al drive. Note: You will need space on your power strip or electrical outlet to plug in the power adapter.

If you are using this drive with the Xbox One and use a lot of accessories that also need USB ports, you may want to buy a 4-port USB hub. I wasn't thinking about that when I bought this and had to pick one up later.

如果您在Xbox One上使用此驱动器并使用大量也需要USB端口的配件，则可能需要购买4端口USB集线器。 当我买这个东西的时候，我并没有考虑这个问题，所以之后不得不再买一个。

have incrementally improved across generations. This model features a new case design which most notably replaced the rounded case that has been the norm since the original models years ago. The new case isn't attractive for me but it should have little effect on use.

BOTTOM LINE (for the impatient):
The new model is a little bit faster than the last one I got a couple of years ago. It's faster than a similar My Passport drive, perhaps an advantage with the physically larger drive. This model (I got the 6TB size) is available in sizes up to 8TB. A pretty massive amount of storage on a USB drive! This drive shines with sequential reads and writes using Crystal DiskMark.

This My Book has a new design that replaces rounded corners with pointy ones and adds some odd (to me) styling to the case. The new case shows fingerprints and scratches much more than the old. It's a purely aesthetic change.

If these differences are not important for you or you prefer the old model's aesthetics, you may want to shop for the older model My Book.

If you want more details, read on...

SUMMARY:
The My Book USB 3.0 drives are simple to use and come with reasonable software tools and backup/sync software. The drive includes: WD Backup, WD Security and WD Drive Utilities. I have my own backup solution and have not explored this software. If these are of interest, be sure to check for newer versions on the WD web site.

Pluses:
+ This drive works fine with Windows, Linux or Mac out of the box. With Linux or Mac it performs best when reformatted with a native file system for the respective operating system.
+ This generation has 8TB, 6TB, 4TB and 3TB single drive models. Dual drive 12TB and 16TB models are available too.
+ This drive is faster than the last generation I used. Just noticeable in practical use.
+ The form factor of the new drive is almost exactly the same as before except for pointy corners.
+ It comes with a 4ft USB 3.0 cable (much nicer than the very short My Passport cables!)

Minuses:
- A power adapter is required. Happily it has a 6ft cord which is thoughtfully long.
- The redesign of the drive case is not a plus for me. Not much of a minus either as it's not why I selected this drive. The worst thing is going with pointy corners. From a handling perspective rounded corners are nicer.
- The warranty has been reduced from 3 years for last year's model to 2 years for this one.

IN THE BOX:
The My Book comes in a easy to open retail package containing the drive, power adapter and USB 3.0 cable. There are a couple small pieces of paper for warranty and quick-start. That's it.

TESTING:
I tested My Book 6TB model using CrystalDiskMark benchmark software and by copying 11GB folder of updates and files to the drive. This was to compare the benchmark with real-world copying. The 11GB folder has a broad mix of file sizes and types including files an over 2GB iso DVD images.

For my testing the My Book drive was connected to the Renasas USB 3.0 chip set on my Dell Precision E6500 laptop. I have the latest Renasas drivers installed. The laptop also has a Samsung EVO SSD as the hard drive (matters for my real-world copy testing).

CRYSTALDISKMARK Results:
Sequential Read (Q= 32,T= 1) : 173.515 MB/s
Sequential Write (Q= 32,T= 1) : 172.732 MB/s
Random Read 4KiB (Q= 32,T= 1) : 0.666 MB/s [ 162.6 IOPS]
Random Write 4KiB (Q= 32,T= 1) : 2.334 MB/s [ 569.8 IOPS]
Sequential Read (T= 1) : 172.583 MB/s
Sequential Write (T= 1) : 168.193 MB/s
Random Read 4KiB (Q= 1,T= 1) : 0.595 MB/s [ 145.3 IOPS]
Random Write 4KiB (Q= 1,T= 1) : 2.272 MB/s [ 554.7 IOPS]
Test : 1024 MiB [F: 0.0% (0.2/5589.0 GiB)] (x9) [Interval=5 sec]

REAL WORLD COPY:
In my real world copy test the new My Book drive was noticeably faster than the older My Book. More on the writing than reading side. It peaked out at about 300MB/s with large files. It never dropped below 180MB/s even with large amounts of small files being copied to the drive.

The newer drive may have a larger on-drive write cache or maybe it's just a bit faster drive. Maybe both. With big copies the new My Book may save you a few seconds here or there, but it's an evolution across models with each new one performing a little better.

