Reddit take
AI summary of the Reddit excerpts below — not a quote
The Silicon Power UD90 is a widely recommended budget PCIe 4.0 NVMe SSD, frequently cited as a significant performance upgrade over SATA drives and SSHDs for entry-to-mid-level builds. While it is praised for its price-to-performance ratio, it is a common subject of debate regarding its hardware components, specifically its use of QLC flash and lack of a dedicated DRAM cache.
Pros
- Excellent value for a PCIe 4.0 drive in budget-conscious builds
- Substantial speed improvement over older 2.5-inch SATA SSDs and SSHDs
- Frequently recommended as a reliable alternative to more expensive mainstream brands
- Capable performance for general gaming and standard desktop use
Cons
- Uses QLC flash, which some users associate with lower long-term durability and slower speeds as the drive ages
- Lacks a dedicated DRAM cache, making it less ideal for sustained write-heavy tasks
- Performance may become noticeably slower after several years of use according to some community members
Caveats
- There is community uncertainty regarding whether this drive or competitors like the TeamGroup MP44L offer better support for Linux
- Hardware specifications (like flash type) are a primary point of contention for users prioritizing longevity over initial cost
Best for
- Budget-focused gaming PC builds
- General storage and OS booting for casual users
- Replacing mechanical hard drives or older SATA SSDs
Avoid if
- Professional video editing or other write-intensive workloads that require a DRAM cache
- Users who prioritize high-durability TLC flash over QLC for long-term peace of mind
