4-way stops is US/Canada only phenomenon, and it's really inefficient and stupid. Most sane countries use roundabouts instead

- I already have plenty of expensive and inexpensive headphones
- I was in several situations where ability to connect the my phone to the AV system saved the day
- Adaptors suck, get lost and may contain a low quality DAC.
- Others make phones with a headphone jack, why should I go for the inconvenience of buying one without?

Unfortunately they didn't. Otherwise I would tell them that it's very stupid for a newcomer to reduce the number of potential buyers without a good reason.

No headphones jack - no money

Please stop with the good enough jokes. We've heard enough of them, and none were good.

March 13, 2007? I don't think time machines existed back then. Maybe you write this on March 13, 3007?

Each hard drive has bad sectors detected during the QA testing and permanently stored in drives primary defects list (PLIST) table. The visible reallocations that start from 0 and reported by S.M.A.R.T are grown defects list (GLIST), not existing during the manufacturing. So yes, bad sectors are sort of a characteristic of disk drives.

It does a lot for manufacturing cost (BOM only - not counting the equipment and fab costs). However it does nothing for the price, which is a matter of supply and demand, and currently has nothing to do with the manufacturing cost.

$4 is less than even the BOM of an iPhone

Yes, there are PCIe cards with 4 m.2 slots (e.g. https://www.servethehome.com/the-dell-4x-m-2-pcie-x16-version-of-the-hp-z-turbo-quad-pro/).
And there are plenty of rack servers with internal PCIe switches for up to 24 U.2 (2.5") devices.

Software RAIDs (e.g, md or raidz) don't care if its SATA, SAS or PCIe, they only need the block devices.

1 Terabit/s divided by 20,000 is 50MBps per student (or even 53Mib/s if you are talking about binary Tebibit).
That's a lot.

United charged me about 25$ for 14-hour flight. And I paid in miles, so the actual cost was zero.
I bought the Wi-Fi for my phone and USB-tethered it to my laptop, so it worked fine on both devices.
The Wi-Fi was quite slow, and they tried to block all VOIP services and VPNs, but I still managed to connect to a VPN and make a very short phone call (just as a test).

I'm not a geek, but even I know what Knox and Odin/Heimdall are.