CONCLUSIONS:
The My Book line of drives from Western Digital has been very good over the years to me and to my clients. This reliable and good to excellent performing line has a long positive history with me.

This WD My Book model is an evolution over the older models I've used. I'll pick it for new purchases over the older model, but won't rush out to replace older drives. The new case design is not aesthetically pleasing to me . Overall it's a excellent successor to a 5 star predecessor and continues to be a very good external storage choice.

For making improvements that outweigh a small misstep in case design and not making a mess of something that has been working well for a long time This new generation of My Book drives is worth 5 stars in my opinion.

Hope this helps someone!

UPDATE: 22-Oct-2017:
It's been a year+ since I got my drive and it is still working reliably for me as a backup medium for all my media files (music, video, photos). So far so good. I still have not warmed up to the case design, but didn't select this drive on its looks! This remains a 5 star drive in my use.

My Book硬盘已经被证明是可靠且质量很好的产品。他们已经逐渐改善。这款产品采用了全新的表壳设计，最显着的就是取代了原来的几年前的标准。新的款式对我来说并不吸引，但它对使用应该没有什么影响。

底线（不耐烦的地方）：

这个新模型比我几年前得到的最后一个模型速度要快一点。它比类似的My Passport驱动器更快，或许是体积更大的驱动器的优势。这个模型（我得到了6TB大小）可用的尺寸高达8TB。 USB驱动器上有大量存储空间！该驱动器采用Crystal DiskMark进行顺序读写。

这个My Book有一个新的设计，用尖锐的圆角代替圆角，并增加了一些奇怪的（对我来说）造型。新案例显示的指纹和划痕比旧的多得多。这纯粹是一种美学上的改变。

如果这些差异对您不重要，或者您更喜欢旧款的美学设计，您可能需要购买旧款My Book。

概要：

My Book USB 3.0硬盘易于使用，并配有合理的软件工具和备份/同步软件。该驱动器包括：WD备份，WD Security和WD Drive Utilities。我有我自己的备份解决方案，并没有深度研究这个软件。如果感兴趣，请务必查看WD网站上的更新版本。

加号：

+此驱动器适用于Windows，Linux或Mac开箱即用。使用Linux或Mac时，如果使用各自操作系统的本机文件系统进行重新格式化，则性能会更好。

+这一代有8TB，6TB，4TB和3TB单驱动器型号。双驱动12TB和16TB型号也可用。

+这个驱动器比我使用的上一代更快。在实际使用中很明显。

+除了尖角外，新驱动器的外形几乎与以前完全相同。

+它配备了4英尺长的USB 3.0电缆（比My Passport短电缆要好得多！）

劣势：

- 需要电源适配器。令人高兴的是它有一条长达6英尺的绳子。

- 驱动器箱的重新设计对我来说不是一个好的选择。没有太多的减号，因为它不是我选择这个驱动器的原因。最糟糕的事情是尖尖的棱角。从处理角度来看，圆角更好。

- 保修期从去年的3年减少到2年。

在盒子里：

My Book附带易于打开的零售包装，包含驱动器，电源适配器和USB 3.0电缆。有几张小纸片用于保修和快速启动。而已。

测试：

我使用CrystalDiskMark基准软件测试了My Book 6TB型号，并将11GB文件夹的更新和文件复制到驱动器。这是为了比较基准和现实世界的复制。 11GB文件夹具有多种文件大小和类型，包括超过2GB的iso DVD映像文件。

对于我的测试，My Book驱动器连接到戴尔Precision E6500笔记本电脑上的Renasas USB 3.0芯片组。我安装了最新的Renasas驱动程序。该笔记本电脑还有一个三星EVO固态硬盘作为硬盘驱动器（重要的是我的现实世界的复制测试）。

CRYSTALDISKMARK结果：

顺序读取（Q = 32，T = 1）：173.515MB / s

顺序写入（Q = 32，T = 1）：172.732MB / s

随机读取4KiB（Q = 32，T = 1）：0.666MB / s [162.6IOPS]

随机写4KiB（Q = 32，T = 1）：2.334MB / s [569.8IOPS]

顺序读取（T = 1）：172.583MB / s

顺序写入（T = 1）：168.193MB / s

随机读4KiB（Q = 1，T = 1）：0.595MB / s [145.3IOPS]

随机写4KiB（Q = 1，T = 1）：2.272MB / s [554.7IOPS]

