A brief explanation of a rough understanding of NAS on the market.
1. Brand.
There are many NAS brands in the domestic market. Among them, the largest user groups in China are Synology and QNAP.
The advantage is that the software is powerful and easy to use.
The shortcomings are equally obvious: price-specific and expensive. Quotes for 2K-4K.
The second brands are thecus, buffalo, NETGEAR, iconnect, D-link and other manufacturers. These brands are cost-effective. Especially buffalo and color card.
Talk about my familiar buffalo, his 4 disk machine, the licensed price is 1400 look, the big factory produced, the hardware said the past. But the software I think buffalo is the most irresponsible one of the many companies produced, from the web page To the system optimization, they are all done with perfunctory things, not in line with the definition of the big factory.
Let's talk about the Thecus, at the price of 3,000 to 5,000, the price is very high, please check the manufacturer's published parameters. Other manufacturers are not detailed, in my eyes, basically the shell and software UI Different.
2 performance
Most of the products in the price range of 1 thousand to 4 thousand are SoC, the American company Marvell. Among these brands, Qunhui and QNAP are the highest, basically the same. They have reached the maximum. The degree of optimization. Simply put, the same 1.6G frequency device, QNAP TS419P+ is more than the buffalo LS-QVL/E is 109MB / s than 75MB / s. (but the price comparison is 4500: 1400). Two key points of brand and performance The two brands, Qunhui and QNAP, are destined to be unacceptable to the general consumers. They can only be chosen by users who are not bad.
So, DDNAS V2 was born!!
