Samsung 990 EVO Plus 1TB NVMe SSD
1TBPCIe Gen5 x2 / Gen4 x4Up to 7250MB/sM.2 2280
The Samsung 990 EVO Plus 1TB, part number MZ-V9S1T0BW, is an internal M.2 2280 NVMe solid state drive with reads up to 7,250MB/s and a flexible dual interface that runs in either PCIe Gen4 x4 or PCIe Gen5 x2 slots, making it a versatile high-speed upgrade for both desktops and modern laptops. It uses Samsung V-NAND TLC flash with hardware encryption for fast, secure everyday and gaming performance.
With sequential reads up to 7,250MB/s, writes up to 6,300MB/s and random performance up to 850K/1,350K IOPS, the 990 EVO Plus delivers flagship-class Gen4 speed with markedly better power efficiency than the previous Generation. Carrying EAN 8806095575674 and MPN MZ-V9S1T0BW, it supports AES 256-bit hardware encryption and a 5-year limited warranty. Typically in stock with fast delivery across Cyprus.
Compatibility note
The 990 EVO Plus is a versatile M.2 2280 NVMe drive with a dual interface: it works in standard PCIe Gen4 x4 slots and also in newer PCIe Gen5 x2 slots, reaching up to 7,250MB/s in either. It is backward compatible with Gen3 at reduced speed and will not work in SATA-only M.2 slots. It ships without a heatsink, so it suits laptops and desktops; for a PlayStation 5 you should add a compatible M.2 heatsink separately.
Best For
✓ Fast gaming laptops and desktops
✓ Systems with Gen4 x4 or Gen5 x2 M.2 slots

Frequently Asked Questions
Will the Samsung 990 EVO Plus work in my laptop or desktop?
Yes, if your device has an M.2 2280 NVMe slot. Its flexible dual interface runs in both PCIe Gen4 x4 and PCIe Gen5 x2 slots at up to 7,250MB/s, and it is backward compatible with Gen3 at reduced speed. It does not fit SATA-only M.2 slots.
What does the dual PCIe Gen5 x2 / Gen4 x4 interface mean?
It means the drive can use two PCIe Gen5 lanes or four PCIe Gen4 lanes, reaching the same up-to-7,250MB/s either way. This makes it compatible with a wider range of motherboards and laptops, including newer systems that offer Gen5 in a x2 configuration.
What is the difference between the 990 EVO Plus and the 990 PRO?
The 990 PRO is a DRAM-equipped flagship with higher sustained performance, while the 990 EVO Plus is a more efficient, value-focused drive with the flexible dual interface. Both reach high speeds; the EVO Plus prioritises efficiency and compatibility, the PRO peak performance.
What do I need to know before buying the 990 EVO Plus 1TB?
Confirm you have an M.2 2280 NVMe slot (Gen4 x4 or Gen5 x2) and a way to clone or reinstall your operating system. It is rated for 600TBW with a 5-year warranty, supports AES-256 hardware encryption, and ships without a heatsink (add one for aPS5).
Singular Expert Insight
The 990 EVO Plus is Samsung’s clever middle-ground drive: it delivers flagship-class 7,250MB/s speeds with much better efficiency than the old 970 EVO Plus, and its dual Gen4 x4 / Gen5 x2 interface makes it unusually flexible across modern desktops and laptops. For most gamers and creators it is the sweet spot, leaving the DRAM-equipped 990 PRO for those who need the highest sustained performance, and value drives like the Kingston NV3 for tighter budgets. As it has no heatsink, add one if you intend to use it in aPS5. Compare tiers and capacities across our

Buyer's Guide
Buy it if
You want fast, efficient 7,250MB/s NVMe storage with a flexible Gen4 x4 / Gen5 x2 interface and hardware encryption for a gaming laptop or desktop, with 1TB of space.
Skip it if
You need the highest sustained performance (choose the DRAM-equipped 990 PRO), a pre-fittedPS5 heatsink, or you only have a SATA slot.
Also consider
990 EVO Plus 2TB for more space, Samsung 990 PRO for a DRAM flagship, or the Kingston NV3 for a budget Gen4 drive.
