Don't Buy Samsung 990 Pro NVMe SSD Before You See This [2026]
Critical warnings about firmware issues, high price, and better alternatives you need to know.
Before You Buy...
Before you spend over $200 on the Samsung 990 Pro, there's something Samsung won't tell you. Thousands of buyers discovered a firmware bug that could kill their drive within months. Here's what you need to know and which SSDs actually deliver real value.
The Samsung 990 Pro is one of the most hyped NVMe SSDs on the market, boasting blazing fast read/write speeds and a trusted brand name. But hidden beneath the marketing are serious issues that early adopters learned the hard way. From a notorious firmware bug that causes rapid health degradation to a premium price that doesn't always justify the performance, the 990 Pro isn't the slam dunk it appears to be. In this guide, we'll reveal the hidden costs, compatibility pitfalls, and common mistakes buyers make, plus suggest better alternatives that save you money and headaches.
🔍What They Don't Tell You
Samsung doesn't advertise that the 990 Pro had a widespread firmware issue (since fixed with newer firmware, but older drives may still be affected) that caused the drive's health to drop precipitously—sometimes to 80% in just weeks of light use. Many users only discovered this after checking their drive's SMART data. Additionally, the 990 Pro's performance, while impressive in benchmarks, can throttle under sustained writes, making it less ideal for heavy workstation use. Samsung also doesn't highlight that you may need a PCIe 4.0 motherboard and a BIOS update to get full performance, and that the heatsink version is required for PS5 use but adds cost.
⚠️Critical Warnings
⚠️Firmware Bug Causes Rapid Health Degradation
IMPORTANTA significant number of Samsung 990 Pro drives shipped with a firmware bug that caused the SSD to report drastically reduced health (SMART attribute) after minimal use. Users reported health dropping to 80-90% within weeks, far faster than expected. Samsung has released a firmware update to address this, but not all drives may have the fix pre-installed, and applying the update can be a hassle for non-technical users. This bug can lead to premature drive failures and data loss if not addressed.
Affects: Most buyers
⚠️High Price Compared to Competitors with Similar Performance
IMPORTANTThe Samsung 990 Pro often commands a $20-50 premium over comparable SSDs like the WD Black SN850X or SK Hynix Platinum P41, while offering nearly identical real-world performance. Benchmark differences are negligible for most users, making the extra cost hard to justify.
Affects: Most buyers
⚠️Requires PCIe 4.0 Motherboard and BIOS Update for Full Speed
IMPORTANTThe 990 Pro is a PCIe 4.0 drive, but many users install it on older PCIe 3.0 motherboards, which limits speeds to around 3500 MB/s—similar to much cheaper drives. Even on PCIe 4.0 motherboards, some BIOS versions may not correctly negotiate Gen4 speeds without an update. This is not mentioned prominently in product listings.
Affects: Most buyers
⚠️Heatsink Not Included in Standard Version
IMPORTANTThe base model of the 990 Pro does not include a heatsink. For sustained high-performance workloads or use in a PS5 (which requires a heatsink), you must buy the more expensive 'with Heatsink' variant or purchase a third-party heatsink. This adds $10-30 to the total cost.
Affects: Most buyers
⚠️Samsung Magician Software Can Be Intrusive
IMPORTANTSamsung's Magician software is required for firmware updates and health monitoring, but it runs background processes, collects usage data, and sometimes forces updates. Some users have reported performance impacts or privacy concerns. Alternatives like CrystalDiskInfo are simpler and don't require account registration.
Affects: Most buyers
⚠️No PCIe 5.0 Support for Future-Proofing
IMPORTANTThe 990 Pro is a Gen4 SSD. With PCIe 5.0 drives becoming more common (e.g., Crucial T700, Samsung 9100 Pro upcoming), the 990 Pro won't take advantage of faster Gen5 slots. If you plan to keep your system for 5+ years or do heavy sequential workloads, a Gen5 drive may be a better long-term investment.
Affects: Most buyers
⚠️Performance Throttling Under Sustained Loads
IMPORTANTWhile the 990 Pro performs well in burst writes, under sustained large file transfers (e.g., video editing, content creation) performance can drop due to thermal throttling or dynamic SLC cache depletion. This makes it less ideal for professional workstation use compared to drives with better sustained write performance like the Seagate FireCuda 540.
Affects: Most buyers
💸Hidden Costs
- 💰Heatsink purchase required for PS5 or sustained workloads ($10-30 extra).
- 💰Potential need for PCIe 4.0 compatible motherboard if upgrading from older system.
- 💰Samsung Magician software bloat and optional account registration.
- 💰Higher initial price compared to equivalent performance competitors ($20-50 premium).
- 💰Cost of aftermarket thermal pad or heatsink if not compatible with built-in motherboard heatsink.
🚫Common Mistakes Buyers Make
- ❌Buying the standard version for PS5 without checking that a heatsink is required.
- ❌Installing on a PCIe 3.0 motherboard and expecting Gen4 speeds.
- ❌Not updating firmware immediately to avoid the health degradation bug.
- ❌Paying extra for the 990 Pro when a cheaper SK Hynix P41 or WD SN850X offers same real-world performance.
- ❌Assuming the drive comes with cloning software (does not; need Samsung Data Migration separately).
- ❌Overlooking that the 990 Pro is overkill for typical gaming or general use.
🔌Compatibility Issues
- ⚡Requires PCIe 4.0 slot for full performance; PCIe 3.0 slots limit speed to ~3500 MB/s.
- ⚡PS5 requires the heatsink version and may need a firmware update for stability.
- ⚡Some older motherboards (e.g., B450/X470) need BIOS update to recognize Gen4 SSDs correctly.
- ⚡Samsung Magician does not work on Linux or macOS; no alternative cross-platform tool for firmware updates.
- ⚡Potential incompatibility with certain laptop cooling designs if the drive runs hot.
- ⚡PCIe 4.0 lanes may be shared with other components (e.g., GPU) on some motherboards, reducing bandwidth.
🌟Better Amazon Alternatives

📝Bottom Line
The Samsung 990 Pro is a capable PCIe 4.0 SSD, but it's not the undisputed king it's marketed to be. Between the past firmware health bug, premium pricing, and strong competition, most buyers are better off with alternatives like the WD Black SN850X (best overall for gaming) or SK Hynix Platinum P41 (best value). If you must have the Samsung name, update the firmware immediately upon installation. For PS5, consider the SN850X with heatsink or the Crucial T500 to save money. Avoid the 990 Pro if you're on a tight budget or don't need top-tier benchmark numbers. Read reviews and compare prices before pulling the trigger.
