WD ポータブルHDD 4TB USB3.0 レッド My Passport 暗号化 パスワード保護 外付けハードディスク / メーカー3年保証 WDBPKJ0040BRD-WESN 国内正規代理店品

Timemachine用（タワー型）やデータ保存用（ポータブル）、起動ディスク用（SSD）など、すべてWD（WesternDigital）製を使用しています。 Amazon以外で購入したものも含め10台近く使用してきた中で、壊れたのは２台。 タワー型の１台は風通しの悪いところに設置していたため熱にやられたようで、もう１台のポータブルは使いすぎ？なのか、PCに繋いでも認識せず、あれこれやっても初期化できず（まっさらにして使おうかと思いましたが、私の力では読み込みのみ出来る状態までにしかできませんでした）。 そろそろ追加で購入と思いきや、この値段では……。 せめて半年前の値段に戻ったら（戻らない？）、２台ほど追加購入しようと思います（昨年：2025年はAmazonで3台購入しました）。

配達日が予定より遅くなったり早くなったりバタバタでした。いまのところ普通に使えてます。WDなんで耐久性とか期待しちゃううんだけど。

ポータブルハードディスクはやはりウェスタンデジタルが1番だと思います。 日頃からハードディスク診断ソフトでチェックしていますが、非常に安定していると思います。

ノートパソコンの外付けディスクとして使ってます。 半年ほど挿しっぱなしで使ってますが。音も全く気にならず、機嫌よく動いてくれてます。

本当は星を一つもつけたくないほどに残念。Mac M1、延々にドライバがネットワークのせいでインストールできないと延々とメッセージが出ているため、調べたら、そもそも2025年7月31日に公式サポートが完全に終了しているにもかかわらず、販売されているのはなぜなのかしら・・・。やはり、日本製のものが信頼できると反省しました。

通常のバックアップであればまったく問題ありません。 大容量を短時間でバックアップする場合は、 最新のHDDよりも、転送速度が遅いです。 ２年近く、異常はありません。

WD製品なので間違いはないと思われるが、、、 今まで多数HDD使用してきた中では比較的外れは少ない。

商品については大変満足。 ただし梱包状態が極めて杜撰、およそ精密機器を配送する状態ではない。 いつものアマゾン箱の中にクシャクシャにした紙切れ1枚、梱包担当者はHDDが振動に弱いことを知っているのか？ 製品に問題は起きていないが至急改善を求める。

Needed something reliable to back up years of photos, videos, and random chaos—this 5TB WD My Passport totally delivered! Super compact and lightweight! The transfer speeds have been solid (nothing to complain about unless you're expecting SSD speeds

