# Nextorage NEM-PAC 1 TB: PS5-optimised PCIe 4.0 SSD with integrated heatsink (2026)

The Nextorage NEM-PAC 1 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 4,800 MB/s writes with a 5-year warranty.

Quick answer: The Nextorage NEM-PAC 1 TB is a console-first PlayStation 5 drive: the Phison E27T controller and Kioxia BiCS6 TLC NAND of the NEM-PAB, wrapped in an integrated cooling structure tuned for stable performance inside the PS5, with a 5-year warranty.

## Performance

The NEM-PAC 1 TB is rated at 7,400 MB/s sequential reads and 4,800 MB/s sequential writes over PCIe 4.0 x4, with 780,000 random read IOPS and 1,000,000 random write IOPS. The read speed exceeds the PlayStation 5's 5,500 MB/s requirement, so games load at full console speed.

The drive's tuning favours console behaviour: high random write IOPS and a read rating that meets the PS5 spec, with a lower sequential write ceiling than its NEM-PAB sibling. In practice, on a PS5 the difference is invisible during gameplay; it would only surface in large sustained sequential writes, which are rare on a console. The integrated heatsink and cooling structure are designed to hold performance stable during extended sessions inside the PS5's enclosed slot.

## 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 1 TB is estimated at 600 TBW. Coverage ends at whichever comes first: five years or the rated endurance.

Console gaming writes far less than sustained productivity workloads, so endurance is not a practical limit for PS5 use within the warranty period. At a typical 30 GB of writes per day, 600 TBW would take roughly 54 years to reach. The 5-year warranty term is the binding factor.

## Pros and Cons

**Pros:**

- PlayStation 5-optimised with an integrated cooling structure
- 7,400 MB/s reads exceed the PS5's 5,500 MB/s requirement
- High random write rating (1,000,000 IOPS)
- Phison E27T with Kioxia BiCS6 162-layer 3D TLC NAND
- 5-year warranty
- Clean drop-in for a PS5 — no separate heatsink needed
**Cons:**

- Lower sequential write (4,800 MB/s) than the NEM-PAB 1 TB
- 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
- 1 TB is tight for a large PS5 library after system reservation


## Verdict

The Nextorage NEM-PAC 1 TB is a console-first PlayStation 5 drive: the Phison E27T controller and Kioxia BiCS6 TLC NAND of the NEM-PAB, wrapped in an integrated cooling structure tuned for stable performance inside the PS5, with a 5-year warranty.

It is a clean drop-in for a PS5 where its 7,400 MB/s read clears the requirement and the fixed heatsink simplifies installation. The caveats are the lower 1 TB sequential write rating and the non-removable heatsink, which can complicate PC use. Buyers who want higher sequential write at 1 TB, or a drive for a PC M.2 slot with its own cover, should look at the NEM-PAB or bare NN4LE.

## Frequently Asked Questions

### Is the Nextorage NEM-PAC made for the PlayStation 5?

Yes. The NEM-PAC is Nextorage's PlayStation 5-optimised drive, with an integrated, non-removable heatsink and a cooling structure tuned to keep performance stable during long console sessions. It is a PCIe 4.0 drive rated 7,400 MB/s, above the PS5's 5,500 MB/s requirement, and the heatsink fits under the console's M.2 cover.

### Why is the NEM-PAC 1 TB sequential write lower than the NEM-PAB?

The NEM-PAC 1 TB is rated 4,800 MB/s sequential write versus 6,100 MB/s on the NEM-PAB 1 TB, reflecting different firmware tuning, while its random write rating is high at 1,000,000 IOPS. For PlayStation 5 use the difference is not noticeable, as gameplay is read-dominated; it mainly affects large sustained file copies, which are uncommon on a console.

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

Yes, it is a standard PCIe 4.0 NVMe drive and works in a PC M.2 slot. The consideration is the integrated, non-removable heatsink, which may interfere with a motherboard's own M.2 heatsink or cover. For PC use without those clearance issues, the NEM-PAB or bare NN4LE — same controller and NAND — are more flexible options.

### What controller and NAND does the NEM-PAC 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 1 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 1 TB is estimated at 600 TBW, alongside a 5-year warranty and 1,500,000-hour MTBF. Console workloads write far below this, so the warranty term is the practical limit.
