So I have just finished building and setting up my home NAS(16TB, 8TB effective due to redundancy, Raid 10), which is for file security and easy access from multiple computers in the house, and the network is running on a Gigabit network, and large files peak at 112MB/ps which sounds spot on to me.
The problem is it still feels a bit slow, especially for Terabyte level transfers.
I am assuming this is the best I am going to do on a gigabit network, so my question is, what kind of cost and work would I need to dedicate to up that to 10 Gb. Would this be feasible on Cat 7 shielded(my current networking), or would I be better off looking at fiber?
are you sure the network is the problem, with a lot of NAS devices, especially the ones using mechanical drives (I assume you have those, because 16 TB SSD will cost a fortune), you will hit the hard drive's data transfer limit before you hit the gigabit network limit.
what kind of hard drives are in the nas?
It is my own, nothing prebuilt, as this is not the way I do things
And more than anything, I am asking about possible solution paths and the kind of expense I would be looking at as well as the pitfalls I should expect by going that route.
As far as people being concerned about drives being the bottleneck, its not even close. I am currently capping out my 1gigabit network and the drives are not even running at 1/2 of their potential speed(or more if I expand later).
The drives are configured as to be delivering twice the performance of the performance of a single drive(4 in raid 10), and gigabit caps to 1000 / 8, which is 125MB/s. Speed bottlenecks in the drive itself on gigabit may be a problem when repurposing old drives, but not on modern mechanicals. My raid array, when tested locally, have a sustained write speed of 310 MB/s(10GB/s for cached reads), and perform at 112 MB/s over the network. I do know I MAY get an extra 10MB/s out of using proper nics, and possibly slightly better performance for multiple small files, but that would be ridiculous
With that said, I do a lot of moving of files which need protection from loss and access to from multiple devices in my house, so my need for a nas is obvious, and the bottleneck will only grow as time goes on, and it is already limiting my productivity, but I am content FOR NOW while I gather all the information I can until I do decide to upgrade the network. I did think ahead the last time, and is wired with Cat 7 shielded(the newest iteration when I strung it). My house is not THAT large, but I have heard stories about 10 gig on copper being unreliable, so I don't want to waste my time going that path if it will actually be a waste of my time and money.
