That is correct for the most part, but if you think about it writing will take the normal amount of time because it has to write to both drives simultaneously. When reading, though, the data is there on both drives so it can read half the data from one drive and half the data from the other just like in RAID0. I don't know if the performance completely reflects that but thats the theory. If I'm wrong someone please correct me .RAID1 however, i beleive has no effect on reading speed and only uses the second drive for a 1:1 real-time image of the main drive. It doesnt read off of the image drive. Can anyone confirm this please?
No.My question is, does the RAID1 configuration actually make the PC slower since everything you do needs to be done twice?
Its a bit faster yes dunno if it'll be end-user noticeable though.Theoretically the system with RAID1 should be faster for reading data because the redundant data can be read from both drives at the same time.
If RAID0 even reaches that for average usersI think it's like a 30% read performance increase, not up to the ~60% from RAID0
