For <$200 I set up a Rpi4 with case and 1TB SSD as a nextcloudpi server, I love it. System load is almost always <0.50 even with multiple users, but the Rpi4 IO speed is definitely a bottle neck. Really curious how much better the IO speed is using the compute module; $450 is a little pricey for a Rpi and 2TB of SSDs, but definitely a cool project!
I don’t see the appeal. Unless you relies on batteries to power your home.
Assuming 150$ for the disk that leaves 300 for a cpu, motherboard and case. Plenty of configuration avaible with better spec.
TBH, even though it looks cool, a Raspberry Pi compute module is unnecessarily expensive for the level of compute you’re getting. If you’re okay with using USB instead of SATA to connect your hard drive (which does have lower throughout and higher latency, but for a NAS of this calibre, chances are the bottleneck is the gigabit network connection anyway) and also having it look a little less elegant, a normal Raspberry Pi 4 plus a basic USB 3.0 hard drive enclosure will do pretty much the same thing for much less. Other companies like Pine64 and RockPi also sell SBCs with built in SATA connectors, and you’ll probably find them cheaper than the compute module if you shop around.
If I was gonna build an arm nas I would go with something like the odroid hc2 sbc+enclosures which are cool. but the best thing about the cm4s is that you can design your own weird carrier boards and get a bunch of new projects like this one.
as for their compute, I’ve been running a 4gb module as my openwrt router and firewall with multiple lxc containers. its been handling everything very well and have yet to run into any performance issues.
I’m running nextcloud on a RPi3… It’s slow access, but it works well enough for my needs.
FWIW Nitrokey make a similar device - https://shop.nitrokey.com/shop/product/nextbox-116
