SanDisk Extreme SSD Firmware download for MAC and Linux and PC

SanDisk Extreme SSD firmware version R201, Manual ISO download for MAC and Linux and PC

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.

Step 1:

Verify the capacity of your SanDisk Extreme SSD and download the corresponding firmware ISO

SanDisk Extreme 120GB SSD
120GB R201 Firmware ISO

SanDisk Extreme 240GB SSD
240GB R201 Firmware ISO

SanDisk Extreme 480GB SSD
480GB R201 Firmware ISO

Step 2:

Burn the saved image file to a CD/DVD with another software application then boot from the CD and perform the firmware update.

a.     Restart your computer.
b. For PC and Linux - Make sure the CD/DVD drive is the first device in the boot sequence defined in the BIOS, and restart your computer with the newly created CD/DVD boot disk inserted. 
FOR MAC:  With the firmware disk inserted Press and hold the “C” key while the computer restarts.
c.      After restart, your system will boot to the SanDisk Firmware Updater
d.     Select the drive you want to update from the list displayed.
e.      Press ENTER to start the update.
f.      When the update is completed, Press ENTER to shutdown computer.
g.     Remove the boot CD/DVD from the drive and restart computer.
h.     That’s it…finished!

Thanks for that. Much appreciated. May I ask, does the firmware render any OS or data already stored on the SSD unusable? That is, is the process in any way destructive? Thanks.

No response yet, so I went ahead anyway using Linux CDR boot disk with ISO burned at 16x. So far, so good. If one follows clear instructions there is no problem. Simple text-based installer asks three times if you’re sure you wanna proceed. This is to avoid loading the incorrect SSD storage capacity firmware, as is clearly explained. I keep reading about other brands’ convoluted-nightmare firmware update procedures. Not so with Sandisk. This was about as straight-forward as it gets. And it appears there has been no unwelcome effect on OS or data stored on SSD thus far.

Thanks for providing this information. As an aside, you can apply this to a usb drive using a linuxpendrive installer and update the Extreme in your Mac using a bootable USB Pendrive instead of burning a CD.

no user data is affected. that said backups should always be kept in case of a failure. 

I have done it on my Macbok pro (version macbook 5,5) Mid 2009 and activate TRIM with TRIM ENABLER all is ok !!  using SATA 2 … 

Hope this help !!

I just initiated the FW upgrade process, i got failure for USB disk in my PC. The booter saw the SSD but didn’t initiate the FW upgrade process. So i created 2 boot CDs. 1 is created by Sandisk toolkit, the other with downloaded ISO file. Sandisk toolkit created CD (total of 20MB) returned the same error. ISO burned CD (total of 10.9MB) worked. 

No data loss happened, hope this fw will improve performance, i didn’t have chance to test the SSD with new release yet.


I tried to update my new SSD 240GB installed on my late 2007 macbook pro (Core2Duo) following your step by step instructions. I burnt a CD from iso file and rebooted with C key pressed. Not working. The laptop booted on SSD. To make sure it wasn’t my CD/DVD, I tried once again but with MacOS X install CD. This worked fine.

I even tried to make a USB drive bootable with the iso file using dd command in the shell but it didn’t work.

How can I upgrade now?

you have to burn the ISO as a disk image. You cant simply burn the ISO itself to a disk or copy it to a USB drive. Below is a link that shows the correct way to burn a disk image.

This is exactly the way I did to burn the CD. I used disk utility “burn from disk image” button. Didn’t work!

Booted into SanDisk Firmware Updater okay but found two “SanDisk SDSSDX240GG25”; any idea why?  Which should I update, both?  There is only one physical drive in my MacBook Pro though.

try updateing the fisrt one in the list. once complete check the firmware version and see if it updated. 

checking fimrware version in mac

Thanks, so I don’t need to update the second one?

Hi, I downloaded a 2nd time the image file (just in case) then burnt a new CD following exactly the steps you described (using disk utility) and verified that CD was fine. At boot (C key pressed) the CD is moving quite fast but a few seconds later session screen is displayed. The laptop boots on SSD. I as previously said, booting on CD is possible on my macbook pro as I’ve tested this with OS X installation CD. So there’s something wrong with your booting software. Just to remind you, I have a late 2007 computer. Have you done test on such old laptop? So could you please provide a new way to update the firmware? TRIM is not activable and I want to enable it.

since you only ahve one drive and if you check the firmware and it shows R201 no need to do anything more.

well as you can see from the person right above you the CD works to boot MAC. I as well just updated my SSD and I have a 10 Macbook pro.

That said you said yours is 07. I’m not sure how long ago MAC changed to intel based processors but  this CD is for x86 systems so if you dont have an intel based MAC it will nnot likely work. What processor does that have?

Thanks!  FYI, mine is a mid 2009 13" MacBook Pro running OS X Lion.

It’s a Core2Duo (intel)!

Does anyone know the step by step for a non-tech guru to install the sandisk extreme on a new macbook pro?

Any help is much appreciated.

Thank You

Are you planning a clean install of OSX or wanting to copy exactly what you have running on your MacBook Pro? Do you or have access to a USB sata enclosure?
