did you have Fast Path enabled when benchmarking?

The 9260-8i with LSI firmware updated per LSI suggestion killed the read to 1.8GB/s, same as the write. Very unhappy!!! Warning about the firmware and motherboard, consumer boards may not support operation after upgrading firmware & LSI will not assure you that it will work after an upgrade. Their support is not good. I suggest 4 drives as the max if using 256GB or larger SSD. I also leave 150GB free space (never fill up the drives). Tried 3, 4, 5, & 8 drives, Performance degraded after 5 drives. I used the X25E for over 3 years, and yes, requires sleep every night. I now changed to the 128GB Plextor Pro5. Hence the need for 5 due to the 330MB/s write. Reads do NOT improve after 4 drives. Although it also requires sleep for max performance, the reduction without sleep was not as severe as the X25E. I run the system 24/7 and use for simulations and very large files (including photography & audio). And hoping to get into 4.2.2 (near raw) 4k @60fps video soon. The Samsung 850 Pro or 840 Pro is certainly worth trying out. Would be interesting to see what 24/7 operation without sleep will do to them.

Because these are SATA 3.0 6Gb/s drives, you most likely don’t need all 8 SSD to max the 1.8 Gb/sec write and 2.8 Gb/sec write limit. I believe 4-5 SSD such as 4x Samsung 850 PRO 256/512/1TB should hit the write limit, with 128 850 PRO being a tiny bit slower @ 470 vs 520 write, 5x Samsung 850 Pro 128GB should hit the upper end of the write speed. But in order to see the 2.8Gb read, you will need at least 6 SSD drives @ 550MB/sec each.

I have been using the Vertex 30GB and the Intel X25E 30GB in Raid0 with 4 drives each as my system drive. The killer is that they quickly slow down, the Vertex were worse. But even the SLC X25E, they bog down. They both required SLEEP every night to recover. The Vertex would never recover for very large file transfers. And one finally died within 2 years of use. The SSDs as a work station are okay even if some times i will run simulations that I may do over night. As a server or where it is operational 24/7 without sleep, you are killed!!!

What SSD’s are out there that have good enough Garbage Collection that will allow operation 24/7????

TRIM? How about if these SSD are filled in RAID 0 and start to slow down?
Is TRIM supported with this controller?

SITE RESPONSE: TRIM is not supported in any RAID configuration whether ti be soft or hard with a controller such as this. This is where it is particularly smart to know that the drives you are utilizing have excellent ITGC (Garbage Collection) abilities which take care of the TRIM issues and ensure there is no slowing over time.
