Design & Build Quality
The Samsung 990 EVO Plus sticks to a minimalist design typical of modern M.2 NVMe SSDs. It’s compact, slim, and bare—no integrated heatsink, no unnecessary RGB, just a pure focus on efficiency and thermal management.
Despite its modest exterior, it uses Samsung’s latest 7th-gen V-NAND and an in-house controller codenamed “Pablo,” designed for power efficiency without sacrificing performance. The lack of DRAM is mitigated with Host Memory Buffer (HMB), which allows the SSD to use a portion of the system’s RAM as a cache. While not as fast as onboard DRAM, HMB does provide reliable caching for daily workloads.
Interface & Compatibility
The biggest talking point of the 990 EVO Plus is its dual-interface support:
-
PCIe 4.0 x4 (standard on desktops and newer laptops)
-
PCIe 5.0 x2 (forward-compatible with Gen 5 slots)
This hybrid compatibility means you can use this SSD in a wide range of devices, from older PCIe 3.0 laptops to cutting-edge Gen 5 motherboards. Though it's not a true PCIe 5.0 x4 drive like the Samsung 990 Pro, it can still take advantage of Gen 5 bandwidth via two lanes for better efficiency and futureproofing.
NVMe 2.0 support further enhances compatibility, power management, and queuing behavior.

1. CrystalDiskMark (Sequential Performance)
1TB Samsung 990 EVO Plus
-
Read: 5,019 MB/s
-
Write: 4,212 MB/s
This is about 30–40% faster than the 970 EVO Plus, and just slightly behind premium PCIe 4.0 drives like WD Black SN850X or Samsung 980 Pro.
2. 4K Random Read/Write
-
4K Read (QD1): 83 MB/s
-
4K Write (QD1): 224 MB/s
-
4K Read (QD32): 950 MB/s
-
4K Write (QD32): 915 MB/s
For consumer workloads like booting, launching apps, and browsing, 4K random performance is crucial. The 990 EVO Plus offers significantly improved 4K speeds compared to older Gen 3/4 SSDs in the same price range.
3. PCMark 10 Full Storage Benchmark
-
Score: 4,780
-
Bandwidth: 640 MB/s
