I’m trying to build a fleet of these. Takes a really long time to scan and syncing is sloooooow (12,000 items with 65GB, so kinda expected). But they seems to work. My whole cluster got out of whack and I had to wipe and start over (all indication is that it was self-inflicted)
These are the textbook use-case of needing “receive only” folders. They have no users typically. I am using them as tiny web servers (content needs to be pushed out, but is not generated on device)
I’m using this since few months and it works as well
Only difference I’ve attached an external HD but I had to use a “Y” cable to power it externally with the same power source used for the board… unfortunately those tiny boards have limited current on their usb ports.
(almost same scope, receive only device to backup a remote folder)
My cluster is syncing two folders. On with 12 thousand small files at 8,7GB and one with 750 files at 65GB.
Given it’s performance I would not expect 2+ TB to work well, but should work. Initial Sync takes about 48 hours, Thereafter, it seems to keep up fine. I’ve tested adding and subtracting a couple GBs with no issues.
Thank you both for your input. You are correct, its not how much data is synced . . . It’s how much the synced data changes.
I have almost 2TB in a one way sync, and I can validate that the scan process takes a good amount of time and uses a reasonable amount of CPU during the scan. The initial sync is brutal for large volumes of data, but I am confident that is entirely up to the network connection one is using to perform that first sync.
The Zsun card reader running LEDE is able to run syncthing and transfers at around 64KiB/sec. I have it running with a 64GB micro SD card and it uses 0.72W when idle (wifi connected) and around 1W when doing data transfer over wifi.
It can do around 3.5-4MB/sec writes over smb share
