Randomly disconnects = chance for data loss
Though the filesystem plays a role. I have a full metal body Sandisk USB stick that still overheats after a while and then disconnects (has a heatsink on top now) but ext4 handles that fine. I know that Fat32 has no journaling and NTFS is a tad bit sensible to disconnects. Don't know about exfat.
My external SSD I put together with a “nice” enclosure started dropping to 5MB/s on any machine. I don’t trust most external SSDs anymore.
I DO trust my RPi case with built-in m.2 USB adapter thingy, as it’s running full speed in that thing, no issues with speed dropping.
I'd like to know more about this adapter thingy.
Oh it’s AMAZING. It’s an expensive case for the Raspberry Pi 4 models, called Argon. It’s 45USD or so. BUT! It CHANGES THE SHITTY MICRO HDMI PORTS INTO TWO REAL HDMI PORTS!
It also has a little slot for an m.2 SSD inside it, and a tiny USB connector to make it work with a Pi. You can super easily boot from SSD and use a microsd as extra storage. It’s like 10x faster than microSD, it’s wild.
I had bought a different case (that honestly I love) but when I read about this one, I fell in love. Only problem is it only takes SATA m.2 drives, which happened to be the kind in my shitty enclosure.
I did something similar and use these UGreen enclosures with an M.2 on each RPi in my cluster. You can easily use these as portable media with whatever SSD you want.
Sorry, on mobile and have no idea how to strip the Amazon link properly. This is the older model I got.
UGreen on Amazon
You can buy straight from them as well. Never had an issue with any of their products. https://www.ugreen.com/collections/hubs-docks/products/ugreen-m-2-nvme-sata-ssd-enclosure-reader?variant=39915665129534
It's my biggest peeve with owning this SSD. I can leave it over a weekend and come back to, no lie, 50+ disconnect notifications from MacOS. Shoddy software to say the least...
Ok, that's far too much.
I use an Asus enclosure and put in a WD ssd. The heat dissipation is better than the sandisk model and it stays connected pretty much always except during travels
Eh, wait, so it's heath related? Defective firmware causing overheating or too low limits?
Haven't had that issue, but definitely design related. Mine is a Asus rog enclosure which has better heatsink than sandisk
