About Samsung 990 Evo 1TB PCIe 5.0 NVMe SSD
The Samsung 990 EVO 1TB is a versatile NVMe SSD designed to offer a balance of performance, power efficiency, and broad compatibility. While marketed as a Gen 5 drive, it's a unique product that operates on a PCIe 5.0 x2 interface, which is half the bandwidth of a typical Gen 5 SSD. This makes it backward compatible with PCIe 4.0 x4 slots, where it can still achieve its full rated speeds.
The drive delivers sequential read speeds of up to 5,000 MB/s and sequential write speeds of up to 4,200 MB/s. These speeds, while not at the top-tier of Gen 5 drives, are still a significant upgrade over older SSDs and are more than sufficient for most everyday tasks, gaming, and content creation. Its design focuses on power efficiency, boasting a 70% improvement over its predecessor, which is especially beneficial for laptops and portable systems.
Despite being a DRAM-less SSD, the 990 EVO utilizes Host Memory Buffer (HMB) to maintain performance without the need for a dedicated DRAM chip, which helps to keep its cost down. It is a single-sided M.2 2280 form factor, making it compatible with a wide array of devices. With a Total Bytes Written (TBW) rating of 600 TB and a 5-year limited warranty, the drive offers solid durability and reliability.
