  • 2 TB SSD by Crucial.
Capacity: 2TB Style: X9 - up to 1050MB/s
Small size, convenient and fast enough for my use. I have a few of these for backup and they work great. I’m not interested in what’s on the drive when I receive them, so I immediately format to exfat and I’m good to go. The one I use for Mac TimeMachine I formatted to APFS.

  • A couple of not so good
Capacity: 1TB Style: X9 - up to 1050MB/s
I’ve known the name Crucial for about as long as I’ve been in the computer business yet I can’t say for sure if I ever ordered from them by brand. I do know their reputation is good. I’ve been spending my spare hours cleaning up files on my endless array of hard drives and SSD’s, I just got finished cleaning 205,000 files and I have more to go. One of the pitfalls of being a professional photographer and cinematographer and running a business is managing a lot of data. Today I went to open an often used Excel file and guess what, it was gone. And it was a super important one. So I stopped everything and did something I have meant to do for a long time. Get this SSD to do continuous backups of those things that I absolutely can’t lose, ever. I do have a good manual backup routine, hence all those backup drives but what was missing is being able to keep a history of my work on a daily basis I wanted something small that I could plug in to one of the USB-C ports of my Z2 G9, a very capable workstation. I have three such fast ports so no worries there. I didn’t need anything fancy or a cool belt lanyard or bright colors or lots of fluff ware and I don’t plan to drop it but there are no moving parts so that doesn’t concern me. What I did want is speeds keeping with the latest standards, because why not, and I wanted media that’s as relatively safe as possible, which I will never believe is a hundred percent possible with any storage drive, disk or solid-state. I scoured as many tech articles as I could find and the X9 seems to be one of the most highly regarded there is. I avoid the brand that starts with s because it seems everything I buy from them I regret and I try not to do business with them. THE NEED FOR SPEED I stay miles away from any discussion having to do with speeds for a gadget like this. It’s all a game with no winner. It’s like saying my brother can run faster than some guy in Cincinnati or my Yugo is faster than yours. There is only one answer to storage media speed – your speed will depend on stuff. Everybody’s computers, phones, files, and everything else are different, and a bench test is just that, unless that’s all you’re going to do with this thing. In real life the speed you get will depend on stuff. Knowing my workstation’s ports can support it I did do a quick test and found that I was able to achieve some fast read speeds. Then in real life I did a full backup using TrueImage and my overall average was about 203 mbps. Any other speedy capabilities of this device were pretty much wasted. OH PLEASE This is where I air my disappointments. Why is this thing plastic instead of aluminum or magnesium or titanium? What’s inside is three cents worth of silicon, couldn’t they spend another five cents on a decent case? And, what happened to including a basic version of some brand of backup software? I got the impression from their poorly done product page that they were saying they include Acronis, well they do but it is so stripped down that it is for all practical purposes worthless. They push hard on upgrading it, but it’s very clear that Acronis’ target client base is the IT departments of major corporations not us lowly consumers. The upgrade process went terribly, Unlike other software if you don’t pay the annual ransom they deactivate the whole product instead of letting you continue to use it. That subscription includes some questionable virus ware I don’t want or need, automatic renewal and worst of all it is set to allow them and anyone they sell your information to the right to spam you forevermore. And if you change your mind one second after paying for it you’re out of luck, they won’t give you your money back. They also include a three month trial of some photo cloud storage app that I would never use for my client work because of privacy concerns. And oh yeah, they will give you a whole whopping month of Adobe if you give them a whole lot of private information and agree to get their ads pushed to you by email. Storage Executive is another app you can download. I found it of dubious value, it features things that I can already do on my computer without having their app in the way, and by installing it you give them the right to automatically get access to your SSD for upgrades, this also is a privacy concern to me. Although this review is for the SSD, if my intent is to use it as a backup device, I found it was necessary to discuss this company’s poor choices when it comes to their embedded software apps. If you don’t use them this doesn’t apply to you. YES NO MAYBE The case is very lightweight and angular in shape, and very lightweight. If I bought this as my travel drive I would have been very disappointed that it is plastic. And I may have been disappointed that the included C-to-C cable is only a few inches long. But the cable is good quality, with strong strain reliefs and a robustly braided covering. I used a piece of #M Command tape to mount the drive to the bottom of my workstation where I could leave it permanently plugged in to a dedicated data port on the back of the computer. And I spent the thirty-nine bucks to get a paid version of TrueImage because it works for me. With my x9 mounted out of sight it is always plugged in and backing up, that was my intent when I bought this so overall I am fully satisfied. Despite the things I wish they would fix how can I say no to this thing? It’s a piece of functional gear that I need and it has a job to do. If it ends up not doing that job it goes back and I let the world know, wimple as that. ... show more

  • Fast and Fantastic storage option.
Capacity: 1TB Style: X8 - up to 1050MB/s
In our office we have 6 people producing and editing short format video content. Most used Mac, some used Windows and all of them were using their own external SSD or HDD for storage. I was so tired waiting for them to transfer content that I bought 4 of these to give to our editors. I have probably saved enough of my own time in 6 months to make the expense worth it, let alone their time. Don't use slow drives. Don't use slow older USB standards. They waste your money. These Crucial drives are great and fast and made all my editors very happy, with brownie points for me. ... show more

  • Pretty fast drive, 4TB model
Capacity: 4TB Style: X8 - up to 1050MB/s
So I am including my benchmark. You will see that this drive is a bit slower than the other benchmarks and likely because I already have over a TB added to it. I have two devices on my 3.2 on board motherboard USB controller. Processor is i7 10700 and 32GB RAM. Write caching turned on. This is about half as fast as my older internal NVME .M2 SSD and as you can see pretty much in line with other benchmarks and what I expected. I set a goal to replace all spinners on my desktop except for one drive that I use as a backup. This was probably the easiest upgrade possible and I replaced my 2012 2TB USB 2.0 drive finally. As for this drive it does not get hot at all. It is surprisingly heavy and solid feeling. I guess I am used to cheap crap these days, so feeling that the drive was made of great materials and had heft to it was very nice. It is extremely responsive but to be fair I haven't done anything demanding. I did turn on write caching before running the benchmark but I have no idea if that's necessary as SSD's are usually 🔥 in the performance department. If I ever start having issues with this drive I will update my review as drive failures are a huge pet peeve of mine. For now 5 stars. 30 years in IT, etc. ... show more

  • Very small and portable
Capacity: 1TB Style: X9 - up to 1050MB/s
Working well . Good price. May buy another as a backup backup... Solid state, doesn't seem to heat up. Very fast transfer. Recommend getting a USB to c adapter most computers still have USB ports c not as common.

  • This thing is small but hold pictures...

I resolved the problem of storage my pictures, it holds thousands of pictures and videos and still has 3.2 tb left, my only concern is that one day this thing doesn't work anymore and I will lose all my pictures and videos, I hope it never happened while I'm still alive 😂😂😂😂

My computer guy told me to use this as my external hard drive. So far, so good, but the best feature is its size.
