SP01KGBP44UD90051TB1TB 5-year limited warranty

Solid State Drives

Large 69 GB SLC cache provides burst speeds over 4.6 GB/s for short write workloads, improving overall responsiveness.

✓600 TBW endurance and a 5‑year warranty give confidence in long‑term reliability for everyday use.

✓Compact single‑sided M.2 2280 and 2230 options allow installation in thin laptops and handheld devices.

Cons

✗After the SLC cache is exhausted, sustained write speeds drop to around 1.8 GB/s and eventually to about 275 MB/s, limiting heavy write workloads.
✗Being DRAM‑less, random write performance and latency are lower than drives with dedicated DRAM cache, affecting some applications.
✗The 2230 variant has lower advertised write speeds (3200 MB/s) and reduced performance in compact devices compared to the 2280 model.
✗No built‑in hardware encryption may be a concern for security‑focused users requiring data protection.
✗Absence of a heatsink option can lead to higher temperatures during prolonged heavy use.

From Expert Reviews

Praised by Experts

✓PC Perspective highlights the drive as an excellent value for PCIe Gen4x4, praising its TLC NAND and 5000/4800 MB/s speeds despite a DRAM‑less controller.
✓Tom's Hardware calls it a new value champion, noting its balanced 69 GB SLC cache, >4.6 GB/s burst performance and high efficiency rivaling premium drives.
✓ServeTheHome points out the 2230 model’s suitability for compact devices like the Steam Deck, emphasizing its 600 TBW endurance and 5‑year warranty.

Criticized by Experts

✗Reviewers note the DRAM‑less architecture leads to noticeable write speed throttling once the SLC cache is depleted.
✗The 2230 version’s conservative write rating (3200 MB/s) and lower random access performance are seen as limitations for demanding tasks.

From User Reviews

Users Love

✓Users report fast boot times and quick game loading on PCIe 4.0 systems, appreciating the performance boost for the price.
✓Positive feedback on low power consumption makes it a popular upgrade for laptops and portable builds.
✓The drive’s large SLC cache is praised for handling typical multitasking and file transfers without stutter.

Users Complain About

✗Consumers mention write throttling after the cache fills, leading to slower sustained transfers.
✗Some users experience higher temperatures during extended workloads due to lack of a heatsink.
✗Random IOPS and latency are reported as lower than expected, affecting certain applications.

Expert Opinion

Professional reviewers consider the UD90 an excellent value proposition for PCIe Gen4x4, applauding its TLC NAND, high sequential speeds and efficient DRAM‑less design, while noting the inevitable write throttling once the SLC cache is exhausted and the modest performance of the 2230 variant for demanding workloads.

What Users Say

Everyday users appreciate the fast boot and game load times, low power draw and the large SLC cache that handles typical multitasking well, but they frequently complain about noticeable write speed drops after the cache fills, higher temperatures without a heatsink, and lower random I/O performance compared to higher‑end drives.

Common Complaints

Write throttling after the SLC cache is depleted, elevated temperatures during prolonged use due to lack of a heatsink, and lower random IOPS/latency compared to DRAM‑equipped SSDs.

How It Compares

vs. Silicon Power FX900 / Inland Platinum P41

Advantages

✓Similar PCIe 4.0 speeds with slightly better burst recovery, offering comparable performance at a similar price point.

Disadvantages

✗Also DRAM‑less, so it suffers from the same write throttling and may have marginally lower sustained write speeds.

Choose the UD90 for better value and endurance; pick FX900/P41 if you prioritize marginally faster burst recovery.

vs. Lexar PLAY (2230)

Advantages

✓Higher advertised sequential speeds (~7000/6000 MB/s) and optimized for handheld devices.

Disadvantages

✗Often uses QLC NAND and may have lower endurance, making it less reliable for long‑term heavy use.

Select Lexar PLAY for maximum raw speed in compact devices, but UD90 offers better endurance and consistent performance.

vs. Solidigm P44 Pro / E12 / E16

Advantages

✓Features dedicated DRAM and higher sustained write performance, suitable for professional workloads.

Disadvantages

✗Higher price and lower value proposition compared to the budget‑focused UD90.

Opt for Solidigm models when you need consistent high write throughput; otherwise the UD90 provides better cost‑efficiency.
