This article explains the cause of this issue and provides the fix for write amplification observed on Intel® SSD(Solid State Drive) 535, 530, Pro 2500 and 540s Series
Why does my SSD have high total NAND(Not AND) writes as opposed to total Host writes.
Write amplification (WA) is an undesirable phenomenon associated with flash memory and solid-state drives (SSDs) where the actual amount of information physically written to the storage media is a multiple of the logical amount intended to be written. This has been observed on the Intel SSDs.
Here's how to fix write amplification on Intel 535, Intel 530 and Pro 2500 SSDs
- Install the WAF(Write amplification Factor) fix firmware. You can find the update here
- If the issue persists, perform a secure erase on the drive. Check this link for tools on performing a secure erase/low-level format
- If the issue persists, contact Intel Customer Support for assistance
For Intel 540s SSD, contact Intel Customer Support for assistance.
