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

    • Blazing Fast and Great Value!
Capacity: 2 TB Style: Standard
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! ... show more

    • 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.

    • Great performance for the money. Love the 4TB capacity.
Capacity: 4 TB Style: Standard
Had it plugged in and running in about 2 min. 7GB read and about 4.5GB write. Fast enough for me! Tried some really long writes and it dipped to 500MB/sec once in a while but not less than that. That tells me that it's probably TLC nand and not QLC (I was a little worried about that cause I couldn't confirm). I know the 2TB and smaller are all TLC so logically the 4TB should be also but wasn't 100% sure. Hit a max. of 60 degrees C (140 F) so that's not too bad. It sure feels nice to have a 4TB drive that is FAST!......and doesn't cost an arm and a leg. It's great to see SSD prices coming way down in the last several months. SP is not a top brand but I've never had a problem with any of the dozen or so components I've purchased over the last 5 or 6 years so I've gotten to trust them. They tend to offer comparable performance at significantly lower cost. So far I'm really happy with this SSD and highly recommend it. ***Update*** It's now a few months later and I thought I would add a little more information. I bought a Beelink SER6 miniPC recently. It came with a bottom-of-the-barrel 512GB QLC SSD (slow and hot). I wanted to upgrade it right away as I had a few other (much better) SSD's kicking around. I tried 2 of them but they would NOT fit - too thick. The 4TB UD90 was PERFECT. It is single sided and very thin. The fact that there is very limited room in this PC so that you cannot even install a decent heat sink, makes it imperative that the SSD runs fairly cool. The UD90 does that along with great speed so it was the perfect upgrade for my new mini computer. So glad I hadn't already set it up for another purpose. So, if you need a great priced, fast SSD to install in tight spaces this is the perfect choice. ... show more

    • ⭐⭐⭐⭐⭐ Great SSD for External Enclosures — Works Perfectly With My Mac mini M4

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. ... show more
