Say you have an 8TB drive with 6 platters - the option could be to pair up the platters and write alternate bytes to each, doubling sustained read and write
That would require the head to be right over both tracks at the right moment. I'm not sure the heads are physically aligned that precisely. Or are you suggesting to separate the head assemblies for the top 3 and bottom 3 platters and do RAID 0 in a box?
Would it be trivial to design a drive that can be switched into a double-speed half-capacity mode?
High RPM drives tend to have smaller capacity if I remember correctly, and any drive can be short stroked to save on seek time.
The way Slashdot hid a -1 comment made it appear as if
If you're replying to a post with a low score, especially Anonymous Coward, it may be a good idea to take a page from e-mail standard practice and state the nickname of the poster to whom you're replying. To fully avoid confusion, it might help to add multiple levels of quoting to provide enough context to interpret your post correctly even in isolation.
even so you can download an game off peak when some ISP are cap free
If you plan to go this route, satellite is in my experience far more likely to include unmetered off-peak use than cellular.
and you can say download an game / parts of it at places with free WiFi.
If your computer happens not to be a laptop, which is likely for a gamer because laptop GPUs tend to be underpowered in both senses, watch people point and laugh at someone bringing in a desktop computer to download a game. That's the vibe I get from Not Always Right, Geekologie, and Paradoxoff.
