Samsung 9100 PRO w/ Heatsink 2TB ($595) vs Samsung 990 PRO 2TB ($389). $/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 w/ Heatsink 2TB runs on Samsung's Presto controller — built in-house to push V-NAND to its Gen 5 ceiling. The Samsung 990 PRO 2TB pairs Samsung's 8nm Pascal controller, the silicon powering the 990 PRO line.
The cost difference is hard to ignore: 35% per TB (Samsung 990 PRO 2TB at $194.50/TB versus Samsung 9100 PRO w/ Heatsink 2TB at $297.50/TB). Unless you specifically need the Samsung 9100 PRO w/ Heatsink 2TB's peak performance, the Samsung 990 PRO 2TB delivers more storage for the money.

If this purchase is for a PS5 storage expansion, the comparison flattens — Sony's PCIe Gen 4 controller normalizes both Samsung 9100 PRO w/ Heatsink 2TB and Samsung 990 PRO 2TB to roughly equal in-game load times. The cheaper drive is the smart pick. The Gen 5 Samsung 9100 PRO w/ Heatsink 2TB 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 w/ Heatsink 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: the Samsung 9100 PRO w/ Heatsink 2TB ranks #10 of 11 Gen 5 2 TB drives we track by $/TB, while the Samsung 990 PRO 2TB ranks #7 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.
