Features

  • To bolster its multi-tasking factor even further, the UD90 takes advantage of increased bandwidth when used in conjunction with motherboards equipped with PCIe 4.0 slots. In fact, it has nearly double the bandwidth of PCIe 3.0 for shorter download times and the ability to download more files within the same amount of time.
  • An SSD's speed is meaningless without the ability to handle that speed reliably. The UD90 achieves improved sequential read/write and random read/write performance with support for SLC Caching. At the same time, it supports low density parity check (LDPC) coding to ensure accuracy of data transmission and reliability of data access.
  • The UD90 supports RAID to protect data in the case of a drive failure. It's also equipped with built-in E2E data protection for enhanced data transfer integrity. Unexpected things can happen at any moment, but the UD90 is prepared for them with your data at its utmost priority.
  • 5-year limited warranty

    • fantastic value
Capacity: 2 TB Style: Standard
I am a huge fan of SP memory and memory products. I have been buying a lot from them recently. I got this because I wanted a decently large primary storage drive for my new main pc. This drive is nice and fast, OS boots in seconds, I haven't had any problems with any of my systems recognizing SP drives or memory. Installation was a snap, and performance was as advertised. I've built a handful of systems both AMD and Intel based and the Silicon Power nvme drives I've been using just work. They don't have to be the very fastest drives out there, but the Gen3 are plenty fast for my needs, even gaming. These are fantastic options that don't cost a ton. ... show more

    • Impressive speed and great capacity
Capacity: 1 TB Style: Standard
The 1TB Silicon Power UD90 surprised me with its speed and stability. Read and write speeds are excellent, and you'll notice the difference immediately when booting up your system or transferring large files. Installation was easy thanks to the M.2 form factor, and the compact design fits perfectly in my PC. Furthermore, it offers a great balance between performance and price, making it an ideal upgrade for improving both everyday use and gaming. ... show more

    • False Advertising: Not TLC but QLC NAND – Incredibly Slow Performance
Capacity: 4 TB Style: Standard
Absolutely, here’s the review rewritten from your perspective, making it clear that you also experienced the slow speeds and recommend staying away from this drive: --- **Avoid This Drive – Slow and Disappointing!** I didn’t personally buy multiple Silicon Power drives in the past, but after seeing detailed reviews and specs, I expected the UD90 to be a decent budget SSD. It’s advertised with a Phison E21T controller and TLC NAND, boasting speeds of 5000MB/s read and 4500MB/s write in SLC mode. On paper, it looked like a solid choice with a 3000TBW rating. However, after putting it to use, I immediately ran into severe slowdowns. Copying large files (about 1TB) exposed just how bad the performance is—sustained writes quickly dropped to an abysmal 150MB/s–250MB/s. Further testing confirmed that the SLC cache is incredibly small (only 15GB–65GB), and once it runs out, the drive slows to a crawl. The controller struggles to flush the cache efficiently, making recovery painfully slow. Benchmarks show that outside of the SLC cache, speeds tank to around 250MB/s for reads and 150MB/s–250MB/s for writes. This strongly suggests the drive is using QLC NAND instead of TLC, which explains the poor sustained performance. QLC not only has lower endurance but also significantly throttles after the cache fills up—impacting both write and read speeds. And for what? To save $10–$20 over a proper TLC drive? Absolutely not worth it. Temperature-wise, it stays reasonable at around 49°C with a heatsink, but that doesn’t make up for the glaring performance issues. If this drive actually used TLC with a proper cache, it could have been a great value option. Instead, it’s a classic case of cutting corners at the cost of real-world usability. I also reached out to Silicon Power’s support to confirm the NAND type and explain the performance problems, but after three days with no response, I decided to dig into the issue myself. In the end, I avoided further frustration and went with a slightly slower but *far* more reliable TLC + DRAM drive (TeamGroup MP34) for just $20 more. If you’re considering this drive—don’t. The performance limitations make it a terrible value, and there are far better options out there. ... show more

    • Good price for performance and honors warranty claim.
Capacity: 4 TB Style: Standard
I purchase this 4TB SP UD90 back in '23. I found the speed adequate for my needs. Worked like a champ until one day it did not. I was using it as a secondary drive for my steam games. Disappeared from BIOS, nothing in disk manager. Well I figure I'd see if SP would honor their warranty and they absolutely did. Went through the RMA process and two weeks later I have a replacement UD90. I purchased another 4TB UD90 and a 2TB 2230 UD90 (For my steam deck.). I'm very please with this company and back it up with my wallet. ... show more
