Transcend MTE255S 1TB PCIe Gen4 NVMe SSD
1TBPCIe Gen4 x4 NVMeUp to 7,400MB/sM.2 2280 · Graphene Heatsink
The Transcend MTE255S 1TB, part number TS1TMTE255S, is a value-focused PCIe Gen4 internal M.2 2280 NVMe SSD with an integrated graphene heatsink, designed for the PlayStation 5, desktops and laptops. With sequential reads up to 7,400MB/s, it offers near top-tier Gen4 speed while the slim graphene layer keeps temperatures in check without adding bulk — ideal as a fast, affordable boot or game drive.
Delivering sequential reads up to 7,400MB/s and writes up to 5,200MB/s, the MTE255S handles gaming and everyday tasks with ease. Carrying EAN 0760557870890 and MPN TS1TMTE255S, it uses 3D TLC NAND in a single-sided DRAM-less design with LDPC error correction, a 600TBW endurance rating and a 5-year limited warranty. Typically in stock with fast delivery across Cyprus.
Compatibility note
The MTE255S uses the standard M.2 2280 size (22 x 80mm) with a PCIe NVMe slot, and is single-sided. Its thin graphene heatsink fits the PlayStation 5’s storage bay and most laptops and desktops — unlike thick metal heatsinks, it stays slim enough for handhelds and notebooks. It runs at full speed in Gen4 slots and works in Gen3 slots at reduced speed.

Frequently Asked Questions
Does it work in a PS5 without a separate heatsink?
Yes — the MTE255S has an integrated graphene heatsink and meets the PS5’s speed requirement, so it fits the console’s storage bay and you do not need to buy a separate metal heatsink.
Will the graphene heatsink fit in a laptop?
In most cases, yes. The graphene layer is very thin — far slimmer than a metal heatsink — so it usually fits laptops and slim systems where a thick heatsink would not. Check your device clearance to be sure.
How fast is it compared to top Gen4 drives?
Very competitive — up to 7,400MB/s reads put it near the top of the Gen4 class. As a DRAM-less drive it can trail premium DRAM models in sustained heavy writes, but for gaming and everyday use the difference is minimal.
Is it suitable as a boot drive?
Yes. It works well as a fast boot and storage drive in a Gen4 PC, giving quick system startup and application loading along with 1TB of capacity for games and files.
Singular Expert Insight
The Transcend MTE255S 1TB hits a sweet spot for PS5 owners and budget Gen4 builders: it reaches up to 7,400MB/s, includes a slim graphene heatsink that fits the console out of the box, and costs less than premium DRAM drives. It is DRAM-less, so a high-end drive like the Samsung 990 PRO holds an edge in sustained heavy workloads, but for gaming and general use the MTE255S is hard to beat on value. The thin heatsink is also a real plus for laptops where chunky metal coolers will not fit. Explore the full range in our

Buyer's Guide
Buy it if
You want a fast, PS5-ready 1TB Gen4 drive with a slim built-in heatsink and up to 7,400MB/s, at a great value price with a 5-year warranty.
Skip it if
You need a DRAM-equipped drive for sustained professional write workloads, or PCIe Gen5 speeds for a Gen5-ready desktop.
Also consider
The Samsung 990 PRO for top-tier Gen4 with DRAM, or the 2TB MTE255S if you need more capacity for a larger library.
