Any performance experience with raid 5 or 10 (4 hdds) to share?
Asked by: Ariel
This has functioned very well and meets my needs perfectly. I also like that it works great with my UPS so if I have a power outage it automatically switches to the UPS for power so it can then safely power down (in my area the power can be unstable). It is a bit noisy in the bedroom overnight (not loud but not quite white noise) so I'm thinking of moving it elsewhere. A very minor drawback & not an issue if you have somewhere else to put it.

I am a video editor and I use mostly 4k raw footage. I do not have any server I only use Seagate external hard drives, but one of them just broke and I lost about 3tb of data. I am trying to get one of these servers to back up my data but also use it to edit my video out of it. Any suggestions? Thank you in advance!!!
Asked by: Luis C.
You may need a NAS that has a thunderbolt connection to be able to edit the video off of the storage. TS-451+ is a great storage slution as long as you edit your footage off of an SSD or other high speed drive.

Will this work with WD Black 7500 RPM drives?
Asked by: Larry
I would not recommend it as they are not TLER drives. Google TLER drive. They may cause frequent drop-outs and rebuilds.
