MSI SPATIUM M450 1TB PCIe Gen4 NVMe SSD
1TBPCIe Gen4 x4 NVMeUp to 3,600MB/sM.2 2280
The MSI SPATIUM M450 1TB, part number S78-440L0M0-P83, is a cost-effective PCIe Gen4 internal M.2 2280 NVMe SSD designed for mainstream desktops and laptops. From MSI’s SPATIUM storage line, it delivers a solid step up from SATA SSDs and hard drives at an accessible price, using 3D NAND flash and the efficient Phison E19T controller — an easy, affordable way to add fast storage.
With sequential reads up to 3,600MB/s and writes up to 3,000MB/s, plus random performance up to 420K/550K IOPS, the M450 makes a responsive boot and storage drive. Carrying EAN 4711377294454 and MPN S78-440L0M0-P83, this DRAM-less (HMB) model is rated for 600 TBW and is backed by a 5-year limited warranty. Typically in stock with fast delivery across Cyprus.
Compatibility note
The M450 needs an M.2 2280 slot — 22mm wide and 80mm long — with an NVMe PCIe key. It works in PCIe Gen4 and Gen3 slots (at the slot’s speed) and fits most recent laptops and desktops. It will not work in SATA-only M.2 slots.

Frequently Asked Questions
Will the M450 fit my laptop or desktop?
It uses the standard M.2 2280 size with an NVMe PCIe slot, which fits most laptops and desktops from the last several years. Check your manual for an "M.2 2280 PCIe/NVMe" slot before buying.
How fast is it compared with a SATA SSD?
Noticeably faster — up to 3,600MB/s versus around 550MB/s for SATA. You will see quicker boots, faster loads and snappier file transfers, making it a great-value upgrade from a SATA drive or hard disk.
Is it as fast as a high-end Gen4 SSD?
No — at 3,600MB/s the M450 is a mainstream Gen4 drive, about half the peak speed of flagship 7,000MB/s models. For everyday use, gaming and general storage the difference is minimal, and the M450 costs much less.
What does DRAM-less mean here?
The M450 uses Host Memory Buffer instead of an onboard DRAM cache, borrowing a little system RAM for its mapping table. For typical use the real-world impact is small, and it keeps the drive affordable and efficient.
Singular Expert Insight
The MSI SPATIUM M450 is a sensible value pick: a mainstream Gen4 drive that comfortably beats any SATA SSD while staying affordable, backed by a reassuring 5-year warranty. The 1TB is a great everyday boot-and-storage size. Its peak speeds sit below flagship Gen4 drives, and its DRAM-less design means a higher-end model like the Samsung 990 PRO holds up better under sustained heavy writes — but for everyday computing and gaming the M450 feels quick for far less.

Buyer's Guide
Buy it if
You want an affordable 1TB Gen4 NVMe upgrade for a desktop or laptop that comfortably beats SATA, for everyday computing and gaming, with a 5-year warranty.
Skip it if
You want maximum Gen4 speed (flagship drives are roughly twice as fast), or you do sustained heavy writes where a TLC, DRAM drive holds up better.
Also consider
The Crucial P310 or Kingston NV3 for similar value, or the Samsung 990 PRO / Lexar NM790 for full-speed Gen4 performance.
