250GB Portable External SSD,Portable SSD USB 3.2 Type C Ultra-Light External Solid State Drive, Mini Portable Solid State Drive for Mac Windows Android Linux(250GB)

This drive is pretty speedy! I'm running my Raspberry Pi 4 from it, and I'm quite happy. Note that you can't BOOT the pi from it, but you can have the next best thing.... You can run your RPi from it, but you do have to do the initial boot from the SDCard. Once booted, though, all the disk access is on the SDCard. A couple of things to be aware of: 1) This drive is a 4k sector drive. This means just burning an sdcard image with RPI Imager or Win32 disk imager WILL FAIL. They seem to expect 512 byte blocks. It just writes a corrupted filesystem to the drive. 2) It works fine after boot. 3) I tried everything I could think of, but the RPI4 will NOT boot from this device for some reason. 4) Not all is lost - you can move your / filesystem to the SSD and gain the speed and durability advantages. You will have to book from the sdcard, however. I tried every way possible to boot from it, but could not get it to work. I even manually created a FAT32 boot partition and a copy of a root ext4 filesystem by hand, and it would not boot. Here's how I got it to work. Steps taken on the Raspberry Pi: delete original partition on the SSD and create new ext4 partition with gparted (gparted usually needs to be installed) mount the SSD ext4 partition (I used /mnt/target) copy the current OS partition to the newly created on on the SSD. (I used "sudo rsync -axv / /mnt/target"). This takes about 5 minutes on my pi4B get the PARTUUID of the SSD ext 4 partition you just copied. (I used "sudo blkid" and found the PARTUUID for the partion on /dev/sda) backup /boot/cmdline.txt to cmdline.sd edit the /boot/cmdline.txt, replacing the PARTUUID with the one you just found for the partition you created on /dev/sdaX edit the fstab **ON THE SSD** and replace the PARTUUID for / with the SSID you just put in cmdline.txt. (I used "sudo vi /mnt/target/etc/fstab") Don't edit the regular /dev/fstab! Because of the change above, it will never bee seen. Again! Edit the fstab ON THE SSD filesystem you just created. reboot. You can confirm the device is running on the new SSD by using "findmnt -o -n SOURCE /" and it should show a partition on /dev/sda Has been running OK for me for a while. Search raspberry Pi Forums for more information and detailed instructions.

Bueno, funcional, barato compacto y perfectamente portable. Justo lo que yo queria

It isn’t as fast as advertised, the size of the device is good and the size of the hard drive are fine, as advertised. It worked mediocrely for maybe two months and now it is useless. My computer will not recognize the device, no matter what I do to reformat it or get it to reset and work it will not work. I wish I had sent it back when I had time.

After upgrading to a 256 from a 128 I needed something to store my old SSD. Well this is just what I wanted & needed. Yes, its USB 3.0 🤷‍♂️, Yes, its ALL-METAL housing, YES it fits 25 & 50mm M2.-SATA. "AND" it's no bigger than a zippo! 😉 Its great. All you need is in the packaging you take care of business. The only thing I needed was a case to travel with it and any mini earphone zipper case is perfect. After installing the old SSD in the enclosure there is even enough room to put some thermal pads, 0.5mm over the chips and NOT interfere with closing it up. While the USB 3.0 speeds might not be what USB-C is it works just fine for travel Laptop storage. IF you have a phone that supports OTG get the USB-C ver' Considering this is somewhat older tech by todays standard... you could... buy an SSD + this enclosure + a case & have a portable storage for less then say a 'WD 1tb mechanical' drive...😁😘 All in All I have 2 of these and they both work just fine for what they are. A place to store data on the go and fit in a pocket/bag then move on. PS yes... they do get a little warm after LARGE file transfers. But that's normal for silicon chips inside a metal box🤣

This drive originally didn't show up on my desktop on my MacBook. However, it did show up in Disk Utility. The solution was to right click on the drive icon in Disk Utility and click on mount. From that point on, it showed up on my desktop and has worked fine, with fast write speeds since then.
