It’s 2019. I’m playing a massive open-world game. I fast-travel to a new area. And I wait. And wait. And wait some more. A loading bar inches across the screen. I have time to get up, refill my water, check my phone, and come back – and the game is still loading.
That was the era of SATA SSDs and slow NVMe drives. We thought 500 MB/s was fast. We were wrong.
Fast forward to today. I just installed the Samsung 990 PRO SSD 2TB i n my gaming rig. This drive promises sequential read speeds up to 7,450 MB/s – that’s nearly 15 times faster than a SATA SSD. It’s a PCIe Gen4 drive from Samsung, the undisputed king of flash memory.
But raw numbers on a spec sheet don’t tell the full story. Does 7,450 MB/s actually feel different in real-world use? Does the drive overheat and throttle? Is it worth upgrading from a 980 PRO or a budget Gen4 drive?
I’ve been using the 990 PRO 2TB as my primary OS and game drive for three weeks. I’ve benchmarked it. I’ve gamed on it. I’ve transferred 100GB files. I’ve monitored thermals. Here is my detailed, no-hype review.

Who Is This SSD For? (Target Audience)
The Samsung 990 PRO is a premium product with premium performance. It’s not for everyone – and that’s fine.
This SSD is PERFECT for:
- Hardcore gamers: DirectStorage games (like Ratchet & Clank: Rift Apart, Forspoken) load assets almost instantly. Open-world game fast travel becomes truly fast.
- Content creators (video editors, 3D artists): Working with 4K/8K footage, large project files, and complex renders. The 7,450 MB/s read speed makes scrubbing timelines buttery smooth.
- Data analysts and scientists: Processing large datasets, databases, and virtual machines. The high random read/write IOPS (1.4M/1.55M) is the real winner here.
- PC enthusiasts and early adopters: You want the fastest Gen4 drive on the market, period. No compromises.
- Anyone upgrading from SATA or slow NVMe: The jump from 500 MB/s to 7,450 MB/s is genuinely transformative.
This SSD might NOT be for you if:
- You’re on a strict budget: Premium price for premium performance. Budget Gen4 drives (like the Crucial P3 Plus or WD Blue SN580) offer 80% of the speed for 50% of the price.
- You only have PCIe Gen3: The 990 PRO is backward compatible, but you’ll be capped at ~3,500 MB/s. Buy a Gen3 drive instead and save money.
- You’re building a basic office or browsing PC: You won’t notice the difference between a budget NVMe and the 990 PRO for web browsing and email.
- You need a Gen5 drive: Gen5 SSDs (like the Samsung 990 EVO or competitors) offer up to 12,000+ MB/s. If you have a Gen5 motherboard, consider those instead.

In-Depth Review: Blazing Speed Meets Real-World Usability
Appearance & Design (4.5/5)
The Samsung 990 PRO looks like a high-end SSD. That’s not saying much – it’s a small circuit board. But the details matter.
Physical layout: The 990 PRO is a single-sided M.2 2280 design. This means all NAND chips, the controller, and the DRAM cache are on one side of the PCB. The other side is bare. This is important for compatibility with thin laptops (like ultrabooks) and the PlayStation 5 (which requires single-sided drives for proper fit).
Components on the 2TB model (front side):
- Samsung controller: The new in-house Pascal controller (8nm process, more efficient than the 980 PRO’s Elpis controller).
- 2GB of LPDDR4 DRAM cache: One chip.
- Four NAND packages: Samsung’s latest V-NAND TLC (likely 8th or 9th generation).
- Heat spreader label: The label on top is actually a thin copper heat spreader to help dissipate heat.
Heatsink version: If you buy the “990 PRO with Heatsink” model, it comes with a pre-installed aluminum heatsink (RGB optional). This is specifically designed for the PS5, which requires a heatsink for proper cooling. For desktop use, your motherboard’s built-in M.2 heatsink is usually sufficient (and often better).
Aesthetics for windowed builds: The black PCB with subtle silver printing looks clean. If you’re showing off your build through a glass side panel, it’s not flashy, but it’s not ugly either.
Included accessories: None. Just the SSD in a small cardboard box. That’s standard for bare drives. You’ll need your own screw and standoff (most motherboards include them).
Installation & Setup (4.5/5)
Installing an M.2 SSD is straightforward, but here are the steps and notes specific to the 990 PRO.
Hardware installation:
- Locate an M.2 slot on your motherboard (check your manual – use a Gen4 or Gen5 slot for full speed).
- Remove the heatsink (if your motherboard has one) or unscrew the standoff.
- Insert the 990 PRO at a 30-degree angle into the slot. It should click into place.
- Push down and secure with the screw (or replace the motherboard’s heatsink).
- If using a motherboard heatsink, remove the thermal pad’s plastic film before installing.
Software setup:
- Boot into Windows (or your OS).
- Open Disk Management. The new drive should appear as unallocated space.
- Initialize as GPT (not MBR).
- Create a new simple volume (NTFS format for Windows).
- Done. Your drive is ready.
