OCZ Vertex 2 90GB 3.5" speed check

i had to use Parted Magic . was easy to do once i got Parted Magic working. it took all day yesterday just to do this Secure Erase, :(

i wished i didn't get a ssd. lol
 
does this look right?

my write speed is back to 137MB~ in CDM but my read speed still the same in CDM

Yep. The partition alignment is spot on.

Not sure why your CDM results are so far behind mine. Might just be the controller / drivers on your mobo. Probably nothing you can do about it. But if the ATTO benchmark looks OK, I would not worry about it too much.

These are my figures just after installing W7:

If you want an "expert opinion" I would strongly recommend posting a query on the OCZ SandForce sub forum.

PS. Remember if using CDM to drop the file size to 100MB and set the number of runs to 3.

EDIT... I don't think anyone has asked this yet. But what firmware is your drive running?

Second EDIT. I see your disk is marked as #3. If running this as a boot drive, they usually recommend that you run it in the first SATA port. Though got to admit that I don't know too much about this motherboard. Looks like it's got more than one controller. Or have we covered this issue already? Contributing to a number of similar threads at the moment and somewhat loosing track!

firmware is 1.24

yes i droped the file size to 100MB and set the number of runs to 2 instead of 3.

my write speed is about the same has yours but the read speed is about 50MB under yours.

ATTO benchmark results are fine.

so i guess it's my motherboard controller doesn't like CDM, lol

it's in port 0 on the motherboard.

yes it as 2 controllers.

ports 0-5 are amd sata III controller. ports 6-9 are gigabyte sata II controller

Opinion seems to differ. I've just left it where it was.

OCZ suggest:

"In Win 7 put it on your SSD."

See http://www.ocztechnologyforum.com/f...BC-for-OCZ-SSD&p=567567&viewfull=1#post567567
for lots of helpful hints and tips.

To be totally honest... I have not tweaked anything at all. As far as I'm concerned, if it's Windows 7, then most of the important things are already done for you (EG. defragmentation it automatically switched off for your SSD).

Up to you really. A lot of people bang on about optimising this and that. But not convinced that you really need to do much (anything?) really.

they say to disable Prefetch, BootTrace, Superfetch , but i thought windows 7 automaticly does this?

As far as I can see. OCZ says :
"Best to let Win 7 manage Windows Accelerators.. do not disable manually. "

If it was me. I would just leave them alone. That's what I've done / do.

I doubt to be honest that disabling them will make any noticeable difference (either way) to performance.

Up to individuals if they want to tinker further.

My motto is "if it aint broken, then don't fiddle".

May I chime in a little here and ask a few questions as I have a Vertex 2 120Gb SSD on order and am getting a little worried about getting it now that I ahve read this thread:

1.) I can understand that trying to bombard the drive with lots of un compressable data can cause the drive performance to degrade. Can this be fixed by secure erasing?

2.) Why do you not partition these SSD's? and is this true of all SDD's?

3.) Would you reccommend a different SSD instead?

4.) Why do OCZ reccommend leaving the PC on but logged of for a few hours each week?

5.) Why was sleep mode reccommended to be avoided with an SSD?, can sleep mode still be used as I currently use it a lot. and if sleep IS to be avoided is this true of all SSD's?

I hope you guys can answer my questions

Thanks

Neil

1) Yes. But then you will obviously need to re-install Windows etc. (or recover the install from a clone).
Depending on how much you have de-graded the drive.... over time it will recover to a certain extent. This should NOT be a problem in normal use. Only if you continuously run benchmarks like CDM!!!

2) I think you may be confused. When installing Windows, you just let the install process partition the drive (obviously you can tell it how to do it if you want).
This is just as much as anything, to make sure that the partition alignment is correct.
If you've never installed an OS before, I would STRONGLY suggest looking at an install guide (there are loads on the WEB). If you know what you are doing, then ignore this remark.

3) The Vertex is no different from any other Sandforce based SSD. And the Vertex 2E is still one of the best IMHO. They (like any SSD) are not really as plug and play as Mechanical Hard Drives. Though not much to it really. As I keep saying to folks, read the guide on the OCZ Sandforce forum. Everything you need to know (preferably before hand).

4) This is something to do with letting the drive recover (related to TRIM I'm guessing). Though some folks will tell you it's not necessary, I am more inclined to believe the experts (NB. the OCZ forum is not just a "user forum" some of the mods are OCZ techie employees).

5) There are some sleep issues still with the current firmware on theses drives. Loads of posts on the OCZ forum about it. Though I'm not sure if it effects all motherboards / BIOS combinations. I always disable sleep and don't let the SSD switch off (power options). So if this is an issue for you, do a bit of digging on the OCZ forums. Can't say I've looked too closely into this, as it does not effect me.

I still think if you use theses drives like any other, they are great. I certainly have no complaints.

I think Ocz recommend the log off and leave idle for a bit, to let the controller do its thing (garbage collection), kind of how with intel drives u can run a weekly clean up via there tool box, just with the sandforce drives they do it, itself when left totally idle.

I personally won't bother with doing it at a given time each week myself, i'll just do it when i know im away from my comp for a good while, so instead of just leaving it on, i'll log it off instead, so atleast that way i know the controller is doing its thing, and keeping my drive ship shape.

I noticed that after my fresh install my ATTO bench was about spot on, few Mb/s slower then some but nothing to worry about, went to town yesterday, let it logged off and idle, and low and behold, ATTO bench was up, so yup the controller is cleaning it all up when in idle.

The sleep thing is i just think its one of those quirks SSD's just don't seem to like it to much, maybe a controller or maybe a trim issue who knows, iv had an intel drive and now the vertex, i turned off sleep for both. They boot so damn fast anyways u don't really need sleep.
 
The Vertex 2 drives do not support Garbage Collection as per some of the older drives. TRIM is really meant to replace this. Though I do believe that the Sandforce controllers do some sort of house keeping / wear levelling etc. when the PC is idle and this is I think where this comment about "leaving the PC switched on but no logged in comes from".

Sleep /resume problems have been around since the early days and don't just effect SSD's. In fact some folks don't appear to have any problems at all in this area. While for some others, the latest firmware for their SSD looks to have sorted it. Though a number of folks still look to have issues in this area. Can / could be so many different things causing / contributing / interacting to cause this. Very much a "suck it and see" sort of thing.

Can anyone just explain what the information in ATTO Benchmark actually means. What does all the 0.5, 1.0, 2.0 mean down the left side?

and what do all the top options actually do?

I have the following specs from my current drive and want to check them with what ATTO is showing as I ahve just run it. What things do I actually need to compare?

Seek Times
-Read Seek Time 4.6 ms
-Write Seek
Time 5.2 ms (average)
-Track-To-Track Seek Time 0.4 ms
(average)
-Full Stroke Seek 10.2 ms (average)
Transfer
Rates
-Buffer To Host (Serial ATA) 1.5 Gb/s (Max)
-Buffer To
Disk 84 MB/s (Sustained)

Hi ... not being cheeky, but there is a reasonable HELP function built into the ATTO benchmark.
