In your case, there are two solutions. First, if you want to use an ordinary desktop computer to enjoy it, you can consider using windows. Server version of soft RAID, which is independent of hardware and is a dynamic disk array generated by the system, has the advantage of low cost. You can use your current computer as long as it can be installed in 2003, but the disadvantages are also obvious. Being a mirror image of the system can easily lead to errors, and then you can't enter the system, so you can only give up the system image for stability, and the stability is not as good as that of Qunhui's LINUX kernel-based NAS. Secondly, you can consider using Qunhui's NAS, and recommend DS2 12J, with dual-disk position. The performance can meet the requirements mentioned by the landlord. Moreover, the biggest advantage of using NAS lies in its friendly management interface, and novices don't have to be afraid of finding a place to set it up, because there are instructions for use. Of course, you must have a certain network foundation, but the disadvantage is the price. After all, 1800 is enough to buy one. It may stop many people, but according to the usage of our company, I can tell you responsibly that it is very stable, much more stable than WINDOWS. Although it is a soft RAID based on LINUX, it can be seen that Qunhui has done a lot of optimization, and the company has stopped power for several times, and the hard disk and machine are fine after reopening. Another advantage of this NAS is power consumption. The value of peak value 17W can basically throw away a few blocks from the desktop, and it also saves a lot of electricity bills for many years. In addition to * * * enjoyment, there are also WEB, FTP, VPN, mail service, streaming media, WIFI hotspots and firewalls. How to choose is up to the landlord, but if it is a company file, it is better to use NAS. I hope my answer will be helpful to you.
