Why Samsung 970 EVO Plus Slow Write Speed Happens 

Slow write speed is a very annoying problem; by analyzing several cases in the forum, we summarized the following possible reasons for the slow write speed of the Samsung 970 EVO Plus:

  • High temperature: If the Samsung 970 exceeds the SSD temperature range, it may affect its write and read speed.
  • Slot: To get the full speed of a PCIE 3.0 x4 NVME drive, the M.2 PCIE adapter must be installed in a slot that supports PCIE 3.0 mode.
  • Insufficient space: If the drive cannot accommodate more data in the available space, it will also cause write speeds to suffer.
  • SSD wear: Too many writes can cause the SSD to wear out and thus affect the performance of the SSD.
  • Firmware: The firmware on the Samsung 970 EVO Plus is outdated.
  • Bad sectors: SSDs that have been attacked by malware or have bad sectors can slow down read and write speeds.

Now you know the main reasons for the slow write speed of the Samsung 970 EVO Plus. Read on, and we will provide more detailed solutions to help fix the speed drop.
