| Adding the MiniStack STX to my main system gave me a chance to rewire my office. And that meant buying some new cables. (You can never have enough cables.) My cable fixation has gotten so bad that, now, when I head out to run errands and my wife asks where I'm going, I just say: "You don't want to know." She immediately starts laughing, because she knows I'm off to buy cables.
But in this rewiring process, I learned several important lessons. First, that if a cable is cheap, it means that it just carries power for recharging mobile devices. Charging cables are fine, but they only transfer data around 30 MB/s - that's FireWire 400 speed!
When I connected the MiniStack to the Mac Studio, the SSD did not appear. Why? Because I was using a USB-4 cable, not Thunderbolt. If you have a Thunderbolt device, you need a Thunderbolt cable. A USB-4 device can use USB-4 or Thunderbolt, but not the other way around.
If the cable doesn't have a Thunderbolt lightning icon, it doesn't support Thunderbolt. Also, just because it uses a USB-C connector doesn't mean it supports high-speed data.
It got so bad that I spent a day speed-testing my cables using a Samsung T9 SSD and Blackmagic Disk Speed Test. I then labeled the cables so I know what I've got. And, yes, I trashed a number that only supported charging, to prevent future confusion.
In the past, protocols and cables were faster than our storage. These days, SSD storage is so fast that using the right cable makes a big difference. Given the cost of storage hardware, saving a few dollars by buying cheap cables often means that you don't get the performance from your storage that you expecte. This is a perfect example of pennywise and pound foolish, as I spent this last week learning. |
