  • Having a RAID array would make OP’s question somewhat moot - because a drive failure would be less significant.

    You and others are focusing on addressing the likelihood of the risk. I’m saying it would be better to address the severity instead. The comment is relevant, just slightly more abstract, but very much on topic.

    You’re right that motherboard RAID is worse than OS RAID. I just wasn’t sure what OP’s backup device actually is, if it’s a PC or some simple bespoke NAS box. But it’s more Hardware Controller > OS > Motherboard, generally speaking.



  • Depends how much storage you’re looking to get. https://diskprices.com/

    Looking at new only, you can get a 3TB drive for $36 on Amazon. 3 of those for $108, 6TB storage with n-1 redundancy. Add $36 for 3TB as many times as your controller will allow (or 4, that’s all they have in stock lol).

    diskprices.com also has variants for European and other Amazon. Or you could check other retailers. Also the “used” drives are very cheap - these are typically refurbished datacentre drives. They’ll have a shorter lifespan, but that’s still probably better than a single drive with no redundancy.

    This kind of thing is worth spending money on. Otherwise your backup solution isn’t really a good backup solution, if you’re worried about it failing.

    Edit: Also it isn’t complicated to set up at all. RAID 5 has slightly more setup, but RAID 1, 0 & 10 are widely available natively in most motherboards, and have been for decades. If you’re already setting up some external backup device, it really isn’t much extra, for a good payoff.



  • Why aren’t you running your drives in a RAID array? RAID 5 is n-1, meaning you get n-1 total storage space and can withstand any 1 drive failing. You do need at least 3 drives, but that’s what you should be doing - not just running a manual mirror backup or whatever. You also get the speed advantage from striping data across the drives (although this speed is nothing to an SSD).

    If you really want to be serious about backing up then it’s 3,2,1 - 3 copies, on 2 different types of media, with 1 in an off-site location. As a minimum.

    But first off I think you should upgrade your long-term backup to have some kind of RAID array. With 2 drives you can do RAID 10 (RAID 0 and RAID 1 combined), you’ll only get the storage of 1 drive but you’ll have one to one redundancy and striping. With 3 or more drives do RAID 5 so you’ll have more storage (eg 3x 8GB drives would give 16GB, 4x 8GB would be 24GB, etc), striping for speed, and also the same n-1 redundancy.

    You may need a PCIe card for RAID 5, not all motherboards support it natively. You should be able to find a decent one for not too much, if you look around. RAID 1 and 0 (and maybe 10) often are supported natively.





  • It’s a bit more nuanced. If you’re in North America, it’s more likely than not that you’ll have a Californian tomato. If you’re in Asia, it’s probably Chinese. If you’re in Europe there’s a lot of clout for Italian tomatoes, but you’ll probably see a lot of local produce front and centre, with maybe some budget options from another country or in the off-season.

    But ultimately water shortages in Cali are going to have little effect on Europe. Prices on the shelve are so far removed beyond cost that a global market price rise caused by the shortage won’t have a massive effect on the price consumers pay - we’re already paying as much as they can get away with charging, at this point it doesn’t really matter much what excuse they use to raise the price because they were already planning to do that anyway.
