The built-in 2GB of DDR3L RAM, which may be expanded up to 8GB, and the 512MB of flash memory allow quick access to frequently-used files and programs. Network connectivity is achieved via the 2 x Gigabit Ethernet ports. A variety of RAID modes are also supported, including RAID 0,1, 5, 5 + hot spare, 6, 10, which offer data redundancy, speed, or a combination of both. There is also the option to set the TS-451+ in single disk or JBOD mode if you don't need RAID functionality.

This 4-bay enclosure has the ability to natively house both 3.5" or 2.5" SATA III & SATA II hard drives or SSD drives. To support both drive formats, screws are included to accommodate both drive sizes. Read speeds can reach up to 225 MB/s and write speeds can reach up to 224 MB/s, while data transfer speeds with AES 256-bit encryption can reach read speeds of up to 204 MB/s and write speeds of up to 158 MB/s.

question

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.
I bought the Qnap TS-451+ for just such a reason. It might be a fit for you, but look into other models that might better fit your needs.

question

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.

question

Hey guys, So is it worth the upgrade to 16gb from 2?
Asked by: Joshua T.
So Joshua, If you question is, is it worth upgrading from a single 2 TB external drive to a 4 bay NAS that can hold anywhere from 8 TB to say 32 TB, that would all depend on what your needs are and what you want to accomplish. I am a photographer, am running a raid 5 because I want redundant back up where I can hot swap out a drive should one fail and not loose all my clients imagery.
