Actual performance varies depending on system configuration, workload, available TurboWrite cache, drive capacity usage, and other operating conditions.

Samsung V-NAND Technology

The 870 QVO uses Samsung V-NAND flash technology to provide high-capacity solid-state storage in a compact 2.5-inch drive.

Benefits include:

• Fast electronic data access
• High storage density
• No mechanical moving components

• Reliable everyday storage
• Efficient compact construction

The QVO series uses QLC NAND technology, allowing Samsung to provide larger SSD capacities at a more accessible cost per gigabyte than many performance-oriented TLC-based SSDs.

Intelligent TurboWrite

Samsung's Intelligent TurboWrite technology helps accelerate write performance by using a high-speed write buffer.

This can improve performance during:

• File transfers
• Application installation
• Game installation
• Software updates
• Everyday write workloads
• Multimedia transfers

Performance can decrease during sustained large writes after the available TurboWrite cache has been exhausted.

SATA III 6Gb/s Interface

The Samsung 870 QVO connects through a standard SATA III 6Gb/s interface.

Benefits include:

• Broad desktop compatibility
• Compatibility with many laptops
• Straightforward HDD replacement
• Mature SATA technology
• Easy storage upgrades
• Strong everyday SSD performance

The drive can also operate with compatible earlier SATA interfaces, although maximum performance will be limited by the host interface.

2.5-Inch Form Factor

The 2.5-inch form factor makes the Samsung 870 QVO suitable for a wide variety of compatible systems.

Potential applications include:

• Desktop PCs
• Gaming PCs
• Compatible laptops
• Workstations
• Office computers
• Home PCs
• Older systems being upgraded from HDD storage

Users should verify that their system provides the appropriate physical mounting space and SATA connection.
