This is not a question about how long data I put on the SSD’s will last.
Counterargument, you actually ARE. For example, the firmware is also stored on flash (albeit it's NOR instead of NAND as far as I know).
I have absolutely no clue how long NOR flash lasts, although I have heard anecdotally that it is much more reliable (and more expensive) than NAND. Hence why SSDs use NAND for mass storage, and use NOR for shit like firmware.
Is there any reason they won’t work after that amount of time?
Without that firmware it's not gonna do a whole lot lol. So I don't have an answer to your question, but I feel like it should also be considered.
There will be bottlenecks?
Probably? Maybe? ¯\_(ツ)_/¯ didn't give a whole lot of information
PCIe 1x use 1gb/s
Pcie gen 3.0 x1 is 1GBps. Is both your slot AND your card gen 3 or higher? Older cards are usually gen 2
4 x 200 mb/s = 800 mb/s
Yes that is how that would work assuming the card uses gen 3... Although given the fact that you said theres 1 SAS port, I doubt its gen 3. Single port cards were mainly a thing on SAS 1/2 cards, which predominantly used PCIe gen 2.
I mean... As long as you can get it in there it'll run. Just not at full bandwidth ¯\_(ツ)_/¯
Minimum $0
Maximum $infinity
That's an HDD, much cheaper (like 5~6x) for the capacity than SSDs.
It'll work fine. As for 16 vs 20TB you most likely don't have to worry about it. Usually those "limits" exist because drives larger than 16TB didn't exist at the time, or they existed but the manufacturer didn't bother certifying.
The only actually limit for something like this is 2TB. If it says it can do more then it has no effective limit.
How... the hell are you finding 20TB SSDs for that price? 15TB ones are like $1k lol
I will probably go with the ZFS file structure
What do you mean "think"? You don't get a choice on TrueNAS lol
How good is ZFS at redundancy?
The... Exact same as other RAIDs I guess?
With the HDD's how much redundancy will I need if I want to use one as a fail-safe if the other dies?
Minimum of 1? Not entirely sure what you're asking
Also, I have heard that to install TrueNAS you need 32GB ram. However I have 16GB ddr4 3200mhz, is this enough?
More than enough. I got it running on 2.5GB ¯\_(ツ)_/¯
and the other to use as a caching drive.
Caching does not work the way most people think it works on ZFS
Also, will I be able to add more drives (easily) with ZFS at a later stage?
If you buy in sets instead of 1 drive at a time, yes. If not, YMMV
Do you know how much theyd cost? Lmao
If you just want to set the file size use one of the bitrate settings(?)
Isn't that what it does by default...?
VPN + network share...?
From the single sentence explaining what it does, absolutely not. I can choose a directory and share it within 10 minutes.
You aren't the first person to come up with this idea, nor will you be the last.
Better finance some lawyers first. What are you going to do as soon as you get a DMCA notice? Or if one of your tenants store something super illegal? Lmao
