Obviously this's not been good-practice and you do not have any recommended
models/types ?
No, I actually never used any, only looked into them a few times, but never
found anything that I really liked.
Another thing though that could work, especially with newer boards, are NVMEs
in m.2 format. The last server boards that I looked into and eventually also
bought, have m.2 NVME slots.
But they are very "practical" though :)

Thank you Aaron,
this atribut "small" is blocking point ... like you said it is hard to find
sata disk under 250G
I was also thinking about 2 x sata-dom 32G/64G for zfs boot ? Does it make
any sense (performance/relayibilty-wise?
SATA DOMs need to be considered carefully. If they can last long enough, then
why not. But if they are just cheap SSDs that will wear out fast... well.
Ok , today I'm gonna install PBS on 4x2T (disks, not ssds) zfs raid10 and create
one new dataset in /rpool -> /rpool/databck ... So , the PBS itself and
datastore will reside on the same pool ... Then I'll make some copmarison tests
(backup/restore) and report back some relevant results ... I'd like to avoid PBS
on its own pool because this SuperMicro 721 case has only 4 disk slots , a
additional ones (2) have to be connected directly to MB ...
'till then

A PBS datastore is just a directory somewhere.
If you set up the system on a RAID 10 and want to use that as well for the
datastore, I would create a new ZFS dataset for the datastore. This allows you
to change certain ZFS properties on that dataset specifically.
There are a few things to consider if you want to have the OS on the same disks
as the datastore.
How fast are the disks? HDDs or SSDs?
If they are HDDs, then having the OS on separate disks is a good idea because
HDDs will already be having a hard time to provide the IOPS for decent
performance. If they are *decent* SSDs, you should be fine.
No idea how easy it is to get stuff in Croatia, but this should give you some ideas:
https://geizhals.eu/?cat=hdssd&xf=2028_256~4643_Power-Loss+Protection~4832_1~4836_2&sort=r
250 GiB is plenty of the OS, but anything smaller is hard to find or of dubious
quality ;)
Cheers,
Aaron

I'm planning to use SUPERMICRO 721 box (4 x 2T sata) as PBS
So, if I create zfs10 raid as boot drive , I have no more disks left for
datastore, right ?
BUT, is it possible to make directory on this / boot drive i.e. /mnt/datastore
and attach it as datastore ? Is that a way-to-go and is there any
disadvantages against separate 2 x 240g ssd as boot and 4 x 2T sata (zfs raid
10 ) for datastore?
Actually I'ma having hard time finding 2 x 2,5" small sata drives for boot ....
Thank you very much in advance
