NVMe Gen4 Pro

7,400 MB/s.
More spreader.

Identical link ceiling to the standard Gen4 drive. The difference is thermal headroom: a full-module graphene spreader has more area and mass than a 0.5 mm label, so sustained sequential writes take longer to reach the throttle point. That matters in a bare M.2 slot with no motherboard shield and poor airflow — and nowhere else.

Engineering notes

One difference,
and where it matters.

Identical link ceiling

7,400 MB/s read, 6,600 MB/s write, PCIe 4.0 ×4 — about 94% of the 7.88 GB/s the link can carry. Same ceiling as the standard Gen4 drive, because the link is the ceiling.

Thermal mass, not speed

The difference is a graphene spreader across the full module rather than a 0.5 mm label. More area and more mass means the controller reaches its throttle point later during sustained sequential writes. It does not raise peak speed by a single MB/s, and it does not extend the SLC cache.

When it is worth paying for

A bare M.2 slot with no motherboard shield and poor case airflow. A drive that spends long stretches writing — video ingest, backup targets, game library moves. If your board ships an M.2 heatsink shield, that shield is already the heat path and this spreader adds very little; take the standard Gen4 drive instead.

Still low-profile

Despite the extra spreader it remains inside the PS5 M.2 bay envelope and fits laptop M.2 slots. That is the line between this and the Gen5 drive, whose machined heatsink rules both out.

SLC cache behaves the same

3D TLC with an SLC-mode write buffer. Past the cache, native TLC program speed applies on this drive exactly as on any other. Keep 10–15% free space if sustained writes are your workload.

Undocumented rows stay undocumented

Controller part and DRAM buffer configuration are not published by the supplier, so this page does not state them. We confirm on the batch rather than copy a spec sheet from a different SKU.

Specifications

Drive configuration
Form factorM.2 2280, M-key, NVMe 1.4 over PCIe 4.0 ×4
Capacities512 GB / 1 TB / 2 TB
Sequential readUp to 7,400 MB/s — PCIe 4.0 ×4 is 16 GT/s aggregate, about 7.88 GB/s usable, so this is roughly 94% of the link ceiling
Sequential writeUp to 6,600 MB/s — into SLC-mode cache. Past it, native TLC program speed applies; the extra spreader area delays thermal throttling, it does not extend the cache.
NAND3D TLC — three bits per cell, with a portion run in SLC mode as a write cache. Controller part and whether a DRAM buffer is fitted are not stated in the supplier documentation; we do not claim a DRAM cache we have not verified.
CoolingGraphene spreader over the full module. More area and mass than a label, still low enough for the PS5 bay envelope and laptop M.2 slots. Under a motherboard M.2 shield it gains little — the shield is already the heat path.
Platform support & assurance
FitsAny M-key M.2 2280 NVMe slot. In a Gen3 ×4 slot it links at Gen3 and tops out near 3,500 MB/s — the drive is not faulty, the link is the limit. PS5 storage expansion: yes, Sony requires ≥5,500 MB/s read and this exceeds it.

Compare with NVMe Gen4

Before you order.

NVMe Gen4Same 7,400 MB/s with a 0.5 mm label. The right one when the slot already has a motherboard shield. NVMe Gen510,000 MB/s and a DRAM cache, but only in a CPU-attached Gen5 slot — and its heatsink rules out PS5 and laptops. How we testLink speed check, SMART read, sequential and random pass. And what happens to the drives that fail. Ask before you paySend the board or laptop model and we confirm the slot is NVMe, not SATA, and what it links at.
