The use of mPCIe was used as the best explanation at the time for the custom connector. While you are correct that the controller is SATA on each blade SSD, this custom solution is a PCIE design. Thanks again.

I am curious what validation you might have to prove this. Considering both the RAID controller and SSD controller are both PCIE compliant, your opinion should be validated in some way. Simply because the connector of the blade SSDs is custom, does not mean the term still cannot be used for best explanation to the reader, similar to the way one compares an Apple SSD to that of the M2.

Thanks for your quick reply- however your review states
‘There are three detachable components which are the PCIe itself and two upgradable ‘blade’ mPCIe SSDs that can be switched off for higher capacity.’
You have clearly referred to the SSDs as mPCIe which is not correct. Thanks anyway.

The review is correct and it is not stated that the SF-2281 is a PCIE controller. This package is a PCIE product, in that, it is connect d via this route. Thanks anyway.
