OCZ Vertex 2 90GB 3.5" speed check

but i can't understand why it's that high... pagefile is on another drive, and when i encode videos i always make sure the temp and output folders are on another drive...

have you disabled the hiperfil.sys file, cos if you haven't and you use sleep, it copys the data from your memory to the ssd, everytime you sleep your pc.

Have you disabled indexing to your ssd?

Ive left my pagefile on the ssd cos its recommend that it stays on the ssd.

This is my ssd info..........

i haven't disabled the hiperfil.sys file. surely if i disable it the system won't sleep or have issues when waking up?

yes i've disabled indexing .

i moved the pagefile because when i'm encoding videos it uses all my ram then it uses 4-5gb of pagefile.
 
"hiberfil.sys" is only for hibernation, it doesn't affect normal S1 or S3 sleep. Removing it if you don't use hibernation is a good idea just because you get an extra 4, 6, 8 etc. GB of free space back and free space is important for an SSD's garbage collection and wear levelling.

At the moment every time you sleep your pc, it will be copying the content of your memory to your ssd. This is because if the power fails while in sleep, it will pull the info back from the ssd/hdd. Sleep and hibernate uses the hiberfil file.

You will notice if you disable this, your system will sleep quicker, cos its not copying the content of whats in your mem to the ssd

This is how to disable hibernate/hiberfil........

Open command prompt and type:

powercfg -h off

ok thanks mate.. i just done it..

does anybody knows the answer these 2 questions. i've asked on ocz forum but i can't get a straight answer yet

1. do these sandforce drives need trim in the driver to let the recovery system kick in?
2. if the answer is no to question 1., would going in the bios or boot in to dos and leaving it for afew hours, still let the drive do it's recovery?

No, cos its in the firmware, like it will even do its thing without the sata cable connected.. That might be another option if you want it to speed up the process, disconnect the sata cable when your not using the pc.

TRIM and the duraclass technology re-cycling, wear levelling and general house keeping etc. (Garbage Collection by another name) are two distinct processes.

And as I've said before, just logging off for a few hours a day should do the trick under normal use. Also as I said in an earlier thread, after almost a months pretty heavy use on my own system, there is no noticeable degradation in sequential write speed. Either perceived speed loss, or from running AS SSD again (almost identical scores in the sequential read/write). Obviously a lot has to do with work / usage patterns.

Should maybe point out that pretty much all the other tests (IE. random read/writes and lightening fast access times) remain pretty much unaffected. Even degraded, a decent SSD should still be MUCH faster then any mechanical drive out there.

Though once again ... I think that SSD development and also to an extent how these are tested (IE. benchmarks) have a long way to go. Pretty much still at the start of the development road for these babies. Interestig times ahead me thinks.

TRIM tell the drive as soon as you've deleted files then it deleted the page. TRIM doesn't need log off time has it does it straight away..

the Garbage Collection needs logoff time so the drive can recover.

have i got this right?

Almost.

Garbage Collection will work in any idle time, it's just that logging off makes it's job just that little bit more easy. Or so say the boys in the know (supposedly).

Mind you. TRIM processing is probably not even as straight forward as that. It's really up to the firmware in the drive as to what it actually does with the command that gets passed to it.

I think it's quite easy for your head to explode if you start thinking to much about these sorts of things. As you've probably noticed, even on the OCZ forum, you sometimes get conflicting advice.

Yes it would.. as long as power is maintained to the drive.

great.. does that include TRIM still do it's thing, by doing it that way? if yes , how does the OS (the windows on the normal hdd) know which file as been deleted from the ssd (which i boot from mainy)?

It (OS) notifies the controller via bitmapping routines.. it will only notify for data/metadata deleted (marked invalid) from the SSD.

or does TRIM tell the drive as soon as you've deleted files?

Yes.. as above.

or TRIM tell the drive as soon as you've deleted files then it deleted the page.

TRIM deletes nothing.. the OS deletes and sends the ATA TRIM data set to Notify the controller that the space 'vacated' by the delete is now 'invalid'. The controller can then merge/combine/erase/re-programme 'blocks' full of invalid pages.

TRIM doesn't need log off time has it does it straight away..

TRIM is just a notification from the OS to the controller.. once it's been sent, the controller makes use of the Log Off/Idle Time.

the Garbage Collection needs logoff time so the drive can recover.

Yep.

have i got this right?

You should now..

so i've boot in to windows from the normal hdd and disabled the ocz ssd in device manager so it won't be intrepid.

i've had an idea. what if i put the ssd in a External Hard Drive Enclosure, then that way when i turn off my pc, i could leave the ssd on all the time..

would this work?

As long as there is still power supplied to the drive, then I expect so.

Though is there no period during the day / evening that you can't just logoff for a couple of hours each day? As this is really all it should require. And to be totally honest, if your SSD is degraded too badly, then no amount of idle time GC (sorry... re-cycling) will totally recover the drive performance back to factory spec.!

Does this mean that you not going to be using this as a boot drive now?

it'll still be used as a boot drive.

my idea was to use/connect the power only from the External Enclosure then make a hole in the Enclosure so i can route a sata cable from the ssd to the sata backplane on my case which would be connected to port 0 on the motherboard.
 
i'm giving it one last chance.

i'll start again, secure erase it then reinstall windows, i'll logoff for 2 or 3 hours everyday before i turn off the pc and go sleep..

one other question. if the drive gets throttled is it still safe to use or could it damage the drive/controller if continued to use?
 
"if the drive gets throttled is it still safe to use or could it damage the drive/controller if continued to use? "

From what I can gather, it is perfectly safe to continue using your SSD. The drive (or rather the firmware) is just trying to adapt to your usage pattern and is attempting to prolong the life / usability of the drive.
