the server performed great and I eventually made 2 more of them before we were acquired and the pros took over - what's funny is the pros only used dell servers and ended up having to go with some outrageously expensive top-end models to get the iops that my whiteboxes were delivering.
144 raptors in production for 3 years under heavy load and we never lost a single drive. we had the servers sent back to us when they were decommissioned and most of the raptors ended up in peoples' workstations for another couple years and I never heard that any of those drives ever failed.
Like, yeah, I get it. There‘s quite a few sounds that trigger emotional reactions in me.
The whirring and buzzing of the PSU. The Award BIOS beep. The seeking sound of an empty 3.5 inch disk drive. The slight CRT zang between different resolutions - and the electrical drizzle of degaussing such a beast.
But to this day nothing amazes me more than opening a MacBook and it being dead silent.
Maybe it‘s because I have young kids, maybe it‘s because I used to be an audio recording hobbyist (and isolating computer sound was always a pain).
But there‘s nothing I enjoy more than the powerful sound of silence.
Can I have fond memories while also appreciate modern hardware? Or they're just mutually exclusive?
Like you said:
> The OP is just reflecting on fond memories like you are.
In fact, if you read it again, you'll see they are acknowledging the appeal and fondness for computer noises of old...
SSDs are totally better, yeah. But it’s also kind of boring from a mechanical perspective. Insanely beefy mechanical hard drives have a certain charm that SSDs will never have.
But that constraint always really pushed people toward finding pure mechanical solutions to problems that in the real world would just be solved by slapping on another servo. One of my favourite examples was a single-motor steered castor, where a ratcheting mechanism switched between wheel driving and castor rotation based on which way you ran the motor.
I think another factor with it is just that LEGO makes the pursuit of a mechanism-type solution inexpensive, effortless, and fun, whereas in "real" industrial automation, every new gear or bearing is another point of failure, one more thing requiring lubrication check-ups and so on.
Now it's just a secondary storage drive that filled up pretty quickly. It felt good to say, "I'm running a 10K raptor."
It’s incredibly nostalgic.
Fortunately, that machine supported diskless operations, which was painfully slow, but ... that machine was painfully slow anyway (by 2005 standards), and it was part of what I liked about it.
Years later, I ran into a CAD workstation with a 10k RPM disk drive, and the noise was just ridiculous. I was so certain it had to be a fan until my coworker replaced the disk drive, I felt rather sheepish afterwards.
I sometimes miss good old HDDs, because you could tell if they were busy just by listening. But considering the godawful noise the really fast HDDs made, SSDs are a blessing.
I used to run my HDDs in soundproofed enclosures (a company was selling those back in the days) but of course it would make them overheat. So I'd cut a square hole in the HDD enclosure (and through the soundproofing foam inside the enclosure) and then I'd put a large but quiet fan on top of the HDD. This worked great, for years.
Having owned silent computers like the Commodore C64 / C128 and Amiga the switch to the early ultra noisy PC was particularly painful to me. So back when "silent PCs" weren't a thing I made my own: I'd run fans at 7 V instead of 12 (by using the 12 V and 5 V pins to create 7 V), I had my neighbor (electrical engineer) create me a device I'd put into all my PSUs that'd turn the PSU's fan off when the heat wasn't too high (back then this didn't exist: but I wanted one anyway so I had my neighbor "invent" one and I'd then replicate it in all my PSUs) and... When I found these HDD "quietening" enclosures, I ordered so many the company asked me if I wanted to become the official importer for the Benelux area : )
I'd have super quiet "panaflo" fans shipped to me from Japan and I'd replace all my PSU / CPU / tower fans with these quiet fans.
So basically I had quiet PCs before it was a thing.
Nowadays I just buy Be Quiet! PSUs / fans and a well insulated tower and I'm a happy camper. Things got way quieter : )
HDD: sssrrrrrrrr clankclankclank ssssrrrr
PC-Speaker when pressing too many keys: MEEEEP
Modem: booooob, boop beep boop beep boop boop bli blu bri bru brrriiiiii BWANG BWANG BWANG KCHHHHHHHHH
It sounded like a turbine was ramping up! :D
starting up a big lathe or mill spindle, or maybe a large phase converter with a heavy lever switch come close, but they don't scratch that "i'm in a super computer lab" itch as much as the fantastic whir of a raptor RAID.
utilitarian feature : you could hear a bad sector from anywhere in a large room.
