Same here.
Yes, well and truly down. The disk corrupted at 01:50, rebooted and couldn't load the database.
It's okay at the moment after a restart but I am going to take the server down in a while and recover to a new disk.

I'll mirror it as soon as another disk I just ordered arrives. A few more changes to come yet over the week but downtime shouldn't be too long (famous last words :wry: )

[Totally off Topic]
You have highlighted the concerns I still have with SSD's.
They are wonderful but if you are constantly writing/re-writing the possibility of exceeding the wear limits is possible in 10's of months not years.
I know I am now going to get 'hit' by the maths Arrgh !!! ;D

Intel is my preferred choice.

Samsung is also good and getting better. But still concerned though 😃

What make of ssd was it?
Intel is my preferred choice.
Liteon - cost £250 (+VAT) odd to replace so didn't!
It lasted 4 months.... (it came with the machine)
Problem is that with at least one (actually more like 6) write per second, it never gets a chance to use its wear levelling software - they say to leave it quiet for 6 hours every so often!

See this one I have been following: http://www.kitguru.net/components/ssd-drives/zardon/ocz-challenge-kitguru-to-kill-5x-arc-100-ssd-drives/ (http://www.kitguru.net/components/ssd-drives/zardon/ocz-challenge-kitguru-to-kill-5x-arc-100-ssd-drives/)
Also very interesting.
tbailey2,
Could have use a mirrored pair of SSD's that you could drop one of the pairs out of, at regular intervals to 'Wear level', alternating the SSD each time.

Interesting challenge on the OCZ ARC 100, first died at 322TB of data written, the last was still going at well over 500TB by the looks of it, last update I can find was 19th March, surely it's died by now!

if you really want to use an ssd tho then get a 3d nand MLC model. (samsung 850 pro)

yeah you should be using an hdd for this.

It's been on a spinning WD red drive since that day as already noted (http://forum.kitz.co.uk/index.php/topic,15248.msg283477.html#msg283477). I have a NAS here with five in and that's been running for over 3 years.....

No still going as far as I can tell. There is a competition running to guess the final ssd's point of Failure.
Not any more, it died today at 695.5TB (http://www.kitguru.net/components/ssd-drives/zardon/ocz-competition-winner-final-arc-100-hits-695-5tb/) unless of course it's an April's fool!

Just like any other storage media always have a backup/image before it meets it's maker ;)
Post by: AArdvark on April 01, 2015, 09:23:32 PM
Still blindingly good for a ssd rated at 22TB.

Absolutely, I have Raid 6, cloud and off site USB HDD backup of really important stuff.

Yes, it very impressive and perhaps I might try one in laptop at work now.Just like any other storage media always have a backup/image before it meets it's maker ;)

Likewise although I use a known data centre rather than out-there-somewhere cloud which has a habit of vanishing when you most need it...
Here there are two x RAID 5 NAS one backing up the other and physically separated, mirrored drives on the main machines, plus separate external USB drives for scheduled daily disk image backups. And the MDWS tables and other database material are also written live to duplicated databases at a London data centre.
