Compare Corsair MP700 PRO XT 2TB and Samsung 990 EVO Plus 2TB: prices, speeds, $/TB. Which to buy in May 2026? Full spec breakdown.
Both the Corsair MP700 PRO XT 2TB and Samsung 990 EVO Plus 2TB sit in the Gen 5 category at 2 TB, so the matchup turns on controller efficiency, cache topology, and current pricing rather than raw class differences.
Hardware-wise, the Corsair MP700 PRO XT 2TB runs on Phison's E28 — the second-gen Gen 5 controller with refined efficiency over the original E26. The Samsung 990 EVO Plus 2TB pairs the dual-mode Samsung Piccolo silicon that uniquely runs PCIe 5.0 x2 or PCIe 4.0 x4.
Price separates these two meaningfully. The Samsung 990 EVO Plus 2TB costs $114.50/TB versus $209.50/TB for the Corsair MP700 PRO XT 2TB — a 45% premium that needs justification in real benchmarks, not just spec-sheet bragging.
Read speeds favor the Corsair MP700 PRO XT 2TB: 14,900 MB/s versus 7,250 MB/s for the Samsung 990 EVO Plus 2TB, a 51% advantage. Sequential-heavy workloads notice; transactional workloads don't.
The Corsair MP700 PRO XT 2TB writes about 50% faster (12,700 MB/s vs 6,300 MB/s). Whether that matters depends entirely on what you write to the drive — gameplay capture and large project saves benefit, browsing and gaming do not.
The Corsair MP700 PRO XT 2TB carries a dedicated DRAM chip for FTL (Flash Translation Layer) mapping; the Samsung 990 EVO Plus 2TB relies on HMB (Host Memory Buffer), borrowing 64 MB from system RAM. The practical gap shows up only under sustained random write loads.
Heading to a PlayStation 5? Both drives drop into the console's M.2 bay and report identical real-world benchmarks since the PS5 caps storage at PCIe 4.0 speeds. The Samsung 990 EVO Plus 2TB wins this matchup on $/TB. Heavy write workloads — video editing, RAW photo libraries, backup operations — favor the Corsair MP700 PRO XT 2TB's 12,700 MB/s sustained write speed. Both drives use the 2280 form factor, which is too long for Steam Deck or ROG Ally — you'd need a 2230 variant if either manufacturer offers one, or a dedicated handheld-format drive instead.
Pick the Corsair MP700 PRO XT 2TB if you value meaningfully faster reads (14,900 MB/s), higher sustained writes (12,700 MB/s), and a dedicated DRAM cache chip. Corsair's MP700 PRO XT brings Phison E28 silicon with optional heatsink variants — flexibility for both spacious desktops and laptops with motherboard clearance issues.
Pick the Samsung 990 EVO Plus 2TB if you value the lower retail price ($229 vs $419), and better $/TB economics ($114.50/TB). Among Samsung's lineup, the 990 EVO Plus is the only consumer drive that physically supports dual-generation PCIe — same hardware, different bus speed depending on platform.