This model is the latest generation of the many My Passport drives I've owned or purchased for clients. They have proven reliable and good performers. They have incrementally improved with each new generation. This model features a new case design which I feel is much better looking and is slightly smaller than the last version. BOTTOM LINE (for the impatient): This model is a little bit faster than the last (2016) model I bought. I got the black 2TB model and this generation offers up to a 5TB model as well as the usual smaller capacities. This model is just noticeably faster than the last generation on sequential reads and writes when I tested using CrystalDiskMark. This My Passport has a new design that returns to rounded corners and soft-look matte case. I like this much better than the older one with its cheap-looking (to me) styling. The drive is slightly less thick, wide and long than the 2016 model. In my laptop bag that’s welcome even if not a lot smaller. I’m very pleased with this My Passport drive as with ones purchased over the last decade plus. It’s reliable, fast for a USB mechanical HD and gives a lot of space for a low price. If you want more details, read on... SUMMARY: The My Passport USB 3.0 drives are simple to use and come with reasonable software tools and backup/sync software. These are now in a single installer on the drive. I have my own backup solution and do not want encryption on this drive, so 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 (where it is read-only with NTFS). They generally performs best when reformatted with a native file system to the respective operating system. Mine came formatted with NTFS for Windows. + This generation has 5TB, 4TB, 2TB, and 1TB models. The 500GB models were dropped a couple of generations ago and more recently the 3TB models. + This drive is faster than the last generation, but just a little. Up to about 3% faster in benchmarks, but barely noticeable in practical use. + The form factor of the new drive is lighter and slightly smaller before with a much nicer case without pointy corners and scratch/fingerprint prone glossy finish. + The warranty has been returned to 3 years from 2 years on the 2016 generation. Minuses: - It comes with the same very short USB 3.0 cable as previous versions. I like a longer 3ft (or more) USB 3.0 cable : a very good upgrade purchase for the My Passport drives. IN THE BOX: The My Passport comes in a easy to open retail package containing the drive and a annoyingly short USB 3.0 cable. There are a couple small pieces of paper for warranty and quick-start. That's it. The cable in this model is the same as previous versions. This may be just fine for a lot of folks but I keep some 3ft (or more) USB 3.0 cables handy for longer runs to my desktop or even on top of a tall computer. FORM FACTOR vs. PREVIOUS GENERATION: I'll compare the new generation of My Passport with my 2016 My Passport Ultra This Model My Passport's dimensions: 1TB-2TB: 0.27lb, 4.22in X 0.44in X 2.95in 4TB-5TB: 0.46lb, 4.22in X 0.46in X 2.95in 2016 My Passport's dimensions: 1TB: 0.37lb, 4.33in X 0.64in X 3.21in 2TB-4TB: 0.54lb, 4.33in X 0.85in X 3.21in TESTING: I tested both my older 2016 My Passport 4TB drive and my new My Passport 4TB 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 image. Using CrystalDiskMark I found sequential reads were about 3% faster and writes about 8% faster with the new model. Random reads were just a tiny bit slower and writes were about 8X (!!!) faster. While the benchmarks showed significant differences using them in my real-world copy test the difference was most noticeable with lots of smallish files, but not so much with large sequential reads/writes. If you need to write smallish files this drive is noticeably better than the 2016 model and about the same for large files. For my testing the My Passport drive was connected to built-in USB 3.0 controller on my Dell 7710 Precision Mobile Workstation. I also tried it on a older add-in card with the Renasas USB 3.0 chip set on my Dell Precision T7500 tower. I have the latest Renasas drivers installed. Both are running build 1903 of Windows 10 Pro and both have SATA SSD boot drives. I used CrystalDiskMark V7 64bit version. CRYSTALDISKMARK Results: The New Generation My Passport: Sequential Read (Q8T1): 129.18 MB/s Sequential Write (Q8T1): 119.75 MB/s Sequential Read (Q1T1): 120.37 MB/s Sequential Write (Q1T1): 118.08MB/s Random Read (Q32T16): 4KiB 0.6 MB/s Random Write (Q32T16): 4KiB 10.8 MB/s Random Read (Q1T1): 4KiB 0.49 MB/s Random Write (Q1T1): 4KiB 7.8 MB/s The 2016 My Passport: The New Generation My Passport: Sequential Read (Q8T1): 125.5 MB/s Sequential Write (Q8T1): 113.7 MB/s Sequential Read (Q1T1): 119.1 MB/s Sequential Write (Q1T1): 113.7 MB/s Random Read (Q32T16): 4KiB 0.573 MB/s Random Write (Q32T16): 4KiB 1.290 MB/s Random Read (Q1T1): 4KiB 0.505 MB/s Random Write (Q1T1): 4KiB 1.305 MB/s REAL WORLD COPY: In my real world copy test the new My Passport drive was just noticeably faster than the older My Passport Ultra. More on the writing than reading side and more noticeably with smaller files than larger files. It peaked out at about 70MB/s with large files. I never dropped below 35MB/s even with large amounts of small files being copied to the drive. The 2016 My Passport Ultra peaked out at about 68MB/s and dropped several times to 30MB/s. I'm thinking the newer drive may have a larger on-drive write cache or maybe it's just a bit faster drive. Maybe both. On big copies the new My Passport may save you a few seconds here or there but if copying a lot of small files to it the difference was much more noticeable. CONCLUSIONS: The My Passport line of drives from Western Digital has been very good to me and to my clients. This reliable and good to excellent performing line has a long positive history with me. This WD My Passport model is an evolution over the 2016 My Passport. I'm picking it for new purchases over the older model, but won't rush out to replace older drives. I like this 2019 My Passport’s rounded corner case better than the 2016 sharp edged and glossy one, but it's very minor point for me. Overall it's an excellent evolution to a 5 star predecessor and continues to be a very good external storage choice. For making improvements in small file write performance and correcting the 2016 bad case design issue this new 2019 generation of My Passport drives is worth 5 stars in my opinion. Hope this helps someone!

Got this to backup a network drive shared across our family and it's perfect. Speed reaches 120mb/s on average with a mixture of documents and large media files. For 4TB of space, the price is really good. My only issue is that it doesn't have USB-C. Other than that, it's a really good portable hard disk.
