Crucial X9 4TB Portable External SSD - Up to 1050MB/s, External Solid State Drive, Works with PlayStation, Xbox, PC and Mac, USB-C 3.2 - CT4000X9SSD902

I’ve been really happy with this external SSD. I mainly bought it to back up my important files, and it’s been reliable ever since. The 4TB capacity is more than enough for what I need. I’ve partitioned mine so that 1TB is dedicated to Time Machine backups on my MacBook, while the rest is used for storing photos and football videos. One of the best things about it is how small and lightweight it is. It’s incredibly portable, so it’s easy to carry around in a bag or even a pocket without taking up much space. The transfer speeds are excellent. Backing up large files is quick, and when I plug it into my MacBook, it only takes a few seconds before it’s recognised and Time Machine starts backing up automatically. That’s made backing up my data really convenient. The drive comes with a USB-C to USB-C cable, which is all I needed for my MacBook. The only minor downside is that the cable is quite short. If you’re using the drive away from a desk, it can leave the SSD hanging awkwardly, so I would have preferred a slightly longer cable. Mine arrived with a very small mark on the back, but it was only cosmetic and hasn’t affected the performance at all. It also includes access to some Adobe software offers, which is a nice extra, although I haven’t personally used them. It’s also compatible with modern USB-C devices, including newer iPhones, which makes it even more versatile. Overall, this has been a fast, reliable, and compact SSD that gives me peace of mind knowing my files are backed up safely. It’s definitely an expensive purchase, but considering the speed, storage capacity, and portability, I think it’s well worth it. Gaming note: I haven’t personally used it for gaming, but because of its fast SSD speeds it should work well for storing and running games on supported devices, depending on the console or computer you’re using.

Absolute dream to use, chain greased lighting when copying, small enough to slip into any pocket, very light as well, feels slightly plasticy, but the speed........ Used with a 2026 iMac, works a treat. Comes with little in the way of instructions, should you need them though there is a QR code on the package but my scanner said not a safe site so never downloaded so cannot comment on quality of the manual. Only other thing in the box is an 8" (20cm) USB C both ends lead.

The drive is very small and portable, its also quick, I bought this as an alternative to XBOX Series X expansion storage whilst you cant play series S or X titles it will play installed games for anything upto XBOX One. My only gripe was it didnt come with a A to type C cable in was a C to C so had to purchase a 3.2 Gen2 cable for it to work on my Xbox. Otherwise it only displays as a media disk with no format for games option. I feel if its being advertised as compatable with Xbox it should be out of the box. Technically it is but you need your own supported gen2 3.2 cable.

This was much smaller than I expected, about the size of a plug-in memory card reader. So it's very unobtrusive. I use it with a Mac and it feels very, very fast when connected to Thunderbolt, even though it's not the latest Thunderbolt 5. I saw a recommendation to format it in a specific way for Mac, which took less than a minute. So far it has worked flawlessly and feels almost as fast as the built in solid-state drive. It gets ever so slightly warm in use but you'd hardly notice it. I'm pretty happy so far though these things are harldly cheap. If it's reliable, I will be very satisfied indeed – only had it a couple of months so I'm not able to talk about long-term reliability.

I've been through my fair share of external hard drives and even a few budget SSDs, but the Crucial X9 1TB is the one that has finally made me stop looking. This little device is nothing short of spectacular, and it has become an indispensable part of my daily tech kit. Blistering Fast Speeds: Let's start with the most important thing: performance. The X9 boasts read speeds up to 1,050 MB/s, and in my real-world testing, it delivers. Transferring a 4GB video file from my laptop takes mere seconds—literally before I can even blink, it's done. Offloading a full 64GB SD card from my camera used to be a coffee-break affair with my old HDD. Now, it's finished in under two minutes. This speed revolutionizes my workflow, whether I'm editing photos directly from the drive or backing up my entire system. Feather-Light and Incredibly Portable: You have to hold this thing to believe it. It’s shockingly small and light—lighter than my car key fob. It slips effortlessly into the smallest pocket of my backpack or even my jeans pocket, making it the perfect travel companion. I never have to think twice about bringing it with me, which means my data is always on hand. Built Like a Tank (Despite its Size): Don't let its lightweight design fool you. The rugged, matte-finish exterior feels premium and durable. It's rated for a 2-meter drop height, which gives me immense peace of mind when it's bouncing around in my bag. I haven't (and don't plan to) test this claim, but it’s reassuring to know it's built to withstand the occasional accident. Universally Compatible & Simple Setup: The setup could not be easier. It’s truly plug-and-play. I’ve used it seamlessly between my Windows PC, my MacBook Pro, my iPad Pro, and even my Android phone (with a simple adapter). The USB-C cable is included and it’s reversible, so no fumbling around. The backwards compatibility with USB 3.0/3.1 means it works with older devices too, just at slightly lower speeds. Perfect For: Creative Professionals: Edit high-res photos and 4K video directly from the drive. Gamers: Expand your console storage with lightning-fast load times. Students & Professionals: Carry entire project libraries and backups without the weight. Everyone: The fastest, most reliable way to back up precious memories and important documents. The Verdict: The Crucial X9 1TB isn't just a product; it's an upgrade to your digital life. It eliminates the waiting and worrying associated with data storage. Pros: Stunningly fast transfer speeds (lives up to its 1050 MB/s claim) Unbelievably small, lightweight, and portable Durable, premium design with drop resistance Flawless plug-and-play compatibility across all my devices Includes a sturdy USB-C to C and a USB-C to A cable Cons: Honestly, I'm struggling to find one at this price point and performance level. If you're on the fence, just get it. You will not be disappointed. This is, without a doubt, the best tech purchase I've made this year. Five stars doesn't do it justice

