Apacer AS2280Q4 1TB Review — Phison E16 PCIe 4.0 NVMe SSD
The Apacer AS2280Q4 1 TB is the practical capacity in Apacer's Phison E16 lineup — enough space for a game library and an OS, with the same 8-channel DRAM controller as drives that cost more, tempered by a 3-year warranty and a spec sheet that omits endurance figures.
The 1 TB Apacer AS2280Q4 is built on the Phison PS5016-E16, the first-gen PCIe 4.0 8-channel controller with DDR4 DRAM and 3D TLC NAND. Apacer rates all AS2280Q4 capacities identically at 5,000 MB/s read and 4,400 MB/s write, with 750,000 IOPS for both reads and writes. The 1 TB capacity strikes a balance — enough space for an OS, a substantial game library, and media — and is the volume seller in the family. The drive uses the M.2 2280 form factor with the PCIe 4.0 x4 interface.
The AS2280Q4 family spans 500 GB, 1 TB, and 2 TB. The 1 TB is the sweet spot: it doubles the capacity of the 500 GB for a modest price increase, and unlike the 500 GB it is viable as a single-drive solution for a gaming or general-purpose desktop. Apacer does not publish TBW endurance for any capacity, and the warranty is 3 years — shorter than the 5-year standard on competing E16 drives from Corsair and Sabrent. These are the cost-cutting measures that let Apacer position the AS2280Q4 below brand-name competitors.
The AS2280Q4 competes against other budget E16 drives and modern DRAM-less PCIe 4.0 alternatives. The E16 hardware — 8 channels, DDR4 DRAM, mature firmware — is a genuine differentiator against DRAM-less HMB drives that have similar or better headline speeds but weaker sustained mixed-workload performance. The trade-off is the shorter warranty and absent endurance documentation. For a budget-conscious desktop builder who values the E16 controller over a spec sheet, the AS2280Q4 1 TB is a hardware-first proposition.
✅ Storage Comparisons:
🚀 Performance and benchmarks
The AS2280Q4 1 TB is rated at 5,000 MB/s read and 4,400 MB/s write — identical on paper to the 500 GB and 2 TB variants. Random IOPS are rated at 750,000 for both reads and writes. In practice, game loads, OS boots, and application launches are indistinguishable from any NVMe drive. The 1 TB capacity provides a larger SLC write cache than the 500 GB — roughly 150—200 GB based on E16 platform behaviour — and direct-to-TLC writes settle in the 1,200—1,500 MB/s range.

- 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
- Apacer AS2280Q4 1 TB (this drive): 5,000 MB/s read, 4,400 MB/s write
The E16 controller requires a heatsink. Sustained writes will push the controller past 75 °C within minutes on a bare drive, and thermal throttling will cut performance by 30—50%. A motherboard M.2 heatsink with case airflow is the minimum. The drive is a desktop proposition — the E16's power draw and thermals rule out laptop use.
🖥️ Endurance and warranty
Apacer does not publish a TBW endurance figure for the AS2280Q4. The drive carries a 3-year warranty — shorter than the 5-year standard on competing Phison E16 drives — and an MTBF of 1.5 million hours. For reference, other 1 TB E16 TLC drives were rated at 700—1,800 TBW depending on NAND grade and over-provisioning. Without a published figure from Apacer, buyers should treat the 3-year warranty as the practical coverage limit. Apacer handles warranty through its distribution channels.

Conclusion
The Apacer AS2280Q4 1 TB is a budget E16 drive that prioritises controller hardware over documentation. It delivers the same 8-channel DRAM-equipped Phison E16 as the Corsair MP600 and Sabrent Rocket 4.0, at a lower price, with a shorter warranty and blank cells where the endurance and DRAM specs should be. Buy it if you understand the E16 platform and want the cheapest possible entry into an 8-channel PCIe 4.0 drive with DRAM. Skip it if you need a 5-year warranty, published endurance, or the reassurance of a brand-name support network — the Corsair MP600 1 TB or a modern DRAM-less TLC alternative like the WD Black SN770 will serve you with fewer asterisks.
+ Pros
