D5-300 Copying slows, halts, then crashes the computer

[jonmgreen]

Hello,

I just purchased the D5-300 with 5 WD 8TB Red drives.
I went through the configuration process as described, the drive was all setup fine.
I started to copy files, it was going very fast, then it slowed down, eventually pauses copying, then a few minutes later the entire computer crashes and restarts.

I'm running a 16" MacBook Pro on Catalina, 10.15.7
I'm using the original cable with the Apple USB A to USB C adapter, and I've seen no issues with it and other drives. No other external drives cause this issue.

Can you let us know from which device you copied to which device. Are your other devices also high-speed transmission devices? Does your Mac ever have problems with high-speed transmission? Of course this is just a guess, but it would be nice if you could try it out with some other high-speed transmission device. Also, are you using an original power source and an ac environment that meets the requirements?

Maybe your older device doesn't support fast data transfer, I recently bought the same model SSD from an online store by using a Computer Accessories Coupon and it works perfectly on my system.
