Sorry for bringing up an ancient email, but I saw that it was topical
again recently
Can I recommend the PCEngines APU devices for your requirement. They
aren't as cheap as the various "PIs", but they have a ton of horsepower,
MPCIe slots and SATA ports. Power is low, but not super low (5-10W). You
can use them with a decent SD card (PCEngines have some that can be put
into SLC mode for better wear resistance) or use a full MSATA SSD (or
the SATA port)
I love them!
Other stuff which has caught my eye:
Odroid XU4
Odroid HC1
or USB3 to SATA adaptor on something with USB3 such as a Rock64
It's easy to spend more money than an APU2 though...
Good luck!

Hello Alan,
1) A Low Power server for my local Amateur Radio club.
10W or less with at least 100Gb of storage and affordable.
Mission: Keep the electricity bill down.
Why would you need 100GB of storage? That's a LOT. I've been running
many a Linux host on 32GB of disk/ssd (or much less) for a very long time.
2) The Codec2 repeater, on a mountain top somewhere.
But needs to log perhaps 1Gb per day of received WAV files.
I've been following your nifty little project for a few weeks now.
Thanks for sharing it! I might try out the code myself but why do you
need to log that data? FM repeaters don't usually record their
transmissions. Regardless, don't archive in WAV... archive into MP3
or OGG and then rotate the files to off-site storage via the
Internet. If you don't have Internet at the site, then just lower
your archive retention settings.
3) Be a General Purpose Linux box with all the development apps
and a remote GUI interface eg. Joe Taylor K1JT compiled and
tested the KVASD ARM binary on the BPi box here then made
available the ARM binary for WSJT and WSJT-X.
Requiring GUIs on a Raspberry Pi increases the storage required but
not by more than a few GB. It's your choice if you wish to do this on
your remote repeater site.
So, I'd dearly like to run a Real Pi but without a High Speed Disk interface
on a real Pi, I have no reason to buy one. Yes, I have an original, a 256Mb
one. SD cards broke (wore out) in days. That's why in about 2014 I went BPi
and have never looked back.
Nothing you've mentioned above cannot be easily fulfilled with a USB
attached disk/ssd. The Raspberry Pi line of SBCs have supported
USB-based boot for some time (no longer requiring a microSD card) and
the USB2 bus (while not super fast for today's standard) will easily
meet your I/O performance needs.
To your "wore out" issue, this can be a problem for systems that are
abusing the the SD card (heavy writes all the time). This is easily
mitigated using a mixture of tmpfs (RAM drives), better logrotation
schedules, etc. You can see what I recommend here:

Keep smiling guys. I appreciate your thoughts.
And yours too!
Current models with SATA on the SoC:
Banana Pi M2 Ultra
Banana Pi M2 Berry
Very nice hardware and I've considered upgrading but I've never been
able to justify the high performance, lots of I/O possibilities, etc.
I just really don't need it. The real differentiation is the
community support. Raspbian (OS) and the Raspberry Pi (hardware) have
excellent support, are constantly updated, improved, etc. The Rpi 3B+
still isn't using the fastest ARM processors, offer the best I/O
possibilities, etc, but it was never intended to... mind you it does
give you 4x ARM8 cores @ 1.4Ghz, 1GB of RAM, GE & 802.11AC wifi, and
BT 4.2 for $35. That still staggers my mind.
Anyway... up to you. Now back to the CODEC2 show!
