# 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.

Quick answer: 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.

## Performance

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.

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.

## Pros and Cons

**Pros:**

- PlayStation 5-ready: 7,400 MB/s reads exceed the 5,500 MB/s requirement
- Low-profile heatsink fits under the PS5 M.2 cover
- Phison E27T with Kioxia BiCS6 162-layer 3D TLC NAND
- 5-year warranty with 600 TBW endurance
- Works equally well as a cooled PC Gen4 drive
- Efficient DRAM-less design runs cool under the heatsink
**Cons:**

- DRAM-less (HMB) — no dedicated DRAM cache
- 1 TB is tight for a large PS5 game library after system reservation
- 1 TB has the smallest SLC write cache in the line
- Costs more than the bare NN4LE for PC-only use
- Limited Western retail availability


## Verdict

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.

## Frequently Asked Questions

### Is the Nextorage NEM-PAB compatible with the PlayStation 5?

Yes. Nextorage lists the NEM-PAB as tested for compatibility with the PS5, PS5 Slim, and PS5 Pro. It is a PCIe 4.0 drive rated 7,400 MB/s, above the console's 5,500 MB/s sustained-read requirement, and it includes a low-profile heatsink sized to fit under the PS5's M.2 expansion cover.

### What is the difference between the NEM-PAB and the NN4LE?

They are the same drive — the same Phison PS5027-E27T controller and Kioxia BiCS6 3D TLC NAND, with identical performance and endurance ratings. The NEM-PAB adds a built-in heatsink and is marketed as PlayStation 5-ready, while the NN4LE (G Series LE) is the bare version intended for PCs that already provide M.2 cooling.

### What controller does the NEM-PAB use?

It uses the Phison PS5027-E27T, a four-channel, DRAM-less PCIe 4.0 controller, paired with Kioxia BiCS6 162-layer 3D TLC NAND. This was confirmed in third-party review coverage. It uses the host memory buffer instead of on-board DRAM and reaches the full PCIe 4.0 read ceiling of around 7,400 MB/s.

### Is 1 TB enough for a PlayStation 5?

1 TB adds meaningful space, but after the PS5's system reservation the usable capacity holds only a handful of the largest modern games. For a single rotation of current titles it is workable; for a large permanent library, the 2 TB or 4 TB NEM-PAB is a better fit. The drive can be added alongside the console's internal storage.

### What is the TBW endurance of the NEM-PAB 1 TB?

The 1 TB model is rated for 600 TBW (terabytes written) with a 1,500,000-hour MTBF and a 5-year warranty, whichever comes first. Console gaming writes relatively little, so the endurance ceiling is effectively unreachable within the warranty period — at 30 GB written per day it would take about 54 years to reach 600 TBW.
