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.
Controller & Memory
Nextorage, the Sony-derived Japanese storage brand, sells the NEM-PAC as its most PlayStation 5-focused drive, and the 2 TB is the capacity Tom's Hardware reviewed and described as a 'solid, PS5-ready workhorse'. It uses the same DRAM-less Phison PS5027-E27T controller and Kioxia BiCS6 162-layer 3D TLC NAND as the NEM-PAB, with an integrated, non-removable heatsink and a cooling structure tuned for stable performance during long console sessions.
Unlike the 1 TB, which carries a lower sequential write rating, the 2 TB reaches the full 7,400/6,400 MB/s and pairs it with a high 1,050,000 write IOPS rating, so it behaves like the top of the line for both reads and writes. The 7,400 MB/s read comfortably clears the PlayStation 5's 5,500 MB/s requirement, and 2 TB is the balance most console owners want — enough room for a meaningful game library alongside the console's internal storage.
It also works in a PC PCIe 4.0 slot, with the caveat that the fixed heatsink may interfere with a motherboard's own M.2 cover. For a PS5, though, the 2 TB NEM-PAC is a clean, well-tuned drop-in, and the capacity that makes the most sense for most buyers.

NEM-PAC Performance & Benchmarks
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.

- Patriot Viper PV593 1 TB: 14,500 MB/s read, 14,000 MB/s write
- Patriot Viper PV593 2 TB: 14,500 MB/s read, 14,000 MB/s write
- Patriot Viper PV593 4 TB: 14,500 MB/s read, 14,000 MB/s write
- Patriot Viper PV573 2 TB: 14,000 MB/s read, 12,000 MB/s write
- Nextorage NEM-PAC 2 TB (this drive): 7,400 MB/s read, 6,400 MB/s write
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.

Verdict: Is the NEM-PAC Worth It in 2026?
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.
