For those not aware, the Samsung 840 evo drives had a flaw where old data written to the drive would be very slow to read.

Samsung finally released the DOS/linux/mac .iso version this fix here.

iso:

install guide:

zip:

Does anyone know how to properly install this to a bootable USB drive? Samsung's manual intentionally defers this to other sources.
I need to flash my macbook but don't have an optical drive.

I do have an optical drive, but I always do Samsung's firmware updates using Magician in BootCamp Windows.

Blame this need for using MS-DOS boot CDs on Apple, by the way, not Samsung. It is the same reason TRIM doesn't work on third party SSDs.

As Oskar Groth of Cindori Software writes:

Have you ever wondered why disk manufacturers like Corsair, Samsung etc. has never written a Trim driver for OS X? Or why they never offer firmware update software to OS X? (The only firmware updates they offer for Mac is a MS-DOS boot CD)

The reason is that Apple is keeping the AHCI driver private, making it impossible for anyone, even these big companies, to create a driver for SSD’s.

Thanks - my current plan is to just flash it in bootcamp. That will definitely update the firmware.

My question is this: If I have a small windows partition (10gb or whatever), and the rest of the drive is on an HFS+ partition, will the samsung performance restoration software still fix all of the old data? (Since it will be on a different partition and file system that the executable is running)?
