Samsung 990 EVO Plus 2 TB (MZ-V9S2T0B/AM)
2 TB M.2 2280 NVMe 2.0 drive supporting PCIe 4.0 x4 or PCIe 5.0 x2. The Plus revision is distinct from both the 990 EVO and the separately listed 990 PRO. Performance values are manufacturer-rated maxima, not independent test results.
IDENTIFICATION: Verify the complete MPN, regional suffix, serial/date code and firmware from the drive label. Capacity variants, hardware revisions and cooling bundles can differ; the specifications below are for 990 EVO Plus 2 TB where the cited manufacturer documentation identifies them.
Manufacturer-identified specifications
| Product / MPN | Samsung 990 EVO Plus 2 TB (MZ-V9S2T0B/AM); manufacturer code MZ-V9S2T0B/AM. |
|---|---|
| Capacity / form factor | 2 TB; M.2 2280 (22 × 80 mm), single module. Confirm sidedness and surrounding component clearance from the exact revision. |
| Interface / lane width | PCIe 4.0 x4 NVMe; link speed is host-negotiated and can be lower on older hardware. PCIe 5.0 x2 is also a supported link mode for this hybrid-interface model. |
| Protocol / flash | NVMe over PCI Express; manufacturer identifies this product as a client M.2 SSD. Use the exact product document for protocol revision, NAND and any DRAM/HMB details. |
| Rated sequential performance | up to 7,250 MB/s read and 6,300 MB/s write. Ratings depend on capacity, firmware, workload and the test conditions published by the manufacturer. |
| Endurance / warranty | 1,200 TBW; five-year limited warranty (whichever occurs first, subject to Samsung terms) |
| Model generation / thermal package | 2024 product generation. MZ-V9S2T0B/AM; bare M.2 2280 module. Regional suffixes and firmware revisions should be checked on the label. |
Compatibility, installation & service
- This model can negotiate a PCIe 4.0 x4 or PCIe 5.0 x2 connection. Verify host lane allocation, M.2 2280 clearance, boot firmware support and the link generation used by the selected socket. The quoted product maximum is vendor-rated; sustained performance depends on workload, cooling and the actual negotiated link.
- Read the motherboard or laptop service manual to check socket keying, supported protocol, PCIe generation/lane count, shared SATA/PCIe lanes, BIOS boot support, standoff position, module sidedness and cover clearance. M.2 is a form factor, not proof that a socket supports NVMe.
- Back up data and retain recovery media and encryption keys before replacement or firmware service. Use only the manufacturer utility/firmware intended for the exact model and capacity; confirm power and system stability during updates.
- Follow the host’s service procedure, shut down and disconnect standby power when instructed, and use electrostatic-discharge precautions. Do not hot-plug a client M.2 SSD unless the platform manual explicitly supports it.
- Monitor SMART health and temperature during sustained transfers. High burst benchmarks do not predict sustained writes, thermals, or service life; keep independent backups regardless of the TBW rating.
