Can you make a video on installing dual 2.5 SSDs on a 27 inch 2019 iMac. This is besides the PCIE SSD. I am talking about having a tray that houses two 2.5 SSD. Thanks in advance.
Your system only has one SATA port thats it! So a single SATA drive is all you can connect internally. Why are you trying to do this?? Fully explain!
You can use something like this: Dual-Bay 2.5” to 3.5” SATA Hard Drive Adapter Enclosure with RAID. Obviously all the implications of using third-party SATA drive in the iMac, striping 2 SSD’s (if you choose to do that), etc. still applies, but basically you have two drives one SATA port, you need a RAID controller, I’m pretty sure there aren’t any port multipliers that would work in this situation (and even if it did, what the iMac would have to say about it), or another way of attaching them as you might with other scsi devices.
