SanDisk Ultra+ SSD Manual Firmware update version X2306RL

SanDisk has released the ISO firmware images to allow SSD firmware update on operating systems that are NOT supported by the SanDisk SSD Toolkit. Each capacity drive has a separate Firmware ISO. You MUST use the correct firmware ISO for the capacity SSD you have installed.

WARNING: Applying the wrong firmware ISO to your SSD product will render the drive unusable! Please confirm the capacity of your SSD product before proceeding with the firmware download and update.

Note: The SanDisk Ultra+ SSD has two different model numbers. There is no functional difference between the two different model numbers. The Label on the SSD itself will always show SDSSDHP regardless of the internal model number. 


Please verify the model number  using one of the methods below. Do not use the SSD label to verify model number. Additionally you will need to know the capacity of your Ultra+ SSD and select the corresponding download below

In the title you are calling the firmware 2306. The iso files have the number 2316. What is correct?

X230 is the correct version. The post has been updated. 

Is it still possible to have the 2316 version?

It seems to have solved a problem for Hellsfoul, and I’ve a similar problem and configuration than him (HDD “randomly” detected on a Dell GX620).

Would also love to have 2316 back or newer to fix same problem on thinkpad, quite annoying having to restart on every cold boot.