测试：1024 MiB [F：0.0％（0.2 / 5589.0 GiB）]（x9）[间隔= 5秒]

另外的版本：

在我的真实世界复制测试中，新的My Book驱动器明显比旧版My Book快。更多的是写入而不是读入。大文件的速度达到了300MB / s。即使将大量小文件复制到驱动器，它也不会低于180MB / s。

较新的驱动器可能具有更大的驱动器写入缓存或者可能只是更快的驱动器。也许都是。有了大量的副本，新的My Book可以在这里或那里节省几秒钟，但是这是一个跨越模型的演变，每个新模型都表现得更好一些。

结论：

使用西数公司的My Book系列驱动器多年，我和我的客户都非常满意。这种可靠的，质量良好的产品对我来说有着很久的很积极的影响。

这款WD My Book机型是我用过的旧机型的改进版本。 我会选择它来购买旧款车型的新款，但不会急于替换旧款车型。 新的外壳设计在我看来并不美观。 总体而言，它是5星级前辈的优秀接班人，并且仍然是非常好的外部存储选择。

在设计案例中做出超过小小失误的改进，并且不会弄乱长期以来运行良好的东西。在我看来，新一代My Book硬盘的价值为5颗星。

希望这可以帮助别人！

更新：2017年10月22日：

距离我的驱动器已经有一年多的时间了，它对我来说仍然可以很可靠地工作，作为我所有媒体文件（音乐，视频，照片）的备份媒体。 到现在为止还挺好。 我还没有预热到案例设计，但没有选择这个驱动器的外观！ 这仍然是我使用的5星级驱动器。

sic files 3MB to 60mb plus some videos. I did not time it or watch it closely. You can easily play movies or music from this drive without skipping.

HEAT: the drive did NOT get hot. Not even very warm while chugging away for almost a whole day relentlessly copying over 5 TB of data. The drive has vents on the 2 ends. You are supposed to put the vent side up, so the heat can exit. That means the drive will be standing on end, which is probably not how you were going to place it. There are rubber feet on the other end. I suspect that the people who said this drive runs hot did not stand the drive up as intended. You can not stack these drives, but you could stand several next to each other.

ENCRYPTION: There is NONE. That is GREAT news. I had heard that the drive was married to the case by hardware encryption. Without getting in to the reasons why that is a terrible idea, I'll just say that we don't have to talk about encryption here, because there is isn't any and that is fine. Before doing anything else, we reformatted as HFS+ for Mac, then copied over 5 TB of data.

I can tell you that if you remove the drive from the plastic case and pop it into a SATA "toaster" or other external sata case it works. The data is still there and useful. Yay! There are a lot of reviews saying that the drive will not work if removed from the case (unless reformatted), but I'm telling you it does work & all data is preserved. Maybe they did not reformat before starting a or maybe they have the dual-drive raid version. This means that if the case ever fails, you CAN put the drive into a different case & run with it as is. Great news!

NOISE: there is some vibration when the drive is running. A very low hum. It may or may not bother you There is no fan. The case has rubber mounts & rubber feet which help dampen the vibration. There is some minor vibration while running in the factory case, and also when running in a NewerTech "toaster". Neither vibrations are objectionable unless maybe you are in a recording studio.

CONNECTOR: USB 3 micro B. Just one.

POWER ADAPTER: is rated at 12v dc 1.5 A. Does not block multiple outlets in use, but it does protrude to the side. There may be a ferrite bead around the cord, near the end.

WHATS INSIDE THE PACKAGE: The drive, a warranty statement, USB to USB 3 micro b cable and power cable. Some packaging and a Need Help? card directing you to support.wd.com/contact No software is included, unless it was on the drive, which came formatted as ExFAT, but we reformatted it to HFS+ which is normal for Mac.

NO ACTIVITY LIGHT: I can hardly believe WD cheaped out by not providing an activity light. Weird, I wish it had one, but for the price/performance I'm not going to change my rating.

NO POWER SWITCH. No big deal. There is a wall-wart which isn't that bad. Does not hog more than 1 power outlet.

