Are the QNAP TS-251A and TS-451A the Direct USB Access NAS you have been waiting for?
About Connections, how do they differ?
What are the specifications of the TS-251A and TS-451A?
The specifications of both units are as follows
Supports JBOD, RAID 0, RAID 1 and RAID 5 (only on the TS-451A)
14nm Intel® Celeron® N3060 dual-core 1.6GHz processor, up to 2.48GHz (same as DS216+II)
2 or 4GB RAM (maximum of 8GB across two slots)
Kinda the key selling point – USB Direct Access. How to connect is as follow:
• Connect a USB cable to the front of the NAS (slim USB 3.0 type Micro B)
• Connect other end to your PC or Mac via a standard USB Type A port
• Connect and access your device for the first time using QFinder Pro software (free)
• NAS can still be accessed in traditional NAS way whilst USB Direct Attached accessed is used
• Password and User account control can be applied or suspended as required for protection
Lastly, both units support Native 4K and HD Transcoding – though cannot expect the same resolution support in Plex Performance in a NAS based Plex Media Server. Additionally, both units support Dual OS support, as in the X53A range. So you can utilise a QTS and Linux OS.
With regard to Read and Write speeds, through two LAN ports are 194.5MB/s Read and 211.88 MB/s Write across both the QNAP TS-251A-2G and QNAP TS-451A-2G. Also you have a Remote control included for selecting and controlling media applications via that HDMI port. Both units are Windows and Mac compatible, feature VM supported as well as QvPC with the USB and HDMI ports (by connecting a Keyboard, Mouse and HDMI monitor). Likewise, this same connecivity means you can create a standalone Surveillance Network with 2 Camera licences included and the ability to connect upto 32 more.
Price, Warranty and Where to Buy the TS-251A?
This box comes with 2 year warranty for your peace of mind and long term hardware security. The Qnap TS-451A is £91.00 cheaper than the most expensive unit TS-451A-2G.
