Reviewer verdict

Across 10 YouTube reviews, the SP (Silicon Power) SP UD90 earns a Summa score of 4.3/5, ranking #12 among SSDs. Reviewers most often praise its performance, price, features, while the most common criticisms concern performance, capacity.

The SP UD90 is widely praised for its strong performance, with reviewers (32 mentions) repeatedly noting fast read/write speeds, consistent sustained writes, and excellent real-world and synthetic results. Many comments highlight its SLC caching and LDPC support as contributors to high sequential and random performance, and multiple reviewers call it 'insanely fast' or the fastest M.2 drive they've tested. Reviewers also frequently cite value (11 mentions), calling pricing good or affordable and pointing to strong performance-for-price. Additional recurring positives include useful features like low-profile heatsinks, MagSafe/USB-C connectivity, broad compatibility, and a 5-year warranty noted by some.

Criticisms are fewer but consistent: several reviewers (6 mentions) say the generational performance gap versus Gen4 is small and read speeds can fall short of specifications, producing underwhelming gains for some workloads. Capacity and formatting issues were noted by a few (3 mentions), including sizable onboard usage and the need to format for certain devices, and form-factor/thermal caveats appear (2–3 mentions) — the heatsink can be hard to remove and the drive may be unusable with cramped motherboard M.2 layouts or large motherboard heatsinks. A couple of reviewers also point out the general heat generation of M.2 devices.
