如果您曾经购买过西部数据硬盘驱动器(Western Digital Hard Disk Drives)( WD HDD )，您就会看到它们有不同的颜色代码可供选择。这可能会让您对必须购买哪种类型的WD HDD产生混淆。(WD HDD)不同颜色的WD HDD(WD HDDs)是为不同目的而制造的。在本文中，我们将了解不同颜色的WD HDD(WD HDDs)之间的区别。
WD 硬盘颜色对比
你很了解西部数据(Digital)。它是最好的硬盘驱动器制造商之一。WD 硬盘(WD HDDs)有六种颜色代码，蓝色、红色、黑色、绿色、紫色和金色。下面我们来深入了解一下WD硬盘驱动器不同颜色代码的含义。
1]WD蓝色硬盘
让我们开始讨论西部数据蓝色硬盘(Digital Blue HDD)。它是一种通用硬盘驱动器，专为基本台式机和长期使用而制造。人们可以将这些硬盘用于日常活动，例如存储不同类型的文件和休闲游戏。这些硬盘的存储容量从 250 GB 到 6 TB 不等。
WD Blue HDD(WD Blue HDDs)有两种型号，5400 RPM，最大存储容量为 6 TB，7200 RPM，最大存储容量为 2 TB。

2]WD红色硬盘
WD Red HDD专为NAS和RAID系统而设计。因此(Hence)，这些硬盘驱动器最常被小型企业使用。NAS代表网络附加存储(Network Attached Storage)。它是连接到特定网络的存储介质。在组织中使用NAS系统的目的是形成一个中心位置来存储数据。您可以将NAS视为小型企业的私有云网络。另一方面，RAID （(RAID)独立磁盘(Independent Disks)冗余阵列(Redundant Array)) 是一个允许您将数据存储在多个硬盘驱动器上的系统。所有已配置的硬盘驱动器都充当RAID系统下的单个存储系统。
如今，许多组织每天 7 天 24 小时运转，员工轮班工作。此类组织需要 24×7 全天候访问存储介质。因此(Hence)，在这种情况下，WD Blue HDD(WD Blue HDDs)无法承受，因为它们仅设计用于一般用途。WD Red专业版硬盘可提供高达 18 TB 的存储容量。
3]西部数据绿色硬盘
WD Green硬盘是为低功耗而制造的。如果用户需要硬盘进行备份存储(backup storage)，或者只是为了存储他的文件，他可以使用WD Green HDD。由于人们开始更加偏爱WD Blue硬盘，Green HDD开始失去人气。由于这个原因，西部数据(Digital)停止生产绿色硬盘(Green HDD)。

4]WD黑色硬盘
Western Digital为需要(Digital)高性能(high performance)外部存储介质的用户制造黑色HDD系列。由于(Due)高性能，WD Black硬盘深受照片编辑和高端游戏玩家的欢迎。如果我们将WD Black HDD与WD Blue HDD进行比较，前者提供 128 MB 的缓存，而后者仅提供 64 MB 的缓存。此外，所有版本的WD Black HDD均配备 720 RPM，远远优于WD Blue HDD提供的RPM. 简而言之，如果您正在寻找使用寿命更长、速度和可靠性更高的硬盘驱动器，WD Black HDD将是正确的选择。
5]WD紫色硬盘
WD Purple HDD系列专为监控系统而设计。监控系统需要可以 24×7 全天候写入数据的存储介质。除此之外，存储介质应具有可存储高清视频的大容量。WD Purple HDD完全符合这些要求。您可能在这里有一个疑问，“ WD Red HDD系列还提供 24×7 数据存储设施，那么，为什么这些硬盘不能用于CCTV监控系统？” 这是因为当有人在特定区域犯罪时，需要访问监控视频。这意味着监控系统中的硬盘更多地用于写入而不是读取数据。WD Red HDD并非如此. 由于组织使用红色(Red)硬盘，员工经常需要它们来访问数据。这意味着这些硬盘驱动器同样用于写入和读取数据。与红色(Red)硬盘一样，紫色(Purple)硬盘也可以配置用于NAS和RAID存储系统。
6]西部数据黄金硬盘
WD Gold HDD提供长期冷存储介质。因此，该系列西部数据(Digital)硬盘适用于数据中心。这些硬盘可以同时处理许多复杂的系统，并且可以与不同的服务器很好地配合使用。WD 黄金版硬盘的最大存储容量为 10 TB，并提供 7200 RPM和 128 MB 或 256 MB 缓存。黄金(Gold)硬盘也适用于 24×7 应用程序，每年可处理 550 TB 的工作负载。
让我们总结一下我们在本文中讨论的内容。
- WD Blue HDD：它是一种通用、可靠且节能的存储介质。
- WD Red HDD : 它是为NAS和RAID系统制造的。
- WD Green HDD：耗电少，与蓝色系列硬盘类似。绿色版现在不流行了。
- WD Black HDD：它是一款高性能硬盘，专为高端游戏和内容创作应用而设计。
- WD Purple HDD：监控系统存储设备。
- WD Gold HDD：它是 WD 硬盘的高级版本，专为数据中心和其他类似应用而设计。

