@scottalanmiller you are calculating wrong.
You claim that the NAS solution cannot be only 5TB because of growth of data. This is wrong. If the raw data to be stored is 5TB, then you need more than 5TB in AetherStore as well to handle the multiple copies that provides the RAIN.
You cannot compare size to size. That is the wrong math.
If you need to protect 5TB of data, you need 20TB of free space in the AetherStore RAIN array, more or less, to get the 4 copy redundancy that a standard install provides.
The NAS only needs 5TB. Now the NAS does not have 4 copy redundancy, so you need to buy a second one at least and replicate for redundancy. The NAS does not need 4 copy redundancy because unlike desktops that go offline at random intervals, the NAS are supposed to be always online in a fixed location, so this means a 2 copy redundancy is likely sufficient.
Conversely, if you only need 5TB total on AetherStore, that means you only 1.5TB or so on the NAS.

Depends how you look at it. For 5TB usable you need 20TB raw in either case. It's four copies both ways.

@scottalanmiller Normally a 128GB SSD drive.
So you'd need 40 SSD's at 128GB free space for 5TB usable storage. Which means you either need more SSD's in your organization, or to get larger capacity SSD's.
Which approach would be better depends on if SSD prices take a dive, or your business grows and gets more equipment to add to the store.
This only gets you one copy of data, not two or four as listed in Scott's example. For Scott's example, he'd need 160 machines with that amount of storage.

I just have a hard time believing that EVERY machine in the company is on an SSD as it's ONLY drive. Even if you upgraded to SSDs, I'd assume your machines didn't ship that way, which means you should have spinning drives in them. Format them and just use them as data drives. Most ship with a minimum 500GB and it's still common to have 1TB drives in the machines. There's storage there too.
Why would you assume that? I pull the drives out to reduce power consumption and cooling costs.
What do you do with them?

No, it is not 4 copies either way. I specifically called out that point in my post.

Not that it's been that many - around 10 total - they are sitting on the shelf. A few of them have rotated back into use in machines that had drives fail. Let's assume I have 6 left over.
yeah I could deploy those 6 and get 3 TB of total RAW space, or about 500 GB at quad redundancy.
After that I would have to spend a lot more on purchasing new drives than just purchasing a NAS and drives to get my 5 TB of quad'ed storage.

One of my main concerns was the fact that Aetherstore is basically ONLY local backup. So no offsite.
I guess you could backup the mounted Aetherstore store, though. So really no different than a NAS.

Correct. Both are local or remote. You can put AetherStore remote too.

Sure, assuming you have a second sight or a bunch of storage available in a server at a colo.

In either case you need a place to put the storage.

@Dashrender said in Why Choose AetherStore Over a NAS?:
My machines mostly still have HDDs in them. 500 GB drives. Probably 300+ GB free. If I ignore the laptops (yes I know Laptops can be part of it.. AetherStore specifically tested their coming and going as part of their tests), I have around 50 machines. Assuming only doubling of the data, that would provide me with 7.5 TB of space total.
Now the question is, what's the performance like?
A lot of the performance comes from the main access node(s), so if those have fast drives it can make a big difference, or should.

The NAS does not need 4 copy redundancy because unlike desktops that go offline at random intervals, the NAS are supposed to be always online in a fixed location, so this means a 2 copy redundancy is likely sufficient.
I addressed all the parts of this, I thought. The AetherStore portion with this "So we are going to assume that for the size that you want that you have the necessary capacity in your organization, which is pretty common. If you need to buy disk drives just for AetherStore to have capacity, you will need to work out the numbers far more aggressively."
The NAS does not need four copies, but to be roughly equivalent it does. Because the NAS approach is four copies in two nodes versus four copies in four nodes. There is more protection, not less, in the AetherStore approach. The RAIN rebalancing system is far more powerful than a NAS full sync replacement one, too, and far less manual.
If you feel that the NAS approach with two copy redundancy is fine, that means that you are running two NAS devices, each with just a single drive, no RAID at all (other than a network RAID 1 at best.) That's an option, but I know of no business that would be happy taking on the pain and expense of buying NAS devices only to have to fully rebuild them with any drive issues.
It's a stretch to really even think that you'd go with a single drive (or RAID 0) even on a secondary NAS device, but assuming that this was okay it would mean triple redundancy. You could do the same with AetherStore and turn it down to triple replication as well. Four is just a starting point and it matches the minimum I've seen from any business that has put in two NAS boxes that replicate - it is assumed that you will at least have RAID 1 on each, resulting in four copies for the NAS.
I think that most companies would feel far more confident having triple mirrors on AetherStore compared to two NAS devices with one of them having no RAID at all, but a survey would be more telling.

