Side-by-side: Corsair MP700 PRO XT 2TB ($751) vs Samsung 990 EVO Plus 2TB ($370). $/TB winner, specs, real-world picks for September 2026.
Gen 5 at 2 TB is one of the most contested SSD segments in 2026, and Corsair MP700 PRO XT 2TB versus Samsung 990 EVO Plus 2TB captures that competition well. The decision rarely comes down to peak speeds — both drives saturate typical workloads.
Hardware-wise, the Corsair MP700 PRO XT 2TB runs on Phison's E28 design, manufactured on a more efficient process than the E26. The Samsung 990 EVO Plus 2TB pairs Samsung's Piccolo controller — DRAM-less with PCIe 4.0/5.0 dual-mode support.
Money matters here — $185.00/TB on the Samsung 990 EVO Plus 2TB versus $375.50/TB on the Corsair MP700 PRO XT 2TB. That's enough of a spread that for budget-conscious builders, the Samsung 990 EVO Plus 2TB becomes the default unless reviews of your specific workload prefer the Corsair MP700 PRO XT 2TB.
On sequential reads the Corsair MP700 PRO XT 2TB pulls ahead by 7,650 MB/s (14,900 MB/s versus 7,250 MB/s). That matters for moving large files but rarely shows up in game loads.
Write speeds skew toward the Corsair MP700 PRO XT 2TB: 12,700 MB/s sustained against 6,300 MB/s. Content creators feel this; gamers do not.
The DRAM-vs-HMB question divides opinion: Corsair MP700 PRO XT 2TB's on-board DRAM theoretically helps under sustained workloads, while Samsung 990 EVO Plus 2TB's HMB approach has matured enough that most users won't see the difference. Pick on price if everything else is similar.
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. Video editors will gravitate toward the Corsair MP700 PRO XT 2TB for its write headroom (12,700 MB/s sustained). Project saves and proxies move faster, which compounds across a workday. Heads-up — these are full-length 2280 drives. Steam Deck and most current handhelds require shorter 2230 modules, so check capacity-specific 2230 variants if that's your target platform.
Market context: we track 11 Gen 5 2 TB drives, and by price per terabyte the Corsair MP700 PRO XT 2TB currently sits #11 while the Samsung 990 EVO Plus 2TB sits #4. Neither cracks the top of the value table, so it's worth glancing at the alternatives below before picking either.
As of September 7, 2026, these tracked drives undercut both the Corsair MP700 PRO XT 2TB and Samsung 990 EVO Plus 2TB on $/TB:
Go with the Corsair MP700 PRO XT 2TB for meaningfully faster reads (14,900 MB/s), higher sustained writes (12,700 MB/s), and a dedicated DRAM cache chip. Corsair pairs the E28 controller with quality Kioxia BiCS8 NAND in the MP700 PRO XT — same flash class as the WD SN8100 at a different price point.
Go with the Samsung 990 EVO Plus 2TB for the lower retail price ($370 vs $751), and better $/TB economics ($185.00/TB). The 990 EVO Plus uniquely supports both PCIe 4.0 x4 and PCIe 5.0 x2 modes — useful flexibility if you might upgrade motherboard generations.
