Samsung 9100 PRO 2TB ($400) vs TeamGroup Z540 2TB ($329). $/TB analysis, performance, and use-case recommendations.
Samsung 9100 PRO 2TB and TeamGroup Z540 2TB are direct competitors — same generation, same capacity. Choose by controller behavior under sustained load, DRAM/HMB cache strategy, and $/TB economics.
Hardware-wise, the Samsung 9100 PRO 2TB runs on Samsung's Presto controller — built in-house to push V-NAND to its Gen 5 ceiling. The TeamGroup Z540 2TB pairs the Phison E26 — the first widely-deployed Gen 5 controller, capable but thermally demanding.
The cheaper drive — TeamGroup Z540 2TB at $164.50/TB — saves you $35.50 per TB versus the Samsung 9100 PRO 2TB. Worth it if you're capacity-constrained; either works if you just want one fast drive.
For PlayStation 5 builds, the console's internal M.2 slot tops out around 5,500 MB/s sustained, so both Samsung 9100 PRO 2TB and TeamGroup Z540 2TB hit the same wall — pick whichever is cheaper at the moment you buy. Video editors will gravitate toward the Samsung 9100 PRO 2TB for its write headroom (13,400 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 Samsung 9100 PRO 2TB currently sits #7 while the TeamGroup Z540 2TB sits #2. One of them is genuinely among the cheapest options in its class, so this matchup includes a real value pick.
As of July 27, 2026, these tracked drives undercut both the Samsung 9100 PRO 2TB and TeamGroup Z540 2TB on $/TB:
The Samsung 9100 PRO 2TB is the right call if meaningfully faster reads (14,700 MB/s), and higher sustained writes (13,400 MB/s) matter to you. Samsung backs the PRO series with one of the strongest warranty experiences in consumer storage — RMAs typically process within 5 business days globally.
The TeamGroup Z540 2TB is the right call if the lower retail price ($329 vs $400), and better $/TB economics ($164.50/TB) matter to you. The TeamGroup Z540 2TB wins on $/TB because it pairs DRAM-less MAP1602 silicon with low-margin distribution. Performance is fine for OS and gaming, weaker only on sustained random writes.
