Samsung 9100 PRO 4TB ($898) vs TeamGroup MP44 4TB ($513). $/TB analysis, performance, and use-case recommendations.
When generations cross paths in a comparison like this one, the older-spec drive almost always wins on value while the newer one wins on benchmarks. Whether that benchmark advantage matters depends entirely on what you do with the drive.
Hardware-wise, the Samsung 9100 PRO 4TB runs on Samsung's Presto controller — built in-house to push V-NAND to its Gen 5 ceiling. The TeamGroup MP44 4TB pairs the MaxioTech MAP1602 — a DRAM-less Gen 4 controller dominating the value tier across TeamGroup, Lexar, and others.
The cost difference is hard to ignore: 43% per TB (TeamGroup MP44 4TB at $128.25/TB versus Samsung 9100 PRO 4TB at $224.50/TB). Unless you specifically need the Samsung 9100 PRO 4TB's peak performance, the TeamGroup MP44 4TB delivers more storage for the money.
On sequential reads the Samsung 9100 PRO 4TB pulls ahead by 7,400 MB/s (14,800 MB/s versus 7,400 MB/s). That matters for moving large files but rarely shows up in game loads.
Write speeds skew toward the Samsung 9100 PRO 4TB: 13,400 MB/s sustained against 6,000 MB/s. Content creators feel this; gamers do not.
Cache architecture differs: Samsung 9100 PRO 4TB has DRAM hardware, TeamGroup MP44 4TB uses HMB. For OS, gaming, browsing — indistinguishable. For databases, large file ops, or 4K video editing — DRAM has a small but consistent edge.
For PS5 expansion, both are PCIe Gen 4 M.2 2280 drives that meet Sony's minimum spec (7,400 MB/s read). The console can't take advantage of speeds beyond that, so save money by choosing the TeamGroup MP44 4TB. The Gen 5 Samsung 9100 PRO 4TB pulls ahead on sequential bandwidth, but Gen 5 advantages rarely surface during everyday tasks — most software hasn't been rewritten to exploit 14,000+ MB/s pipelines. Video editors will gravitate toward the Samsung 9100 PRO 4TB 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: the Samsung 9100 PRO 4TB ranks #5 of 6 Gen 5 4 TB drives we track by $/TB, while the TeamGroup MP44 4TB ranks #2 of 6 Gen 4 4 TB drives. 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 4TB and TeamGroup MP44 4TB on $/TB:
The Samsung 9100 PRO 4TB is the right call if meaningfully faster reads (14,800 MB/s), higher sustained writes (13,400 MB/s), and a dedicated DRAM cache chip 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 MP44 4TB is the right call if the lower retail price ($513 vs $898), and better $/TB economics ($128.25/TB) matter to you. The TeamGroup MP44 4TB 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.
