Fast enough to store video recordings, edit from and store standard pictures. Been using it to store media and let me save 100gb of icloud storage, way better than subscription based cloud storage

Upon acquiring this storage device with the express intent of housing my collection of PC games, I observed that the process of game installation proved somewhat protracted. However, I am heartened by the fact that this is a one-time undertaking, and I am suitably impressed by the swiftness with which games can be loaded thereafter. That being said, I must acknowledge that the price point of this device is, perhaps, a bit on the steep side.

I bought this when it was on offer for 95, as I’d recently also gotten an iPhone 15 Pro Max, and wanted to make full use of the video recording capabilities.

For the purpose I bought it for, it performs fantastically. It’s even fast enough for me to reliably scrub through footage in Davinci Resolve Studio on my Macbook Pro without having to move the footage off of the drive.

I’d recommend it even as a general external storage drive, but if you’re looking for something specifically for video recording, this is ideal as the port on the iPhone 15 Pro Max provides enough power for the drive.

Loved the size. Perfect for attaching to iphone for direct ssd recording. Whatever the iphone throws at it, it can handle. 4k Pro Res 60 fps? Bring it on.
Best thing I have bought since the iPhone 15 pro max.

Simplicity itself to set up. Transferring my data ( music, photos ) took a while, there is a lot and my pc has mechanical HDD, once it had completed the transfer, the access and retrival of information from the SSD was very fast, certainly faster than any HDD I have owned internal or external. It is amazing to think that this SSD can hold the entirety of my Barracuda HDD and then some on a devide that is about the legnth and width of a business card, albeit a little thicker. If you are looking for storage with bells on, Crucial X9 Pro 1TB Portable SSD

Advertised as just plug in and use – and that is exactly what I did – and it worked! I am using this as a back up disk for my iMac. Back up is automatic using Apple’s Time Machine and this now takes a fraction of the time it used to take with my old conventional hard drive disk.
This is a very small unit approx 5 x 6.5cm – which is amazing for a 1TB capacity. Others have commented on the short cable which comes with it – and yes, it is very short, but just long enough to reach from the back of the iMac to my desk. The cable plugged straight into the back of my Mac with no adaptor needed.

It simply wouldn’t work when it arrived. I copied off the files it already held, reformatted it and re-loaded the original files. I have had no problems since.

It is not as fast as I expected but fast enough. Its ultra-portability is the main benefit. It backs up my PC daily and I can always walk away with the latest information for use elsewhere. I hate trusting the cloud, this solves that problem.

I bought this to use with a Macbook Pro and video editing. Had footage from 2 projects on it when all of a sudden the Mac can’t mount the drive (but can see it). Now the drive looks like it’s formatted in NFTS (Windows). Macs should read NFTS drives but not be able to write on them. Anyway, I managed to get the files from the drive by attaching it to my Samsung smartphone (I don’t have a PC) which could read the drive. Then transferred the files from my Samsung to my Mac. Reformatted the X9 Pro to APFS and now it seems to be working… Hopefully it stays that way

I needed another 2Tb SSD for my Linux machine. Initial the SSD drive worked, but odd errors kept on occurring. It appeared the new SSD drive was faulty, however, I order a Ugreen usb-c to usb-c cable from Amazon and use it instead of the cable that came with the SSD drive. My problems went away, and for the past 4 days, the SSD drive is working perfectly.

I wanted an external SSD to transfer literally thousands of photos and videos dating back 20 years and stored on much older external mechanical hard drives.

I initially ordered the Sandisk Extreme 2TB drive, but when I tried to transfer a folder containing 1.3 TB to it, the speed was OK, but within a few minutes the drive got extremely hot (but continued working ok) but then after 2 hours it disconnected itself completely halfway through the transfer.

I then Googled the problem and saw that some other users had experienced the same thing, so I ordered the Crucial X9 Pro instead.

During the transfer of the same 1.3 TB folder, the X9 just got mildly warm to the touch, and completed the job without a problem.

I also have older Samsung T7 drives, which have never given a problem and transferred the same folder without difficulty, albeit about 20% slower than the Crucial, and running a little bit warmer.

The speed of both the Sandisk and Crucial were about the same: the long transfer time was due to the 15 year old hard drive they were transferring from.

And although the Sandisk started working again when I clicked on it after the self-disconnection, I didn’t want the stress of wondering if it would conplete a big transfer overnight without me sitting watching it. So the Sandisk Extreme has gone back and I’ll stick with the Crucial. In fact have ordered a couple more because I have so many historic files to preserve for prosperity. I’ve also tried some heavy duty 4k video editing with the Crucial and it works fine: again staying just slightly warm to the touch.