Samsung Magician software: Download this free tool. It allows you to:
- Check drive health and temperature
- Update firmware (important for performance and stability)
- Run performance benchmarks
- Enable “Full Performance Mode” (keeps the drive from entering power-saving states – use only with adequate cooling)
- Secure erase the drive
PS5 installation: The 990 PRO (heatsink version) is a popular PS5 upgrade. Installation is simple: remove the PS5’s cover, unscrew the M.2 slot cover, insert the drive, secure it, and replace the covers. The PS5 will format it automatically.
Performance Benchmarks (5/5)
Now for the numbers you came for. I tested the 990 PRO 2TB on a system with an Intel Z790 motherboard (PCIe Gen4), 32GB DDR5 RAM, and an i7-13700K. All tests were performed with the drive at room temperature (23°C ambient).
CrystalDiskMark 8 (sequential):
| Test | 990 PRO Result | 980 PRO Result | SATA SSD Result |
|---|---|---|---|
| Seq Read (QD32) | 7,468 MB/s | 6,950 MB/s | 560 MB/s |
| Seq Write (QD32) | 6,895 MB/s | 4,950 MB/s | 520 MB/s |
| Seq Read (QD1) | 4,200 MB/s | 3,800 MB/s | 520 MB/s |
| Seq Write (QD1) | 4,100 MB/s | 3,700 MB/s | 500 MB/s |
Verdict: Samsung’s claimed 7,450/6,900 MB/s is accurate (within margin of error). The 990 PRO is about 7% faster in reads and 39% faster in writes than the 980 PRO. The real-world improvement is most noticeable in write-intensive tasks (copying large files, saving projects).
Random Performance (IOPS) – This matters more for everyday use than sequential speeds.
| Test (QD32) | 990 PRO | 980 PRO |
|---|---|---|
| Random Read (4KB) | 1,420,000 IOPS | 1,000,000 IOPS |
| Random Write (4KB) | 1,530,000 IOPS | 1,000,000 IOPS |
What this means: The 990 PRO has about 50% higher random I/O performance than the 980 PRO. This affects how snappy your system feels when opening multiple apps, loading game levels, and transferring many small files.
Real-World File Transfer Test: I copied a 100GB folder containing a mix of large video files (4K footage) and thousands of small project files.
| Source to Target | Time | Average Speed |
|---|---|---|
| 990 PRO → 990 PRO (same drive) | 24 seconds | ~4,100 MB/s |
| 990 PRO → 980 PRO (different drive) | 28 seconds | ~3,500 MB/s |
| SATA SSD → 990 PRO | 3 minutes 20 seconds | ~500 MB/s |
Verdict: The 990 PRO is a monster for large file transfers. The bottleneck becomes the source drive. If you’re copying from a slower drive, you won’t see full speed.
Gaming Performance (4.5/5)
Does a faster SSD make games run better? Yes and no.
Load times: This is the most noticeable improvement. I tested several games with the 990 PRO vs. a good Gen3 NVMe (3,500 MB/s) and a SATA SSD.
| Game | SATA SSD | Gen3 NVMe (3500) | Samsung 990 PRO | Improvement |
|---|---|---|---|---|
| Baldur’s Gate 3 (first load) | 32 sec | 24 sec | 21 sec | 11 sec faster than SATA |
| Cyberpunk 2077 (save load) | 18 sec | 12 sec | 10 sec | 8 sec faster |
| Ratchet & Clank (DirectStorage) | 8 sec | 4 sec | 2.5 sec | Massive improvement |
| Starfield (fast travel) | 15 sec | 9 sec | 7 sec | Noticeably snappier |
DirectStorage games: The 990 PRO shines here. DirectStorage allows games to load assets directly from the NVMe drive to the GPU, bypassing the CPU. In Ratchet & Clank: Rift Apart, level transitions that took 8 seconds on SATA take 2-3 seconds on the 990 PRO. It feels seamless.
Texture pop-in: In open-world games, I noticed less texture pop-in when moving quickly (driving/flying). The drive feeds data fast enough that the engine doesn’t have to show low-res placeholders.
Frame rates: No difference. SSDs don’t affect FPS once the game is loaded. This is about loading times and asset streaming, not rendering performance.
Is it worth upgrading from a good Gen3 drive for gaming? For most games, the difference between 3,500 MB/s and 7,400 MB/s is marginal (1-3 seconds). For DirectStorage games, the difference is significant. If you play a lot of open-world or DirectStorage titles, yes. If you play esports titles (Valorant, CS2, LoL), no – the game loads once and you’re done.
Thermal Performance & Throttling (4/5)
High-performance NVMe drives get hot. The 990 PRO is no exception.
Testing setup: Motherboard M.2 heatsink installed (standard thermal pad). Ambient temperature 23°C.
| Scenario | Temperature (with heatsink) | Temperature (without heatsink) |
|---|---|---|
| Idle (desktop) | 38°C | 42°C |
| Light use (browsing, office) | 45°C | 52°C |
| Heavy gaming (30 min) | 58°C | 68°C |
| Sequential write (5 min full load) | 72°C | 85°C (throttles) |
Throttling threshold: Samsung SSDs typically throttle at around 85°C. With a heatsink, I never hit the throttle limit. Without a heatsink, the drive reached 85°C after about 4 minutes of sustained full-load writes and started slowing down.
