Hi guys, so I debating whether I should get another
Kingston 64GB SSD that is used. Well I am quite paranoid that when RAID 0 these 2 SSDs that TRIM will be unactivated. Is this true?
It is, TRIM currently can't be passed on a RAID, but Intel is working on a new driver to allow it. It should be noted though that most modern controllers support their own internal form of TRIM which can help keep SSD's in a RAID running efficiently.
What about the failure of one SSD? Is it common? What causes the failure?
The firmware of an SSD is usually responsible for any problems an SSD has, many controller manufacturers over the years have had to deal with issues in their firmware.
One of the more recent and largest spread firmware bugs was with drives using a SandForce SF-2281 controller, the firmware had a power management bug which was causing the drives to disconnect from the system while active causing the OS to crash, and requiring the user to do a hard shutdown and reboot.
SandForce released a firmware update back in October, after working on the issue for months, and were able to increase the stability of the drives for many users, they also just released another firmware update which is supposed to have many more fixes in it.
Unfortunately some users still have problems with SF-2281 drives, so purchasing one can be a gamble, but the odds of having issues have gone down quite a bit.
Leaving the computer on for long periods of time, which affects the SSD array? Should I just invest in a 120GB SSD instead? The only reason why I want to RAID 0 my current SSD is to salvage it instead of leave it sitting. Opinions are greatfully appreciated.
Thanks
I would purchase a new SATAIII 120/128GB SSD, their prices have really come down this past year.
Though I don't know where you live, here in the U.S. you can find good deals on SSD's at places like Newegg.com.
