Synopsis: Download the latest firmware updates and step-by-step upgrade tutorials for MyDigitalSSD Super Cache 2 mSATA and M.2 NGFF solid state drives featuring the S9 controller in this very post! (Updated with FW Ver. 1.7 on 8/11/14)

To better assist our customers, the My Digital Discount Tech Support team has created new step-by-step tutorials to walk MyDigitalSSD owners through upgrading the firmware in Super Cache 2 (SC2) 50mm mSATA and 42mm M.2 NGFF solid state drives that feature the S9 controller.

The updates found at the bottom of this post serve two purposes:

  1. To upgrade the firmware of an existing drive
  2. To over provision while upgrading the firmware of a drive

If you have an Super Cache 2 SSD running at full capacity and plan to keep it that way, DO NOT run the Over-Provisioning version of this update. Doing so will over provision the drive and there is no going back.

With that said, MyDigitalSSD HIGHLY recommends users to over provision Super Cache 2 SSDs when using them as system drives for maximum drive performance and longevity.

WARNING: Please check your firmware version before downloading and installing any firmware update. If you have a numerical version of similar or higher value to the latest update, you will not need to upgrade.

If you do not know how to check your firmware version. View our quick and simple tutorial on "How to check your SSD firmware version" (PDF, 442KB).


WARNING: The firmware updates found in this blog post are ONLY to be used with the following MyDigitalSSD Super Cache 2 solid state dive model numbers:

50mm mSATA


25mm mSATA Mini (Half-Size)


42mm M.2 NGFF


MyDigitalSSD, nor My Digital Discount, will be held responsible for any loss or damage occurred by using this update with any drive other than the MyDigitalSSD Super Cache 2 series SSDs listed above.

The updater failed to update the firmware on my 128G drive from 1.6 to 1.7.

I used the WinPE method as I do not have a default Win installation.

This is the output from the updater as I remembered it:
Current firmware: S9FM01.6
Total size: 128G
Firware is the latest!

We like to use CrystalDiskInfo, a free HDD/SSD utility software found in the link below.

is there any way to check which firmware version my ssd is currently running on?

newBuySSD - If your drive is installed and working properly then you have nothing to worry about. With Firmware version 1.8, you already have the latest FW update and cannot backtrack to 1.7.


Boris - 1.7 is the most solid and stable version of firmware for the Phison S9 controller to date. If enabling 1.7 disabled features in the BIOS, it was for the protection of the SSD and we would not recommend finding a work around.

We can request it be enabled in new versions of the firmware, but again, that may make the drive unstable for use.

Set disk password disappeared from my lenovo t440s bios after updating FW 1.3 to 1.7.

Any chance to get it back?
I know bios password can't be set if ssd switched to OPAL mode (https://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T440s-Disk-Password-cannot-be-set-in-Bios/td-p/1354729), could that be the case? And if yes, is there an utility to switch back to ATA security mode?

We're sorry to hear that you're having trouble. Unfortunately, there's no workaround we can hand you to fix the drive on your own and we would need to setup an RMA.

The good news is that our turnaround time when it comes to replacing a drive is fairly quick even for international customer such as yourself (roughly 2 weeks from when you put it in the mail).

I am having exactly the same issues as K and Adrian.
After attempted FW upgrade to 1.07 on an SC2 128GB drive the drive name changed to changed to PS3109S9.
FW version is now 8GRBOOT and device capacity is 0 GB. The utility doesn't allow for another update attempt. Do you have a solution that I can attempt locally?
I wouldn't like to RMA since sending it to the States and back is going to take quite some time.