No, it is not 4 copies either way. I specifically called out that point in my post.
If you have examples of companies that are concerned enough about their data to require redundant NAS units but don't care if their have RAID on them, I'd be very interested to learn about them. This is quite literally the first mention of this approach being used that I've ever heard of. I truly mean I've never seen a company go so far as to buy a second NAS but be okay with skipping the RAID in it. I can see the logic that would drive someone to consider that decision, but have never seen anyone even mention considering it before. And certainly never to do both nodes with no RAID.

Stop making f[moderated] s[moderated] up and answer the point that I raised OK with a company feels like which is what you're trying to say right now. I specifically stated the cost of getting juniors versus the cost of either store for the same set a space you were using the wrong f[moderated] math

Would you? The base cost of the NAS units with no drives at all is $500, roughly. And the NAS units have to have a lot of new, big drives to handle the capacity.
With AetherStore, you have the monthly cost but not the $500 capex spend up front and you only need to buy drives to make up the difference between what you have currently and your 5TB plus redundancy.
So with the NAS, you need to buy 20TB of drives for 5TB usable (assuming normal RAID usage.) With AetherStore you need 20TB - Your current capacity of drives. If you have 10TB now, you need only 10TB more. If you have 18TB now, you need only 2TB more.

5TB Raw on AetherStore with quad redundancy is 1.25TB usable space.
If you had 1.5TB on a NAS, that would imply that you are comparing quad copy, quad node AetherStore to a single NAS unit with no RAID and no node redundancy. So not even kind of comparable.
For a single NAS to have any RAID protection on that, you are up to 2.5TB minimum. If you want a second NAS to get minimal node redundancy, you are up to 3.75TB minimum. To be on par to any degree with the AetherStore approach you need 5TB minimum with the NAS.
Both have their benefits and caveats, but overall, the reliability is roughly the same only when the redundancy is the same. The NAS has the advantage of local rebuilds with the drive replacement and the "design" to be always on. The AetherStore has the benefit of auto-rebalancing during a node loss and multi-node rebuild of a replaced failed node plus twice the nodal redundancy.
In this price range, we are talking about prosumer, non-redundant component NAS units. The uptime of these is not really different than a normal desktop. Good policies around desktop management can alone make all of the difference as to overall reliability.

I used my specific example as a way of showing it wouldnt be cost effective... I currently have 3 TB at four copies of data... So sure adding two more TB would require me deploying four 2 TB drives.. sure those are pretty cheap. I guess there could be cost savings there... Maybe.

Or likely just two 4TB drives. Remember they don't have to all be equal.
But let's assume you need 4x 2TB. That's WD Red 2TB at $87 for a total of $348. That's over a thousand cheaper than the NAS solution up front. Any drives you add over the next four years would grow that potentially and the cost of adding one or two additional drives to grow in a few years would be trivial.
The breakeven point is somewhere around five years in that case. If you don't need to grow, the NAS approach might be cheaper around five years. But the AetherStore approach is far more flexible.

The reality is that my replacement machines will have even smaller Drive in the currently do with new SSD drives going in there a 256 gigs instead of 500 gig drives that are in there now

If you look at the cost today and consider that your desktop buying habits would likely change if you had AetherStore, it is easy to see how companies might often opt for the nearly free additional 1TB spinner in every desktop and get 250GB of protected storage per desktop added to the environment. If you are planning for that design, it can add up very quickly and economically.
