Home security system with USB 3.0

[kron]

I'm looking to get a home security recording system with an expandable storage capability via USB 3.0. This is because I have a 4 TB Seagate external drive that I'd like to use. The Seagate drive will operate on USB 2, albeit at a slower speed.
I was looking at the Amcrest 960H, but the expansion port for that appears to USB 2. (https://amcrest.com/amcrest-960h-4c...KwlqA8I-9LcVIfvs6x2ZixQfGl1siQVSrkhoC3YPw_wcB)

Does anyone know of a bring-your-own-disk system, or one with a USB 3.0 expansion port?

Thanks.

The limitation is the crappy amcrest dvr, not the USB 2 connection. You would need roughly more than 40 960H cameras streaming simultaneously to bog down the USB 2 connection.

I know you want to use your external 4TB hard drive but that will limit your options.

Here's what I would recommend:
1) Concentrate on quality cameras such as Hikvision, Dahua, etc.
2) Buy Blue Iris software or get an NVR.
3) Register and post here, friendly and helpful forum

Later this summer I'll be outfitting our house with this awesome camera:

You don't need all that
