Samsung - 990 PRO 1TB Internal SSD PCle Gen 4x4 NVMe

I installed the Samsung 990 PRO NVMe in my Framework Laptop 13, and the biggest thing to understand is this: this drive is built to push the limits of PCIe 4.0, and the Framework actually lets it stretch its legs. The 990 PRO is a PCIe Gen 4 ×4 NVMe drive. That means it communicates directly over four PCIe lanes instead of using the older SATA interface. In practice, that translates to theoretical read speeds up to about 7,450 MB/s and write speeds around 6,900 MB/s. SATA tops out near 550 MB/s. This isn’t a small bump - it’s an order-of-magnitude jump. In the Framework 13, those speeds are real. The laptop supports full Gen 4 bandwidth, so you’re not leaving performance on the table. Large file transfers move absurdly fast. Cloning drives or copying multi-gigabyte datasets feels closer to RAM behavior than old-school storage. Where NVMe really shows its strength isn’t just sequential speed. It’s queue depth and latency. The 990 PRO handles a huge number of small read/write requests simultaneously. That’s what makes the system feel sharp when you’re multitasking. Browser tabs loading, background indexing, compiling code, and OS processes can all hit the drive at once without it stalling. The controller and NAND design matter here. Samsung uses its own in-house controller and V-NAND. The firmware is mature, and the drive manages its SLC cache intelligently. During sustained writes, once the cache fills, speeds drop - that’s normal for TLC-based drives - but the recovery is fast and consistent. In everyday use, you rarely hit that wall unless you’re pushing hundreds of gigabytes at once. Thermals are surprisingly controlled for a high-performance NVMe. NVMe drives can run hot because they’re effectively tiny PCIe computers. In the Framework 13, the 990 PRO gets warm under stress, but it doesn’t aggressively throttle during typical workloads. For daily use, it’s stable. Power efficiency is another quiet strength. High-end NVMe drives used to be battery killers. The 990 PRO is much better at entering low-power states when idle. In a laptop context, that matters more than peak benchmark numbers.

Samsung makes the best SSDs hands down. I have used them in over 30 computers in the last 15 years with no issues at all. One even has 24TB written to it. Sure, other competitors are catching up, but they just cannot top the performance, reliability, and longevity. I have tested the 990 Pro up against the 970 Evo, 980 Pro (Gen 4), Western Digital SN810 (Gen 4), and Crucial (Gen 4). Just make sure your 990 Pro firmware is up to date! The prior issues with some of the 980 Pros and 990 Pros was solved with the firmware update. I have recently installed 990 Pros in 4 HP Omen laptops and tested the above mentioned competitors in the same laptops. The others can come close to beating the 990 Pro on a segment or 2 on CrystalDisk, but there is a significant difference in the 990 Pro. The Western Digital did surprisingly well. I have included a pic of a WD test and a 990 Pro test. Neither were enhanced, optimized, or set to performance. Just a straight out of the box test on laptops with less than 30 minutes of up time. Side Note: The UserBenchmark test had a hard time reading the 990 Pro for some reason, but was able to test the others just fine.

This nvme has amazingly fast speeds. It is a perfect representation of new gen tech. This ssd works works perfectly with my matching 990 pro nvme. 10/10 amazing purchase would recommend.

Great SSD m.2 for the money very very fast even when using a pc that only have PCI-E gen 3 loads up games very quickly start up time is way faster than my old ssd definitely a noticeable difference when playing games and their load times haven’t had issues also if you do buy make sure you download Samsung magician and UPDATE IMMEDIATELY to make sure that the old firmware doesnt shorten the life of it since it’s a know problem with these m.2 980 and 990 evo

it’s a fast and reliable gen 4 nvme ssd. not the fastest but definitely a great value for the money. box came damaged during shipping but no harm was done to the product
