What is the most important thing about the NAS disk, stability!For both small and medium-sized businesses and home studios, NAS can be said to be the last barrier to data security. Once there is a problem with the NAS disk, it is a big loss for the company and the studio!As a person with more than 10 years of experience in using NAS, I combined with the recently purchased Western Digital Red Disk Plus, **Let's take a look at the purchase principle of NAS disk!
1. Why would I choose Western Digital Red Disk Plus!
Optimized for NAS use, StableTrac makes it more stable.
Powered by CMR vertical technology, it is fast and long-lasting, allowing NAS to work all year round.
Exclusive NASWARE(TM) 30, resulting in a 35% improvement over standard hard drives.
It has a RAID error recovery control function to reduce failures in the NAS system.
With MTBF of 1 million hours and a workload of 180T years, WD Red Drive Plus is specially customized for families and small and medium-sized enterprises. Stable enough, safe enough and fast enough to meet the needs of audio processing and productivity software centralized calling. This is also what I have actually felt after using it for a long time. Therefore, this time the capacity increase is selected to 8TB Western Digital Red Drive Plus.
Second, the rare opportunity to show your face must be given!
As a piece of red disk PLUS that has been "lurking" in the NAS for a long time and is immersed in data work, it is still very good-looking. It is boxy, and on the front is the label of the red plate. In the Western Digital series, red stands for NAS only. 
As a piece of 35-inch big guys, it is estimated that friends who don't play NAS rarely meet. When you hold it in your hand, you will immediately feel its weight. 
On the back of it is a green PCB board with SATA3 on it0 data and power supply interfaces. The overall workmanship is still good. 
In addition, we can also know from the data on the official flag that it is 8TB, which is 5640rpm, and has CMR and NASWARE 3With the support of 0 technology, the workload is 180TB years, and it provides 3 years of service that is only replaced but not repaired.
3. Speed test before putting in the NAS
We also tested it speed with a hard drive enclosure before putting it into the NAS. 
The above is the hardware information of Western Digital Red Disk Plus, interested partners can take a look. 
In addition, we tested it using CrystalDiskmark, where it has a read speed of 22118mb s with a write speed of 21566mb/s。
We also tested it again using ATTO. Through the test, you can intuitively see that the reading speed of Western Digital Red Disk Plus for files of different sizes. As we can see from the figure above, files of 64KB and above have maintained reads and writes close to the peak, which is quite good.
We also tested it with HD Tune Pro, and the full disk read speed curve was pretty much as expected. Among them, the speed from the outer ring to the inner ring is basically stable at 200mb s 952MB s, which can fully meet the use environment of most local area networks.
Fourth, the installation and experience of Western Digital Red Disk Plus
The Western Digital Red Drive Plus uses standard interfaces and screw positions, so it is almost impossible to get started when installing. This time, we are using QNAP from a long-established NAS manufacturer.
It should be noted that the performance of hard disks in NAS is limited by the speed of routing and transmission networks in addition to the performance of NAS devices. At present, the LAN of my studio is still in the gigabit network. We also tested the actual copy speed from the NAS, and it was pretty good to be able to stabilize above 100MB s.
Whether we call up the movie in any NAS, or **or** material, it can achieve stable and fast transfer. In other words, with the existence of such a hard disk, it has basically played to the extreme speed of my local area network. Of course, if your whole family is 25G network, there will be a greater speed increase.
In addition, we have tested the noise and temperature of its use. Among them, under high loads, it has a noise value of 376 decibels. (Since the hard disk enclosure does not have noise and shock reduction measures, it is tested with a screen cloth, which is also closer to the actual performance). When the hard disk is running, it can ensure that the office environment is quiet and will not affect everyone's work.
In the process of heavy use, we can also see that its maximum temperature is 31, and the overall feeling is also good. It can fully meet the requirements of year-round and relatively closed NAS environment.
Summary:Generally speaking, as an 8TB capacity NAS special disk, although the Western Digital Red Disk PLUS is a bit expensive, it has excellent performance in terms of stability and read and write speed thanks to the blessing of a number of technologies. At the same time, the lower operating noise also allows us to obtain a relatively quiet environment when using it. If you want to add a NAS disk for your home studio or business, then this red disk PLUS from the "time-honored" Western Digital is very worthy of your consideration!
