But how many waste their time doing that ? I certainly don't, I just decide that a new drive is so cheap that it isn't worth my time.
And I record to the one drive and just shift stuff off to a much bigger external drive when there isn't enough space on the drive I record to for the evening's recording.
I have had a couple of the external hard drives die.
They ALWAYS have wear levelling applied
Wear levelling doesn't work like that.
Yes it does. If the user uses it like that, with most of the drive filled with stuff hardly ever replaced, no wear levelling can do anything about the problem that only a tiny subset of the drive is repeatedly used.
But how many people just record so much crap and haven't got the time to watch it.
I use my PVR to record a limited number of programs and/or to timeshift to be able to skip adverts.
I may record a series but delete when watched, or find that after watching one episode that the rest is not worth the recording space and deleted immediately. my 1Tbyte HDD is never more than 30% full.
HDDs are funny things. Some go on & on & on, some don't. The oldest I have in service is just 60G - it'll get replaced when something needs doing, it's still going ok. Meanwhile 1&2T HDDs have failed.
We tend to keep some series and films to watch again - possibly some years down the line.
Yes, we often delete series because the first episode really tuns us off.
Our 2TB HDD has only 16% free. I must move some over to the home server, which has much more space available.

Thats what I do. And it isnt necessarily a silly thing to do. Our free to air broadcast TV in our summer has a real death of stuff that I choose to watch so in theory I can go back over what I didn't get around to watching in the previous year when I need something to watch.
In reality I never do end up watching everything I have recorded and I can't be bothered cleaning up the drive when it is so cheap to buy another when I need more space.
I record everything, only ever watch the election eve vote count live so I can watch it when it suits me and not when it is broadcast and so I can skip the ads, even on the govt channels we have. One of them has normal commercial ads and the other has ads for its own material they will broadcast.
I normally do, but not always with the best stuff. I hardly ever watch anything more than once but do with the best stuff like Foyles War and 7 Up etc.
I don't waste my time furiously cleaning up the drives that I have recorded broadcast TV on. I have more than a dozen
1-3TB drives and a 20TB external drive, the latest drive.
Some appear to wear our. Without having read this story, I don't think I would have bought those drives, from first principles. You'd have to be desperate to buy these, if you were at BackBlaze. The Seagate salesman would have told them that.
Years ago, they tried to synchronize the spindles of the drives, with a cable from drive to drive. That was on SCSI drives. But I don't think that was a success, because they seemed to stop doing that.
Another question would be "how much damping does a drive require". I don't know the answer to that. Like, if you mount a drive on those silicon rubber bumpers, is that a good thing to do or a stupid thing ? Dunno. Some of the drives feature a subsonic "thump" on long seeks.

All the USB3 enclosures that I have seen have a different connector so you should be able to tell, if this is the standard -
Hah, I should have just looked at the enclosures, where it's marked what they are. The connections are mostly USB 3.1 Gen 1, with a couple of USB 3.0.
USB 3.1 Gen 1 being "USB 3.0 in disguise" :-)
Thanks to usb.org , those are the same thing.

Well - howls of derisive laughter.
To the OP.... Hows that list of drive makes and models coming along? :-)
S.
Indeed. I've been unwell the last few days. Today should be OK.
The report is some 900 lines long. You want it posted here?
There are 3 1TB drives, with no replaced sectors. There's 1 3TB drive, same. There's one 2TB drive which reports >400 DMA CRC errors, but DriveDx opines that this is probably the interface card/cable rather than the drive itself. There was another 1TB drive, but that reports 14 replaced sectors, so I've removed that one from consideration and will take it to the tip.
OK, whats the make and model and form factor size of the 5 remaining drives?

right you have:
2 off Toshiba HDWD110 1TB Sata 3.0 3.5 inch drives 1 off Toshiba DT01ACA100 1TB Sata 3.0 3.5 inch drive 1 off Toshiba DT01ACA300 3TB Sata 3.0 3.5 inch drive 1 off Seagate ST2000DM008 2TB Sata 3.1 3.5 inch drive.Some of these were operating in Sata 2.0 mode rather than its SATA 3.0 mode, I can only assume this was because you were connecting to them via USB rather than via SATA or to a SATA 2.0 port rather than a SATA 3.0 port.
So thats a total storage space of 8TB across 5 drives......
I've now taken the rest of this conversation into anemail to you assuming your email address is correct....
Don't do what one ebayer seller did to me a couple of months ago, wrap a
4TB drive in cling film (no anti static bag!) and then put into a jiffy bag instead of proper polystyrene packaging and a cardboard box.The Postal worker dutifully passed the package through the letter box, to drop 4 ft straight onto a concrete floor.
The hard drive was FUBAR upon impact with said floor and I got a refund from the ebay seller after some persistence as the seller had absolutely no idea on how to ship a hard drive safely and I had to explain to him how drives should be shipped and how easily damaged they are!
I once had 2 sticks of RAM sent to me wrapped in cling film instead of in antistatic packaging via Ebay... it consequently failed MemTest86! Cue another refund from another clueless seller.
However, SSDs reserve a proportion of their storage cells for wear levelling and replacement of bad cells. These reserved cells are not visible to the operating system. Drives with higher write endurance specifications will generally have more hidden cells. Also, the drive can move data around without the operating system being aware.
