Crucial X9 2TB Portable SSD, Up to 1050MB/s, USB 3.2 USB-C, External Solid State Drive, Compatible with Windows, Mac, & Android, Reliable Storage for Games, Files, & Backups, Black - CT2000X9SSD902

I love this SSD drive. I use it multiple times daily, and it works so well with my Windows 11 computers. I have used multiple backup drives that were HDD and would have to replace them within a short amount of time because of using them so frequently. I store all my family files on this SSD and use it as our external backup for receipts, passwords etc. This is the first SSD drive I’ve used, but so far, I can say I’m a convert and even though it’s definitely an investment upfront it has been worth it. I’ve had this drive for almost three months. It still works just as quickly as it did on day one, I’ve not had any data loss, it’s easy to hook up and remove from my computer, and it’s black and small enough to easily fit in a purse/bag or a suitcase if I needed to take it with me. Although looks weren’t as important to me. It’s also extremely quiet. In fact, to hear noise from the SSD drive I’ve had to put the drive right up next to my ear, and even then, I heard very little noise. I would highly recommend SSD and especially this Crucial one. I will purchase again if the one I have dies or if I need an additional one.

I’ve been using the Crucial X9 4TB Portable SSD for a few weeks now, and I’m seriously impressed. For those who want big storage without bulk, this is it. ⸻ What I love: • Compact & lightweight — It’s so small and thin, it easily fits in a jacket pocket or laptop bag without adding bulk. • Massive capacity — 4 TB gives me peace of mind. I can store video files, large photo libraries, backups, games, etc., without constantly juggling what to keep or delete. • Good speed — It delivers up to ~1050 MB/s (per Crucial) for sequential reads, which for me has meant fast transfers of large video files. (Of course, your speed depends on your USB-port, etc.)  • Durability — It has IP55 water/dust resistance and survives drops to about 7.5 ft / 2 metres (on carpet). That gives me confidence using it on the go.  • Compatibility — Works seamlessly with Windows, Mac, Android, etc. The USB-C interface + USB-A adapter makes it flexible for different devices.  ⸻ What to watch out for / minor drawbacks: • Speeds vary — It’s great when connected via a high-speed USB-C port, but if you use older or slower ports, you won’t get top performance. • Price — Naturally, a 4 TB SSD like this comes at a premium vs smaller drives or HDDs. If you don’t need all that space immediately, you might find smaller capacity options more cost-efficient. • Heat / throttling — I didn’t notice big issues yet, but as with many portable SSDs, heavy sustained transfers can warm it up. Just something I keep in mind. ⸻ Bottom line: If you’re after “big storage in a tiny package”, the Crucial X9 4TB hits the mark. Excellent for content creators, frequent travelers, or anyone who doesn’t want to worry about running out of space. Definitely worth the investment in my book.

This is the smallest SSD I’ve ever owned — seriously, it almost doesn’t feel real when you take it out of the box. I’ve been using it for 4K video editing and it handles everything without a single hiccup. Speeds are great, files load instantly, and I never feel like I’m waiting on it. What surprised me the most is how lightweight it is. It can literally hang off the cable on the side of my laptop while I’m editing and I don’t even think twice about it. For anyone who needs fast storage in the smallest form factor possible, this thing is a no-brainer.

CrystalDiskMark reports max sequential read of 1067 MB/sec, and sequential write of 1039 MB / sec. Sustained transfers from NVMe to the drive through USB 3.2 Gen2 run about 650 MB/sec. CrystalDiskInfo reports operating temps while powered on and idle around 40-45C, even under a heavy load operating temps never hit 70C. Comes preformatted in exFAT, which ensures compatibility across different devices and OS environments (PC, Mac, Linux, Android, etc,) so if you aren't the most tech-savvy person, it will work well to plug and play right out of the box. This thing is unbelievably small, just a little bit bigger footprint than two USB sticks side by side, and has a smaller footprint than a credit card. Virtually no noise when in operation, because SSDs don't have any moving parts. The only drawback is that the housing is plastic, metal would have been nice for durability and to help with heat dissipation. If I were going to transport this drive frequently, I'd invest in a protective sleeve of some sort, just to prevent the possibility of the housing cracking if it was dropped on a hard surface, but for typical use it should hold up just fine. Any drive can and eventually will fail, and every drive model is going to have a certain amount of defective units, but I've written almost a TB of data to this drive, and so far, so good! I'll update this review if any problems become apparent, but thus far, this seems to be a quality SSD at a great price!

I bought this to replace an old USB 3.0 external drive. This drive is much nicer. It's less than half the size and so much faster! I would have liked something bigger than 2 TB, but the prices haven't come down quite enough yet. I thought the price of this drive was reasonable, and it's doing a good job for me. I am considering purchasing another one

Crucial is a known brand when it comes to memory upgrades. When I received this eternal drive, I was a bit disappointed -- it looked so small I thought it might just be an adapter or internal memory. But it’s the real deal: Compact and lightweight enough to dangle from a laptop by the USB cable. It might not be the fastest SSD, but its factors better than an HDD. It came preformatted in ExFAT, but I switched to NTFS to better suit my performance needs. At this price, it’s a bargain -- and I’m already wishing I’d gone for an additional 1 or 2TB.

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

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.

【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。

My mechanical backup drive started clicking and became veeeeery slow (I use it as a Time Machine disk) so I decided to get an SSD. The Crucial one was, frankly speaking, cheapest. I have no regrets. The initial backup (850 GB) took an hour – with the mechanical drive ‘preparing backup’ could take an hour. Suddenly, the incremental backups are almost a pleasure. I just did one. 20 GB took four minutes. I don’t even want to know how long the mechanical drive would spend choking on it. The only ‘problem’ is that it’s so tiny it’s barely there. I put it in a textile bag not to lose it. The cable is very short, but the drive is so light it can safely dangle from the laptop while I’m using it in my lap. The speed is amazing, I can hide the disk in a matchbox, and… and that’s it so far. Now let’s hope it’s as durable as it is cute and fast.
