Capacity for the Installed Library

The 2 TB capacity provides internal space for the system and its files. Plan room for the operating system, applications, game updates and working files when choosing the drive. Some of the labelled capacity is used for formatting and drive functions, so usable space depends on the operating environment. Keep a separate backup arrangement for files that need to be retained.

Sequential Transfer Performance

Sequential read: 7450 MB/s. Sequential write: 6900 MB/s. These are manufacturer maximum figures under the specified test conditions. Actual transfers depend on the host hardware, software, available cache, temperature and workload. Use the capacity-specific figures when comparing this drive with another option, particularly where a larger version of the same family has a different write rating.

Match the Storage Interface

The drive uses PCIe 4.0 x4, NVMe 2.0 in a M.2 2280 NVMe format. Check that the intended M.2 slot accepts a 2280-length PCIe NVMe drive and supports the required interface. The host connection determines the available link speed, so confirm the system specification before planning an upgrade.

The Samsung 990 PRO Hardware

The 2 TB 990 PRO combines Samsung V-NAND TLC with an in-house controller and 2 GB LPDDR4 cache. The NVMe 2.0 platform includes drive-management features such as TRIM, S.M.A.R.T. and garbage collection. These characteristics describe the selected drive family and capacity. Use them alongside the interface and performance figures when choosing storage for a desktop or compatible notebook. Keep any service or firmware work within the manufacturer’s supported procedure and maintain a backup of important files before changing a storage installation.

Capacity-Specific Write Endurance

The rated write endurance is 1200 TBW. TBW means terabytes written and describes a tested write-workload rating. It is not the same as usable capacity or a guaranteed number of years of operation. Consider the expected write workload when choosing a drive for application files, game installations, recordings or project data.
