APPLE TIME CAPSULE 5th Gen HDD

what HDD inside time capsule :

I found various wrong idea about the HDD inside a time capsule. I opened a 5th Gen AC time capsule and found seagate barracuda with SATA III 6GB/s interface. Model number ST2000DM001. All latest barracuda are with exact same spec @ 7200RPM & 64MB cache, just the cache size is available up to 256 now.

inside time capsule it gives 25/27 MB/s megabyte per second read/write speed via 5G AC wifi connection @1300mbps. This is the maximum performance of the HDD inside time capsule. Ethernet port gives same speed because wifi speed is similar as mentioned above.
