Updating intel ssd
Samsung also provides firmware update tools for those who prefer a bootable USB/CD option as well.
While a solid majority of firmware updates are non-destructive and thus won't wipe your data with a reformat, the first step before performing any firmware update should still be to backup important data on your drive.
It’s not exactly scientific, but it’ll give you a good idea of performance changes with upgrades or different disks, just note the read and write speeds both before and after an upgrade, or have your friends run it on their Mac to test speeds across drives.
For example, a Mac Book Air might write to an SSD at around 180mb/sec and read at 220mb/sec, whereas a standard 5400 RPM drive in a Mac Book Pro may only write at 45mb/sec and read at 60mb/sec.
Grab the free Disk Speed Test tool from the Mac App Store, it’s a quick and simple way to measure drive performance.
The app works by creating large blocks of temporary data that are written to the drive and then read, allowing for a consistent benchmark across multiple Macs or disks.
The UI is easy to understand and there’s no frills, just launch the app and the test starts.
In this particular case, we're updating a Samsung SSD 850 PRO 128GB.
With the Magician software open, you need to select the drive you want to update (which the software should automatically have done anyhow), and then click on firmware update.
