Hardware: Optimizing Startup Disk Throughput on Linux -- SATA vs PCIe

Okay... BIG qualifier here: this post pertains to a 2008 Mac Pro running Ubuntu 18.04.5 LTS. If you're expecting some sort of cutting edge hardware review, this isn't it. However, I fetishize old computers and my 2008 Mac Pro holds well enough against contemporary computers that it can handle just about anything I throw at it as a web-developer in 2021. This computer has been an ongoing project, and I enjoy tweaking it here and there to see just how well it can keep up. I recently purchased some PCIe cards (adapters, really) to run hard-disks on, and in this post I'd like to casually review which card, which drive, and which connection gets me the best performance. I'll also discuss what kinds of tools on Ubuntu/Linux help me assess this.

Background

Now, technically speaking, most of the information in this review could easily be found in product descriptions. Product descriptions, however, aren't always what they're cut out to be. I really prefer not to take it for granted that the maximum throughput listed on a product is the same as what you'll get on your own computer. It seems like there are enough variables in data throughput (reading and writing hard disks) that use-case is inevitably a factor. If my testing turns out to be redundant, that's fine.

Review: Raspberry Pi 4 -- A Desktop Computer?

Pi 4 as a desktop computer? Here are some initial thoughts as I sit down to play with the newest version of the Pi Foundation's single board computer.

Here's some background: I'm a little bit of a tinkerer. Nothing hardcore--but, I do fetishize older computers and anything  outside the fringes of mainstream technology. When my kids were in 3rd grade (they're twins), I caught wind of the Kano Computer and decided to get one for their birthday. If you're not familiar with the Kano Computer, it's a Raspberry Pi based hardware setup designed to allow kids (and tinkerers) a hands on experience with "building" and understanding a computer.
