Yes, I am aware that it does not currently support TRIM, and I knew that going in. Frankly, calling it a major disadvantage isn't really accurate--the Intel drives have extremely good used performance without it. Any increase in latency is going to be tiny. My 4k random I/O numbers are still quite a bit better than a single drive.
It's likely that a new generation of Intel RAID drivers will support TRIM, but again, it isn't as huge of a deal as some make it out to be. > -----Original Message----- > From: hardware-boun...@hardwaregroup.com [mailto:hardware- > boun...@hardwaregroup.com] On Behalf Of Eli Allen > Sent: Thursday, January 14, 2010 10:25 AM > To: hardware@hardwaregroup.com > Subject: Re: [H] New Video Card survey > > One major disadvantage, you can't use TRIM on the drives and I'm > guessing the raid will increase latency a bit. > > Eli > > On Thu, Jan 14, 2010 at 9:18 AM, Greg Sevart <ad...@xfury.net> wrote: > > Yes.
