Silicon Power 500GB UD90 NVMe 4.0 Gen4 PCIe M.2 SSD R/W up to 5,000/2,700 MB/s (SP500GBP44UD9005)

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.

Great product at a great price. Ran multiple tests with my Mac Studio: Black Magic Disk Speed Test; Amorphous DiskMark, AJA System Test. All using an OWC thunderbolt enclosure rated at 3000. MBps. All 3 tools showed Write/Read performance at 3000 MBps.See pictures on speed test results.Make sure to marry this with TB enclosure and cable.

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.

The performance of this NVMe inside a $23 Sabrent enclosure impressed me quite a bit. I was getting at least a GB a second - which was nice. No, I did not use a benchmarking tool - this is just me watching the files fly.

Muy buena memoria, llega a los 3500 mbs de escritura y de lectura. Mover archivos a esta nueva memoria fue muy rápido de hacerlo. La instale en una laptop lenovo legion 5 2021 y sin ningún problema.

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.

Ordered this because I just wanted a cheap 3rd SSD in my PC so I could tinker with Linux distros. So far so good.
