RAID Question

I was playing around with software mirroring on a Windows 10 box with two SSD drives. There was no increase in throughput between a single drive and RAID 1. I was under the impression RAID 1 should have increased the throughput because there were two drives filling the pipe as opposed to just one but it didn't change much. Why wasn't RAID 1 better?

Well.... I was under the impression that no matter what RAID level you use that adding spindles (drives) would increase the read throughput. You are saying that is not the case (at least not with RAID 1)? That when you read information from RAID 1 it doesn't get some info from each drive thus increasing the overall read throughput?

A lot of what I am hearing is "You might", "Depending on Implementation", "Possibly". I think what it boils down to might be more like "You won't get a read performance increase on RAID 1 simply because it does not do striping. Striping is were you gain performance by having multiple disk fill the pipe".
