I've always assumed I'm built wrong. My foot isn't a foot long, and my thumb isn't an inch wide, so for any measurement that needs any sort of accuracy, there's nothing "natural" to me about the imperial system.

Do any of you have a file server in your home LAN?
If so, is it worth it?
Opinions, recommendations, etc would be appreciated.

I have a NAS configured to RAID 5 (well, two NASes) which is accessible to all devices - so my desktop, Surface, Phone, Herself's Tablets, the Surface in the kitchen, and Chromecast can all access the same files.
Is that worth it? For me, yes. It's not a "cheap solution" but RAID5 means I can survive a HDD failure without any data loss (which I have done) and being able to access important / useful documents from anywhere in the house is very handy. Just for the "kitchen surface" alone: I can add recipes on my desktop with a proper keyboard and update the NAS, then the Surface can pick them up and display them while I'm cooking. And so on.
For me, a NAS is a better solution than a file server: smaller, quieter, lower power consumption, and more reliable as well as easier to maintain.

Much appreciated.
Brand and capacity, please?

Seagate Blackarmor 4 bay, 16TB giving a storage space of 11.9TB in RAID 5 (you always lose some space with raid as it stores additional info for recovery when a HDD goes dead).
I've had this one for 7 or 8 years and it's been no trouble at all (the HDD failure was on the previous 4TB NAS which was too full and too slow). Read speeds average around 85MByte/sec; Write is understandably slower at around 35MByte/sec. Sorry, I can't remember how much I paid!

I had a file server but it sits there unused, now.
I too have a NAS. Like Griff's, it is a 4 bay 16TB Raid5 unit. It is a Raid+ with 4 4TB SSD drives. The usable is about the same as his.
I too have had it for several years and don't remember the price. The NAS came without drives, and I bought the aforementioned Western Digital SSD drives.
I am extremely pleased with it, and think you would be better going that route.

Nah, it picks up via WiFi.

Have you measured the real sustained transfer rate from the application to the network?
And the average and variation in access time? The time it takes to create ten thousand tiny files? How does it compare to an M.2 disk?
Obviously you won't have an M.2 disk of ten terabytes; I am not proposing that as viable alternative I ask the questions just to make people aware of the cost (in time) of the solutions that are capable of handling tens of terabytes of data. You can't just scale up linearly with the data volume / file count the expected time to complete, from your M.2 disk!

There's a 1 Gb (don't laugh at the size) drive; an old fashioned external drive, connected to the router. It's available on the LAN as a network drive.
It's nice to have shared space between PC's.

Interesting.
I'm looking for +10TB, though.

Cheap and ideal, since the router doesn't get turned of. Ever.
..but +10Tb is not going to work over USB. My router has USB2, but even USB3 would feel slow. If you can afford it, go OG and RAID5.

Not getting it. Why should a storage capacity of +10 TB not work over USB? The access time of large-capacity disks is not significantly longer than that of medium or small capacity disks.
Obviously, if you are going to fill up (or back up) 10 TB in one go, the sheer volume will make it take time, regardless of interface technology. With the 22 years old USB2 and its 53 Mbyte/sec max transfer rate, it will take even more time. The 4,5 years old USB 3.2 can reach 2400 Mbyte/sec transfer rate is not likely to be the bottleneck - the rotating disk is not delivering data that fast to the interface anyway.
20+ years ago, when people defragmented their disks twice a week and twiddled around with interleave factors (that was on FAT disks!), I had several friends who seriously believed the claims that they could significantly speed up their computer by deleting unused files, even if they had plenty of free disk space. A couple of them insisted that it was indeed noticeable at the user level. I tried to make them explain why it would make a speed difference if a disk block is in a never accessed file, so it lies untouched on the disk, or lied untouched on the disk because it wasn't allocated to any file. Even if my friends could not provide any explanation (they were not computer professionals), they trusted the claims in the computer magazines more than they trusted me ...
I see "+10 TB disks are slow" as a variation on the same theme. There is no technical reason why a large disk would be significantly slower. The rotational speed is the same, the arm moves equally fast, and the maximum arm movement is limited by the disk size but unaffected by coding density and track density.
Both for the FAT disks 20 years ago and modern disks, you may bring up some extremely marginal points that might, under special circumstances, possibly have a measurable effect on the speed, but never so that the user would notice. E.g. in an almost empty disk, the search for a free block (when managed by a bit map) would succeed faster than if the entire bit map must be searched to find the very last free block. Such operations make up just a tiny little speck of the application run time that it can't possibly be noticed by the user. The placebo effect can be quite strong, though (and I do know that there exists placebo so strong that it works even if you don't believe in it ).

Router and external spinning HD are from the same era as USB2.

If everything is USB2 and not USB3, and you want to access 4K 60Hz video, you may be pushing USB2 limitations. You can't assume that those limitations apply to USB3 as well. They do not.
When I got my first USB2 disk, twenty years ago, the disk was the bottleneck, not USB. But it wasn't really: In video editing, I was still on SD, 540*720 resolution, 25 fps, for which USB2 has plenty of capacity.
I am not familiar with Heroes of the Storm, and have no idea what sort of data is transported from the disk, or to and from other units. So I can't tell why it lags. The bottleneck isn't necessarily the capacity of the USB line as such, it could be the software driving the interface. Or higher layers. You may use Task Manager or Resource Monitor to watch the disk load. At the "cable level", USB2 should be able to provide a little over 50 Mbytes/sec. If the traffic is significantly below this, it is not the fault of the physical USB2, but rather those processes using the USB interface.

I have a Windows 2012R2 headless server here with 4 x 4TB drives (SATA) and 4 x 3TB drives (SAS - cheap as chips on e-bay). Drives are on a Dell PERC H700 (needs a small physical mod to work in non-Dell machines) with battery backup.
This server is fast and (apparently) highly reliable, the only failure I have had was one of the WD Red SATA drives that crapped out after about 1 year - the MegaRaid software sent me an alert and I did a cold-swap and it rebuilt nicely. The s/h SAS drives seem to be bullet-proof (they should be, they are enterprise quality IBM/Seagate).
This is my first line of defense: All our important files are stored directly to the server plus all our media files (having a fast server is great when you are copying 50GB at a time). My workstations do a Macrium GFS backup to this server. There is also a NextCloud VM which shares folders and workspace with other (remote) family members.
Additional to this server I have 2x4TB NAS (Netgear) which does a 'pull' backup of data from 3 workstations (documents, mail folder etc.) plus backups of the really important folders on the Windows 2012 server including 350GB of photos). This data is mirrored to Amazon Cloud Drive via a Netgear plug-in.
The Windows server also host a few VMs, mainly old Windows builds and temporary Linux projects.
The NAS is also used for backups of various Linux and Android devices via NFS shares.
Overkill? Maybe, maybe not - but life would be a lot more complicated without the server.
So old that I did my first coding in octal via switches on a DEC PDP 8
