I have an older Dell R710 for my personal home server with a pair of PERC6i raid cards in it. I have a drive array attached to one of them where the data lives on different RAIDs, the other PERC6 is attached to the R710's 8 drive bays.
I'm abandoning tape as a backup and moving to disc drives, which I will rotate off site. I am trying to figure out which would be the faster device. In both cases, a spinning drive, not a SSD is preferred as I've read many SSDs can lose their data when shelved, and powered off. I understand that is less likely with a regular disc drive. So, assuming similar drive specs, which would be faster for throughput:
a) A PERC6i connected drive running raid 0 (single drive) or
b) Add a PCIe USB3.0 card and use USB 3.0 (or USB C) external drives.
Cost-wise they are similar. The latter USB 3.0 option is probably more convenient, readily portable, and has broad compatibility with a restore or access. But, an external USB 30 non SSD drive may be hard to get before long.
If the hotswappable drive bay is faster by much, I can get some drive caddys and use that as my backup device..
I'm fuzzy on what should be faster. I gather the PERC6 is a 3 Gbps device while USB3.0 can do 5 Gbps. The R710 manual says that PCIe gen 2 is supported, there are 2 PCIe x8 slots and I think that limit is 500MBps so I assume the PCI won't be a bottleneck to USB3.

I would use USB if you need to get your data offsite, not for speed reason, but to be practical. Hot swapping the USB disk is easier in the OS to manage, versus the hotswap of an internal HDD, where if you insert a new one you have and to create the array and attribute a letter to it. You might have to script that part, so the USB option win, even if it can be slower.
Not to forget that if you restore, you would need a Dell hardware to read your backup, versus the USB disk that you can read on any servers.
