What's next, PCB producers?
Doubt it. Those don’t require as crazy of infrastructure as microchips. If PCB starts going up, we’re in huge trouble |

nowadays RAID is done with software, on linux if possible. common choices are ZFS and md-raid. you connect drives with SATA or SAS to a computer, and you can add them to a pool. drives added to pool will be formatted once. hardware raid is discouraged, because if the RAID card fails you need a replacement of the exact same kind, with same firmware version, and they can have other difficulties t...
That's great, I'd love to not have to buy one of those machines, and I have been running my JF on a laptop just running Linux with a single one of the 16tb drives. If the drives added to the pool need to be formatted, is there a possibility that it wipes the data on it? I'll take a bit of time to read up on some of the options you mentioned. Thanks for the help! |

that's what I meant, yes, but you said you have 2 16 TB drives right? at least with ZFS, setting up a mirror can be done only starting with a single drive. It's a godsend. first, you take the empty drive, check that it's actually empty, and if so, create a ZFS pool of a single drive from it, with zpool create. copy all your data over. you can use rsync, it has a bunch of options for preserving most filesystem metadata, and for printing progress. when done, check that absolutely everything got transferred, and add the other 16 TB drive too to the pool with zpool attach. doing this will convert the pool with only a disk vdev, into a pool with a mirror vdev of 2 disks. further recommended reading: https://openzfs.github.io/openzfs-docs/man/master/8/zpool.8.html you may want to enable compression from the beginning. if you do it later, existing data won't be compressed. media files mostly don't benefit from this. compression is enabled on the dataset level, with the zfs command, if you set it to lz4 (recommended alg) for the root dataset, everything will be compressed that way. |

also, when and where did you buy those 16 TB drives? I badly need a few like those |

Their prices seem 2x what they were a few years ago. 2.5 years ago I bought two 16TB HGSTs from them for $170 each. |

3 months ago, watching ram prices skyrocketing, anticipating this exact scenario would happen, i bought 5 10tb drives. best decision i've made in a while.
I ordered a couple of NAS drives during the holiday specials thinking the same thing. Received a confirmation email saying they would ship in a few days. 4 weeks passed without a single peep from WD. Started to get nervous my order would be cancelled. Then first week of January I got an email saying they were backordered but should be fulfilled "soon". Didn't get my drives till end of January but well worth the wait. |

Bought a bunch of 20s a while back. My only concern now is if (when) one of them dies, I might not be able to get the same one (or any at all). |

That's retirement money right there. |

Getting a half dozen 24tb nas drives this morning was painful. They are twice the cost of last fall and most vendors, even big ones, only had one or two available. This is insanity. |

This feels like such a beginner question to be asking on Lemmy, let alone the tech community, but how does one go about setting up a RAID array to have my data mirrored? I only know the basics I remember about raid 1 and raid 0. Is this RAID array something you can do without one of those "multi-hard drive units"? I have 2 16TB hard drives that I'd like to have one as a mirror copy of the first...
TrueNAS is a easy way to start |

Oh this is perfect, thanks so much! I've got one of the hard drives in use but I could definitely wipe the other one to make a proper copy with the zpool. Thanks for giving me a fun little week task! |

Was looking at NVMEs, only $1500 for a small no name Gen 3 with 3gbps max transfer rate. Some newer and faster name brand drives were listed as $400-500, but they were also out of stock, so those prices probably weren't accurate. |

I really hope this is a temporary supply bottleneck. I understand the constraints of producing chips and highly specialized hardware but AI demand is only going to go up from here. I'm optimistic a game changer gets whipped out of thin air
It's not really going up.... I got bored with it last year, and have turned off everything but search summaries, as they often just put the answer right up front, no click throughs. Also I use a voice aid to set timers, reminders, and alarms.... And this seems to be a common story lately. I can't see AI really exploding beyond basic uses like that. Some people are still inovating and playing with AI, but it'll settle down. |

Same with RAM. Unfortunately, the RAM shortage is caused by a RAM component being diverted to specialized packages that can't easily be converted into normal RAM. So even a bubble bursting won't bring RAM onto the market.
And those hard drives will almost certainly be shredded. |

It depends greatly on what kind of machine you are running. Many PC's have RAID capabilities built into their BIOS. Others will need special RAID software, which will vary by OS. Finally you can buy the multidisk raid enclosures, which may either have their own raid capabilities on the hardware or may use a software solution to go with the hardware. |

Why would they? It's by far their biggest market. This is capitalism working as designed: sell to the companies running datacenters, then you and they can make money by renting computing resources at a premium to the peasants, and by spying on those peasants as they use it.
Yes I know their reasons. I want them to not have the choice |

I recently had a drive fail in my 4 bay nas. Amusingly, synology branded drives seem like they're pretty close to p ice parity with OE drives these days. |

Why would they? I don't see how they'd have to work more than in regular server farms... I could be wrong though. |

It's data privacy. It's cheaper to shred them than pay someone to dban them. |

Oh, you mean actual shredding! Thought that was some IT lingo for an HDD that is well past its prime, lol. |