WHAT"S INSIDE the case: a single 8 TB WD drive (128MB cache) and a small triangular SATA to USB 3 board. (opening the plastic case is tricky! See how to on youtube & make sure you are looking at late 2016 or after. the case tabs are U shaped, pointing back at you. Very unusual & you are certain to break some tabs off. There are 3 tabs on one side, and 2 tabs on the other side of the same end. The feet end does not have actual tabs. Several credit cards, then Torx 10 and Phillips 2). Drive has a large white sticker. Model WD80EZZX. Rated at 5V 440mA, 12V 550mA DC. No jumper pins and no place for them. The bare drive feels pretty heavy compared to lower capacity drives. No software was included unless it was on the disk, which we ignored and reformatted for Mac.

All in all, I'm happy with this drive so far. At current price it is a real value and seems faster than a 'back up drive'. I'll update this review if my opinion changes, but this 8TB single drive is a Buy.

速度：驱动器用起来比我预期的要快。大约需要1天的时间通过USB3复制5.14 TB。这些大部分是音乐文件3MB到60MB以及一些视频。我没有计时或仔细观察。您可以轻松播放该驱动器中的电影或音乐，而不会跳过。

HEAT：驱动器没有变热。几乎一整天都散热很好，却很好地复制了超过5TB的数据。驱动器的两端有通风口。你应该把散热面朝上，所以热量可以散出来。这意味着驱动器将站在尾声，这可能不是你将如何放置它。另一端有橡胶脚。我怀疑那个说这个驱动器热的人没有按预期的方向放置。您无法堆叠这些驱动器，但您可以选择几个相邻的位置。

加密：没有。这是很好的消息。我听说硬盘加密与驱动器结合了。没有深入了解这是一个糟糕的想法的原因，我只是说我们不必在此讨论加密问题，因为没有任何这方面的问题。在做其他事情之前，我们将其重新格式化为Mac的HFS +，然后复制超过5TB的数据。

我可以告诉你，如果你从包装中取出驱动器并将其放入SATA“烤面包机”或其他外部SATA驱动器的情况下工作。数据仍然存在并且非常有用。好极了！有很多评论说，如果从驱动器中移除驱动器，驱动器将无法工作（除非重新格式化），但我告诉你它确实有效并且所有数据都被保留。也许他们在开始之前没有重新格式化，或者他们可能拥有双驱动RAID版本。这意味着，如果案例失败，您可以将硬盘放入不同的机箱并按原样运行。好消息！

噪音：变频器运转时有振动。非常低的嗡嗡声。它可能会或可能不会打扰你，没有散热的风扇。案件有橡胶登上＆橡胶脚，帮助减少振动。在工厂情况下运行时会出现一些小振动，并且也会在NewerTech“烤面包机”中运行。除非你是在录音棚里，否则振动都不会令人反感。

连接器：USB 3 micro B.只有一个。

电源适配器：额定电压为12v dc 1.5 A.不会阻塞多个使用中的插座，但它确实会突出到侧面。线的周围可能有铁氧体磁珠，靠近末端。

包装内含：驱动器，保修声明，USB至USB 3微型b电缆和电源线。一些包装和需要帮助？卡将您指向support.wd.com/contact除非包含在驱动器中，否则不包含软件，该驱动器被格式化为ExFAT，但我们已将其重新格式化为HFS +，这对于Mac来说是正常的。

没有闪动的灯光：我几乎不相信WD没有提供闪动的灯光。奇怪，我希望它有一个，但对于性价比我不会改变我的评价。

无电源开关。没什么大不了。没那么糟糕。不过不要超过1个电源插座。

案例分析：一个8 TB的WD硬盘（128MB缓存）和一个小型的三角形SATA转USB 3板（打开塑料外壳非常棘手！看看如何在YouTube上观看，并确保您是在2016年年底或之后看，表壳标签为U形，向后指向你，非常的不寻常，你肯定会将一些标签折断，一侧有3个标签，同一端有另外两个标签。没有实际的选项卡，几个信用卡，然后是Torx 10和Phillips 2）驱动器有一个大的白色标签WD80EZZX型，额定电压为5V 440mA，12V 550mA DC，没有跳线引脚，也没有放置位置。与较低容量的驱动器相比，这是一个沉重的问题。除非它在磁盘上，否则我们忽略并重新格式化为Mac。

总而言之，迄今为止，我对这个驱动器感到满意。以目前的价格来看，这是一个真正的价值，并且似乎比“备份驱动”更快。如果我的意见发生变化，我会更新此评论，但此8TB单驱动器是值得购买的。

nsurance.

the same room as this hard drive while it backs up. The only bright side is that the noise from the pool pump running right outside my window no longer bothers me because I can’t hear it over my WD 8TB HDD.