What do different WD Hard Drive colors mean?
If yoυ have еver shopped for Western Digital Hard Disk Drives (WD HDD), you have seen that they are available in different color codes. This might create confusion in your mind about which type of WD HDD you have to buy. The different color WD HDDs are manufactured for different purposes. In this article, we will see what is the difference between the different color WD HDDs.
WD Hard Drive colors comparison
You are well aware of Western Digital. It is among the best hard disk drive manufacturers. There are six color codes for WD HDDs, blue, red, black, green, purple, and gold. Let’s have a deeper look into the meaning of different color codes of WD hard disk drives.
1] WD Blue HDD
Let’s begin our discussion with the Western Digital Blue HDD. It is a general-purpose hard drive that is manufactured for basic desktop and long-term usage. People can use these hard drives for daily activities like storing different types of files and casual gaming. The storage capacity of these hard drives varies from 250 GB to 6 TB.
WD Blue HDDs are available in two models, 5400 RPM with a maximum storage capacity of 6 TB and 7200 RPM with a maximum storage capacity of 2 TB.

2] WD Red HDD
WD Red HDD is designed for NAS and RAID systems. Hence, these hard drives are most commonly used by small businesses. NAS stands for Network Attached Storage. It is a storage media that is connected to a particular network. The purpose of using a NAS system in an organization is to form a central location to store data. You can consider NAS as a private cloud network for small businesses. On the other hand, RAID (Redundant Array of Independent Disks) is a system that lets you store the data on multiple hard drives. All the configured hard drives act as a single storage system under the RAID system.
Today, many organizations operate 24×7 with employees working in rotational shifts. Such organizations need 24×7 access to the storage media. Hence, in such circumstances, the WD Blue HDDs do not withstand as they are designed only for general purposes. The pro version of WD Red hard drive is available with a storage capacity of as high as 18 TB.
3] WD Green HDD
WD Green hard drives were manufactured for low power consumption. If a user requires a hard drive for backup storage, or simply for storing his files, he can use WD Green HDD. Because people started giving more preference to WD Blue hard drives, Green HDD started losing their popularity. Due to this reason, Western Digital stopped manufacturing the Green HDD.

4] WD Black HDD
Western Digital manufactures the black color HDD series for those who want an external storage medium with high performance. Due to the high performance, WD Black hard drives are much popular among photo editors and high-end gamers. If we compare WD Black HDD with WD Blue HDD, the former one offers 128 MB of cache, whereas, the latter one offers only 64 MB of cache. Also, all the versions of WD Black HDD come with 720 RPM which is far better than the RPM offered by WD Blue HDD. In short, if you are looking for a hard disk drive that lasts longer, offers high speed and reliability, WD Black HDD will be the right choice.
5] WD Purple HDD
WD Purple HDD series is specially designed for surveillance systems. The surveillance systems require storage media on which data can be written 24×7. Apart from this, the storage media should have a high capacity where the high definition videos can be stored. WD Purple HDD perfectly fits these requirements. You may have a question here, “WD Red HDD series also offer 24×7 data storage facility, so, why these hard drives cannot be used for CCTV surveillance systems?” This is because the surveillance videos are required to be accessed when someone commits a crime in a particular area. This means that the hard disks in surveillance systems are used more for writing than reading the data. This is not the case with WD Red HDD. Because Red hard drives are used in organizations, employees need them frequently to access the data. This means these hard drives are used equally for both writing and reading the data. Like Red hard drives, Purple hard drives can also be configured for NAS and RAID storage systems.
6] WD Gold HDD
The WD Gold HDD provides a long-term cold storage medium. Therefore, this series of Western Digital hard drives is suitable for data centers. These hard drives can handle many sophisticated systems simultaneously and work well with different servers. The gold edition of WD hard drives comes with a maximum storage capacity of 10 TB and offers 7200 RPM with 128 MB or 256 MB cache. Gold hard drives are also suitable for 24×7 applications and can handle a workload of 550 TB per year.
Let’s summarize what we have discussed in this article.
- WD Blue HDD: It is a general-purpose, reliable, and power-efficient storage medium.
- WD Red HDD: It is manufactured for NAS and RAID systems.
- WD Green HDD: It consumes less power and is similar to the blue series hard drives. The Green edition is not popular nowadays.
