What programs are out there to help keep SSD array performing it's best?

post #1 of 9
Thread Starter 
I've heard terms like 'garbage collection' and the like being thrown around and would like to know what programs are out there that can help with the deteriorating performance that comes with a raid 0 array since using trim isn't an option?

NO tony trim!!

So...what you are doing with Tony-TRIM is erasing all data on free or marked deleted blocks so they do not have the erase before write speed penalty. To help the drive free up space you need to consolidate free space which will increase write cycles to the drive much like GC FW does...Then you run AS-Clean to reset all those now free blocks. So TT is more like manual GC than TRIM really.

You will get an instant speed up by doing this...BUT you have to make it part of your SSD weekly/monthly care regime for it to be most effective.

So...you run Tony TRIM and after a week the drive slows down again...why?

Windows writes randomly with often tiny fragments of data, when a small fragment hits a block it gets written to it, but in order for that block to see another write it has to erase first...hence the drives slows down once all free clean blocks have been used. This is why regular maintenance helps keep drives fast.

Yes, it's called TRIM.

TRIM will be included in the next ATA-ATAPI spec revision.

NO I MEAN NO, tony trim was ment more for gen1 drives, not gen2.

there is so much gen 1 tweaks and twists floating around the net that the gen2 drives do not need as there is already better ways or software out there.
I see so much GEN1 drive info posted and very little GEN2 drive info and people do tweaks that are not needed with gen 2 drives.

What's the difference between a Gen 1 drive and a Gen 2 drive that doesn't support TRIM or GC?

Hmm, well my drives are gen 2 so I guess there is nothing that I can do except wipe/reinstall OS every couple of months?

Anyone have a download link to a wipe program?

Also, I know how to check if TRIM is on in Windows, but when does it do it's thing? At idle? And how long does it take to complete the task? Is there a way to monitor this?

Well at the moment, if you have a RAID Array, it won't do it's thing... Windows sends the TRIM command to the hdd controller driver every time it deletes something, the controller driver then passes that command on to the drive (or not in the case of some drivers) and then the drive will schedule that block to be pre-erased, or marked blank or whatever it does with the info... In the case of a RAID array, the block may be in two parts (because of the striping), and no-one has stepped up to the task and written a RAID Driver that does TRIM too... Although I suppose if you did Software raid through Windows it might work... but you can't RAID a startup (boot) disk so that's kinda pointless... and it might not work anyway.

Sadly there is no way to tell if TRIM has happened, other then benchmarking at the moment...

You can disable Windows from sending TRIM commands using the fsutil command, but you can't check if it's working anywhere...
