Addlink H90 2TB Review — Phison E16 PCIe 4.0 NVMe SSD
The Addlink H90 2 TB doubles the already-exceptional endurance of the 1 TB variant to 3,600 TBW, making it one of the few 2 TB drives ever sold where the warranty is genuinely more likely to expire than the NAND — by a margin measured in centuries.
The 2 TB Addlink H90 is built on the same Phison PS5016-E16 platform as the 1 TB variant — an 8-channel PCIe 4.0 controller with DDR4 DRAM and 3D TLC NAND. The 2 TB capacity doubles the endurance to 3,600 TBW and provides a larger SLC write cache by virtue of the additional NAND. Sequential speeds remain 5,000 MB/s read and 4,400 MB/s write — the E16 controller ceiling is the same regardless of capacity. The drive uses a double-sided M.2 2280 PCB with the PCIe 4.0 x4 interface.
The H90 family includes 1 TB and 2 TB capacities, with endurance scaling linearly: 1,800 TBW at 1 TB and 3,600 TBW at 2 TB. The 2 TB reviewed here is the fully documented E16 pick for buyers who want maximum endurance in a single-drive desktop solution. It competes against other E16 2 TB drives — the Corsair MP600 2 TB, the Sabrent Rocket 4.0 2 TB, and ADATA's XPG Gammix S50 2 TB — all of which share the same controller DNA with minor variations in NAND vendor and firmware.
The H90 2 TB is a desktop drive through and through. The E16 requires a heatsink and airflow, and the double-sided PCB may not clear thin M.2 slots in ITX boards or laptops. For a standard ATX desktop build with an M.2 heatsink, it is a capable and fully documented 2 TB PCIe 4.0 drive with endurance numbers that make modern flagships look disposable by comparison.
✅ Storage Comparisons:
🚀 Performance and benchmarks
The H90 2 TB is rated at up to 5,000 MB/s sequential reads and 4,400 MB/s sequential writes — identical to the 1 TB. Random performance is rated at up to 750,000 read IOPS and 700,000 write IOPS. In practice, game loads and desktop use are indistinguishable from any PCIe 4.0 NVMe drive. The 2 TB capacity benefits from a larger SLC write cache (roughly 300—400 GB) and greater NAND parallelism, which helps sustain higher post-cache write speeds compared to the 1 TB.

- PNY XLR8 CS3140 1 TB: 7,500 MB/s read, 5,650 MB/s write
- PNY XLR8 CS3140 2 TB: 7,500 MB/s read, 6,850 MB/s write
- Asgard AN4 512 GB: 7,500 MB/s read, 5,500 MB/s write
- Asgard AN4 1 TB: 7,500 MB/s read, 5,500 MB/s write
- Addlink H90 2 TB (this drive): 5,000 MB/s read, 4,400 MB/s write
Like all E16 drives, the H90 uses a pSLC cache to absorb burst writes, with direct-to-TLC writes settling to roughly 1,200—1,500 MB/s after the cache fills. Sustained sequential writes demand a heatsink — the E16 will hit 75 °C and thermal-throttle within minutes on a bare drive. A motherboard M.2 heatsink with case airflow is the minimum requirement. The drive is not suited for laptops or passive-cooled enclosures.
🖥️ Endurance and warranty
The 2 TB Addlink H90 carries a 3,600 TBW endurance rating and a 5-year limited warranty. At a typical 50 GB/day write rate, this translates to roughly 200 years of continuous use — the warranty will expire long before the NAND cells approach their endurance ceiling. The MTBF is rated at 1.8 million hours. For comparison, the Samsung 990 Pro 2 TB is rated at 1,200 TBW and the WD Black SN850X 2 TB at 1,200 TBW — the H90 offers triple. The Phison E16 platform's endurance figures are a consequence of conservative NAND management and heavy over-provisioning from an era before manufacturers aggressively trimmed endurance to reduce cost. Addlink handles warranty through its distribution network.

Conclusion
The Addlink H90 2 TB is the endurance champion of Addlink's E16 lineup — a fully documented, DRAM-equipped PCIe 4.0 drive whose 3,600 TBW rating makes the most demanding write workloads irrelevant. Buy it if endurance is your primary concern, you have a desktop with M.2 cooling, and you value a complete spec sheet from a smaller brand. Skip it if you need modern PCIe 4.0 speeds — the second-gen E18 drives offer 40% more throughput — or if you need a laptop-compatible drive. The H90 2 TB is a specialist: a write-heavy workhorse whose endurance headroom borders on absurd, and for the right desktop workload, that is exactly the point.
+ Pros
