I've found that I only need to shape upload and I get almost all the bufferbloat benefits, while reducing CPU requirements because download is not shaped. Thus, a $15 router with a slow CPU can be fine for fixing bufferbloat.
Someone created a site that compared flash memory storage prices (USB stick, SD card, SSD) and they posted the link in some comment, but I can't find the HN comment and a Google search doesn't find it either.
"Glib advice aside, what is the recommendation when it comes to sleep and alcohol? It is hard not to sound puritanical, but the evidence is so strong regarding alcohol's harmful effects on sleep that to do otherwise would be doing you, and the science, a disservice. Many people enjoy a glass of wine with dinner, even an aperitif thereafter. But it takes your liver and kidneys many hours to degrade and excrete that alcohol, even if you are an individual with fast-acting enzymes for ethanol decomposition. Nightly alcohol will disrupt your sleep, and the annoying advice of abstinence is the best, and most honest, I can offer."
