Side-by-side: Samsung 990 EVO Plus 2TB ($369) vs Samsung 990 PRO 2TB ($388). $/TB winner, specs, real-world picks for July 2026.
This is a generational matchup at 2 TB: the older-gen drive offers proven reliability and better $/TB, while the newer-gen sibling brings raw bandwidth that most users never tap.
Hardware-wise, the Samsung 990 EVO Plus 2TB runs on Samsung's Piccolo — a DRAM-less controller with flexible PCIe generation support. The Samsung 990 PRO 2TB pairs Samsung's 8nm Pascal controller, the silicon powering the 990 PRO line.
The DRAM-vs-HMB question divides opinion: Samsung 990 PRO 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.
For PS5 expansion, both are PCIe Gen 4 M.2 2280 drives that meet Sony's minimum spec (7,250 MB/s read). The console can't take advantage of speeds beyond that, so save money by choosing the Samsung 990 EVO Plus 2TB. Comparing across generations always invites the same question: does the bandwidth gap convert into user-visible improvements? Honest answer for the Samsung 990 EVO Plus 2TB vs Samsung 990 PRO 2TB pairing: only for sustained sequential reads of multi-GB files. Video editors will gravitate toward the Samsung 990 PRO 2TB for its write headroom (6,900 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: the Samsung 990 EVO Plus 2TB ranks #4 of 11 Gen 5 2 TB drives we track by $/TB, while the Samsung 990 PRO 2TB ranks #10 of 11 Gen 4 2 TB drives. Neither cracks the top of the value table, so it's worth glancing at the alternatives below before picking either.
As of July 27, 2026, these tracked drives undercut both the Samsung 990 EVO Plus 2TB and Samsung 990 PRO 2TB on $/TB:
Go with the Samsung 990 EVO Plus 2TB for the lower retail price ($369 vs $388), and better $/TB economics ($184.50/TB). Samsung designed the 990 EVO Plus around the Piccolo controller's dual-PCIe support — a hedge against both Gen 4 holdouts and Gen 5 early adopters.
Go with the Samsung 990 PRO 2TB for a dedicated DRAM cache chip. Samsung's PRO line has the longest track record for firmware reliability — over a decade of consumer SSDs with global RMA support.
