Samsung 990 PRO 2TB NVMe M.2 2280 SSD, PCIe 4.0 x4, 7450/6900 MB/s, 2GB DRAM, 1200 TBW (MZ-V9P2T0BW)

⭐ At 2 TB the 990 PRO is a better drive than at 1 TB, and not only because it is bigger. Three published figures improve with capacity:
• Endurance doubles: 1,200 TBW against 600 TBW at 1 TB.
• DRAM doubles: 2 GB of LPDDR4 against 1 GB.
• Random read rises: 1,400,000 IOPS at QD32, against 1,200,000 at 1 TB.
Sequential speeds are the same at both capacities. So if you are choosing between two 1 TB drives and one 2 TB, the 2 TB is the better engineering as well as the tidier setup.

⭐ Why the PRO rather than the 990 EVO Plus? DRAM. The PRO has 2 GB of its own LPDDR4 at this capacity; the EVO Plus is DRAM-less and borrows system memory. Peak speeds are close enough to ignore. What DRAM buys you is consistency: under sustained writing, heavy random access, or once the drive is nearly full, a DRAM drive holds performance where an HMB drive sags. Buy the PRO for consistency, not for peak.

⚠️ This is the bare drive — and the heatsink version has two part numbers at 2 TB as well. Samsung sells the 2 TB heatsink drive as MZ-V9P2T0CW (its German site) and MZ-V9P2T0GW (its UK site), with no published difference between them. If you want the heatsink, either is the same product.

⚠️ PlayStation 5. Samsung makes its PS5 statement only for the heatsink version: “The thin body is compatible with PlayStation® 5, desktops, and laptops meeting the PCI-SIG® D8 standard”, with the note that the D8 limit is 8.8 mm. Samsung makes no PS5 claim for this bare part number, and the console requires a heatsink this box does not contain — nor a mounting screw. For a PS5, buy the CW or GW version.

ℹ️ Controller name is not published. Samsung says only “Samsung in-house Controller” on the datasheet and every regional page. The codename that circulates in reviews is not a Samsung specification and we do not print it.

⚠️ Availability. Samsung UK shows the 2 TB as no longer available and Samsung Germany as “nicht verkäuflich”. The 9100 PRO has taken over as flagship. Treat this as channel stock — on a PCIe 4.0 board it remains exactly the right drive.

✓ A gaming or workstation PC with a PCIe 4.0 M.2 slot

✓ Sustained heavy writing — video, virtual machines, large datasets

✓ Anyone choosing between two 1 TB drives and one 2 TB — take the 2 TB

✓ A build where the motherboard already provides an M.2 heatsink

2 TB is the capacity at which the 990 PRO makes the most sense, and the reason is not just the space. Samsung doubles both the DRAM and the endurance at this capacity — 2 GB of LPDDR4 and 1,200 TBW against 1 GB and 600 TBW — and raises random read to 1,400,000 IOPS. Two 1 TB drives would give you the same total space with half the endurance headroom each and an extra M.2 slot occupied. Against the cheaper 990 EVO Plus, what you are buying is real onboard DRAM instead of borrowed system memory, which shows up as consistency under sustained load rather than as a higher peak number. Two practical notes. This is the bare drive, so check whether your motherboard already covers the M.2 slot — if it does, this is the right part; if it does not, or the drive is for a PlayStation 5, buy the heatsink version, which Samsung sells at 2 TB under both CW and GW codes with no published difference. And on a PCIe 4.0 board a Gen 5 drive would gain you nothing, so the 990 PRO is still exactly right there. Browse our internal SSD range.
