Seems like we need a USB equivalent standard to RAM sticks. I have lots and lots of old (1-2GB), intercompatible sticks sitting. Sometimes you just need the space and not the speed.
No, we absolutely do not: https://en.wikipedia.org/wiki/USB For starters, The slowest sticks of DDR(x) are often slower than DDR(x-1). The issue is never capacity, but rather, performance. The real nonsense? USB? It's a mess. Pick a USB cable and buy it from ANY retailer, let's make it easier, buy a USB-C cable. What is the data rate (depends on cable quality and length), Does it support power delivery? If so, how ma…
Okay, let's assume it's a USB-C cable and not just something USB-C shaped that pretends to be one.
> Does it support power delivery?
Yes.
> If so, how many watts?
Always at least 60W (3A). Up to 240W if it's e-marked.
> What is the data rate
Depends whether it's a USB 2.0-only cable (480Mbps) or a complete cable (20Gbps). Possibly more in Thunderbolt or USB4 modes - cables that handle those will be marked (both visually and with an e-mark). In any case, pretty easy to check just by plugging things in.
