Samsung 990 EVO 2TB
Score: 87/100
Sabrent Rocket 4 2TB
Score: 74/100Rankings
The Samsung 990 EVO 2TB offers a balanced mix of high random performance, strong power efficiency and modern PCIe flexibility, making it ideal for laptops and compact PCs. Its DRAM-less design keeps costs and power low, though heavy write workloads may see a slowdown once the cache is depleted.
The Sabrent Rocket 4 2TB is a high-performance PCIe 4.0 internal SSD offering excellent read/write speeds and IOPS, with a lightweight M.2 2280 form factor, but it lacks a bundled heatsink and has moderate endurance.

Professional reviewers praise the 990 EVO for its flexible dual-mode PCIe support, strong power efficiency and solid random performance, while noting that raw sequential speeds lag behind flagship models and sustained writes are not class-leading.
Everyday users rate the drive highly, highlighting easy installation, fast boot times and noticeable gains over older SATA or PCIe 3.0 SSDs, with occasional complaints about the lack of a heatsink and DRAM-less architecture.
“Excellent random 4K performance for a DRAM-less SSD, outperforming older models like the 980 PRO in some benchmarks.”
“Users consistently rate the drive highly (4.8-5.0 stars across platforms), praising its ease of installation and fast boot times.”
“The single-sided design fits perfectly in my mini-PC and stays cool.”
Professional reviewers note that the Rocket's TLC NAND and DRAM give it reliable, sustained performance, and the implied Phison E16 controller is a solid choice for PCIe 4.0 workloads. While it doesn't match the raw speed of flagship drives like the Samsung 980 Pro, its price-to-performance ratio makes it a compelling option for gamers and creators.
Everyday users consistently praise the Rocket for its speed, affordability, and ease of installation, often highlighting fast boot times, quick game loads, and the usefulness of the bundled cloning software. Common complaints revolve around the missing mounting screw, lack of an included heatsink, and a few isolated early-failure reports.
