I was just being goofy. I didn’t mean to come off as a smart***** if I did.

You didn't.

I will have to use a stopwatch because with the just the counting "One one thousand , two onethoustand " method, with my current 512 GB SM 951 ACHI in slot 3
I am about 30 seconds from pushing power button on computer to Desk Top

OK so just got the Crest and the two EVO 970's last evening, so I will be installing them and report back.
It will be a few days before I can do the installation as we are too busy with some new construction projects on the ranch, should be able to get to it by this weekend

Great. I have been running my two drives some days now like full time as usual and no problems so far.

But my boot times are not impressive. I today I got like 20 sec from pressing the power button until the chime and then a minute until desktop. But I believe 40 seconds from chime to desk is normal for me. I see no benefits there from a faster drive and the crest card. I have a lot of extra stuff that needs drivers like synths and gear. Perhaps that slows it down.

This is an older article as to what happens when you start up a Mac but it should still be relevant today

OK got some free time this afternoon So I installed the IOCrest and the EVO 970's
First I have the say the "QUOTE" User Manual for the Crest is a total joke Gives absolutely nothing about how to install the drives on it.

So it took several mounting attempts to figure out the how to position the little spacer nuts that come with the Crest so as to get the EVO blades riding parallel to card surface slightly off the card surface. The spacer nuts (2 of them) are larger diameter one side and smaller diameter on the other side (the smaller side that slots down flush into hole in the card) and threaded on both sides so you have to use one screw to secure the spacer nut to the card and one screw to secure the blade to the spacer nut .....NONE of which is stated in the silly manual which is simply a spec. list. On my first attempt I did not use the spacer nuts at all, and the card sat at a slight downward angle from the connection slotted blade side to the other end with the 1/2 circle screw side (WHICH did not look correct to me) So I had to play with using positioning the spacer screws to finally get EVO parallel to the Crest surface and slightly elevated off the surface at both ends ....

Ghost ??? perhaps the above is obvious (it was not to me at first) but did you use the spacer nuts and get the blades sitting exactly parallel to the Crest ? Because if not I wonder if the angle could be causing a connection problem ? Just a thought or if you did It could be a bad Crest unit.


Once all that was done I installed the Crest into my Mac into the #2 slot from the bottom (16 lane) and moved my PTHD card to slot 3 and my SM951 boot drive to slot 4 (top)

I plugged all connectors back into the Mac and fired it up ( this first boot took about 40 seconds )
I have now started from power on to desk top, 3 times and it is still about 40 seconds (which is 10 seconds slower then before installing the Crest.

The New drives were not showing on the desktop but were showing in Disk Utilities so I erased and formatted them APFS and bang there they were . I transferred a couple PT sessions to one EVO tested and it worked fine.




So first thing I did was transfer my PT session file folder from my HDD to one EVO it was a 70 GB file and transferred fine. I have tested about 6 PT sessions so far so good

Now I am in process of transferring my FCPX library folder which is a 189 GB and it is going fine so far

I will report back when I done some more PT and FX mixing and editing But pretty good so far

Yes, the directions are non-existant, but I did figure it out and was going to post photos after I got it up and running. Mine are parallel to the Crest. It turns out I did have a bad card. The new one is in and working beautifully. First thing I did was move a large file from one 970 on the Crest to the other 970. Bam, done. No crashes, PT working great.

Here are some photos showing how the support under the ssd card should look.
One screw attaches into the brass riser from the back side of the card and the second screw holds the ssd card down.

Adds to the trust, right? seriously, good that you got a working one
