 and PCIe 5.0 x2
  • Fast rated sequential and random speeds
  • TLC NAND rather than QLC
  • Hardware AES 256 encryption with Opal and eDrive
  • Low active power draw of about 5.5W
Cons
  • Sustained writes fall short of the 990 Pro
  • No DRAM cache on the EVO line
  • Runs at x2 on PCIe 5.0, so no Gen5 speed gain
  • Peak speed needs a free PCIe 4.0 x4 slot

What reviewers say

Owners of the 990 EVO line generally report it hits close to its rated speeds in everyday use and stays cool in laptops. The common complaint is that large sustained writes slow down compared with Samsung's Pro drives.

What people mention
  • SpeedPraisedOwners say sequential and random performance meets the rated figures in normal use.
  • Sustained writesCriticisedLong continuous writes slow down compared with Samsung's Pro drives.
  • Heat and powerPraisedUsers report it runs cool and sips power, which suits laptops.
  • ValueMixedBuyers like the 4TB capacity but note it costs more than QLC rivals.
  • SetupPraisedInstallation and Samsung Magician software are described as straightforward.

About the Samsung 990 EVO Plus 4TB PCI-E 4.0 x4 NVMe M.2 2280 SSD

The Samsung 990 EVO Plus is a 4 TB NVMe solid-state drive in the M.2 2280 form factor. It uses Samsung V-NAND TLC memory and connects over PCIe Gen 4.0 x4 or PCIe 5.0 x2 (NVMe 2.0).

It reads sequentially at up to 7,150 MB/s and writes at up to 6,300 MB/s. Random performance at 4KB, QD32 reaches up to 1,050K IOPS for reads and 1,400K IOPS for writes.

The drive supports AES 256 encryption (Class 0), TCG/Opal v2.0 and MS eDrive (IEEE1667).

Questions and answers

Does the 990 EVO Plus work in a PCIe 4.0 slot?
Yes. It runs at PCIe 4.0 x4, which is its fastest mode. It also works in a PCIe 5.0 slot at x2.
Is it fast enough for a PS5?
Yes. Its rated read speed is well above what the PS5 requires, and it is a standard M.2 2280 drive.
How does it compare with the 990 Pro?
The 990 Pro is faster on sustained writes and has a DRAM cache. The 990 EVO Plus is cheaper per terabyte and runs cooler.
Does it have hardware encryption?
Yes. It supports AES 256 with TCG/Opal v2.0 and MS eDrive, so you can use BitLocker or similar without a performance hit.
What NAND does it use?
Samsung V-NAND TLC, not QLC, which helps it hold speed better than budget drives.
What is in the box?
The drive itself. There is no heatsink, so a desktop or PS5 install may need one.
