The difference between the colors or types of hard disk (Western Digital) Western Digital or WD
-----------------------------------
1- Green hard disk WD Green HDD
This type is designed to be environmentally friendly and have the least energy consumption, where its energy saving reaches 40%, it also has silent operation and very light or semi-dumb noise, and it allows for large spaces and sizes with a suitable price, you can afford its costs either for RPM or the number of cycles in The minute Rotation Per Minute ranges from 5400 to 5900 and the disk also supports technologies such as PMR vertical data recording technology and IntelliPower technology for energy management. These hardships are available only with Sata type connectors. It is worth mentioning that Western Digital has integrated the green hardware into the hard types. Blue, therefore, you can say that the green hard has become the blue hard now, and it is preferred to be used only in storage and it is preferable to be used as the primary hard (not putting Windows OS on it) in the device due to its less efficiency.
-----------------------------------------------
2- WD-Blue-HDD hard disk
This is the type suitable for the use of most computer users, where it has Sata and IDE interfaces, and it allows sizes from 250 GB and up to 6 TB with RPM rolls ranging from 5400 to 7200 and a cache up to 16, 32, and 64 MB. This hard drive comes with many technologies that made it great and suitable for normal use, one of those are IntelliSeek to save energy by controlling the mechanics of the engines, No Touch technology that prevents the reading heads from touching the platters inside the hard drive itself and ShockGuard technology that protects the hard drive as much as possible from shocks. In addition to the technology of silent operation, which is not accompanied by high noise, it is also one of the excellent types in the Booting take-off process, this type of hardware is suitable for use as the core hardware of the device where the operating system and software are loaded, and is suitable for personal users' devices.
------
There is also a type of SSHD, and it is another type of blue hard.
Inside the blue hard, we will find another type, which is Blue SSHD, which is an abbreviation for (Solid State Hybrid Drive), which combines the large sizes, not the types of Western Digital, Western Digital with NAND flash SSD technology, and thus integrates speed and large sizes, and works on NoteBook notebooks of 1 terabyte and a computer. Regular Desktop with the size of 4 terabytes, and it is worth mentioning that Sata cables for both types either regular Blue HDD or SSHD support data transfer speed of 6 GB per second.
---------------------------------
WD-Black-HDD-Hard Disk 3-
It is the fastest and most capable hard but it is also the most expensive among the different types, and this type provides great compatibility between the category of gaming computer users and the professional user, as well as the normal user, but it consumes very much power, this type has a range of 1 Tera to 6 Tera, and the black hard is supported The cache is from 64 MB to 128 MB, which increases the overall performance of the hardboard, and reduces the time of reading and writing processes on the hardboard. For the standard RPM of this type is 7200, the most important thing that distinguishes this type is the use of many great technologies, and perhaps the most important is Dual Processor, which is used to double the speed. Processing orders, processes, and StableTrac technology that works to reduce vibrations, and this type is also one of the great types in Booting take-off.
-------------------------------------------
4- Red Hard Disk - WD Red HDD
This type is designed to serve (network storage) and work in servers, where it can work for 24 hours a day, 7 days a week, and comes with a warranty of up to 5 years, as it is designed for continuous operation and low energy consumption with low temperature, and this type also supports Sata cables. The size of this type of hardships is between 750 GB and 8 TB in some hardships.
-------------------------------
5- WD Purple HDD Hard Disk
This hard is designed for working in continuous recording, monitoring and working for a long period of time, and it works with Allframe technology, which reduces the frequent interruptions of video recordings and others, so it is recommended to use it with continuous recording, this type is available in sizes between 500 GB and up to 8 GB and a maximum number of 32 cameras recording there Another model called The Purple NV can support more than 32 cameras but has a limited size between 4 to 6TB and for both models, it has a warranty of up to 3 years.
