I’ve got the exact same problem new ssd errors when tryin to install…. I’am really frustrated with it, (I’ve updated the firmware btw, didn’t help)
Go back to your vendor - sounds like you purchased the wrong SSD. You didn’t provide any specifications but your SSD must be Serial ATA (3 Gb/s). Since you’re having trouble it isn’t. It’s either slower (most likely) or faster (possible).
