SSD dreadfully slow since windows 8 install

Hello,

My windows 8 felt extremely slow compared to windows 7, I mean like it took ages to install ANYTHING, worse than when I still had an HDD in here.

I checked the windows performance index, 6.8 instead of 7.0 in win7.
Something is off I thought but it shouldn't be this bad.

Then I ran AS SSD benchmark again, and a dramatic result ( in win7 I had a score of 275 iirc if not 375):

Not only is the result appalling, but it also took over 30 minutes to finish the benchmark!

Any idea what is wrong ? I haven't done anything hardware wise. I simply stuck win8 pro in, did a ''keep personal files'' install ( so clean install but not a format), and it's been terribly slow since.

It does boot quite quickly somehow, it's after logon when the slowness begins. The ssd is ''100%'' in use sometimes even just reading at 0.1mb/sec in the task manager.

Any ideas? Perhaps the storage controller drivers ?

EDIT: Installed the Intel AHCI drivers, and it's still slow, the laptop is pretty much un-usable as it is now. Any ideas what can cause this dramatic speed loss ?

have u installed the latest sata drivers?

my speed in AS SSD & ATTO went up after win 8.

Yes your WEI will go down its harder to get the same scores under windows 8.

My RAID 0 M4's get 8.2 singlt M4 got 7.5 if i remember
 
Hi snowdog,

Some ideas:

- How full is the drive? I'm wondering if the install of W8 has pushed the drive into a 'full' state which has a dramatic affect on performance. Remember that following the install you can remove win.old (google how to get rid of it).

- Check if your laptop supplier has listed a more up to date BIOS. If they have install it (My laptop is a Dell XPS 17 (L702x) and they listed a new BIOS, which specifically mentions support for Win 8)

- Try engaging the high performance plan in Windows when running benchmarks

By the way, what model is your laptop and your SSD?

If write (install) performance has degraded becasue its nearly full (or simply all blocks have partial data, so still 'free' space), on a clean install only partiton say 75-80% of the drive. This should leave plenty of space to act as a write buffer of sorts and avoid for longer the slow read/erase/writing of blocks- if that is the cause of you prob.
 
Sorry to say, but I think it's the V4 drive rather than a software issue; bouts of heavy disk activity cripples them in my experience, and a Windows 7 to 8 upgrade would probably qualify. You need to leave it "idling" overnight with minimal disk activity and you should find that the performance clears up again. Not acceptable in my opinion, but this is what Crucial advises.

Did you secure erase ssd before installing win8?

No and I'm not planning to, there is data on it I don't want to lose,

It was all fine in windows 7 though.

What I notice is, sometimes its extremely slow with the ''system'' process or some other process doing something at 0.1mb/ec according to task manager which causes 100% ssd use. And sometimes it's fine.

I just did an AS SSD benchy and it started well, well over 200mb read and 80mb write, and 4k @16mb/sec, then somehow during the 4k write test, it slowed down to just 3mb/sec write.

After stopping the benchy and restarting it, the results were again far worse.

Leave laptop for 5 mins idling, come back, and its fast again. I don't get it any more :confused:.

What I also notice is, it's lightning fast booting up, it's slower from the moment I enter my password and do the logon.

Done more benchies, read seems okay now, but writes are very odd.

The 4k and 4k-64t speeds fluctuate a lot, I'm sometimes getting results that are 10x faster or slower than the previous benchmark!
4k write I'm getting random results each time, sometimes as low as my first benchy, so around 1 mb/sec, sometimes around a still very slow 4mb/sec, somtimes around 12mb/sec and sometimes a nice 16-17 mb/sec...

Also, the write access time is sometimes off the scale, sometimes it's fine and under 0.4ms, and sometimes it goes over 1ms.

Any ideas what could cause these massive speed fluctuations ? Read looks more or less stable, it fluctuates a bit but nowhere near as much as the writes.

Hi Snowdog,

As BigToe suggested it's a good idea to leave your laptop idling at signon overnight. Make sure you set the power plan so that the SSD does not power down (HDD power off = never).

This will allow the SSD controller's background recovery functionality to do its thing to a maximum extent and hopefully your drive will get back to being fighting fit.

Big bump but just wanted to show what a lot of complaining can do, Crucial finally caved in:
Thank you for your email and I’m so sorry to hear that you’re still having any trouble with the SSD.

I actually have some good news. As we no longer supply a 256GB SSD, this will be replaced by our 240GB M500 which is our most up to date drive. This is also slightly faster in terms of write speeds and has added features such as data encryption, added protection against data loss and RAIN technology. RAIN technology is a portion of the drive that is designed to ensure the drive is always running at its optimum.

Please go ahead and send the drive to us, and once we get it, you will receive an email confirmation as soon as we receive your product, then your replacement will ship out right away, and you will receive another email confirmation then.

Please let us know if you ever need any further assistance.

Best regards,

Hopefully won't take to long for the swap and I'll hopefully have usable SSD.
