As the world's largest hard disk drive manufacturer, Western Digital has won the favor of many enterprises and individual users with its excellent technical strength and product performance.
 
In recent years, WD, like other storage industry giants, has continued to enter storage-related industries, expand its own market blueprint, and enter the NAS industry as part of the expansion of WD's industry. Compared with traditional network equipment manufacturers, Western Digital does not have an advantage in network technology, but with years of experience in the consumer market, Western Digital has more advantages in user experience and marketing.
 
A NAS is like a small server that needs to work 24 hours a day, which is a huge test for the stability of the hard drive. Mechanical hard disk manufacturers provide network-level hard disks for NAS, which are more stable and durable than ordinary hard disks. Therefore, it is recommended that users use network-level hard disks at the same time as NAS to make data protection more reliable, after all, hardware is priceless, and data is priceless.
 
Western Digital NAS products are divided into three series according to performance from high to low: My Cloud Pro, My Cloud EX2, and My Cloud Home, the Pro series is a professional-grade NAS with 4GB of RAM as standard, and can be expanded up to 16GB by itself, but the Pro series only supports USB expansion, compared with Synology and ASUSTOR products with eSATA interface, My Cloud Pro is slightly weaker in terms of scalability. The price of the double-disk product PR2100 is 3489 yuan, and the cost performance is acceptable.
 
As a veteran hard drive manufacturer, Western Digital must also bring some "private goods" when selling NAS. The Western Digital My Cloud Pro series is available as a stand-alone NAS with or without a hard disk or as a Western Digital Red Drive package, and the warranty period for the packaged NAS is three years, while the purchase of a single NAS is only covered by a two-year warranty. If you don't have a network-level hard drive at home, it is more cost-effective to buy a bundle version.
 
My Cloud EX2 is a traditional entry-level NAS device, 1GB memory can ensure most of the daily use scenarios of the family, and the price of 1399 yuan also has a good cost performance.
 
My Cloud Home is a little different from traditional NAS, with a built-in hard drive, a small body, and simple operating logic, making it more like a networked desktop hard drive. In addition to the advantages of being small and simple, the disadvantages of My Cloud Home as a data center are also obvious: relatively weak performance, only one hard drive, insufficient data security, and so on. The 3TB version of My Cloud Home is priced at 999 yuan, which is only suitable for individual or home users who store data lightly.
