In External SSDs

Works fine on my iMac 2017, going through an old Belkin USB-C "hub" (fans out 1 USB-C port to 2, plus a couple other ports). I needed to replace an aging HDD used for my photos and other occassionally-written files.

Plug and play functionality Excellent value if purchased during a promotion Looks kind of cool

* Very small, smaller than even most other portable drives. I have two other external SSD's that are still slightly larger than the Crucial X9, and my portable HDD's are not only much larger, but also weigh significantly more. If your goal is to carry the drive around with you, the X9 is a great choice. * USB-C for fastest speeds. I don't believe previous generations of USB can reach 1 GB/s, so the newer interface is necessary to max out the drive. Running on USB-3 will certainly hinder performance. * Cool temperatures. Modern SSD's have a tendency to run hot, with many of them actually throttling bandwidth to manage heat. The Crucial X9 idled around 35C on my setup, and peaked at 50C during testing. Most SSD's have a maximum temperature in the 70-80C range, so there's plenty of headroom. I suspect there might be some kind of small heatsink inside the drive keeping it cool. * Blazing fast. The Crucial X9 achieved the highest sequential speeds I've ever seen on an external drive, rivaling many internal NVMe drives. I was able to copy large files at the full 1 GB/s bandwidth with no throttling so it seems Crucial has equipped the drive to sustain its maximum speeds at all times. My full bandwidth result is attached as an image.

Plug and play, copies over pix quickly. Was recognized by my iphone and did move a pix over.

(Tested with CrystalDisk Mark 9.0.1) Super fast and super small. As you can see from the attached picture, sequential read speeds averaged between about 430 to 464 MB/s. That is similar to m.2 onboard hard drives. As expected, random reads and writes were a lot slower but still very good.

Great price, fast shipping, works as intended.

Good transfer rate, great protective casing, easily portable. Excellent value for the money!

Easy set up, worked right off the bat, bought as a faster network storage for my router so it is easier to copy files from one computer to another on the same network. Small, light weight, usb C and normal usb adapter. For most uses, like PC's it'll just self configure and be ready for use when you plug it in, giving you a choice to add i'm assuming encryption sw for the device like other USB thumbdrives, for mac or windows.

Small size and protective case
