Hi all,
I noted, that with the Kai nvme.sys vers. 1.5 on Toshiba RD400
you can not boot in Win7 and XP.
With the nvme.sys vers. 1.3 from Kai today you can boot in Win 7, XP on RD 400 also.
But: Connected as a co-device, the RD 400 works on XP also with 1.5 version.
This gives me the possibily, to make a 1:1 speed test for Toshiba RD 400 on
nvme.sys ver. 1.3 and ver. 1.5.
Here are the results:
nvme.sys 1.3 from Kai on Toshiba RD400 on XPSP3

As you can see: Both speeds are nearly equal.
So, for compatibility the nvme.sys ver. 1.3 from Kai from today is the better choice,
have a nice day
