Personally I would replace your D: drive with a small 7200 rpm drive as you do not want to be using a SSD for heavy writing tasks. Then I would get the green drive out of the editing path and use it for backup/archiving only. Since you have a RAID 0 array for your project files, exporting to a single green drive will be much slower that exporting to your RAID array. Now if you can configure another RAID 0 that would be ideal for the exports
If I would replace my 240Gb SSD to a 7200rpm HDD this will not be much slower like before?I thoght that media cache drive must be a fast drive.This Corsair HD tune test show around 300Mb/s average speed.And If I take out the corsair, where can I use?
I agree with you about the export drive.
Here's the deal:
While SSDs are fast, they also have limited rewrite life. And when an SSD is used as a media cache dribe, it can use up its entire rewrite life cycle in only a few weeks to a few months of use! This is because media cache requires repeated rewrites to a disk.
In this case what if I put the corsair for an export drive? I render large files only a few time/month.
And I would buy another 2 * 7200rpm hdd RAID0 for media cache? But I m afraid there is no more free sata port on my Asus P9X79 pro. In this case a RAID controller will be necessery?
