SanDisk external ssd keeps disconnecting randomly

imac 2020 running Sequoia randomly disconnects my SanDisk ssd that I use exclusively for photos library backup. It's connected by a short USB C cable to one of the thunderbolt ports. This never happens to the TimeMachine ssd in the thunderbolt port just next door.

iMac 27″, macOS 15.3

Mac Studio M1 & SSD external Drives Disconnecting I've started disconnecting my old conventional external WD Hard Drives and upgraded to the SanDisk SSD external drives. They are 1TB and 2TB drives. Since doing so the last month or so, I've noticed that I consistently get notices alerting me that one or two of my drives are disconnecting and reconnecting on their own. I use 40GB 7-inch USB-C cables to connect to my Thunderbolt ports so I tried to rule out the cables as the culprit. The drives don't tend to give me any grief when transferring data to and from them. Has anyone else begun to experience this phenomenon? I just want to make certain I am not harming the Mac Studio or the SSD Drives.

External SSD disconnects by itself then tells me to disconnect properly My imac running Monterey vs 12.4 (Retina 5K 27" 2020) came with a 500gig SSD, It filled up pretty fast as I used the Built-in migration app to transfer the old imac to the new one. (kinda over loaded it)anyway,the ssd got near full. So.I bought a new SSD external drive and moved many files to. It Is there a way to stop the external ssd from improperly disconnecting itself? Oh, The new external drive is a "SanDisk Extreme Portable SSD 2 TB drive. Thanks for your help, Ron

USB-C external drive is very slow on iMac Pro but very fast on Macbook Pro Hi everyone, I have an iMac Pro in office and Macbook Pro 16" at home, both of them have 4 thunderbolt 3 ports. I'm using an Orico 512GB SSD External Drive for backup and work from both devices with the same files. The fact is on my macbook pro, Orico goes very faster, write 400mbs read 1gbs tested on blackmagic disk speed test. Same SSD same usb-c cable, on iMac Pro goes very slow, write 43mb and read 42mbs, tested always on blackmagic disk speed test. I did search about some similiar problem but did found nothing. What could be the problem? How I can solve it?

Try another cable (Mac is very sensitive to cable integrity) and also switch ports and test.
