well I’m about to tear in to my pc laptop for sim and VR and my Mac pro and update the m2 drive in my pc laptop for a larger one then the cmp I’m wishing to move the 2 1tb we blue SATA Ssds to the drive bay and do away with the raid 0 replaced with m.2 Ssds seperatly one for Mac OS and one for win 7/10. From my previous research I figured out that there is a minimum difference between the SATA Ssd and a m.2 SATA ssd but there is a difference between a SATA m.s and a nvme ssd . But what I do not know if the nvme will be beneficial in an old cmp using a pci card for SATA. If it is I’ll buy a couple of nvme drives for it from what I can tail for the pc is it’s using a SATA ssd m,2 drive which I already have on hand a replacement. But I saving the old drive once I clean it up as a source drive for future upgrades. That will give me a 2tb m.ssd SATA and a 1tb hdd SATA in the pc. Two 1tb SATA/nvme ssd m.2 and three 1 tb we blue ssd SATA drives with a 4tb we red for the cmp. Plus the 4 4tb we red in raid striped with pairity external enclosure plus several nas’s On the lan. The other upgrade is the GPU up to a gtx-1080 Fe 8gb, and upping the WiFi/by card to bt4 internal on mb vs pci card that’s ive been running it has 64gb ram ddr3 and dual cpus to give a 12 core 5,1 to go with the Apple 27” display I might add a second optical drive if it’s handy when I’m putting it back to get her. I’d love to use it fo vr and my swimming with dcs and xp so the laptop would be my travel rig.
