Notes:

• The working components of SSDs do not degrade when performing read-only tasks.
• TLC NAND – generally speaking, the fewer data bits assigned to a memory cell, the longer a drive will last
• TurboWrite – Both the QVO and EVO drives make use of Samsung’s Intelligent TurboWrite system. TurboWrite allows lower quality drives (in this case, the QLC format of the QVO drives) to simulate the write speeds of drives that are technically superior—like the TLC format of EVO drives.
• * Performance – the TLC of EVO drives will perform substantially better after TurboWrite runs out of operating memory, e.g when writing very large files
• The Samsung SSD PRO line of products makes use of MLC (2 data bits/cell)
