When choosing a mechanical hard disk for installation, we will find that Western Digital (WD) hard disk will have green disk/blue disk/black disk/red disk/purple disk and enterprise disk, Western Digital Company according to the characteristics of its mechanical hard disk to make a classification, and there is a color difference on the hard disk, many users don't know which hard drive is more suitable for themselves, the following installation home will explain the difference between Western Digital green disk, blue disk, black disk, red disk and purple disk and enterprise disk.
WD Green Plate, Blue Disk, Black Disk, Red Plate and Purple Plate Characteristics:
WD Green Plate
Green disk: low noise, suitable for home use, as a download disk, the advantage is lower heat generation, quieter and more environmentally friendly. energy-saving disk, suitable for large-capacity storage; With IntelliPower technology, the speed is automatically adjusted between 5400-7200. The advantages are quiet and low price; The disadvantages are poor performance, high latency, and short life.
Western Digital (WD) Blue Plate
Blue disk: suitable for home use, the advantages are strong performance, low price, high cost performance, and the speed is 7200 rpm; The disadvantage is that the sound is slightly louder than the green disk and the performance is slightly worse than the black disk.
Western Digital (WD) black plate
Black disk: high performance, large cache, fast speed. Codename: LS WD Caviar Black. It is mainly suitable for enterprises, high-throughput servers, high-performance computing applications, such as multimedia video and photo editing, and high-performance game consoles.
Western number (WD) red plate
Red disk: suitable for operating in a NAS environment, operating 24/7. Western Digital has launched a new hard drive for the NAS market aimed at home or small business NAS users with 1 to 5 hard drive bays. The performance characteristics are relatively close to that of the green disk, with lower power consumption, less noise, and the ability to adapt to long-term continuous work.
WD Purple Plate
Purple disk: The vest of AV-GP with green disk, supports streaming ignoring CRC checks, suitable for video surveillance storage, and is designed 24*7.
In addition, there are enterprise disks: the highest performance, large cache, and fast speed. Compared with desktop hard drives, the most important differences between enterprise hard drives are reliability, long-term operation, and high MTBF (Mean Time Before Failure). The speed is about the same. Enterprise hard disks are not the same as server-level hard drives, in terms of performance do not necessarily have better performance than desktop grades, for enterprise users, stability is more important, in long-term complex work, if the hard disk suddenly fails, it will bring irreparable losses to the enterprise.
Western Digital Hard Drive Summary:
Through the introduction of Western Digital mechanical hard disks above, we can see that green disks and blue disks are suitable for home computers, generally speaking, the speed of green disks is not good, most installed machines use blue disks, and black disks are usually used on servers, and red disks: between blue and green, it is purely created for NAS systems can be said to be exclusive to NAS, and purple disks are suitable for surveillance systems, supporting up to 32 high-definition cameras.
