Compare Crucial T500 1TB and WD Blue SN5100 1TB: prices, speeds, $/TB. Which to buy in May 2026? Full spec breakdown.
Both the Crucial T500 1TB and WD Blue SN5100 1TB sit in the Gen 4 category at 1 TB, so the matchup turns on controller efficiency, cache topology, and current pricing rather than raw class differences.
Hardware-wise, the Crucial T500 1TB runs on the Phison E25 — a refined Gen 4 controller widely used in mid-range NVMe drives. The WD Blue SN5100 1TB pairs the SanDisk controller.
There's a modest pricing advantage for the WD Blue SN5100 1TB: $89.00/TB compared with $115.00/TB. For typical gaming and productivity, this becomes the deciding factor when specs are close.
The Crucial T500 1TB carries a dedicated DRAM chip for FTL (Flash Translation Layer) mapping; the WD Blue SN5100 1TB relies on HMB (Host Memory Buffer), borrowing 64 MB from system RAM. The practical gap shows up only under sustained random write loads.
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. Heavy write workloads — video editing, RAW photo libraries, backup operations — favor the Crucial T500 1TB's 6,800 MB/s sustained write speed. Both drives use the 2280 form factor, which is too long for Steam Deck or ROG Ally — you'd need a 2230 variant if either manufacturer offers one, or a dedicated handheld-format drive instead.
Pick the Crucial T500 1TB if you value higher sustained writes (6,800 MB/s), and a dedicated DRAM cache chip. Crucial drives benefit from being a direct Micron product — the same NAND that powers competitors' drives, but at lower margins.
Pick the WD Blue SN5100 1TB if you value the lower retail price ($89 vs $115), and better $/TB economics ($89.00/TB).
