Nextorage NEM-PAB 1 TB: PlayStation 5-ready PCIe 4.0 NVMe with heatsink (2026)
The Nextorage NEM-PAB 1 TB is a PlayStation 5-ready PCIe 4.0 x4 NVMe SSD with a built-in heatsink, based on the Phison PS5027-E27T controller and Kioxia BiCS6 3D TLC NAND, rated 7,400 MB/s reads and 6,100 MB/s writes with 600 TBW of endurance and a 5-year warranty.
Controller & Memory
Nextorage, the Japanese storage brand spun off from Sony in 2019, sells the NEM-PAB as the heatsink-equipped, console-ready version of its NN4LE (G Series LE). Mechanically the drive is the same platform — the DRAM-less Phison PS5027-E27T controller with Kioxia BiCS6 162-layer 3D TLC NAND, using the host memory buffer in place of on-board DRAM — with a low-profile heatsink added so it drops straight into a PlayStation 5's M.2 expansion bay.
Nextorage lists the NEM-PAB as tested for compatibility with the PS5, PS5 Slim, and PS5 Pro, and the heatsink is sized to fit under the console's M.2 cover. The PS5 requires a PCIe 4.0 drive with sustained reads of at least 5,500 MB/s; at 7,400 MB/s the NEM-PAB clears that requirement comfortably, and the heatsink keeps the controller within the console's thermal envelope during gameplay.
The same drive works equally well in a PC PCIe 4.0 slot, where the heatsink helps thermals in a standard desktop. At 1 TB it is the entry capacity, which after the PS5's own system reservation leaves room for a handful of large modern games; buyers planning a big library may prefer the 2 TB or 4 TB. As an efficient, well-specified PS5-ready drive, the NEM-PAB 1 TB is a sound choice.

NEM-PAB Performance & Benchmarks
The NEM-PAB 1 TB is rated at 7,400 MB/s sequential reads and 6,100 MB/s sequential writes over PCIe 4.0 x4, with 1,000,000 random read IOPS and 850,000 random write IOPS. The 7,400 MB/s read comfortably exceeds the PlayStation 5's 5,500 MB/s requirement, so games load at full console speed.

- 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-PAB 1 TB (this drive): 7,400 MB/s read, 6,100 MB/s write
The built-in heatsink is the key functional addition over the bare NN4LE: it keeps the DRAM-less E27T controller cool inside the PS5's enclosed M.2 slot and in warm PC builds, preventing thermal throttling during sustained installs and copies. As the smallest capacity, the 1 TB has the most modest SLC write cache, so the longest sustained writes settle to native TLC speed sooner than on the larger models — not a factor in normal gameplay, which is read-dominated.

Endurance, TBW & Warranty
Nextorage covers the NEM-PAB with a 5-year warranty. The 1 TB model is rated for 600 TBW (terabytes written) and an MTBF of 1,500,000 hours, with coverage ending at whichever limit comes first: five years from purchase or 600 TBW of cumulative writes.
Game installs and updates write far less than sustained productivity workloads, so for console use the 600 TBW ceiling is effectively unreachable within the warranty. At a typical 30 GB per day it would take roughly 54 years to reach 600 TBW; even at 100 GB per day it spans about 16 years. The 5-year term is the practical limit, not the endurance rating.

Verdict: Is the NEM-PAB Worth It in 2026?
The Nextorage NEM-PAB 1 TB is a well-rounded PlayStation 5-ready drive: the efficient Phison E27T controller, current Kioxia BiCS6 TLC NAND, 7,400 MB/s reads that clear the PS5 requirement, a fitted low-profile heatsink, and a 5-year warranty with 600 TBW endurance from a Sony-derived Japanese brand.
It is a strong drop-in for a PS5 or a Gen4 PC where a cooled, no-fuss NVMe drive is wanted. At 1 TB, capacity is the main limit for console gamers with large libraries, who should consider the 2 TB or 4 TB NEM-PAB. Buyers who do not need a heatsink and only use the drive in a PC can save a little with the bare NN4LE equivalent.
+ Pros
- PlayStation 5-ready: 7,400 MB/s reads exceed the 5,500 MB/s requirement
