# Apacer AS2280Q4U 2TB: A PS5-Ready PCIe 4.0 NVMe SSD (2026)

The Apacer AS2280Q4U 2TB pairs a Phison E18 controller with 176-layer Micron TLC NAND to hit 7,400 MB/s reads, making it one of the more capable PS5-marketed PCIe 4.0 drives around.

Quick answer: The AS2280Q4U 2TB suits PS5 owners and PC builders who want flagship-tier PCIe 4.0 speed without paying Samsung or WD pricing, and who don't mind sourcing their own heatsink. Buyers who want a documented sustained-write spec sheet or a longer independent review track record should lean toward the WD Black SN850X or Corsair MP600 Pro NH instead, since both have deeper third-party testing behind their numbers. If a heatsink is a hard requirement out of the box, Apacer's own PS5-specific variant or a rival with a bundled heatsink is the simpler choice. For anyone comfortable adding a heatsink and buying on spec rather than reputation, the 7,400/7,000 MB/s rating and 1,500 TBW endurance make this a reasonable value pick in the 2TB PCIe 4.0 tier.

## Performance

The 2TB AS2280Q4U is rated for 7,400 MB/s sequential reads and 7,000 MB/s sequential writes, with random performance rated up to 1,000,000 IOPS on both reads and writes. Those numbers put it near the top of the PCIe 4.0 tier, on par with drives like the WD Black SN850X rather than the mid-range Gen4 field. In practice, sequential reads this high mostly matter for large sequential transfers: game installs, video export, and level-load streaming benefit more than everyday desktop use, where NVMe drives already feel instant compared to SATA.

Like every TLC drive in this class, the AS2280Q4U leans on an SLC write cache to hit its peak write number; once a sustained transfer outruns that cache, throughput drops toward the NAND's native TLC write speed. Apacer does not publish the exact cache size or post-cache speed for this model, so buyers moving very large files (100GB-plus video masters, bulk game library transfers) should expect some slowdown partway through rather than a flat 7,000 MB/s the whole way. For PS5 use, this speed comfortably clears Sony's 5,500 MB/s read minimum for expansion storage, and for PC gaming it's fast enough to make full use of DirectStorage-enabled titles without the drive being the bottleneck.

## Endurance, TBW & Warranty

The 2TB AS2280Q4U carries a 1,500 TBW endurance rating and a 5-year warranty, with the warranty ending whichever limit is hit first. At a realistic consumer workload of 30 to 50GB written per day, 1,500 TBW works out to roughly 80 to 135 years before the rated endurance is exhausted, which is far beyond the 5-year warranty window and beyond the practical life of the drive itself. Apacer also lists an MTBF of 1,600,000 hours, a population-level reliability statistic rather than a guarantee for any individual unit, but broadly in line with other Phison E18 drives in this class. Apacer's own product page is light on published per-capacity TBW figures compared to rivals like Western Digital or Samsung, so buyers relying on documented endurance for warranty claims should keep the retailer receipt and check Apacer's RMA process, which typically routes through the reseller rather than direct manufacturer support in most regions.

## Pros and Cons

**Pros:**

- 7,400 MB/s sequential reads on PCIe 4.0
- 7,000 MB/s sequential writes at 2TB
- 1,500 TBW endurance rating
- 5-year manufacturer warranty
- DRAM cache paired with Phison E18 controller
- Marketed and spec-validated for PS5 expansion storage
**Cons:**

- No heatsink included on this bare M.2 SKU
- Apacer publishes little per-capacity TBW documentation
- Fewer independent reviews than Samsung or WD rivals
- 500GB variant in this line writes at 3,000 MB/s


## Verdict

The AS2280Q4U 2TB suits PS5 owners and PC builders who want flagship-tier PCIe 4.0 speed without paying Samsung or WD pricing, and who don't mind sourcing their own heatsink. Buyers who want a documented sustained-write spec sheet or a longer independent review track record should lean toward the WD Black SN850X or Corsair MP600 Pro NH instead, since both have deeper third-party testing behind their numbers. If a heatsink is a hard requirement out of the box, Apacer's own PS5-specific variant or a rival with a bundled heatsink is the simpler choice. For anyone comfortable adding a heatsink and buying on spec rather than reputation, the 7,400/7,000 MB/s rating and 1,500 TBW endurance make this a reasonable value pick in the 2TB PCIe 4.0 tier.

## Frequently Asked Questions

### Is the Apacer AS2280Q4U 2TB good for gaming?

Yes. Its 7,400 MB/s reads and PCIe 4.0 interface are fast enough for quick game installs, level streaming, and DirectStorage-enabled titles on PC. On a PS5, it clears Sony's minimum read-speed requirement comfortably, so games load about as fast as they would from the console's internal drive. The 2TB capacity also leaves enough headroom for a large modern game library without constant uninstall-reinstall cycles.

### Is the AS2280Q4U 2TB compatible with the PS5?

Sony requires PCIe 4.0 NVMe storage rated at 5,500 MB/s or faster reads, with the drive fitting within 110 x 25 x 11.25mm including any heatsink. The AS2280Q4U 2TB's 7,400 MB/s rating clears that bar, and Apacer explicitly markets this model for PS5 expansion storage, though buyers should add a heatsink since the bare version doesn't ship with one.

### Does the Apacer AS2280Q4U have a DRAM cache?

Yes. It uses a dedicated DRAM chip alongside the Phison PS5018-E18 controller to hold the flash translation layer's mapping tables, rather than relying on host memory buffer. That generally means steadier random-access performance under mixed workloads compared to DRAM-less drives in the same price range, especially once the drive's address tables grow large on a mostly-full 2TB volume.

### What is the TBW endurance of the 2TB AS2280Q4U?

The 2TB model is rated for 1,500 TBW, backed by a 5-year warranty. For a typical desktop or PS5 workload writing 30 to 50GB per day, that endurance rating would take roughly 80 to 135 years to exhaust, well beyond both the warranty period and the drive's realistic service life.

### Does the AS2280Q4U need a heatsink?

The base M.2 SKU doesn't include one, and a Phison E18 controller running at 7,000 MB/s-plus writes will throttle under sustained load without adequate cooling. Desktop motherboards with an M.2 heatsink slot cover this automatically; PS5 installs and heatsink-less laptops should add a low-profile aftermarket heatsink or use Apacer's dedicated PS5 SKU that ships with one.

### How does the 2TB compare to the 500GB and 1TB AS2280Q4U?

The 2TB capacity is where this line hits its full rated speed. The 500GB model drops to around 3,000 MB/s writes due to fewer NAND dies for parallelism, and the 1TB sits at roughly 6,000 MB/s, so the 2TB (and larger) capacities are the ones that deliver the 7,400/7,000 MB/s numbers Apacer advertises for the series.

### How does the AS2280Q4U 2TB compare to the Corsair MP600 Pro NH or WD Black SN850X?

All three sit in the same PCIe 4.0 flagship tier with comparable 7,000 MB/s-plus speeds and DRAM caches. The SN850X and MP600 Pro NH have more independent benchmark coverage and, in the SN850X's case, WD's own SSD Dashboard software; the AS2280Q4U competes mainly on price for buyers who don't need that extra documentation or software polish.
