Should "New" clips be written to the C drive only?

I'm trying to troubleshoot random crashes when triggers occur. Nothing in the BI log or Windows Event Viewer. I was writing to an external drive and changed it to the internal SSD C: drive and the random crashes continue. Thanks

Video should not be written to SSDs. They should be written to surveillance grade HDDs like WD purple drives.

====================================
My Standard allocation post.

1) Do not use time (limit clip age)to determine when BI video files are moved or deleted, only use space. Using time wastes disk space.
2) If New and stored are on the same disk drive do not used stored, set the stored size to zero, set the new folder to delete, not move. All it does is waste CPU time and increase the number of disk writes. You can leave the stored folder on the drive just do not use it.
3) Never allocate over 90% of the total disk drive to BI.
4) if using continuous recording on the BI camera settings, record tab, set the combine and cut video to 1 hour or 3 GB. Really big files are difficult to transfer.
5) it is recommend to NOT store video on an SSD (the C: drive).
6) Do not run the disk defragmenter on the video storage disk drives.
7) Do not run virus scanners on BI folders
8) an alternate way to allocate space on multiple drives is to assign different cameras to different drives, so there is no file movement between new and stored.
9) Never use an External USB drive for the NEW folder. Never use a network drive for the NEW folder.


Advanced storage:
If you are using a complete disk for large video file storage (BVR) continuous recording, I recommend formatting the disk, with a windows cluster size of 1024K (1 Megabyte). This is a increase from the 4K default. This will reduce the physical number of disk write, decrease the disk fragmentation, speed up access.
Hint:
On the Blue iris status (lighting bolt graph) clip storage tab, if there is any red on the bars you have a allocation problem. If there is no Green, you have no free space, this is bad.

What version of BI are you running? The 5.3.3.x are having crash problems. As the previous two posts mention, don't write video to a SSD drive. Video belongs on metal platter drives.

Thanks @SouthernYankee, great info!

I have two drives in my BI computer. The C: drive is an SSD and the "Storage" drive is spinning disk. I have tried storing new clips in both places and random crashes are still happening when cameras trigger. Not every time though. Based on what you posted, I have configured new clips to be stored on the storage drive. I've allocated 85% of the drive and I'm not using Stored which is set to zero.

With these random crashes still happening, I'm at a loss to figure the root cause. Is there a way to turn on verbose logging, because the standard log and Windows Event Viewer are not showing anything.

Thanks!
 
Again, what version of BI is running on the machine?
Machine specs, processor with more detail that just i5. Memory. Hardware acceleration.

Thanks @sebastiantombs, here you go.
I'm running v5.3.2.8.
Using Intel +VPP Hardware Acceleration
11 2MP cameras running 15 fps
Using sub-streams and CPU steady 25% - 35%

Try installing 5.3.2.11 That' been very stable and is listed as the "latest stable" update by BI. Have you tried changing acceleration to just, plain, Intel or any of the other variants? If you increase RAM to 16GB and can use dual channel, your CPU utilization will probably drop significantly. Also watch the CPU temperature, IE make sure the CPU cooler is clean and the same with the power supply.

I'll try v5.3.2.11 and see how it goes. I tried regular Intel with the same results. Unfortunately my Dell OptiPlex 3010 doesn't support 16GB of RAM. Not sure about the CPU temp etc. Is there a utility for checking that?
 
"Core Temp" will show the the temperature and utilization of each core. "GPU-Z" will show CPU temp and load, as well as the load on any graphics cards that may be installed. I'm not sure if it'll show the load on built in graphics, I only have external cards, but think it probably will.
 
Let's see how 5.3.2.11 does. Mem test might be next.
