Samsung Updates Magician to 4.3 – Enables RAPID on 840 Pro, Encryption on 840 EVO



Those of you lucky owners of Samsung SSDs may have noticed that an update to version 4.3 was recently pushed out for Samsung’s Magician software utility. The update enables a couple new features for owners of Samsung’s 840 EVO and Samsung’s 840 Pro.


Starting with the Samsung 840 EVO, Samsung has finally released a firmware update (EXT0BB6Q) that now enables TCG Opal / IEEE 1667 encryption support for the SSD. This now makes the Samsung 840 EVO compatible with TCG Opal certified integrated management software and the combination of TCG Opal / IEEE 1667 gives the Samsung 840 EVO compatibility with Windows 8’s eDrive (Encrypted Hard Drive) feature, which leverages the SSD controller to encrypt the entire SSD without any impact to CPU orpower consumption. Samsung had promised a firmware update to enable these features back in July when the Samsung 840 EVO was announced; however, it wasn’t available until recently.

If you own a Samsung 840 EVO, you can go ahead and update the firmware via Samsung’s Magician 4.3 software or via USB. Both files can be found at the Samsung website here.


Alongside the good news for the Samsung 840 EVO, the Samsung 840 Pro is also getting some great news as well. The update to Samsung’s Magician 4.3 now offers RAPID mode (also covered in our review of the Samsung 840 EVO) to the Samsung 840 Pro, a feature previously only available to the Samsung 840 EVO. Above, we quickly tested one of the Samsung 840 Pro 256GB SSDs we had on hand and as you can see, we’re able to reach ~1GB/s reads/writes off a single 840 Pro running off the SATA interface!

If you’ve got a Samsung 840 Pro and you’re ready to take advantage of what RAPID mode has to offer, you can go ahead and download Samsung Magician 4.3 here.


  1. I am very disappointed that Samsung didn’t make the TCG Opal support available on the 840 Pro. All along they said they would update the firmware to add this capability, but now they only release it for the EVO. We have 840 Pro’s that are less than a year old. Are we expected to replace them all with EVO’s now ?

    • Yeah, it’s a bit disappointing it’s not there yet as well. Feels like it should be since the 840 Pro is more oriented towards professionals who might want TCG Opal/eDrive support.

      I think the main reason for implementing it first on the 840 EVO though is because it was promised to us since July when it was launched. They told us originally it was going to come out within a month or two, but instead it took about 5 months.

      I’m sure it’ll be out on the 840 Pro in due time though seeing how RAPID has already “trickled down”. Somehow I can’t see Samsung alienating their flagship SSD buyers.

    • I have a samsung 840 pro and my bios(desktop) doesn’t have hdd password option, so class 0 is useless to me and no other way to enable h/w encryption ..what a waste :(

  2. Better late than never, but it’s impossible for you to have actual benchmarks of 1GB/s over a 600MB/s interface. Sorry, RAPID can’t do *that*. That benchmark is clearly accessing system memory instead. As an analogy, believing that you’ve achieved 1GB/s over a 600MB/s interface is akin to saying you travelled 100 miles in an hour without going over 60mph.