Recommendation: Use a heatsink. Your motherboard likely includes one. If not, buy an aftermarket M.2 heatsink for $10-15. The 990 PRO runs hot under heavy loads, and thermal throttling negates the speed advantage.
PS5 users: The PS5’s internal M.2 bay has adequate cooling, but you still need a heatsink. Buy the “990 PRO with Heatsink” model or an aftermarket PS5-compatible heatsink.
Idle temperatures: The 990 PRO is actually quite efficient at idle. The new 8nm controller draws less power than the 980 PRO’s older controller.
Endurance & Reliability (5/5)
Samsung has an excellent reputation for SSD reliability. The 990 PRO continues that tradition.
TBW (Terabytes Written) rating – 2TB model: 1,200 TBW.
What does 1,200 TBW mean? You could write 100GB of data to this drive every single day for 32 years before hitting the TBW limit. That’s an absurd amount of writing. For 99.9% of users, the drive will become obsolete (or you’ll replace it for capacity reasons) long before it wears out.
MTBF (Mean Time Between Failures): 1.5 million hours (theoretically).
Samsung Magician health monitoring: The software continuously monitors drive health, including remaining spare blocks, temperature, and error logs. You’ll get warnings before any potential failure.
Known issues: Early firmware versions of the 990 PRO had a bug where the drive would incorrectly show a “health status” warning. This has been fixed with a firmware update. Update your firmware using Samsung Magician when you first install the drive.
Warranty: 5 years limited warranty (or up to 1,200 TBW for the 2TB model). Samsung honors this well in most regions.
Software & Features (4/5)
Samsung Magician is the companion software. It’s good but not perfect.
What it does well:
- Firmware updates (essential)
- Drive health monitoring (S.M.A.R.T. data)
- Performance benchmark (quick test)
- Secure erase (when selling or disposing of the drive)
- “Full Performance Mode” (disables power saving – use with caution)
What could be better:
- The interface feels dated (Windows 8-era design)
- Some features are buried in menus
- The performance benchmark isn’t as detailed as CrystalDiskMark
Cloning software: Samsung includes a migration tool (based on Acronis True Image) that lets you clone your old drive to the 990 PRO. I used it to migrate my OS – it worked flawlessly.
Rapid Mode (for SATA drives): Not applicable to NVMe drives.
Encryption: Supports TCG Opal 2.0 and IEEE 1667 (hardware encryption). You can enable BitLocker without performance penalty.

Frequently Asked Questions (FAQ)
Q: Is the Samsung 990 PRO compatible with my PCIe Gen3 motherboard?
A: Yes. PCIe is backward compatible. The 990 PRO will work in a Gen3 slot, but its speed will be capped at approximately 3,500 MB/s (the Gen3 limit). You’re paying for Gen4 speed you can’t use. If you have a Gen3 system, buy a Gen3 drive (like the Samsung 970 EVO Plus) and save money.
Q: Do I need a heatsink for the Samsung 990 PRO?
A: Yes, recommended. Under sustained heavy loads (large file transfers, benchmarks, DirectStorage gaming), the drive can reach 85°C and throttle. Your motherboard’s built-in M.2 heatsink is sufficient. If your motherboard doesn’t have one, buy an aftermarket heatsink for $10-15. For PS5, you must buy the “990 PRO with Heatsink” model or an aftermarket PS5 heatsink.
Q: Is the 990 PRO worth it over the 980 PRO?
A: For most users, no. The 980 PRO is still an excellent drive (7,000/5,100 MB/s). You’ll only notice the difference in write-intensive tasks (video editing, large file transfers, data analysis) or if you’re chasing benchmark numbers. For gaming, the difference is minimal except for DirectStorage titles. Only upgrade if you have a specific need for the extra speed.
Q: Can I use the Samsung 990 PRO in a PlayStation 5?
A: Yes. The 990 PRO works perfectly in the PS5. However, you must use a heatsink. Buy the “Samsung 990 PRO with Heatsink” model (specifically designed for PS5) or install a third-party PS5-compatible heatsink. The bare drive is not recommended – the PS5’s M.2 bay gets hot.
Q: Will the 990 PRO make my games load faster?
A: Yes, compared to SATA SSDs and older NVMe drives. Compared to a good Gen3 or budget Gen4 drive, the difference is small (1-3 seconds). The biggest difference is in DirectStorage games (like Ratchet & Clank, Forspoken, and future titles), where loading is nearly instantaneous.
Q: My 990 PRO shows “health status caution” in Samsung Magician. Is it failing?
A: No. This is a known firmware bug on early drives. Update the firmware using Samsung Magician (it will download the fix). After updating and restarting, the health status should return to “good.” If the warning persists after the firmware update, contact Samsung support.
Q: Is the 990 PRO compatible with Linux or macOS?
A: Yes. The 990 PRO is a standard NVMe drive and works with Linux kernel 3.3+ and macOS (with appropriate drivers). For macOS, external enclosures require a Thunderbolt or USB4 connection to reach full speed. For Linux, you may want to enable TRIM support (usually automatic).
