Windows 7: Show us your SSD performance 2

Wow, great numbers

2 x Vertex 4 128Gb RAID0:



Numbers seems too low for me, I have no idea what to try to improve, tired all options from AHCI to RAID, different RAID controller etc. Still doesn't come as high as it should.

Welcome to Seven Forums ericvvl. I'm sure our experts will have some thoughts. In fact, download AS SSD. You don't have to run the program, just open it and post a snip.

Thanks, here is AS SSD screenshot:

Eric your numbers are a little lower than Dwarf's, but you shouldn't notice any performance issue. If OCZ has some kind of tool box, see if you can invoke Garbage Collection.

I have Z77 Asus Maximus V formula, it has TRIM with latest version of Intel Rapid Storage anyway/
I checked with CrystalDiskInfo, it show TRIM on both drives in array.

TRIM is different than Garbage collection.

Ah, I thought those are two names of same technology.

Nevertheless, OCZ Toolbox is used only for firmware updates and doesn't even show drives in RAID at all. Only information can be obtained via CrystalDiskMark. Is there any way to check if GC is enabled? Because I am suspecting that it's should be controller function (not OS-driven, like TRIM) which should work any OS, any configuration?

I'm going by what Crucial told me, I have an m4 SSD. They said for Garbage collection to run the drive has to be powered up with no read/write at all. They suggested leaving the system set in BIOS or powering up with the SATA data cable disconnected and leave it for 8 hours or more.

As I understand it, TRIM will move old data from a NAND cell to a cache so that cell can be used again. Garbage Collection takes care of deleting the file TRIM has moved but takes longer.

But Crucial uses Marvell controller, that procedure could be different for Indilinx-based OCZs I guess.
