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.

It's physically tiny and light. It's like a matchbox or something. But yeh it's fast as anything. Using the seek bar on movie files is immediate. Love it.

Works well have several games installed on this, plugs via usb-c at the rear of my machine so dont see it, was a lot smaller than i thought but thats works for me, will fit in the palm of your hand. fast and responsive for gaming. no issues.

I’ve always trusted Crucial drives and this one continues that streak – fast, compact, and rock-solid reliability. My only gripe is with iPad Pro (M4) compatibility: some folders won’t open on the iPad, even though they work perfectly on my Mac. It’s the same issue I had with my Crucial 4TB, and the only workaround is to take files out of the folder and place them elsewhere on the drive. That makes video editing clunky when you need everything neatly in one place. On a Mac it’s flawless, but on iPadOS it’s less than ideal.

Waterproof! Been using this for over a year. Compact, fast and after it accidentally went through a whole machine cycle, complete with cable, everything survived.

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

I’ve had this for less than 2 whole months, was working just fine yesterday. Backed up all my data and deleted a lot of it off my hard drive to free up space. Less than 12 hours later it no longer mounts onto my computer! I’ve tried different ports and different cables, both on 2 different computers and it refuses to mount. The cables work with my other drives, the ports work as well on both computers. It’s just the drive itself. It looks like the middle bit of the port in the drive has moved or come loose, which is most likely the reason. WHY THOUGH!? WHAT IS THE POINT OF A BACKUP IF THE BACKUP IS SO BLOODY FLIMSY!? This is absolutely absurd! I’ve now lost so much data I needed, photos and videos of my daughter, EVERYTHING! 2 WHOLE TERABYTES OF MY DATA ARE GONE! Do not trust this drive and I will never buy crucial again!

Love these, they're fast enough for me until you get into really big files. Sending large files of over 100GBish will end up in thermal throttling. Other than that, they're still brilliant and i use them every day. Great value for money, good options for storage, silent operation.

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

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

Per il momento, SSD perfetto. Comodo, compatto, tutto sommato la velocità è decente (non velocissimo ma era dichiarata la cosa, peraltro utilizzo un vecchio computer che non mi consente di sfruttare appieno le caratteristiche). Sicuramente il miglior prodotto su Amazon rapporto qualità prezzo. Penso ne prenderò un altro

The Crucial X9 1TB Portable SSD is excellent. It offers very fast transfer speeds, strong security with reliable data protection, and stable connectivity through USB-C. The compact design makes it easy to carry, and it works smoothly with both laptop and mobile. Great value for money and perfect for backups or daily use. Highly recommended!

【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。
