Responsive client storage with a flexible PCIe interface
The Samsung 990 EVO Plus 2TB MZ-V9S2T0BW combines Samsung V-NAND TLC, an in-house controller and Host Memory Buffer architecture for supported client PCs. Its dual-interface design can operate through PCIe 4.0 x4 or PCIe 5.0 x2, while Intelligent TurboWrite supports the published write-performance profile under Samsung's stated conditions.
Dual PCIe interface
Samsung specifies PCIe 4.0 x4 or PCIe 5.0 x2 with NVMe 2.0, giving the drive flexibility across compatible M.2 platforms.
Up to 7,250MB/s read
This exact 2TB model is rated for sequential reads up to 7,250MB/s.
Up to 6,300MB/s write
Sequential write performance reaches up to 6,300MB/s with Intelligent TurboWrite active under the stated test conditions.
1,000K IOPS/1,350K IOPS
Capacity-specific random performance is rated up to 1,000K IOPS read and 1,350K IOPS write IOPS.
HMB cache architecture
Host Memory Buffer uses supported system memory rather than a dedicated DRAM cache on the drive.
Security and warranty
AES 256-bit, TCG Opal 2.0 and IEEE1667 support accompany a five-year limited or 1,200TBW warranty, whichever comes first.
Who is the Samsung 990 EVO Plus 2TB MZ-V9S2T0BW best for?
A strong choice for
- Compatible client PCs with an M.2 2280 PCIe slot
- Gaming and everyday performance upgrades
- Creative work and large-file transfers
- Systems supporting PCIe 4.0 x4 or PCIe 5.0 x2
- 2TB buyers seeking a Samsung consumer NVMe drive
Consider another model if you need
- Your system lacks a compatible M.2 2280 PCIe slot
- You require an integrated heatsink
- Your platform cannot provide sufficient airflow or cooling
- You require endurance above 1,200TBW
- You need an enterprise or data-centre SSD
