how long before the impact of my ssd performance over time or just will run slow will it slowly kill the ssd ?.PS i am a noob and thanks for your help
The problem comes when the ssd needs to do an update, and there are no free nand blocks.
The ssd must then do a read/rewrite cycle to do an update.
TRIM works by freeing up nand blocks when windows deletes a file. Otherwise, deleting a file will involve a read/rewrite cycle.
And... putting both ssd's in a raid array increases your chance of catastrophic failure. You lose all data if either drive fails.
OCZ, more so than crucial has had more than it's share of failures.
