Compare WD_BLACK SN8100 2TB and Crucial T500 2TB: prices, speeds, $/TB. Which to buy in July 2026? Full spec breakdown.
WD_BLACK SN8100 2TB vs Crucial T500 2TB pits two different generations against each other at 2 TB. The question isn't which is faster on paper — that's settled — it's whether the bandwidth gap shows up in your specific workload.
Hardware-wise, the WD_BLACK SN8100 2TB runs on SMI's SM2508 silicon, which became the default Gen 5 controller for power-conscious flagships. The Crucial T500 2TB pairs the Phison E25 — a refined Gen 4 controller widely used in mid-range NVMe drives.
On sequential reads the WD_BLACK SN8100 2TB pulls ahead by 7,500 MB/s (14,900 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 WD_BLACK SN8100 2TB: 11,000 MB/s sustained against 7,000 MB/s. Content creators feel this; gamers do not.
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 Crucial T500 2TB wins this matchup on $/TB. The leap from Gen 4 to Gen 5 doubles peak throughput on paper but produces single-digit-percent improvements in game load times, OS boot, and most productivity benchmarks. The Crucial T500 2TB is the better default unless you have a specific workload that needs the extra lanes. Video editors will gravitate toward the WD_BLACK SN8100 2TB for its write headroom (11,000 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 WD_BLACK SN8100 2TB ranks #5 of 11 Gen 5 2 TB drives we track by $/TB, while the Crucial T500 2TB ranks #9 of 11 Gen 4 2 TB drives. Neither is a value leader right now — if $/TB is your priority, check the cheaper alternatives below before committing.
As of July 27, 2026, these tracked drives undercut both the WD_BLACK SN8100 2TB and Crucial T500 2TB on $/TB:
Pick the WD_BLACK SN8100 2TB if you value meaningfully faster reads (14,900 MB/s), and higher sustained writes (11,000 MB/s).
Pick the Crucial T500 2TB if you value the lower retail price ($369 vs $380), and better $/TB economics ($184.50/TB). Crucial drives benefit from being a direct Micron product — the same NAND that powers competitors' drives, but at lower margins.
