The Samsung 990 PRO 1TB is a high-performance PCIe 4.0 NVMe SSD delivering up to 7,450 MB/s read and 6,900 MB/s write speeds with strong security features. Its heatsink-less design and limited pSLC cache can limit sustained heavy workloads. Best suited for gamers, content creators, and professionals who need maximum PCIe 4 throughput on desktops or laptops with adequate cooling.

The WD_BLACK SN770 2TB is a DRAM-less PCIe Gen4 SSD delivering up to 5150 MB/s reads and 4850 MB/s writes with a robust 1200 TBW endurance. Its budget-friendly price and low power draw come at the cost of no onboard DRAM and no included heatsink, which can limit sustained performance under heavy loads. Ideal for gamers and mainstream builders seeking fast sequential performance without the premium price.

The Crucial P310 2TB M.2 SSD offers flagship-class PCIe Gen4 speeds of up to 7,100 MB/s read and 6,000 MB/s write in a budget-friendly, single-sided package. Its QLC NAND limits endurance and performance falls after the cache is exhausted. Suited for gamers and laptop upgraders seeking high speed at low cost.

The Corsair MP600 Elite 2TB is a budget-oriented PCIe 4.0 NVMe SSD delivering up to 7,000 MB/s read and 6,500 MB/s write speeds with AES-256 encryption and a low-profile heatsink. Its DRAM-less design and limited cache reduce sustained write performance compared to higher-end models. Ideal for gamers and laptop users who want solid PCIe 4.0 performance without a premium price tag.

The WD Blue SN5000 2TB is a DRAM-less PCIe Gen4 SSD with up to 5150 MB/s reads, a large >300 GB pSLC cache, and 900 TBW endurance for creative workloads. While it offers strong performance, the lack of DRAM can affect random I/O and real-world speeds may fall short of advertised peaks. Suited for creators and professionals needing high sequential throughput on a PCIe Gen4 platform.

The Silicon Power UD90 1TB is a PCIe 4.0 NVMe SSD achieving up to 5,000 MB/s read and 4,800 MB/s write with a large 69 GB SLC cache. Write performance throttles once the cache is exhausted and the drive lacks DRAM and hardware encryption. Targeted at gamers and creators seeking high speed on a budget.

The Kingston NV3 1TB is a budget-oriented PCIe 4.0 NVMe SSD delivering up to 6,000 MB/s read and 4,000 MB/s write in a tiny single-sided M.2 2280 package. Its DRAM-less design leads to inconsistent random performance and occasional throttling under heavy loads. It is ideal for gamers and creators who need high sequential speeds without the premium price.
