Samsung 840 EVO - Second affempt at firmware to fix the slow read issue

So, I have a Samsung 840 EVO... from what I understand the first attempt to fix the slow read issue with the drives didn't work, so they released a new firmware.... at least I think they did.

http://www.samsung.com/global/busine...downloads.html

I am looking at the ISO-bootable firmware updaters. It's listed as "Apr. '15", which dosen't really help as there is no year listed. After a bunch of Googling, it APPEARS to have been released in April 15, 2015, and this is the new firmware that is supposed to fix the read issue for good, right?

From what I understand, this firmware will basically peridically move the data around so it is always "new" to fix the problem with old data slowing down. But the description worries me:

"Supports Advanced Performance Optimization in Magician 4.6"

Does this mean that I need to use Samsung Magician software and IT will perform the periodic refreshes? Or is it optional and the firmware alone will do it? Reason being that I have two 840 EVOs in a RAID0 setup, so I cannot access them through the magician software, and can only update the firmware by temporarently disconnecting the raid (as it's my boot drive) and running the updater on both of the drives off of a boot disk.

I think it means April 2015. There is a quote mark before the 15.

Yes. You need both the updated firmware and the Magician software to do the optimization. At least, that's the way I understand it.

That's about all I can say since I don't own any EVO drives. I do have an 840 Pro, though.

I have several Samsung SSD's. Use Magician to do the firmware updates. Due to the limitations of the SATA 3 bus speed running those drives in RAID 0 is somewhat pointless.
