If you add the mount option “sync”, it’ll skip the file buffer and write straight to the floppies (though there will still be a read buffer, which is more difficult to disable without it being system-wide). This will make for more floppy grinding goodness when writing files. You can also disable atime and relatime to improve performance (Access time/relative access time attributes). “mount -o sync,noatime,norelatime /dev/md0 /srv/www/apache”

Seeing an OS installed on Mega Floppy would be cool. Maybe Windows XP or 7 or something? I'd figure Windows 10 would require way too many floppies. Edit: I remember a while back seeing a video from Michael MJD about something called Tiny 7 that installed on 50 mb so that may be possible?

The sync command in that loop was unnecessary, it might be more effective to look into disabling the page cache for that specific drive/mount, or maybe just entirely, since the system isn't doing much else anyways. For running an OS off of it, I think it would be most interesting to just use a VM, and pass it md0 directly as the virtual HDD. That way, (assuming you manage to get a lot more drives as you plan to), you could run win95 from that thing and play some retro games. Should be way more interesting than just barely fitting a trimmed down modern Linux distro in there for the sake of having it bare metal. You probably have to give up on the G5 for that though.

One of the best parts of doing something like this is actually how many problems show up almost immediately so you can understand more of how RAID levels work and what goes wrong with them. You could configure regular spinny hard disks into a raid, but those problems might not show up for YEARS, and when they show up, now you gotta figure out how to fix that problem. But after doing something horrific like this, you probably know how to fix almost any problem that might come up

“We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too.”

6:23 "YOLO these into a raid" - I'm gonna have to steal that one lmao

Many decades ago, I was using an Intel 8080 development system. This was a large box with 4 - 8" floppy drives and a monitor. I think it ran some Intel disk operating system similar to CP/M and had assembly and high level compilers, debuggers, etc. Once you started building large programs, it was horrendously slow, at least trying to run off the boot floppy. Spent a lot of time trying to speed up the process and finally stumbled on the key. There was a "radial head load" jumper on the floppy drives. When that jumper was installed, if any drive was accessed, all 4 drive heads would load onto the disc and be ready to go. Then it was just a matter of spreading the various pieces of software among the drives. I think it ended up with O/S on the boot drive, compilers on another drive, source code on a 3rd and output files on the 4th. When you started a compile, there was a loud thunk as all 4 heads hit the deck then all you heard was the faint sound of the heads moving in and out and saw the various drive lights blinking on and off. It was such a huge speed improvement, since switching drives was instantaneous. Probably no way to do that with USB drives as each has it's own controller and they don't know about the other drives.

I lost it when you turned the cache off 🤣

Also, mounting with noatime probably would help, so it's not writing file access times constantly. In fact once the content is put onto the drives it could be mounted with ro so it doesn't ever write to it (except for some flags at mount time unfortunately). ActionRetro, without metadata on the RAID, I believe what happens is that the RAID doesn't know anything about itself, and entirely depends on the mdadm command to assemble and start it. Normally you can tell mdadm to "find and mount arrays" and it uses the metadata to do that; in this case you'll have to specify the exact mdadm command in the /etc/mdadm.conf file for it to find / assemble it at boot; and if you lose a drive, good luck figuring out how to repair it without the metadata, but fun for experiments in any case!

The ultimate OG nerd flex. No one else could or would try this except the 1990's era nerd. This is not an insult, I'm genuinely jealous that I've never thought to try this.

I wrote a 16-bit multitasking system and a TCP/IP stack and set up a http server using it and a 486 computer. Initially the website was served from a 360 kB 5,25" floppy disk, but I then installed a hard disk to the computer and now the website is on the hard disk. The main problem with floppies is that it takes a while to spin up the disk. After the floppy disk is already spinning, the bandwidth is about 30 kB/s, which is more than good enough for a web server.

Fun times!! Thanks for sharing

'To increase the data capacity of a standard floppy, Matsushita's FD32MB system employs zone bit recording -- a system used to encode data onto hard disks and optical disc systems that more efficiently uses the space to record data.' The new drive also supports SuperDisks for 240 MB storage capacity. A Google Search for 'FD32MB' turned up lots of stuff in Japanese. More details and discussion are available here starting back last November 2001" "According to the article which starts that PC Market thread, "The new technology increases the number of sectors per track to between 36-53 sectors, compared with its current number of 18 sectors, and its memory capacity per track can be raised from 9.2KB-18.4KB to 27KB."

If they used some form of modulation for recordings PSK (like modems) QPSK, QAM phase and amplitude modulation capablle get 4-8bits of 1bit digital data basically analog recording, they would probably get even more? Or they did that already? And if you use this for comparison - technically 90min casette tapes are capable to store 120MB (MP3 album, digital instead of analog) QAM256 almost identical to MiniDisk. And if you use this metod its not just my claim, proven by LGR tests, and later VHD digital you could store 1.5GB to even 5GB of data on 180min VHS tape. Depedning whenever you use original VHS video electronics or something better just use tapes. It was confirmed by LTO drives, it had same ammount of tape as VHS, just more narrow, like VIdeo8 and thiner. That Panasonic patent was pretty good result 32MB for flopy, still wont win with this RAID of wapping 40MB data :)

This is suuuuper pedantic, but what RAID 5 provides is *parity* , not redundancy. It allows for the use of CPU time to compensate for a single missing or corrupted stripe of data. If you specifically want *redundancy* , ie a second fully intact copy of your data to protect against not only hardware failure but also bit rot, bitflips and other forms of silent data corruption (which RAID 5 is not as effective against), you would want to use RAID 1 (or RAID 10).

Corrupted data on a physical drive will be detected because the data no longer passes the drive's internal CRC check and will reported as an error. Depending on your RAID hardware and/or software implementation, this may be corrected automatically or during a manual or scheduled array consistency check by reading the block from the mirror and rewriting the bad block. It's not perfect, but it at least gives your data a chance to survive.
