I'm not achieving the benchmark speeds I expected.

Performance can vary depending on hardware configurations, software, and more.  These simple steps will ensure your SSD is configured correctly:


1. Check what SATA speed your motherboard supports (SATA-I, SATA-II or SATA-III), as this will limit the potential speed of your SSD.

2. Ensure your system is set to run in AHCI mode and the latest AHCI drivers are installed.

3. If it's a desktop, try using a different SATA  port and SATA cable.

4. Ensure the latest firmware is installed on your SSD.  You can find the firmware updates here.

5. Ensure the partition on the drive is aligned correctly. If you cloned your drive, we suggest a fresh install of the operating system.

6. Disable superfetch, drive indexing, and defrag.

7. Update system BIOS, chipset drivers, and SATA controller drivers.

I'm still not achieving the benchmark speeds I expected... by far!

Since you are commenting on an article on what to do to achieve expected speeds, can we assume that you have already checked all items on the list above and made sure that you have everything configured correctly and up to date? If you have, then the next step would be to follow the steps at the end of this article, to ensure that the drive is given sufficient idle time for Garbage Collection and the other internal maintenance features to run on the SSD.


If you have done all of the above and you still are not seeing the expected speeds from your SSD, please contact support for your region for more detailed assistance, specific to your situation and system.
