My OCZ Vertex 2 Saga

Write caching?

Tried every combo of the 2 checkboxes

I've got a returns number from Novatech and will probably post it back tomoz. Problem is trying to think how they can quickly replicate the issue...

Toms recommended a Kingston v+ so will probably get one of them.

[AlienALX]

It's not up to them to replicate it. How long have you had it? Could be a CC snatchback.

Edit. What bios mode do you have it in? If it's AHCI put it in IDE.

[midnightray]

I purchased it on the 10/11/2010 (10th of November to Americans) on a debit card though

Damn, had it in the AHCI mode as I assumed that was the best and recommended, thought IDE was for XP only. I had Win 7 x64 pro installed.

I'll probably be dropping it off Saturday (snow permitting) so I guess I could try IDE, but won't that screw the performance and give possible BSODs?

[AlienALX]

LOL that's probably your issue. AHCI *HATES* SSD with a passion mate. I can't even get mine past the driver install stage.

AHCI is not official supported on OCZ SSDs and may under some circumstances affect performance,

benchmarks for SSDs and HDDs alike, but can cause hang-ups and intermittent freezes in SSDs since it allows multiple access requests to compete for a drive that is not made to address re-ordering of commands in the queue. We recommend AHCI is set to disabled in both Windows and in the BIOS.

Native Command Queuing greatly increases the performance of standard rotational drives but it has no bearing on SSDs.

BTW dude, to add. If you disable it in BIOS and the problem persists then I'm afraid it means a complete reinstall. If Windows has already set up AHCI you may have terrible trouble getting it back to the std M$ storage controller. So please don't disable it in bios and go into Windows thinking that if it's still doing it then you haven't fixed the issue. Please try both before you resign the drive to going back.

You should see what it did to my Corsair when I ran AHCI lol.

[midnightray]

Oh, OK WTF. Everything I read from OCZ and people on their forums is to get it set AHCI. You got a source for that quote.

Very confused atm then.

[AlienALX]

Absolute OLBOCKS.

According to a bulletin on the OCZ site

See? just goes to show the spastics you are dealing with.

Now that I have reverted to IDE Mode, the SSD is instantly responsive. The slightly higher (+0.2) performance index using AHCI is a false indicator of real performance. In this case, real-world performance actually suffers considerably.

See? Sound familiar mate?

[midnightray]

Wow, wow, wow. Might be the silver bullet!

But:

I have an Acronis image of my SSD when I installed using AHCI only. Can I use it and just tweak some settings? Or do you recommend a full reinstall/wipe with it set to IDE, also it says set IDE in windows, any idea how to do that?

Edit:

OCZ replied, appears not

That is outdated material and was applicable to first generation SSD's with the Jmicron controller.

Dude try it any way.

Also, fresh install. I use Acronis and it's flaky at the best of times.

Thing is, if you don't try everything and it works you'll only be getting it back again any way tbh.

Let's face it, you haven't got much to lose (and my Corsair uses Indilinx)

[midnightray]

Gonna buy a Crucial one and give that a shot probably tomorrow.

Tonight I will format + install win 7 in IDE and see if I get the freezes still.

All I've read about IDE mode is that it makes your benchmark scores lower, but not much difference in real world usage.

So I will give it a shot.
