FLASH WEARING

Wear leveling is a technique for prolonging the service life of some kinds of erasable computer storage media, such as flash memory, which is used in solid- state. Another limitation is that flash memory has a finite number of , P/E cycles before the wear begins to deteriorate the.

SSD WEAR

This article provides information on why SSD's wear out. NAND flash devices can be either single-level cell (SLC) or multi-level cell (MLC). Wear-leveling results in a nearly even distribution of write accesses across the total capacity of the SSD. This means, by only reading data, an SSD will not wear out, which brings us to the conclusion that it depends on the write and delete processes.

FLASH WRITE BALANCING

Wear Unleveling: Improving NAND Flash Lifetime by Balancing Page Endurance while minimally affecting (sometimes improving) the write performance. Wear leveling is a technique for prolonging the service life of some kinds of erasable computer EEPROM and flash memory media have individually erasable segments, In this way, no single erase block prematurely fails due to a high concentration of write .

SOLID STATE MEMORY SYSTEMS

Solid-state storage (sometimes abbreviated as SSS) is a type of non-volatile computer storage To satisfy the requirements of applications in various types of computer systems and appliances, solid-state storage devices come in various. SSDs were originally designed for use in a computer system. as an SSD, but they are not intended to be the primary storage.

LINUX WEAR LEVELING

To answer the core question, yes, but your drive is suffering from suboptimal performance. (I've reposted the SMART data to GitHub Gist.). It seems linux is not aware it is running on a flash medium and does not trim freed blocks, which basically kills wear leveling after a while.
