2TBPCIe Gen4 x4 NVMeUp to 5,000MB/sM.2 2280 · Value
The Silicon Power UD90 2TB, part number SP02KGBP44UD9005, is an affordable PCIe Gen4 internal M.2 2280 NVMe SSD aimed at value-conscious upgrades for desktops and laptops. With sequential reads up to 5,000MB/s and a generous 2TB capacity, it delivers a clear, budget-friendly step up from SATA SSDs and hard drives for everyday computing, gaming and storage.
Reaching sequential reads up to 5,000MB/s and writes up to 4,800MB/s, the UD90 keeps your system responsive. Carrying EAN 0886576067612 and MPN SP02KGBP44UD9005, it uses 3D NAND with SLC caching and LDPC error correction in a DRAM-less HMB design, has a 1.5 million-hour MTBF, a 1,200TBW endurance rating and a 5-year limited warranty. Typically in stock with fast delivery across Cyprus.
Compatibility note
The UD90 uses the standard M.2 2280 size (22 x 80mm) with a PCIe NVMe slot, and fits the vast majority of laptops and desktops. It runs at full speed in Gen4 slots and works in Gen3 slots at reduced speed. It will not fit SATA-only M.2 slots. For PS5 use, a separate heatsink is required and its Gen4 speed meets the console’s minimum.

Frequently Asked Questions
Will it 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 much faster is it than a SATA SSD?
Noticeably faster — up to 5,000MB/s versus around 550MB/s for SATA. You will see quicker boots, faster loads and much faster large-file transfers, for an affordable price.
Is it as fast as a premium Gen4 drive?
No — top Gen4 drives reach around 7,000MB/s. The UD90 prioritises value at up to 5,000MB/s, which is still a big upgrade over SATA and plenty for everyday use and gaming.
Can I use it in a PS5?
Yes, its Gen4 speeds meet the PS5’s minimum requirement, but you must add a compatible M.2 heatsink, as one is not included. Premium drives are faster, but the UD90 works for budget expansion.
Singular Expert Insight
The Silicon Power UD90 is a sensible budget Gen4 drive: at up to 5,000MB/s it is not the fastest, but it comfortably beats any SATA SSD and offers a roomy 2TB at a keen price, making it a great value upgrade for a laptop or everyday desktop. As a DRAM-less drive it relies on SLC caching, so very heavy sustained writes are better suited to a premium TLC drive with DRAM, like the Samsung 990 PRO. For typical computing, gaming and storage on a budget, the UD90 delivers a lot of capacity and speed for the money. Browse the full range in our

Buyer's Guide
Buy it if
You want an affordable 2TB NVMe upgrade that clearly beats SATA for everyday computing, gaming and storage, with a 5-year warranty.
Skip it if
You want maximum Gen4 speed (around 7,000MB/s), a DRAM drive for heavy sustained writes, or PCIe Gen5 performance.
Also consider
The Kingston NV3 for another value Gen4 drive, or the Samsung 990 PRO / WD_BLACK SN850X for top-tier Gen4 performance.
