# Nextorage NN4LE 2 TB: the sweet-spot DRAM-less PCIe 4.0 G Series LE (2026)

The Nextorage NN4LE 2 TB is a PCIe 4.0 x4 NVMe SSD from the G Series LE line, built on the Phison PS5027-E27T controller with Kioxia BiCS6 3D TLC NAND and a host-memory-buffer design, rated 7,400 MB/s reads and 6,400 MB/s writes with 1,200 TBW of endurance and a 5-year warranty.

Quick answer: The Nextorage NN4LE 2 TB is the pick of the G Series LE line: the efficient Phison E27T controller, current Kioxia BiCS6 TLC NAND, the full 7,400 MB/s read ceiling, a higher write rating and larger SLC cache than the 1 TB, and a 5-year warranty with 1,200 TBW endurance.

## Performance

The NN4LE 2 TB is rated at 7,400 MB/s sequential reads and 6,400 MB/s sequential writes over PCIe 4.0 x4, with 1,000,000 random read IOPS and 950,000 random write IOPS. The higher write rating versus the 1 TB reflects the greater NAND parallelism at this capacity.

The DRAM-less HMB design keeps heat and power low, so the bare drive runs comfortably with basic airflow. The 2 TB's larger SLC write cache absorbs more of a big transfer before throughput settles to native TLC speed, giving it noticeably better sustained write behaviour than the 1 TB. For gaming, large installs, and everyday desktop work, the NN4LE 2 TB performs close to DRAM-equipped Gen4 drives in the tasks that matter.

## Endurance, TBW & Warranty

Nextorage covers the NN4LE with a 5-year warranty. The 2 TB model is rated for 1,200 TBW (terabytes written) and an MTBF of 1,500,000 hours, with coverage ending at whichever limit comes first: five years from purchase or 1,200 TBW of cumulative writes.

At a typical 30 GB of writes per day, reaching 1,200 TBW would take well over a century, so the 5-year term is the only practical limit. Even at a sustained 100 GB per day, the endurance rating spans about 32 years. For desktop and gaming workloads the TBW ceiling is not a real consideration; the warranty length is the binding factor.

## Pros and Cons

**Pros:**

- Full 7,400 MB/s PCIe 4.0 reads with 6,400 MB/s writes
- Larger SLC cache and better sustained write than the 1 TB
- Current Kioxia BiCS6 162-layer 3D TLC NAND
- 1,200 TBW endurance with a 5-year warranty
- Efficient DRAM-less design runs cool
- Single-sided M.2 2280 fits laptops and compact builds
**Cons:**

- DRAM-less (HMB) — no dedicated DRAM cache
- Ships bare — needs a separate heatsink for PlayStation 5 use
- Write IOPS (950,000) slightly below read
- Limited Western retail availability
- DRAM-equipped Gen4 rivals can hold higher sustained mixed-workload consistency


## Verdict

The Nextorage NN4LE 2 TB is the pick of the G Series LE line: the efficient Phison E27T controller, current Kioxia BiCS6 TLC NAND, the full 7,400 MB/s read ceiling, a higher write rating and larger SLC cache than the 1 TB, and a 5-year warranty with 1,200 TBW endurance.

It is a strong 2 TB Gen4 drive for a desktop or laptop that wants fast, cool-running mainstream storage with room for a game library. Buyers who want this drive in a PlayStation 5 should choose the heatsink-equipped NEM-PA version, and those needing maximum capacity can step up to the 4 TB NN4LE.

## Frequently Asked Questions

### What controller and NAND does the NN4LE 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 E27T reaches the full PCIe 4.0 sequential ceiling of around 7,400 MB/s while remaining efficient.

### Is the NN4LE 2 TB better than the 1 TB?

Yes, for most buyers. The 2 TB adds capacity, a higher write rating (6,400 vs 6,100 MB/s), a larger SLC write cache for better sustained performance, and double the endurance (1,200 vs 600 TBW), usually at better cost-per-gigabyte. The 1 TB is the lower-cost entry point if you do not need the space.

### Can the NN4LE 2 TB be used in a PlayStation 5?

It is a compatible PCIe 4.0 drive, but it ships bare and the PS5 requires a heatsink for M.2 expansion drives, so you would need to add one. Nextorage's NEM-PA series is the same drive sold with a heatsink and is the intended drop-in PS5 option.

### Does the NN4LE 2 TB have a DRAM cache?

No. It is DRAM-less and uses the host memory buffer (HMB). Paired with the efficient Phison E27T and Kioxia BiCS6 NAND, real-world performance is close to DRAM-equipped Gen4 drives for typical gaming and desktop use, while keeping power and heat low.

### What is the TBW endurance of the NN4LE 2 TB?

The 2 TB model is rated for 1,200 TBW (terabytes written) with a 1,500,000-hour MTBF. The 5-year warranty covers whichever comes first: five years or 1,200 TBW. At 30 GB written per day it would take more than a century to reach 1,200 TBW, so the warranty period is the practical limit, not the endurance rating.
