Ive been looking in to buying 5th Gen Time Capsule, but I can't find any recent reviews. So if you are still using one, with latest wifi devices, what are your wifi speeds on 5Ghz band? I live in an apartment, so I don't need the range.
My Internet connection is 100 Mbps, so these numbers are just fine for me. Been using this TC for years and it has always been rock-solid reliable (except the HDD has failed and been removed).
Now, above I'm talking just about WiFi throughput -- if what you're really asking about is data transfer rates via Time Machine or SMB, it was slow... like 10 MBps (Mega Bytes per sec) at best. It appears that the processor in the TC is the bottleneck (it's not the HDD itself).
