Is this SSD dead?

I've been using it for CCTV recording as a primary fast disk.

Is it about to die if at 1%?

I set it up a few years ago, I remember reading that it was advised to have initial recordings go to a fast disk like an SSD, then to have it copy across to another drive. Hmmm....
 
Also I think maybe for noise, as it's probably quieter to have it writing to an SSD first, then copy the files across every half hour?

I do have an 18TB Seagate Exos for long term storage.

Not sure what Wear Leveling Count means in this context.

So far as I can gather, your drive is otherwise healthy. It has not used any reserved blocks and it is not struggling to recover data written to the drive (ECC errors).

That confused me too, I wasn't sure what it meant.

There's definitely issues with the PC though, which is why I started investigating. Hardly any of the cams are recording reliably at the moment, if at all.

I've tried shifting all recording directly to the 18TB Exos instead to see if that helps.

I usually connect to it over remote desktop as the tower is in the attic, and it's been quite unreliable to connect, and navigating windows has been super slow and dodgy. Had to do quite a lot of hard reboots the last week to get it back online (plus sort out some stupid windows updates, and get rid of all the copilot crap that loaded)

I've resulted to trying to delete the entire stored folder to completely clear all the data, so Blue Iris can start fresh. Explorer kept crashing though, so I ran a command line command to try and delete the 40k recording files more reliably. It's been running for over an hour now and is down to 15k files left :eek:

It doesn't get super full (or rather it shouldn't as per the BI settings), but it is constantly being written to as I have the cams set to continuous 24/7 recording.

There have been a handful of cases where it's frozen in the past and gotten to a very low level when I remote in, so I manually clear out the 'new' folder because for some reason not everything has been transferred to the 'stored' folder on the 18TB disk. I presume due to some kind of bug.

The 18TB disk is set to only fill to about 90% capacity before deleting old files (but occasionally also maxes out, maybe a couple of times a year, where I manually delete some files)

That's an impressive amount of data written

Why not have it only record motion?
Instead of 24/7 recording?

I've been bitten too many times when using old ring cameras where the motion wasn't reliable, then I got used to the 24/7 recording with Nest.

Now that I have all IP cams and everything gets recorded locally I prefer to have all cams recording 24/7 in 4k on a massive hard drive so I get the full picture of anything that might be happening at any given time in case I need to check something that for some reason the motion didn't trigger on.

You bought Samsung 850 EVO for CCTV? :eek::o:cry:

Unfortunately you bought the wrong SSD for CCTV, 250GB Samsung 850 EVO rated 75TBW was not suitable for CCTV. You should bought 500GB WD Red SA500 SATA SSD rated for 2500TBW that are suitable for 24/7 operations like CCTV but OCUK do not stock it, you can order it somewhere.

lol, I don’t think I actually bought it specifically, I think I just had it lying around :D

Got a link to manufacturer page for the SA500?

A quick google on mobile and I only see one rated for 350TBW, not 2,500?
 
Ahh, that makes sense, thanks.

Looking at the spec for the Samsung 870 evo, the TBW seems pretty close for for the 1TB, and less for the 2TB and 4TB.

* Warrantied TBW for 870 EVO: 150 TBW for 250 GB model, 300 TBW for 500 GB model, 600 TBW for 1 TB model, 1,200 TBW for 2 TB model and 2,400 TBW for 4 TB model
