This is very disappointing, i earlier returned the sabrent rocket 4 plus but samsung 980 pro wasn't much better (maybe +30%) in terms of sustained write speed.
sustained write: 0.92 GiB/s (not even close to the specifications).
Not sure if the issue is software (samsung has still not provided a proper driver for it) or if it is some hardware issue like how adata screwed over their costumers.
I would prefer not having to return another SSD.
A New update of the firmware for the 980 Pro finally correct the problem !
Need to Open/Close Magician multiple times to get the Update on it.
Last Magician Software update on middle of march, implemented the "Full Power Mode" function, and i left enabled it (Which makes my 980 Pro hotter, without performance gain)
But the firmware update won't works with it, every time i get an error on updating firmware.
I disabled the Full Power Mode function, restart, and after a reboot, i finally get the update working.
Now i'm on the 3B2QGXA7 Firmware and my Speed is finally correct, hope, it will stay like that!
Do you know how to install this firmware update in a RAID setting? I have 2X 1TB 980 PROs in RAID 0. Most of the Samsung Magician features are not supported. e.g. if I select 'Diagnostic Scan' it reports 'The selected drive does not support this feature'. If I click Update it only says 'You are currently running the latest version of Magician' (which does nothing). Underneath that is a dark grey empty rectangle rather than a link to download firmware. However, it doesn't say 'The selected drive soes not support this feature'.
I have downloaded the firmware update from the link in the website rather than use the Magician software, which is an iso image. But I am not sure what to do next.
