say to edit the subject line when responding so that it is
descriptive of what I am going to write. But I don't know
how to do that after I click reply; unless I start a new
thread. Actually, as I am typing now I don't even see the
subject line. If someone wants to explain how to do that I
will do so in the future.<br>

It looks like you are tripping over options on gmail reader
(guessing from your email) -- not something I use, and looks a bit
tricky.<br>
Any one else on this ? I'll post on HT web site as advice.<br>
<br>
AND even if you can't change the subject -you can trim unrelated
posts from the digest - please.<br>

<div class="gmail_default" style="font-family:trebuchet
ms,sans-serif">Rich, I looked at the Drobo website and they
do have a unit for $350. I am trying to keep costs down but
am willing to pay what I have to within reason to get this
done properly. The QNAP unit I included a link to sells for
$164. As I started reading on the drobo website it just
seems like there is a whole world of external drive systems
with many concepts that I am not familiar with. I do
understand what you are saying when you say that it might be
better to use more smaller drives rather than fewer larger
drives. I had not previously thought about that. (Maybe I
should get a four or five bay unit instead of a two bay
unit, and get four 5tb drives or five 4tb drives instead of
two 10tb drives. On the other hand, though, I would think
that the more drives one has the more likely that one will
go bad on any given day.) They are out of stock of the
Drobo 5c on the manufacturer's website but I do see some
similar models on ebay.<br>

Actually have more smaller drives are less likely to fail -- AND the
added trick is to buy drives over a time so each from different
batches.<br>
And added approach, I have not tried, is a mix of manufacturers. <br>
<br>
as for the unit you mention, and many of the RAID units, all drives
must be of the same size -- I'm not sure how this applies to all
drive units.<br>
There is plenty online about doing that -- RAID6 seems to have part
of the answer.<br>
<br>
And yes, you're better with 4x5tb then 2x10 -- and BTW, 4x drives
lose a smaller amount in the RAID system (the basic technology we
are talking about) -- Rather then mirror (called RAID1) - RAID5/6
-- sorry but I can't give percentages, the easy one is that
mirroring gives you the size of one of the drives - the other raids
use less for redundancy.<br>
Here is some of what I'm saying to be more visual, however knowing
helps, for practical use you don't need to know the details:<br>

Aside from normal backups and years of images, and other projects --

<p>Direct connect or Network is a choice that depends on how you use
it and that's more of a personal choice.</p>
<p>Also, as was just pointed out to me, that effects Drobo -
evidently Drobo directly shipps units from China and are being
effected by the Coronavirus -- no idea who else or for how long
this will be an issue -- personally I'd pick the best unit for my
needs and wait a bit.<br>
