990 EVO performance for compatible client systems
The Samsung 990 EVO 1TB MZ-V9E1T0BW combines Samsung V-NAND, an in-house controller and the PCIe 4.0 x4 / PCIe 5.0 x2 interface in a compact M.2 2280 format. Its capacity-specific performance, cache design, endurance and thermal configuration are stated separately so buyers can match the exact SKU to a supported system.
Up to 5,000MB/s read
Samsung rates this exact 1TB model up to 5,000MB/s sequential read under its published test conditions.
Up to 4,200MB/s write
The capacity-specific sequential write rating is up to 4,200MB/s with the supported write-acceleration feature active.
680K IOPS/800K IOPS random IOPS
QD32 random performance is rated up to 680K IOPS read and 800K IOPS write for this exact capacity.
HMB cache design
Host Memory Buffer uses host-system memory rather than dedicated onboard DRAM, as specified for the 990 EVO.
600TBW endurance
Samsung specifies 600TBW for this capacity, with warranty coverage governed by the stated period or endurance limit.
Thermal management
Proper airflow and a suitable host thermal arrangement help the drive operate within its specified temperature range.
Who is the Samsung 990 EVO 1TB MZ-V9E1T0BW best for?
A strong choice for
- Compatible desktop and workstation storage upgrades
- Supported client-PC boot and application drives
- Gaming, creative and productivity workloads within the published profile
- Users needing 1TB nominal capacity
- Buyers who want Samsung Magician management support
Consider another model if you need
- Your system lacks a compatible M.2 2280 NVMe slot
- You require performance beyond 5,000MB/s/4,200MB/s
- You need a data-centre or enterprise endurance profile
- Your system requires a factory-fitted heatsink
