Should work. Try it. (Havent used it in a long time though...)
The other way around any limitations would be to set up a NAS and kiss sneakernet goodbye.
Good devices to set up a NAS without buying a NAS.
Zidoo X9S, or Z9S (if you can get them cheap), have the benefit of also being a Media Player/capture card/Android box. (Is a frankensteined solution that runs both Android and DD-WRT at the same time. Is great, once you've got it working - but might be tinker intensive.)
Both Zidoo boxes can also be addressed with a Harmony Universal remote (IR), in case that is important. (Best Harmony, by far is "Harmony Companion" (the cheapest one)
). But Navigation over IR will be slower than using a dedicated Bluetooth remote. (I recommend this model:

As a file manager on Android I like Total Commander btw.
(From the Paragon NTFS Play Store readme:
To work as Plugin for Total Commander file manager install it from Google Play and click the Open button on the Microsoft exFAT/NTFS for USB by Paragon Software main screen. It will open Total Commander with mounted volumes of the USB storage.
)
On any TV connected Android device my recommendation for Video playback is, and will always be - Kodi, an nothing else.
(But thats just on the player/playback side of things).
Asus RT-AC66U (Router) - which you can probably get very cheap - used. Set it up with DD-WRT, or Tomato (easier to learn), or... and it s good for 10MB/s write speeds and a little faster read speeds (will struggle with UHD content) on USB drives.
Or you go with any Synology Router, same deal - can be kept on stock firmware, far faster transfer speeds.
Or you go with a real NAS.
(Or with a WD My Book NAS (not good, but maybe good enough...
))
You have a few options, and probably even more than that - without relying on your TV.
In general - its better to just use the TV as a 'dumb device' (even if it has Smarts in it), and outsource the 'Smart' to a box. (TVs usually are abandoned by their manufacturers 1.5 years after release, and there usually also isnt much of a scene around them, that would help you maintain them)
NAS is a harddrive attached to your network, thats shared to other devices usually via smb (also via ftp) in todays ecosystem almost all connected devices with a video playback 'angle' support playback from a NAS.
Almost every 'smart' device that ist just rasp pi (usb lanes bandwidth limited) these days will also give you the benefit to allow you setting up a harddrive as NAS storage. So which one you pick - often is decided by which other capability you would want as well - and if you need UHD playback, or video transcoding (in general - today you dont need video transcoding. Every cheapo smartphone and Android TV stick can run hardware acellerated 1080p in all formats (f.e. using Kodi), presuming its not an Apple Smart(as in dumb) device. So do you want a router with it. Or a media player. Or nothing, and just pay a dedicated NAS manufacturer a 'premium' for almost nothing (dedicated NASes are faster - and something you should look at - if you are interested in 4K UHD playback. But then the Zidoo boxes do that as well (at least at 24p (hz)) - so lets say, for the most part.
If you are dealing with 4K UHD Bluray isos, go with a dedicated NAS.
Thats the basic rundown.
