# Nextorage NEM-PAC 2 TB: the recommended PS5-optimised SSD with heatsink (2026)

The Nextorage NEM-PAC 2 TB is a PlayStation 5-optimised PCIe 4.0 x4 NVMe SSD with an integrated, non-removable heatsink, based on the Phison PS5027-E27T controller and Kioxia BiCS6 3D TLC NAND, rated 7,400 MB/s reads and 6,400 MB/s writes with a 5-year warranty.

Quick answer: The Nextorage NEM-PAC 2 TB is the pick of the PS5-optimised line: the Phison E27T controller and Kioxia BiCS6 TLC NAND of the NEM-PAB, full 7,400/6,400 MB/s performance, a high write IOPS rating, and an integrated cooling structure tuned for the PlayStation 5 — backed by a 5-year warranty and reviewed favourably by Tom's Hardware.

| Warranty | 5 years |

## Performance

The NEM-PAC 2 TB is rated at 7,400 MB/s sequential reads and 6,400 MB/s sequential writes over PCIe 4.0 x4, with 800,000 random read IOPS and 1,050,000 random write IOPS. The read speed exceeds the PlayStation 5's 5,500 MB/s requirement, so games load at full console speed, and the high write IOPS suit the console's install and update behaviour.

The 2 TB's larger NAND array delivers a bigger SLC write cache and stronger sustained write than the 1 TB, so large installs and copies hold higher speed for longer. The integrated cooling structure is designed to keep the drive stable through extended PS5 sessions in the console's enclosed M.2 slot, where airflow is limited. Tom's Hardware's review found it a dependable PS5 performer.

## Endurance, TBW & Warranty

Nextorage covers the NEM-PAC with a 5-year warranty and a 1,500,000-hour MTBF. Nextorage does not separately publish a TBW figure for the NEM-PAC; based on the same Kioxia BiCS6 TLC NAND used across the line at a 600 TBW-per-terabyte rate, the 2 TB is estimated at 1,200 TBW. Coverage ends at whichever comes first: five years or the rated endurance.

Console and desktop workloads write far below this ceiling, so endurance is not a practical limit within the warranty term. At a typical 30 GB of writes per day, 1,200 TBW would take well over a century to reach. The 5-year warranty is the binding factor.

## Pros and Cons

**Pros:**

- Full 7,400/6,400 MB/s with a high 1,050,000 write IOPS rating
- PlayStation 5-optimised integrated cooling structure
- 2 TB balances capacity and price for console libraries
- Phison E27T with Kioxia BiCS6 162-layer 3D TLC NAND
- Reviewed by Tom's Hardware as a solid PS5 performer
- 5-year warranty
**Cons:**

- Non-removable heatsink can interfere with PC motherboard M.2 covers
- DRAM-less (HMB) — no dedicated DRAM cache
- Nextorage does not separately publish a TBW rating for the line
- Lower random read IOPS (800,000) than write
- Limited Western retail availability


## Verdict

The Nextorage NEM-PAC 2 TB is the pick of the PS5-optimised line: the Phison E27T controller and Kioxia BiCS6 TLC NAND of the NEM-PAB, full 7,400/6,400 MB/s performance, a high write IOPS rating, and an integrated cooling structure tuned for the PlayStation 5 — backed by a 5-year warranty and reviewed favourably by Tom's Hardware.

It is a clean, well-balanced drop-in for a PS5 at the capacity most owners should choose. The considerations are the non-removable heatsink, which can complicate PC use, and the line's unpublished TBW. Buyers who specifically want the same hardware for a PC M.2 slot with its own cover should look at the NEM-PAB or bare NN4LE.

## Frequently Asked Questions

### Is the NEM-PAC 2 TB a good PlayStation 5 SSD?

Yes. Tom's Hardware reviewed the NEM-PAC 2 TB as a solid, PS5-ready drive. It is PCIe 4.0 rated 7,400 MB/s — above the console's 5,500 MB/s requirement — with an integrated cooling structure tuned for the PS5 and a high write IOPS rating. At 2 TB it offers a good balance of capacity and price for a console library.

### How does the NEM-PAC 2 TB differ from the 1 TB?

The 2 TB reaches the full 6,400 MB/s sequential write, whereas the 1 TB is rated lower at 4,800 MB/s. The 2 TB also has a larger SLC cache and stronger sustained write, plus double the capacity and estimated endurance. For most PS5 owners the 2 TB is the better-rounded choice.

### Can the NEM-PAC 2 TB be used in a PC?

Yes, it is a standard PCIe 4.0 NVMe drive. The consideration is its integrated, non-removable heatsink, which may conflict with a motherboard's own M.2 heatsink or cover. For unconstrained PC use, the NEM-PAB or bare NN4LE — identical controller and NAND — are more flexible.

### What controller and NAND does the NEM-PAC 2 TB use?

It uses the Phison PS5027-E27T, a four-channel, DRAM-less PCIe 4.0 controller, with Kioxia BiCS6 162-layer 3D TLC NAND and the host memory buffer in place of on-board DRAM — the same platform as the NEM-PAB, with PS5-focused tuning and an integrated heatsink.

### What is the TBW endurance of the NEM-PAC 2 TB?

Nextorage does not separately publish a TBW rating for the NEM-PAC. Based on the same Kioxia BiCS6 TLC NAND used across the line at 600 TBW per terabyte, the 2 TB is estimated at 1,200 TBW, with a 5-year warranty and 1,500,000-hour MTBF. Console workloads write far below this, so the warranty term is the practical limit.
