JOIOT 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.

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🤣

I bought this JOIOT 500GB SSD drive to hook up for an additional backup drive. I never heard of this brand and the price is quite a value. I ran H2testw to verify that this drive is a real 500gb as they claim, the test passed. I then ran benchmark test to see if the speeds were close to their claims of: Up to 450MB/s read and 350MB/s write. Some benchmark and utility software have issues identifying the JMicron chipset used for this JOIOT drive. My initial benchmark testing came back terrible. I ran it again to confirm. I then decided to try and switch out the cable and use a different cable then what comes with the drive, huge difference. Using a different cable, the drive performs close to the advertised speeds. Using a better cable as you can see in benchmark picture attached, is about 2X-3X faster. Not sure why they would include a cable the under performs so much. The included velvet draw string bag really is a waste to include, samething you can get at any craft store. They should have included a better cable and skipped the pouch. The drive does run cool, has a small blue light. I'm going to hook this up for an additional backup drive and I'll adjust my review as I see how this drive performs over time. This drive is great value (so far). At the moment, I don't trust this drive with any data that I cannot lose. I'm just using it as an additional backup. That could change in time, but so far so good.

This little external SSD is absolutely amazing. The capacity you get in such a small size is extremely useful for storing tons of data in something you can toss in a pocket or bag easily. I haven't really hammered it, but performance seems fine. I'm using one on a Raspberry Pi 4 in lieu of an SD card. These are better than SD cards and even regular thumb drives because they have a controller on them which allows you to support functions like garbage collection and TRIM. If you just need something for carrying files then you may not care about things like that, but this will work in those cases as well.

I mostly use this to edit video off of. Store the files on it, and it feels about as fast as my internal SSD. Highly recommend. Purchasing another! (250gb version) ---update--- The above purchases were great, so i gave them to friends and bought the bigger version for myself. As soon as I plugged it into the computer, I've been having issues. Froze up my computer, crashed it. Super weird, because that's never happened by plugging in an external drive. I reinstalled my version of windows after, because everything got a little funny. I exchanged it for another 1tb version, and I'd say it works about half the time. I don't know if it's quality control, or the smaller sizes just work better, but really confusing. ------------------update again---------------- After getting into contact with the manufacturer, I believe issues are resolved! Bonus points added back for customer service, and day 1 of testing replacement drive things seem to be working as they should. Pretty stoked again!

Initially, I struggled to get this device to work consistently. It frequently disconnected, and after trying both NTFS and exFAT partitions, I finally discovered that the issue stemmed from the cable that came with the drive. The one in the picture is my own cable, which I originally received with an SK Hynix SSD. It worked well for a while, but then problems arose when I attempted to transfer data back to another computer. Although the copying process seemed fine, every file generated errors. I attempted this several times, moving files between computers, but the results were the same—nothing worked reliably! In contrast, I used a basic, inexpensive USB flash drive for the same process, and it functioned perfectly. Save yourself the hassle and consider using an Amazon Basics flash drive instead. It’s faster and completely worry-free.

Bought this for my Model X dash cam recordings. Initially it wouldn’t format. Kept saying issue formatting. Plugged it into my windows PC and same issue. Couldn’t format it. Windows reported the raw disk size just couldn’t format or make partitions (exfat wise as that’s what Tesla uses for the dash cam) grabbed another USB C to A cable from my stash and no issues. Went back to the original and issues again. So just a bad cable. Not a big deal. Still 5 stars as I didn’t even know it came with the cable.

This is a good drive while it works. I've had no issues booting Rasberry Pi OS on my Rasberry Pi 4, unlike some other reviewers. I have had it on 24hrs with my Raspberry Pi for a little over a year. Until it failed last week (1 year, 2 months). It still works, but it is a bit hot while on and locked itself into a read-only mode.

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