The 15K rpm drives could sometimes be quite noisy; especially with 48 or more in an array.
Three of the engineers with whom I worked specialised in disk failure analysis; one of their tools was an inductive telephone earpiece pickup coil with suction cup, connected to a small amplified speaker. These guys would put the pickup on top of a drive and listen to all the electronics, spindle motor and head-moving voice coil electromagnetic noise as the drive spun up. This process would generally be followed by comments such as: "Hmm, head 4 sounds iffy", "This unit's on older firmware" and "Sounds like the heads aren't coming off the ramp"...
A lost/fading talent now that 2 out of 3 are retired". It was quite amazing to watch and listen to these guys at work.
but on the note of hearing differences in sounds, back in the day of dial up, since my ISP gave unlimited free dial up minutes, but it had to last no more than 2 hours (it would auto kick you off if you were on for more than 2) my modem would dial every 2 hours... And it got to a stage that I could know, by sound, if it was going to get a 56k link or a 33.6k link...
Ah, yes, the Mark I Real-Time Fourier Analyzer.
Though half an hour of clips is a bit excessive.
it would heat the whole case it was mounted in and make enough noise to be heard rooms away... but it was fast! and two gigabytes was enough for not just one but mulitple linux partitions alongside windows and os/2.
i remember a friend's father losing his shit when i told him i had such a large disk. because it was built for the datacenter, i had to use an external desk fan to cool it. it was simultaneously completely impractical and totally awesome.
ed: there's the beast. shocked you can still buy it! forgot it was scsi (which also made it even faster because the good adaptec scsi adapters of the day offloaded i/o interrupts from the main cpu)! https://www.priceblaze.com/st12550n.html?ref=gshp&msclkid=e8...
It was obsolete by the time I had gotten my hands on it but I remember being so damn surprised by how loud/hot it was to get it working in one of my legacy systems. It was my first experience as a kiddo with datacenter-esque hardware + SCSI. I think I got Slackware installed on it and then just gave up on it subconsciously due to how much of a PIA it was...
Thanks for sharing that link... wouldn't have realized it was the same drive as my nostalgia-blast if not for the pics. That Barracuda sticker was badass.
ST - seagate technologies
1 - 3.5" full height
2550 - unformatted capacity
N - fast scsi
if i recall, this scheme went all the way back to the early 80s.
First port of call was a chkdsk, of course - and one of the drives had some bad sectors. It happens. I threw it in the bin, and reinstalled Windows on the other one, which was fine. Mmm... it was so fast! That's what you get from those extra GHz and MBs, of course. 4 years is a long time in computer performance terms.
After about a year of very enjoyable super fast PC use, the hard drive died. I replaced it with some generic UDMA IDE thing - and discovered almost immediately how much the 10,000 RPM SCSI drive had been bringing to the table :/
All my other old HDDs are still here in spirit, stripped of their powerful magnets now decorating my fridge.
I heard about a hack I never tried, myself, where you buy an oversized hard drive and only use the beginning of it. Hard drives store data from the outside in, so you can improve latency by minimizing arm travel, and improve throughput by storing data where the linear velocity is faster. No idea how big of a difference this would make.
However, latency is about both the latency of the arm movement and the rotational latency. The latter you can't overcome by short-stroking.
However, short-stroking does point to an interesting problem when hard drives were still relevant.
If you didn't size your storage right, you ran out of IOPs long before you ran out of capacity.
For instance, if you run VMs on your SAN / storage array, you may have to stop putting VMs on the storage long before capacity is reached.
It's actually kind of funny that "just using the beginning 25%" of the drive is completely unnecessary provided you've got your partitions set up properly- you just create a partition at the beginning of the disk that has the data you want to access the quickest, and use the end of the disk for data that you don't access coincident with the data you want to get the fastest (a perfect place to put a dual-booted Linux install, for instance).