Great drive very fast very good small size works with my pc windows 10 does not heat up after hours of use. Nice black colour compatible with all my devices.

This is awful. Transferred some videos and music files. That went OK but ever since everything on my laptop is really slow. File Explorer not responding. Playing music files and they cut out or jump after about 20 seconds, videos take ages to load and the keep stopping. Unplug the X9 and everything goes bak to running perfectly.

Worked perfectly out for the box. Really easy to use and connect using an usb-c port which is really fast. Surprisingly light weight for how much storage there is. I created multiple partitions using windows disk management to have a backup partition as well as a partition to use for DJing. It is fully compatible with both windows and my pioneer DJ equipment

Atendeu minhas expectativas, ele e pegueno e muito rapido seja a escrita ou leitura. recomendo este produto.

Best and the cheapest till now. The speed is amazing. I hope that micron revert their decision and doesn't stop its production.

Small, light and really portable. Copy speed is great too! Highly recommended. Thanks!

Si tratta di una SSD veramente piccola, praticamente ha una diagonale minore di una carta di credito. Le velocità pubblicate sono veritiere e il cavo usb C incluso è categorizzato come 10 Gbps, quindi ben maggiore di quanto serve per la SSD (il che è anche un valore aggiunto, benché sia abbastanza corto). In questo periodo i prezzi delle memorie sono rialzati per via della situazione AI, quindi non mi dilungherò troppo sul fattore economico. Dal punto di vista di velocità e portabilità, posso consigliarlo tranquillamente

【使用環境】 デバイス: Mac mini (またはMacBook Pro) M4 Proチップ搭載モデル 計測ソフト: AmorphousDiskMark 4.0.1 (設定: 2回 / 256MiB) 使用状況: 容量4TBのうち42%（約1.7TB）使用済み 【計測結果】 Sequential Read: 847.86 MB/s Sequential Write: 928.64 MB/s Random Read (4K QD1): 23.83 MB/s Random Write (4K QD1): 21.04 MB/s 【レビュー本文】 Apple M4 Pro搭載のMacに直結して速度を計測しました。 本製品は最大1050MB/s（USB 3.2 Gen 2対応）を謳うモデルですが、macOS環境ではUSBプロトコルの影響で速度が頭打ちになりやすい中、読み込みで約850MB/s、書き込みで約930MB/sという非常に優秀な数値が出ています。 ■ 良かった点 実効速度が速い: 10Gbps接続の外付けSSDとしては、ほぼ理論値の限界に近いスピードが出ています。特に書き込み速度が安定しており、大容量ファイルの転送も非常にスムーズです。 データが入っていても高速: 既に1.5TB以上のデータを保存した状態（使用率42%）で計測しましたが、速度低下は見られず、安定したパフォーマンスを維持しています。 コンパクト: 4TBという大容量ながら非常に軽量・小型で、持ち運びにも全く苦になりません。 ■ 気になる点 MacのThunderboltポート（最大40Gbps）に接続しても、この製品自体の規格が10Gbpsなのでこれ以上の速度は出ません。もし動画編集の作業ディスクとしてさらに上の速度（1500MB/s〜）を求めるなら、より高価なThunderbolt対応モデルやCrucial X10 Proを検討する必要がありますが、写真管理やデータのバックアップ用途であればこのX9で十分すぎると感じました。 【総評】 Crucial（マイクロン）製という安心感に加え、実測値も期待通りでした。特にAppleシリコン（M1〜M4）搭載Macユーザーの方で、「速くて大容量、かつコスパの良い外付けSSD」を探している方には自信を持っておすすめできる一台です。
