That’s why I bought an esata drive over usb... before usb 3 came out it was great!

I would always go for any other option instead of USB if I had a choice. I was a die-hard FireWire user until drive cases became expensive and fragile.

This computer is a late 2009 Mac mini, so I was quite limited when it came to expansion due to the small size and limited expansion options. That never stopped me from doing things like adding more memory than Apple said was supported, or running a secondary hard drive from the SATA port for the optical drive. In the past I ran a short extension cane externally to make that happen, but since purchasing the SSD I just put the previous hard drive in a tray that mounts in place of the optical drive, and now everything is internal and neatly tucked away. I now need to get a case for that 1.5TB that was my secondary hard drive; as a 3.5" unit of wasn’t going internal.

I did go for eSATA to add an SSD to my old MacBook Pro. The optical drive tray option didn’t work nearly as well on this computer since that isn’t a SATA connection. At least there’s no moving parts, so if it gets bumped it’s not a big deal unlike how it would be if it were a conventional drive.

I do put USB3 on every PC I build or work on if it’s not standard. My main desktop machine has two ports, but I’ve added another seven, just in case. I have a couple of older Dells that didn’t have it, so I added it using a remote PCIe slot meant for a wireless card. It’s weird but it works. No manufacturer is going to put in an expansion slot and make me use it in some limited fashion, nosiree. The HP has a mini-PCIe slot on the motherboard, like you’d find on a notebook, so I stuffed that with wireless and Bluetooth even though I could do those easily through USB. Gotta use every single possible slot - that’s just my way.

I always run my peripherals on 15-pin Serial.

I think the retro hipster computer geek option would be to do it all daisy-chained off the parallel printer port. The one t thing you can’t connect there would be the printer - too common, like they wanted you to do that...

I have not seen a Cruzer drive like that in years, they were all the rage in 2006.

USB 2 was rated at 480 Mb/s while the first version of FireWire ran at “only” 400 Mb/s, yet FireWire could transfer data at close to its rated speed while USB choked at a little bit over 100 Mb/s. Intel kept the polling protocol used in USB 1 when they developed USB 2, resulting in high CPU load during transfers. FireWire places a smart controller on each device, allowing fun tricks like direct device-to-device transfers and remote DMA without requiring CPU intervention. SATA is closer to FireWire in this sense.
