It never ceases to amaze me how far we can still take a piece of technology that was invented in the 50s.
That’s like developing punch cards to the point where the holes are microscopic and can also store terabytes of data. It’s almost Steampunk-y.
More like microscopic fidget bubble poppers.
When the computer wants a bit to be a 1, it pops it down. When it wants it to be a 0, it pops it up.
If it were like a punch card, it couldn’t be rewritten as writing to it would permanently damage the disc. A CD-RW is basically a microscopic punch card though, because the laser actually burns away material to write the data to the CD.
They work through electron tunneling through a semiconductor, so something does go through them like an old punch card reader
Talking about steam, steam-powered things are 2 thousand years old at least and we still use the technology when we crack atoms to make energy.
What the Romans had wasn’t comparable with an industrial steam engine. The working principle of steam pushing against a cylinder was similar, but they lacked the tools and metallurgy to build a steam cauldron that could be pressurized, so their steam engine could only do parlor tricks like opening a temple door once, and not perform real continuous work.
That’s how most technology is:
- combustion engines - early 1900s, earlier if you count steam engines
- missiles - 13th century China, gunpowder was much earlier
- wind energy - windmills appeared in the 9th century, potentially as early as the 4th
Almost everything we have today is due to incremental improvements from something much older.
This isn’t unique to computing.
Just about all of the products and technology we see are the results of generations of innovations and improvements.
Look at the automobile, for example. It’s really shaped my view of the significance of new industries; we could be stuck with them for the rest of human history.
Seagate. The company that sold me an HDD which broke down two days after the warranty expired.
No thanks.
laughing in Western Digital HDD running for about 10 years now
I had the opposite experience. My Seagates have been running for over a decade now. The one time I went with Western Digital, both drives crapped out in a few years.
Funny because I have a box of Seagate consumer drives recovered from systems going to recycling that just won’t quit. And my experience with WD drives is the same as your experience with Seagate.
Edit: now that I think about it, my WD experience is from many years ago. But the Seagate drives I have are not new either.
Survivorship bias. Obviously the ones that survived their users long enough to go to recycling would last longer than those that crap out right away and need to be replaced before the end of the life of the whole system.
I mean, obviously the whole thing is biased, if objective stats state that neither is particularly more prone to failure than the other, it’s just people who used a different brand once and had it fail. Which happens sometimes.
Had the same experience and opinion for years, they do fine on Backblaze’s drive stats but don’t know that I’ll ever super trust them just 'cus.
That said, the current home server has a mix of drives from different manufacturers including seagate to hopefully mitigate the chances that more than one fails at a time.
I currently have an 8 year old Seagate external 4TB drive. Should I be concerned?
Any 8 years old hard drive is a concern. Don’t get sucked into thinking Seagate is a bad brand because of anecdotal evidence. He might’ve bought a Seagate hard drive with manufacturing defect, but actual data don’t really show any particular brand with worse reliability, IIRC. What you should do is research whether the particular model of your drive is known to have reliability problems or not. That’s a better indicator than the brand.
I can’t wait for datacenters to decommission these so I can actually afford an array of them on the second-hand market.
Way ahead of you… I have a Brocade ICX6650 waiting to be racked up once I’m not limited to just the single 15A circuit my rack runs off of currently 😅
Hopefully 40G interconnect between it and the main switch everything using now will be enough for the storage nodes and the storage network/VLAN.
Exactly, my nas is currently made up of decommissioned 18tb exos. Great deal and I can usually still get them rma’d the handful of times they fail
Serverpartdeals has done me well, drives often come new enough that they still have a decent amount of manufacturers warranty remaining (exos is 5yr) and depending on the drive you buy from them spd will rma a drive for 5 years from purchase (but not always, depends on the listing, read the fine print).
I have gotten 2 bad drives from them out of 18 over 5 years or so. Both bad drives were found almost immediately with basic maintenance steps prior to adding to the array (zeroing out the drives, badblocks) and both were rma’d by seagate within 3-5 days because they were still within the mfr warranty.
If you’re running a gigantic raid array like me (288tb and counting!) it would be wise to recognize that rotational hard drives are doomed and you need a robust backup solution that can handle gigantic amounts of data long term. I have a tape drive for that because I got it cheap at an electronics recycler sold as not working (thankfully it was an easy fix) but this is typically a super expensive route. If you only have like 20tb then you can look into stuff like cloud services, bluray, redundant hard drive, etc. or do like I did in the beginning and just accept that your pirated anime collection might go poof one day lol
30/32 = 0.938
That’s less than a single terabyte. I have a microSD card bigger than that!
;)
Now now, no self-shaming about the size of your card. It’s how you use it!
Great, can’t wait to afford one in 2050.
