Thanks for the links guys. I had read all but the last link, which down near the end does have some read/write rates for a Gen 2 My Cloud.
I was able to get both a 4 TB Gen 1 and 4 TB Gen 2 My Cloud for testing. Updated both to their respective latest firmware. So I was able to also answer some of my own questions used with a Mac Pro. Hope this will help someone else.
- Would the Gen 2 have faster file transfer write speeds?
The write speeds with my Mac Pro were disappointing with the Gen 1 device. I got about 35 MB/s with AFP and about 55 MB/s with SMB. The Gen 2 device was much better with about 65 MB/s using AFP and 95-100 MB/s using SMB. Read speeds with the Gen 2 My Cloud were actually better with AFP at about 95 MB/s vs 77 MB/s with SMB.
- Does Gen 2 fix the spin down/sleep problems I’ve read about here?
I read all (?) the threads on the sleep/spin down issues. Nothing I could do with the My Cloud Web Interface, Twonky, or SSH could get the Gen 1 device to spin down or sleep. Nothing worked. The Gen 2 device spins down and sleeps like it should. The only thing I did to it was set the Twonky rescan interval to 0, but I don’t know if that was even necessary (I didn’t check it set to -1). I didn’t even have to disable the NTP (time) service. So it appears the Sleep is fixed on the Gen 2.
- Any other advantage to Gen 2 worth waiting for? - such as faster USB 3 write speeds?
Unfortunately I didn’t check the Gen 1 USB 3 interface before I became frustrated with its sleep problem and took it back. Besides a few obvious differences that can be gleaned from the Gen1 and Gen 2 User Manuals, the Gen 2 is much faster rebooting, which was welcome. I didn’t have time to discover other differences.
