Crucial T500 1TB ($288) vs WD Blue SN5100 1TB ($180). $/TB analysis, performance, and use-case recommendations.
Crucial T500 1TB and WD Blue SN5100 1TB are direct competitors — same generation, same capacity. Choose by controller behavior under sustained load, DRAM/HMB cache strategy, and $/TB economics.
Hardware-wise, the Crucial T500 1TB runs on Phison's E25 silicon, found in many DRAM-equipped Gen 4 SSDs. The WD Blue SN5100 1TB pairs the SanDisk controller.
The cost difference is hard to ignore: 38% per TB (WD Blue SN5100 1TB at $180.00/TB versus Crucial T500 1TB at $288.00/TB). Unless you specifically need the Crucial T500 1TB's peak performance, the WD Blue SN5100 1TB delivers more storage for the money.
Cache architecture differs: Crucial T500 1TB has DRAM hardware, WD Blue SN5100 1TB uses HMB. For OS, gaming, browsing — indistinguishable. For databases, large file ops, or 4K video editing — DRAM has a small but consistent edge.
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 WD Blue SN5100 1TB wins this matchup on $/TB. For content creators routinely rendering 4K or 8K video, the Crucial T500 1TB's 6,800 MB/s sustained write is the deciding factor — multi-GB project files land noticeably faster than on the alternative. Note for handheld gamers: M.2 2280 is the desktop/laptop standard. Steam Deck and the ROG Ally line need 2230 drives — neither Crucial T500 1TB nor WD Blue SN5100 1TB fits without modification.
Zoom out from this pair for a moment. Among the 4 Gen 4 1 TB drives we track, the Crucial T500 1TB ranks #4 by $/TB and the WD Blue SN5100 1TB ranks #1. One of them is genuinely among the cheapest options in its class, so this matchup includes a real value pick.

The Crucial T500 1TB is the right call if higher sustained writes (6,800 MB/s), and a dedicated DRAM cache chip matter to you. Crucial typically delivers the best $/TB among DRAM-equipped NVMes because Micron sells direct rather than going through brand licensing.
The WD Blue SN5100 1TB is the right call if the lower retail price ($180 vs $288), and better $/TB economics ($180.00/TB) matter to you.
