What Are the WD SN550 Changes?

Western Digital's WD Blue SN550 budget SSD is a well-reviewed and popular NVMe device that has regularly appeared on various sites' "best SSD" lists since its release in late 2019. Western Digital will replace the NAND flash and update the firmware in the WD Blue SN550 starting June 2021, which will negatively impact its performance when the SLC (Single Level Cell) is depleted.

Western Digital has confirmed that it changed the NAND flash memory in one of its most popular M.2 NVMe SSD models, the WD Blue SN550, which crippled writing speeds according to several reports, leading to a 50% performance hit. NAND flash downgrades likely won't affect the average consumer, as users are unlikely to be constantly filling up 12 GB of SLC cache. However, if you move a large number of files, such as 4K video files or large compressed archives, you will definitely notice a decrease in performance.

Need to Do Western Digital SN550 Change

Because of the 50% drop in performance due to WD SN550 change, many users want to replace their WD SN550. Apart from this reason, there are some additional reasons as follows:

  • Low storage capacity: If you find that you are frequently running out of storage space on your WD SN550, you may need to replace it with a higher-capacity SSD.
  • Slow performance: If your WD SN550 is running slowly or experiencing frequent crashes or errors, it may be time to replace it with a newer, faster SSD.
  • Upgrading to a better SSD: There are many newer and faster SSDs on the market, and if you want to take advantage of the latest technology, you may want to replace your WD SN550 with a newer model.
  • Compatibility: If you are upgrading other components of your computer, you may need to replace your WD SN550 SSD to ensure compatibility with the new components.
