I am sure I have mentioned this before but can't find the previous thread; maybe it was on the other forum?

Anyway it is worth warning again about failed or aborted models not always deleting themselves from your hard drive.

I run BOINC on my C:\ SSD to save continuous running of my other hard drives and also because the models run a little quicker. It is only 64GB in size and more than half of that is used by the Windows 7 OS and other essential files. I have just noticed that BOINC was reporting it couldn't run one of the new models because there wasn't enough disk space.

Looking in the Program data -> BOINC -> projects -> ClimatePrediction.net folder there were several folders and zip files with with old modified dates and several zip files all starting with 'hadam' or 'hadcm'. None of the names referred to models currently running so I have recycled them and released over 3GB of space.

Some of these are probably failed or aborted models affected by the many power cuts we have had this winter.

I ran boinc on the ssd in my netbook and now the ssd seems to be broken. I understand they are not designed for the number of write cycles boinc subjects them to, unless they have improved since the early type I had?

I run BOINC on my D:\ SSD for 21 month.

Host writes 243 Terabytes on INTEL 330 SSD.

Media wearout indicator is 85.

Carpe diem,

Well,I am no hardware expert so don't know how to measure the wear on my Crucial SSD but I do know I have been running BOINC on it since October 2010. It had a capacity of just over 64GB then and still has the same now and I have noticed no deterioration in its performance. It has no bad sectors which is not the case for the main mechanical drive on this computer.

Crucial sell these as replacements for the C: drive and claim their average time to failure is greater than that for a mechanical drive. I have no reason to doubt this and I am considering purchasing a much bigger one in the near future.

Media wearout indicator is shown with software like Argus monitor or INTEL SSD Toolbox.

May be coincidence then, I haven't been using the netbook for much apart from boinc so maybe it is worth trying again, making sure I get the crucial brand? The way I had the disk partitioned Boinc only had about 10GB to play in. If I do it again I will give it rather more.

Using Boinc isn't average usage. The number of write operations is limited on an SSD, so that's why they're recommended for programs, not for data.
