SSD Cache in surveillance server

[Gummibaer]

Hi guys,

 

I'm looking for a solution for my surveillance server.

The issue is that videoplaybacktimes and timeline scrubbing is really slow with an HDD(6TB) but a big SSD would be too expencive.

I'm useing the video timeline only about twice per day and store 7 Days of recordings before I automatically delete the oldest data as a complete day.

One day of data is usually arround 400gb to 500gb worth.

So I would like to store one day on an 500gb SSD and transfer the oldest data on an HDD if possible.

OR

If possible, I'm looking into SSD caching with an SSD(500GB) and the HDD(6TB), now, what SSD caching type would be the best for this scenario? Or do you guys have a diffent idea for faster speeds?

 

Thanks in advance!

(Sorry for my bad english!)

seems like a really convoluted solution.. so let me spin it another way:

 

if you capture about 500GB a day worth of security footage, i'd state that you must have the budget for a propper storage array to put this on.

rather than figuring out SSD caching, figure out a way to replace the (singular?) HDD by a RAID array (or ZFS or w/e) of 4-8 drives either 2 or 3TB in size.

 

also, my guess is that the reason scrubbing is so slow, is because you're basicly hammering that hard drive with writes from the camera feeds, keeping very little "seek time budget" availabe to you interacting with the device.
