Both QNAP TS-251 and QNAP TS-251+ are designed quite similarly to each other. The layout and placement of buttons are identical. Fortunately, though, the company has decided to dye QNAP TS-251 in an off-white color, whereas QNAP TS-251+ is dark gray, allowing you to easily distinguish one from the other. QNAP TS-251 is available in two capacity choices, 1 GB diskless and 4 GB diskless.

QNAP TS-251 and QNAP TS-251+ is powered by different engines. QNAP TS-251 relies on a 2.41 GHz dual-core Intel CPU, which is actually pleasantly fast and reliable already. However, QNAP TS-251+ is armed with a 2.0 GHz quad-core Intel CPU. Having more cores, it is able to process more tasks at once, effectively increasing the processing speed especially at high traffic.
Besides, QNAP TS-251 is an older model while QNAP TS-251+ is a newer model. QNAP TS-251+ comes with a more sophisticated design than QNAP TS-251 that enhances its speed and performance. This is especially evident when comparing their performance with the AES 256-bit encryption activated. QNAP TS-251 experiences a significant drop in both read speed and write speed. It reads at 128 MB/s and writes at 95.7 MB/s. Meanwhile, QNAP TS-251+ doesn’t struggle as much, reading at 205 MB/s and writing at 178 MB/s. As you can see, the gap is real.
Regarding the features, both devices support similar features and functions, such as the ability to run multiple virtual machines, stream via DLNA, AirPlay, and ChromeCast, also Plex. However, QNAP TS-251 only has 3 USB ports and no HDMI port, whereas QNAP TS-251+ comes with 4 USB ports and an HDMI output. (Take a look: QNAP TS-251 Vs Synology DS216play)
