Don't let this confuse you with an actual NAS

To clarify slightly further. Yes this is a DAS not a NAS. Adds storage to a PC, not to your network. Cheaper because it doesn't have the brains to run itself, it needs your computer.

I have two of these attached to my QNAP box, and they have been rock solid for years. One important limitation to be aware of: unlike the NAS box itself, you cannot expand the storage on these in-place. You must move all the data off, swap in your new larger drives, and reconfigure. It's unfortunate, but should be expected at this price point.

It can, provided you have a host system with the proper software.

If you want it to be network available, your host system will need to run services like SAMBA.

Look into OpenMediaVault if you want something that's easy to manage.

I have i5-8500/16 GB/Win11 which I used as media server (Jellyfin). I never have a NAS. Can I connect this to my media server and run it as a home NAS? Can I access it from outside my home network so I can back up photos from Android phones while I'm travelling? Do I need to run separate software? I already have Docker installed in my media server. TIA.
Yes, Windows will just detect it as a bunch of individual disks and you can setup however Windows will let you from there.

While true, its really wouldn't be much of a factor that each drive is limited to SATA II speeds as no HDD would ever saturate the SATA II max bandwidth. SATA SSDs would take a hit per disk but the benefit of RAID would outweigh that loss. The real bottleneck would be the USB 3.2 Gen 1 interface.

Isn't that mostly a file system limitation, assuming you have the dip switches on this set to JBOD?

A lot of people run unRAID just so they don't have to tinker too much, but I think enabling autoexpand on the zPool when you create it might be enough.

Too expensive for what it is.
Internal RAID DASes aren't that cheap actually. I got some of these years ago at this same price, no problem with them to date, and works well in RAID 5 just attached to my always on PC.

The real question now though is whether it makes more sense to just buy a case that can house more drives internally, especially since we have 22TB per disk drives.

So as far as a DAS goes its good, I can recommend it, but is it still relevant in 2025? I'm not so sure.

Is the difference the build quality, coverage, cooling, speeds?
Probably better since its esata, so I think drives are listed individually and should work w unraid.

What you're asking for already exists. There are plenty of DAS enclosures already on the market that interface via USB 3.2 Gen 2 or even Gen 2x2 (10Gbit and 20Gbit, respectively). The QNAP you linked to is capped at 16Gbps by the bus and requires the open PCIe lanes to accommodate it, which isn't always easy to come by on these mini PCs. Most can't even physically house the card. Prior to USB 3.2, SAS would have definitely been the only way to go, though.
If it does exist, link me to one with USB 4 or Oculink. I know the DAS I linked with SAS connectors would not be compatible with most mini PCs. That is why I suggested a manufacturer make one with USB 4 or Oculink....
The one I linked is better than USB because it provides 6Gb/s to each drive. PCIe Gen 3 X8 is capable of 64Gb/s much faster than 20Gb/s.

This is one uneducated person's opinion. I, for instance, run this usb-connected to a 4-port QNAP unit to back up my data and have the backup on a separate unit.
Well, technically, any of the associated disks are separate units themselves. What is the advantage of having multiple chassis connected together assuming they all have equal surge protection?

My personal preference is to put the money in a good NAS case, say 8 bay, and fill it with older hardware lying around that works perfectly well for serving up media, but not new enough for other tasks.

Check the specs of the card.

It's capped at PCIe Gen 3 x2: https://www.qnap.com/en-us/produc...s/hardware

So while SAS can address each drive separately, the total bus bandwidth is still limited to 16Gbps.

However, let's stay grounded and acknowledge that you're going to have a hard time saturating the bus with even the fastest mechanical drives.

In that regard, 16Gbps is probably enough. And if 16Gbps is enough, then the 20Gbps USB 3.2 Gen 2x2 provides is more than enough, and USB 4 is just overkill.

Wasn't your original comment about wanting a DAS you could use with any system?

The advantage is modularity.

In your scenario, there's a lot of initial upfront investment and planning. And once the case is full, your only recourse is to buy larger drives.

With a DAS, you're only limited by the number of available USB ports.

Not to mention a lot of people are pairing these with mini PCs, which use smaller DC-DC power supplies.

I didn't know the SAS card had a bandwidth limitation, but yes if you get a proper used SAS card you shouldn't have that issue. I'm sure new mini PCs going forward will at least have one USB 4 port. If not you find one that does have that or oculink.

We'll still need drives that can saturate the bus.

Solid state can do it, but the TB/$ isn't quite there yet for the kind of files most of us are dealing with.

You're comparing a high-end eight bay NAS with a sub-$200 RAID enclosure. You can see that these are apples and oranges, right?

Not everyone wants a Mercedes, even if it is in their budget.
