Samsung 990 PRO SSD Review: Speed Champion with Caveats
The Samsung 990 PRO NVMe M.2 PCIe Gen4 SSD has drawn widespread attention for its blistering speed claims and next-gen efficiency. Across multiple platforms, user feedback suggests it is indeed among the fastest PCIe 4.0 drives available, but the narrative isn't entirely without caution — especially for those concerned with reliability history. Overall verdict: 9.2/10, particularly suited to gamers and creative professionals pushing large data loads, with some caveats for budget-conscious buyers.

Quick Verdict
Recommendation: Conditional — exceptional for speed-focused users, but check firmware and cooling setup before purchase.
| Pros | Cons |
|---|---|
| Top-tier sequential speeds (7,450 / 6,900 MB/s) validated by users | Historically reported premature wear issues (now addressed via firmware) |
| Significant random read/write performance boost over 980 PRO | Price premium compared to similar-performing drives |
| Lower power draw for its class, improving laptop battery life | Ships without heatsink in some variants — can run hot under sustained load |
| Reliable under heavy data loads, praised for gaming and creative work | Lower TBW lifespan versus certain competitors |
| Samsung Magician software offers detailed drive management | 4TB model availability can be sporadic |
| Compatible with PS5 and modern desktops/laptops | RGB heatsink only on specific SKUs |
Claims vs Reality
Marketing materials emphasize “up to 55% faster random performance” over the 980 PRO, targeting gamers seeking ultra-fast loading. On Reddit, PC builders and PS5 upgraders confirm title screens and level transitions often feel near-instant — one PCPartPicker user noted Forspoken maps loading “in about a second,” versus 28 seconds on HDD.
Samsung further promotes a “50% improved performance per watt.” Laptop users on Twitter and Quora back this up, reporting cooler operation and extended unplugged usage. This efficiency particularly appeals to mobile 3D animators and video editors working on long flights, where less heat translates to quieter fans.
The brand also claims “smart thermal control” prevents throttling. According to PcComponentes buyers, temperatures stay between 30–50°C with adequate motherboard heatsinks. However, multiple reports point to heat accumulation under continuous transfers — one PCPartPicker builder labeled it “a pain to keep cool” without proper case airflow.

Cross-Platform Consensus
Universally Praised
Across Amazon, PCPartPicker, and PcComponentes, speed is the consistent headline. Gamers on Reddit highlight near-zero load times for large open-world textures, while software engineers compiling heavy codebases notice compile-time drops of minutes. A PCPartPicker story recounts moving from a Corsair drive with “lag in high file volumes” to a 990 PRO with “0 stutters.”
Creative professionals cite the high IOPS figures as transformative for raw photo and 4K/8K video workflows. One Quora participant running multiple Adobe suite processes in parallel praised the way the drive “keeps all scratch disks responsive” without dipping.
Laptop users appreciate lower idle power draw — often under 50 mW — which extends battery life while traveling. This is paired with support for device sleep modes, which keeps the SSD effectively invisible to battery drain during standby.
Common Complaints
Firmware history weighs heavily in certain buying decisions. PcComponentes reviewers repeatedly mention earlier units suffering accelerated wear rates observable via SMART health checks. Samsung’s 1B2QJXD7 firmware release is credited with halting degradation, but community notes stress it “does not repair existing damage.” Trustpilot entries underline frustration when repairs required multiple weeks.
Price sensitivity is notable: while eBay listings occasionally dip under $130 for 1TB variants, Amazon and PCPartPicker users debate whether the performance uplift over cheaper competitors — including Samsung’s own 980 PRO — merits the outlay.
Thermals surface often. Without a heatsink, sustained multi-hour transfers (e.g., moving terabytes of raw video) can push temperatures toward throttling thresholds. PS5 owners using the non-heatsink model have echoed this, prompting recommendations to opt for the dedicated heatsink SKU.
Divisive Features
The heatsink itself creates split opinions. Console users welcome the stability and minimal fan noise the slim design offers, while desktop PC modders sometimes view it as redundant when their cases already house premium cooling solutions. Similarly, Samsung Magician software draws praise for its cloning and benchmarking tools, but a few advanced users critique its “Samsung ecosystem lock-in,” preferring platform-agnostic solutions.

Trust & Reliability
Samsung’s long-standing reputation as the “world’s #1 flash memory brand” carries weight, but the 990 PRO’s early-life wear controversy temporarily clouded that image. Trustpilot’s low outlier rating reflects isolated incidents of defective units being returned. However, Reddit and PcComponentes posts now generally show sustained top performance months after installation, with health percentages stable post-firmware update.
Long-term reliability stories from PCPartPicker thread archives (spanning 6–12 months of use) reveal consistent speed delivery and minimal capacity loss — particularly for users in creative fields performing daily large writes. While TBW specs are lower than some rivals, the drive still meets the operational needs of power users who cycle through projects, not archival storage.
Alternatives
The most frequent comparison in user discussions is Samsung’s 980 PRO, which delivers roughly 90% of the 990 PRO’s performance at a steeper discount. For buyers whose workflows don’t max random IOPS, the 980 PRO is seen as a “better value pick,” especially after firmware updates improved its thermal handling.
Western Digital’s SN850X surfaces in Twitter threads as an alternative for gamers, with slightly higher endurance ratings but a noisier heatsink design. For strictly price-driven purchases, eBay listings of Gen4 competitors often undercut the 990 PRO significantly, though community consensus warns of potential firmware quirks and lower sustained speeds.
Price & Value
Market tracking on eBay shows 1TB models regularly available between $100–$130, sometimes undercutting Amazon listings. The 2TB variant ranges from $150–$190 on discount, while the 4TB model commands $280–$480 depending on availability spikes. Resale demand appears strong, with used units selling close to retail for capacities 2TB and above.
Community buying tips emphasize timing purchases during “World Storage Day” or major tech sale events, where the 990 PRO can dip close to 980 PRO pricing. For PS5 owners, factoring in the heatsink cost upfront avoids aftermarket purchases.

FAQ
Q: Is the Samsung 990 PRO compatible with PS5?
Yes, both heatsink and non-heatsink versions fit within PS5’s M.2 slot specifications. Users recommend the heatsink variant for optimal thermal performance.
Q: Has the early wear issue been fixed?
Samsung’s firmware update (1B2QJXD7) addresses premature wear for new units. Existing degraded drives cannot be restored but will stabilize post-update.
Q: Does the 990 PRO support hardware encryption?
Yes, it offers AES 256-bit encryption, TCG/Opal, and IEEE 1667 support for secure storage applications.
Q: How hot does it run under load?
Without a heatsink, sustained heavy writes can increase temperatures toward throttling levels, especially in compact cases. Adequate cooling is advised.
Q: What’s the warranty coverage?
5 years or up to 600 TBW for 1TB, 1200 TBW for 2TB, and 2400 TBW for 4TB variants, whichever comes first.
Final Verdict
Buy if you’re a high-performance gamer, creative professional handling large video/photo datasets, or a laptop user needing speed with lower power draw — especially if you secure it at a sale price. Avoid if budget-sensitive and the uplift over the 980 PRO won’t be fully utilized in your workflow. As many users advise: always check firmware version before use, and for heavy sustained loads, invest in proper cooling.
