    I’m going to remind you that these fuckers are LOUD, like ROARING LOUD, so might not be suitable for your living room server.

    OK…what’s this HAMR technology and how does it play compared to the typical CMR/SMR performance differences?

      Heat-Assisted Magnetic Recording. It uses a laser to heat the drive platter, allowing for higher areal density and increased capacity.

      I am ignorant on the CMR/SMR differences in performance

        I fear HAMR sounds like a variation on the idea of getting a coarser method to prepare the data to be written, just like on SMR. These kind of hard drives are good for slow predictable sequential storage, but they suck at writing more randomly. They’re good for surveillance storage and things like that, but no good for daily use in a computer.

          My poor memory is telling me the heat is used to make the bits easier to flip, so you can use a weaker magnetic field that only affects a smaller area, allowing you to pack in bits more closely. It shouldn’t have the same problem as SMR.

        I mean, newer server-grade models with independent actuators can easily saturate a SATA 3 connection. As far as speeds go, a raid-5 or raid-6 setup or equivalent should be pretty damn fast, especially if they start rolling out those independent actuators into the consumer market.

        As far as latency goes? Yeah, you should stick to solid state…but this breathes new life into the HDD market for sure.

      The speed usually increases with capacity, but this drive uses HAMR instead of CMR, so it will be interesting to see what effect that has on the speed. The fastest HDDs available now can max out SATA 3 on sequential transfers, but they use dual actuators.

        I’ve bought 2 Seagate drives and both have failed. Meanwhile, I still have my 2 15yo WD drives working.

        I hope I didn’t just jinx myself. Lol

          I’ve got the opposite experience, with WD.

          You know who uses loads of Seagate drives? Backblaze. They also publish the stats. They wouldn’t be buying Seagate drives if they were significantly worse than the others.

          The important thing is to back up your shit. All drives fail.

          I get it, I’ve had the opposite experience with wd, but they were 2.5” portable drives. All my desktop stuff works perfectly still 🤞

        I bought a seagate. Brand new. 250gb, back when 250gb on one hard drive cost a fuckton.

        It sat in a box until I was done burning the files on my old 60gb hard drive onto dvd-r’s.

        Finally, like 2 months later, I open the box. Install the drive. Put all the files from dvds onto the hard drive.

        And after I finished, 2 weeks later it totally dies. Outside of return window, but within the warranty period. Seagate refused to honor their warranty even though I still had the reciept.

        That was like 2005. Western Digital has now gotten my business ever since. Multiple drives bought. Not because the drives die, but because datawise I outgrow them. My current setup is 18TB and a 12TB. I figure by 2027 I’ll need to update that 12TB to a 30TB. Which I assume will still cost $400 at that point.

        Return customer? No no. We’ll hassle our customer and send bad vibes. Make him frustrated for ever shopping our brznd! Gotta protect that one time $400 purchase! It’s totally worth losing 20 years of sales!

          As @renegadespork@lemmy.jelliefrontier.net said, infant mortality is a concern with spinning disks, if I recall (been out of reliability for a few years) things like bearings are super sensitive to handling and storage, vibrations and the like can totally cause microscopic damage causing premature failure, once they’re good though they’re good until they wear out. A lot of electronics follow that or the infant mortality curve, stuff dying out of the box sucks, but it’s not unexpected from a reliability POV.

          Shitty of Seagate not to honour the warranty, that’d turn me off as well. Mine is pettier, when I was building my nas/server I initially bought some WD reds, returned those and went for some Seagate ironwolf drives because the reds made this really irritating whine you could hear across the room, at the time we had a single room apartment so was no good.

          I’ve had a lot of seagates simply because they’re the cheapest crap on the market and my budget was low. But unfortunately, crap is what you get.
