Features 4
- 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
Description
Give your system the power of PCIe 4.0 with the budget-friendly UD90. Providing the best bang for your buck, it reaches read speeds up to 5,000MB/s and write speeds up to 4,500MB/s. It also boasts 2x faster data transfer rates than its predecessor, PCIe 3.0, for sustained use and dependable performance. With this much efficiency, the UD90 allows you to maximize your creative output at an unbeatable value.

One of My Go To Budget SSDs
Capacity: 1 TB
Style: Standard
With SSD prices being higher lately, the Silicon Power UD90 has consistently been one of the best budget options I have found. It is commonly ranked as a mid tier SSD, but in my experience it performs extremely well. I build PCs as a side business and have purchased and installed dozens of these drives. So far, I have not had any problems with them. They provide fast performance, plenty of storage for gaming, and excellent value for the price. For anyone new to PC building, even an entry level NVMe SSD is much faster than an older mechanical hard drive. Unless you are regularly transferring very large files or doing specialized professional work, buying the absolute fastest SSD usually does not make much difference for normal gaming. For a gaming PC or everyday system, this drive should be everything most people need. It has become one of my go to SSDs because it performs well, has been reliable, and is usually priced competitively.

⭐⭐⭐⭐⭐ Great SSD for External Enclosures — Works Perfectly With My Mac mini M4
Capacity: 2 TB
Style: Standard
I’m using the Silicon Power UD90 2TB inside a VANGREE 80Gbps NVMe enclosure connected to my Mac mini M4, and it has been rock‑solid. Even though this drive is rated for up to 5,000/4,800 MB/s on PCIe Gen4, real‑world speeds over Thunderbolt4 land right around 3,000 MB/s, which is exactly what you should expect from an external setup. No throttling, no disconnects, and no heat issues so far. Installation was simple, and the drive was immediately recognized by macOS. I formatted it as APFS and have been using it for apps, large files, and video exports without any slowdown. The UD90 runs cooler than many Gen4 drives I’ve tested, which makes it a great match for compact enclosures. Fun fact: macOS actually recognized this drive as 2.05TB, which means I’m getting slightly more usable space than advertised. Most SSDs report less usable capacity, so this was a pleasant surprise. For the price, performance, and reliability, this SSD is an excellent choice if you’re planning to use it externally with a Mac mini M4, MacBook, or any Thunderbolt/USB4 device. Great value and highly recommended.

Works perfect
Capacity: 1 TB
Style: Standard
Works great, I ordered this on July 31st of 2025 and there has never ever been any problems for me with it, I have it on my PlayStation and it worked, when I was installing it I was shaking but it was obviously my first time so if you have experience then do it without tutorials, If you don’t then I recommend watching videos, over all I give a 10/10 for the peformance.

Works Well- Has Suspected Issue - Likely my fault
Capacity: 2 TB
Style: Standard
Suspected drive failures. 100% Utilization on bootup, for minutes, with very little data transfer. Will revise rating upward if customer service handles this appropriately. Update: Turn out the suspected issue is likely bad partitioning and lack of free space for windows.

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.

It works

Apart from being packaged like a dollar store toy, I found this card to be just as good as any others I've used. Maybe Amazon should be putting these in some type of padded box or mailer and not haphazardly in a box with 10 other big heavy items.

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.