Meanwhile I still find laptops from the ~2015 era that for some reason shipped with a HDD. I remember the Macbook Air being one of the first computers to make a SSD standard while the rest of the laptop/'netbook' was for some reason surprised that it was so much faster. :/
I still love hard drives for bulk storage but I will never use a HDD based machine... especially not if it is running Windows >=8. If only EC2/cloud providers would make IOPs cheaper - for some reason they seem to be crazy expensive compared to what a $50 SSD can give.
Their IOPs and latency was even better.
I find it hard to believe spinning an electric motor and a relatively light and small disc that fast is much of a challenge to keep together, especially in such a coddled environment.
Even back in the early 90s my RC10 had a 38k rpm "modified" motor; the Motown Missile. That thing lived through hell...
Hard drives have slightly higher longevity requirements.
When the engines did run closer to 20,000 they were indeed rebuilt much more often. I am not well versed in F1 regulation history but Wikipedia claims that before 2005 engines were not required to last for two race weekends, meaning you could rebuild the engine between each race weekend if you wanted to. At that time there was no RPM limit for the engines and the iconic Ferrari F2004 supposedly maxed out at 19,000 RPM.
So maybe the comment you are replying to is referring to pre-2005 F1 engines :) I have no idea myself if a modern F1 engine could run at 20,000 and still be as durable as the current engines or if running at such high RPM inherently means bad durability.
In the past the rules were different.
Even if what you said were true, so what?
We're talking about a tiny spinning disc on a brushless hub motor. There's basically a single moving part, maybe a few more if riding on ball bearings.
Do you have any understanding of what is going on inside a many-cylinder internal combustion piston engine spinning at 20k rpm? We can view the flywheel as the hard disk platter equivalent, the real madness is at the reciprocating mass being flung back and forth at the same rate.
Edit: Here's another useful reference point to help put RPM numbers into perspective: a turbocharger's rotating assembly spins on the order of 200-300k RPM without flying apart. A minute is a pretty long time.
This precision structure has to be maintained at 10k RPM. Can it be maintained at 20k RPM? Maybe not so easily. Let's not undersell the technology.
"Part of the problem is keeping the platters together at those speeds"
I'm not speaking to seeking or precision at all, only pointing out there's not really any challenge in keeping the platters together at these speeds.
CBR250rr to 20, and those were actually street legal, and there are still a lot of them on the roads.
The key to speed is having lots of drives, RAM and SSD write cache.
I plan on getting the new TrueNAS Mini XL this year with 8x14TB.
Basically, WD decided if was cheaper to just make 7200 drives and sell some mislabeled as a '5400 class' drive.
3x Firecuda 4tb NVME
2x QVO 8tb SATA SSD
4x WD Ultrastar 18tb.
My use case is I need tons of storage that operates fast and is used for all sorts of things (creative work, gaming, archiving, job processing), sometimes all at the same time. It's a threadripper pro workstation pc, so I have spare PCIE slots to upgrade later.
I'm thinking of replacing a couple of the QVO SSDs with Ultrastars and using a couple of the FireCudas as cache drives for the platter drives. Good idea or bad idea? Would I be making a meaningful tradeoff or should I just go for the extra space?
If you are talking about local storage for a workstation then I am not sure. Depends on your workflow. If you have a "work on this on the fast stuff, then when I am done I can move it to the spinning rust" then you might want to figure out largest project size for fast vs long term storage of the projects.
Sorry if this is not helpful.
it was on bryan's youtube only
They did do a later generation that could do 15k RPM but by then SSD's were starting to become trusted and more palatable price wise, though I dare an SSD of that ere to work near on 24/7 for ten years solid abuse.
Still wish I had pushed back!
They were insanely reliable/performant drives and after reading enough reviews I couldn't resist back in the day. Regarding benchmarks, they definitely had a bit more pep by the numbers.
My two 10k WD RPM's ended up in a redundant RAID in my Sun W2100z. They ran over a decade with 24/7 use as a Debian/Ubuntu OS LVM.
I'm a bit surprised that it's slower than a car.
