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
Description
Don't lose your train of thought with slow load times! Designed with content creators in mind, the UD90 is built to handle the demanding levels of multi- tasking that's required of creative production, effortlessly. With support for NVMe 1.4 and Host Memory Buffer (HMB) technology, the UD90 offers uninterrupted productivity via higher performance and lower latency for seamless execution across applications.

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.

This M.2 NVMe SSD is one I heavily rely on for all of my builds. The 2TB drive is amazing for the money. It is always super easy to install and fits everytime. It even works with Gen 3x4 M.2 slots so whenever you choose to upgrade your motherboard, you can use it on the next one. It is also very fast to fit all of your games on with fast game boot times.

The Silicon Power 2TB UD90 NVMe Gen4 SSD is a beast! With read/write speeds of up to 5,000/4,800 MB/s, this drive is insanely fast. Boot times, game loading, and file transfers are all lightning quick now. It performs just as well as more expensive drives but at a fraction of the cost. Installation was simple—plug and play with no issues. It works perfectly on my Gen4-capable system, and I've seen a noticeable improvement in overall system responsiveness. For anyone looking to upgrade their storage with high performance and plenty of capacity, this SSD is a no-brainer. Highly recommend!

4TB SSD. Great product at a great price. I am using it in PS5 and its working great and very fast. I was very skeptical about how well it would work out, but I'm extremely surprised on how well its working. Its very easy to install and use. Its great for games on the PS5. Thank you so much to the seller. Great job and great product.

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.

I’ve been using the Silicon Power UD90 2TB NVMe Gen4 SSD for a few weeks, and overall, it's a fantastic value. Speeds are solid for a Gen4 drive — fast boot times and snappy file transfers, easily hitting advertised numbers in real-world use. While it's not quite top-tier like Samsung or WD Black in sustained performance under heavy load, it holds its own for most tasks including gaming, photo editing, and general use. Thermals are decent with a heatsink, and installation was easy. If you’re upgrading from a SATA SSD or Gen3 NVMe, you’ll notice a big jump. For the price, it’s hard to beat. I knocked off one star only because the endurance rating is average and software support is minimal.

I bought this product because my 2TB M2 SSD was getting full. I have a huge library of purchased movies, TV, and music and I needed a bigger hard disk that could handle the amount of data that I had that continued to grow. The load times are incredibly fast. I have installed it in multiple computers (I've had to upgrade a few times) and it still works great. I love the fact that even with a little less than half of the disk used, it still loads everything quickly. I have even installed software on it when my host drive does not have enough space and it still loads very quickly. Definitely worth every penny I paid for it.
