The SanDisk Professional G-Drive is a fantastic option for creative professionals who handle large media files such as movies, RAW and edited photos to expand the storage capacity of your existing laptop or desktop.

SanDisk Professional G-Drive是处理电影、RAW和编辑照片等大型媒体文件的创意专业人士的绝佳选择，可扩展现有笔记本电脑或台式机的存储容量。

The SanDisk Professional G-Drive is a well-engineered conventional HDD with excellent build quality. We love that it is stackable and mountable to suit your individual workstation. There aren't any software facilities, but in our experience, many portable hard drive users often don't utilize this anyway.

SanDisk Professional G-Drive是一款精心设计的传统硬盘，具有出色的构建质量。我们喜欢它是堆叠和安装，以适应您的个人工作站。没有任何软件设施，但根据我们的经验，许多便携式硬盘驱动器用户通常不会利用这一点。

As with the FireCuda Gaming Hub, the G-drive (both being Desktop Drives) is relatively slow compared to a typical SSD drive and could be considered as one of the more expensive ways to expand your storage. Though this hard drive comes pre-formatted for Mac, it can easily be reformatted for Windows.

与FireCuda Gaming Hub一样，与典型的SSD驱动器相比，G驱动器（都是桌面驱动器）相对较慢，可以被视为扩展存储的更昂贵的方式之一。虽然这个硬盘驱动器是为Mac预先格式化的，但它可以很容易地为Windows重新格式化。

The Samsung Portable SSD T7 is an extremely lightweight, pocketable external SSD. It offers fast transfer speeds and, thanks to its aluminum unibody construction, a durable shock-resistant design. It comes preformatted in the exFAT file format so it will work with Windows, macOS and Android straight out of the box, without the need for reformatting.

三星便携式SSD T7是一款非常轻巧的便携式外置SSD。它提供了快速的传输速度，并由于其铝一体式结构，耐用的抗震设计。它以exFAT文件格式预先格式化，因此它将直接与Windows，macOS和Android一起使用，而无需重新格式化。

As with all SSDs, it is built with no moving parts, so it's less susceptible to data loss than traditional hard drives, and you are afforded extra peace of mind with the three-year limited warranty. It is drop-resistant at up to 6.5 feet but lacks a formal IP rating, so it hasn't been tested for water or dust ingress.

与所有SSD一样，它没有移动部件，因此它比传统硬盘更不易丢失数据，并且三年有限保修让您更加安心。它在高达6.5英尺的高度具有防摔性，但缺乏正式的IP等级，因此没有进行过水或灰尘进入测试。

Your data is password-protected with AES 256-bit hardware encryption — you just need to use a strong password. There is a 'touch' version of this hard drive that offers biometric (fingerprint) security if that's something you'd benefit from.

With the sheer amount of external hard drives available, purchasing can be overwhelming. We've summarized our advice to help you find the best device.

随着大量的外部硬盘驱动器可用，购买可以压倒性的。我们总结了我们的建议，以帮助您找到最好的设备。

Two of the most popular types of external hard drives — Hard Disk Drive (HDD) and Solid State Drives (SSD)

两种最流行的外部硬盘驱动器类型-硬盘驱动器（HDD）和固态硬盘（SSD）

HDDs are relatively inexpensive and can accommodate significant data volumes. If you have huge amounts of data to store and you won't be moving it around too often, this is an affordable way of extending your storage. HDDs store and retrieve data using magnetic storage with one or more rigid rapidly rotating platters coated with magnetic material. Because of the moving components, they can be more susceptible to breakages if they are bumped or knocked — they generally aren't considered as robust as an SSD.

HDD相对便宜，可以容纳大量数据。如果你有大量的数据要存储，你不会经常移动它，这是一个经济实惠的方式来扩展你的存储。HDD使用具有一个或多个涂覆有磁性材料的刚性快速旋转盘片的磁性存储来存储和检索数据。由于移动组件，如果它们被碰撞或敲击，它们可能更容易损坏-它们通常不被认为像SSD那样坚固。

Solid-state drives (SSDs) represent a newer generation of external hard drives utilizing flash memory for data storage. They typically surpass HDDs in speed and durability, offering a more resilient and responsive storage solution. However, for these reasons, they come with a higher price tag and more limited storage capacity than HDDs.

固态硬盘（SSD）代表了利用闪存存储数据的新一代外置硬盘。它们通常在速度和耐用性方面超过HDD，提供更具弹性和响应性的存储解决方案。然而，由于这些原因，它们的价格更高，存储容量比HDD更有限。

Remember, regardless of which external hard drive you choose, store your data in numerous places and back it up regularly. This is good practice so you don't lose your precious data.

请记住，无论您选择哪种外部硬盘驱动器，都要将数据存储在多个位置并定期备份。这是一个很好的做法，这样你就不会丢失宝贵的数据。

Most of the hard drive models on this list are available with different storage capacities. Obviously, the more data you have to store, the higher capacity you will need. HDDs tend to be cheaper per gigabyte. The highest capacity model featured in this guide is the SanDisk Professional G-Drive, which has a ridiculous 22TB of storage.

此列表中的大多数硬盘型号都具有不同的存储容量。显然，您必须存储的数据越多，您需要的容量就越大。硬盘每千兆字节往往更便宜。本指南中最高容量的型号是SanDisk Professional G-Drive，它拥有荒谬的22 TB存储空间。

Some external hard drives require an external power source, and some don't — you'll need to consider this if you're looking for a highly portable storage solution. Using a hard drive that doesn't require it's own power supply requires less planning and offers more flexibility, but if you're just looking for a means to extend your home's computer storage and are happy for it to stay where it is, plugged in, this doesn't matter.

有些外置硬盘需要外部电源，有些则不需要-如果您正在寻找高度便携的存储解决方案，则需要考虑这一点。使用不需要自己电源的硬盘驱动器需要更少的规划，并提供更大的灵活性，但如果您只是在寻找一种扩展家庭计算机存储的方法，并且很高兴它留在原地，插上电源，这并不重要。

Most of the hard drives we've featured in this guide will either connect to your laptop/computer/tablet with a USB-C or USB-A cable, that will be supplied with the hard drive. There are a couple of Micro-USB (or other connection) models that you may want to steer clear of if you don't want to carry multiple cables, read the specs descriptions above to find out what each device uses.

我们在本指南中介绍的大多数硬盘驱动器都将通过USB-C或USB-A电缆连接到您的笔记本电脑/电脑/平板电脑，该电缆将与硬盘驱动器一起提供。有几个Micro-USB（或其他连接）模型，如果你不想携带多根电缆，你可能想避开，阅读上面的规格描述，以了解每个设备使用什么。

Each device's speed will be listed above as 'RPM' for HDDs and megabytes per second (MB/s) for SSDs. RPM is the number of rotations per minute of the spinning platters; the higher the RPM, the faster you can transfer and access your data. Similarly with the SSDs, the higher the MB/s, the quicker the data transfer speeds.

每个设备的速度将在上面列出，对于HDDs为“RPM”，对于SSD为每秒兆字节（MB/s）。RPM是旋转盘片每分钟的转数; RPM越高，您传输和访问数据的速度就越快。与SSD类似，MB/s越高，数据传输速度越快。
