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.

We are new CRUCIAL SSD user
We have recently purchase several SSD as M550 1024GB, M500 mSATA 480GB and MX100 512GB,
Somme of those SSD will be only used into usb case,
How test those SSD without installing OS on it ?
We are using a CENTURY Copy pro HD Stand to test, Erase, Duplicate, etc (and more) our HD/SSD
The M500 mSATA 480GB pass "hd check" test without issue
The MX100 512GB and M550 1024GB miss "hd check" test
we are supose that the CENTURY Copy pro HD Stand "hd check" test is not compatible with those CRUCIAL SSD
to find it out, we'd like to know if you have a SSD test utility software for a stand alone use ?
as the "stand alone"  .iso software that we use to check memory module on a dedicated boot USB Stick

Hi Blues93,


We don't have a test utility software available.  You said you wanted to test the SSD drive before installing an operating system, is there any specific reason for this?


Are you having issues with the drive when you're trying to install an OS?  Please let me know if you have any other questions at all and I would be more than happy to help.
