CentOS 6.6 SSD trim on HP DL380 G2 RAID 0

I'm running glusterfs on CentOS 6.6 two nodes, (the SSD (samsung 840 1TB x2) is RAID 0 on the HP DL380 G6) x2, and trimming is not enable on it by checking /dev/sdb1/xxxxx/discard_max_bytes=0. Do I still need trimming? Somehow my filesystem is fine with 35-30% free space and running very fast.

Thanks for any comment you may add.

RAID 0 for SSD

Nowadays the fastest SSDs achieve read-speeds of between 1500 MB/s to 1900 MB/s. Let's say that two such SSDs in RAID 0 achieve roughly double the throughput, ie 3000 MB/s.
