bump

Plug in a Firewire drive then try it, see if the SSD speeds increase.

 

[SuperMiguel]

um what u mean?

There are quite a few cases that if you plug a firewire drive into a MacBook then your SSD benchmarks go up. One person saw almost 50% increase in the speed of his SSD RAID

just plug it and unplug it and that makes my raid be 50% faster?

Leave it plugged in, when you unplug it will slow back down. How much speed you get depends on the drives.

It's a bug in OSX.

There is a few posts on the forums about it, and there is a post about it at Digitalloyd. It probably hasn't gotten much attention because not many run SSD RAIDs in their MacBooks and even less are testing the speed and even less then those are testing the speed and happen to have a firewire drive in.

how about regular use? how can i get the best speed on regular use? i always have to plug a firewire drive to get the best speed?

Until Apple fixes it, yup.

Also, dont use xbench, its way out of date.

Dang this is pretty sick. Do your X25Ms have the TRIM update installed? I know that Mac OS X won't support it, but I've heard that it increases performance (although this is being debated iirc).

what should i use?

 

[altecXP]

You'll have to look around, I just use AJA but its not at thorough as others. Xbench is not BAD, it's just not ass accurate as it can be, since its 4yrs old.

I have it a slight bit on my i5. I believe it has more to do with the controller then the CPU.

Just borrow a FIREWIRE drive from a friend and find out.
