Dose this look right?

Hi all, just got my ssd corsair force GT SSD and install Win7 etc and did some benchmarks dose this look right to you?. Have a look at both pictures. Just want to now why the read speed is so much more then write. Thanks:)

With the current problems the drives are experiencing the speeds are normal but Corsair and Sandforce are working together to fix that.

 

is AHCI enabled?

Latest BIOS?

Plugged in the SATA 6GB Port (Intel Controller)?

Updated Chipset drivers?

Installed IRST?

AHCI - Yes

Yeh

No sata2 becuase I dont have sata3

Yeh

IRST? What is it

 

---

 

Also every time I benchmark my SSD dose it lose performance etc to the nand

if it is plugged in the SATA 2 port then the speeds are fine.

 

IRST = Intel Rapid Stoarge Technology

 

if you don't have any problems such as BSODS then you don't have to install it.

Okkk + Answear my question I have benchmarket my SSD few times is that bad or good thing todo? and if it bad can I undo it?

don't regularly benchmark your SSD. it will slow the SSDS performance. So from now on don't benchmark your SSD until you experience some slowness.

Okk:) + Is there any program or anthing out there what can tell me how well my SSD is in like healthy etc or not healthy...

that would be SMART. but the SSDS dont have some of the sensors for SMART so it would be no. But not to worry TRIM is keeping the SSD to reduce the writes it does.

OKkk but I might of damage it by benching it? through so whats schould I do...

There are loads of programs available that'll show you SMART data from the drive.

 

Although some of the traditional attributes (or rather their names) don't apply to SSD, there are others that do. There's another sticky post dedicated to SMART info if you fancy reading it.

 

Here's what SMART data from my Force GT looks like...

 

 

Benching it won't damage it so to speak... it just means the drive has performed a bunch of writes that it need not have done - and of course these things don't last forever :)

 

If you perform too many write operations (especially when there's not much space left on the drive), it'll throttle the speed. Then I believe you have to wait for GC (aided by TRIM) to kick in and tidy up. I think there's also something known as a lifetime throttle (where it throttles the speed to prolong the life of the drive - unless they're one in the same?!) where you may have to SE the drive to fix/reset it.

IS this any gooood >>> http://www.upload.ee/image/1580300/clipboard_upped.png

It's really only the 'pre-failure' attributes you need to worry about.

 

All of those are still at their initial values (of 100 or 120) and far from the 'Threshold' values - so yeah, it's fine.

Okkk, How old is your SSD and which one do you have?

Also I dont get what your saying hear

Somthing about rest?

It's a Force GT 120GB and it's brand new (not even partitioned or formatted).

 

Which bit don't you understand exactly?

 

I'm not going to attempt to explain how the SandForce controller works. I'm sure if you Google 'SandForce Throttle' you'll find some info posted by people more in the know.

I understand, but I dont get whats the whole point in secure earse. when when you benchmark your pc it decreases your performance.

Secure erase isn't a benchmark.

 

It totally wipes the drive and will restore any performance you've lost due to the over use of benchmarking tools. (Then you need to partition and quick format it again + reinstall or re-image it).

 

For the most part, I'm sure that if the read speeds are correct, the write speeds will be too - so you could get away with just doing 'read' benchmarks.

I was told when you benchmark your SSD if you do it enought time you will loss performance and there is nouthing you can do.

That might be when the lifetime (or hammered?) throttle has kicked in.

 

Google 'lifetime throttle secure erase' and I'm sure you'll find an interesting discussion on the subject.

 

Just don't run an endless number of benchmarks that write to the drive - there's no point anyway. You can perform 'read only' benchmarks on it all day and it won't do any harm.

 

When you've secure erased a drive, I understand that it'll return to peek performance (advertised speeds). Once you've written to every bit of the nand at least once, the drive has to erase as it goes (if GC hasn't already done it?) and that's what slows the writes down.

 

It's the difference between being able to just paint a room or having to strip the wallpaper before you can paint it.

 

If you go crazy with writing LOADS to the drive, only time will release the throttle. So if you wrote 100TB in 1 day and the throttle kicked in, you may have to write next to nothing for the following month to average out the writes/time and get it to release the throttle.

Ok but secure easres dose no harm to your PC through?

Also when I did my benchmarks I used ATTO Benchmark - AS SSD benchmark. Dose the write or just read the nand?

Ok but secure easres dose no harm to your PC through?

 

Define 'harm' ! It wipes your hdd. If you've got important data on it that isn't backed up, I'd call that harmful. If you know it's going to erase everything and don't care, no it's not harmful. It doesn't touch anything else in the PC, it's just the SSD. Secure Erase is peformed internally BY the drive. Software tells it to do it and it does it to itself.

 

It does erase all the nand though so I guess that's 1 off however many it can do in its lifetime.

 

Dose the write or just read the nand?

 

If it shows you a value for write speed, it has written!

Yeh ik about wipeing your SSD but dose it do any harm apart from wipering. Have you got skype? or msn so we can talk on there instead?

You're way too paranoid. It's fine.

What programs schould I use to read my SSD then for my speeds etc?

ATTO. Run it once.

 

Also, repeated benchmarking is not healthy for an SSD and can also cause performance to slow down.
