SSDs performance issues,slow speeds,bad transfer rates,solving problems official thread

Hello guys
I just opened this thread to gather all users or members and mainly SSD owners which they have problems with their SSDs
Finding the way how to fix it and help each other to solve problems
Hope you will like it
I will post all possible tests pictures soon of my two samsung SSDs and problem with real transfer rate between them .

 

I know the SSD thread is massive, but if you search through it, you could find most of the issues that plague various SSDs and how to resolve them.

 

Actually I just recommend Musuta to start his own thread for his own specific problem.

The SSD thread has so many discussions running through each other I find it hard to answer people there.

 

Perhaps, at least for a couple of months, SSD posts should rate their own parent topic.

 

Here's some general ideas to improve performance of SSDs:

1. make sure you did a clean install, from the ground up (removing all partitions before you start by choosing custom setup)
2. install Intel Rapid Storage driver
3. try enabling write caching (Device manager → Disk → Double-click on you disk → Strategy tab → check BOTH)
4. check that TRIM is enabled (Fsutil command)
5. Disable pagefile...
6. Disable hibernation...
7. Disable indexing service...
8. Disable prefetch...
9. Disable superfetch...
10. If none of these tweaks worked check partition alignment

 

What is partition alignment, and is it needed on the new SandForce drives?

 

If you did a clean install with Windows 7 on a new drive, the partition alignment will be fine.

 

I am getting my drive today, actually What do I need to know if I want to install both Windows 7 and Ubuntu on it?

 

Hello
Am back and here is first info about my SSDs
See pictures
I will add tests as well soon

What I just ran test and I cant beliv emy eyes !!!
What the heck happened to my write ???

 

Maybe run it again? It looks like the test got aborted somehow and did not complete.

 

Musata can you post CrystalDiskMark 3.0?

 

Sorry guys I had turned off write cache ...
now its better..
am gonna downl that crystal

and here is crystal but that write seems to be low i had more before

 

I see a background in your pic so it looks like it wasn't run in safe mode. Run it in safe mode as well.

 

Can u post it on a fresh install and in safe mode?

 

Here's the updated list of SSD performance tips:

1. Make sure you did a clean install, from the ground up (removing all partitions before you start by choosing custom setup)

2. Enable AHCI in BIOS.

3. Install the latest Intel Rapid Storage driver (Download Intel® RST Driver Files for F6 Install from Intel.com. Go to Device Manager, select under "IDE ATA/ATAPI controllers" the "Standard AHCI 1.0 Serial ATA Controller". Then right click, update driver software. Browse, browse. Now browse to where you saved the Intel Rapid Storage driver. Select the folder and click OK. Reboot required.)

4. Enable write caching (Device manager → Disk → Double-click on you disk → Strategy tab → check BOTH)

5. Check that TRIM is enabled (Fsutil command)

6. Disable scheduled defragmentation

7. Disable pagefile

8. Disable hibernation

9. Disable indexing service

10. Disable prefetch

11. Disable superfetch

12. Check partition alignment (shouldn't be necessary if you did a clean install with Windows 7)

Les, if anything should be added let me know.

 

I really dont want to erase win right now .. may be tmrw..
Les - I ll try to run in safe mode

 

Phil, maybe you want to add on clean install a secure erase first and then a clean install?

 

Secure erase is not necessary cos I have TRIM now ..

 

Your 4K random write performance looks very low. I'm not used to Samsung drives though.

Have you checked partition alignment?

 

Secure erase, how necessary is that?

 

From what I've read - a secure erase is the recommended way to 'restore' like-new performance to an SSD and is also recommended before re-installing a Windows installation.

Essentially, it is the 'last ditch effort' in determining if the drive is at fault or if it's something else that is affecting the SSD's performance on a specific installation.

 

I never get my SSDs secure erased because simply there is no official program or soft for it .. all are just unofficial or old software designed for HDDs ONLY not SSDs .. I downloaded HDD erase ages ago and it simply doesn't work because it is not for it it is not supported

 

Hi i have done safe mode test an there are no changes at all

 

@Phil
Thank you for your tips i will apply them once i will reinstall winn 7

 

Thanks a lot for these tips phill.. Its something i haven't found looking through all of the SSD thread whenever i'm bothered

 

I have Vertex 2 and a clean windows 7(not cloned) installed today. Here is the benchmark. Is this normal? I think some review has better Read/write speed.
SATA II
AHCI enabled

 

It looks bad.

Have you applied these tweaks:
http://forum.notebookreview.com/har...sd-performance-tips-underperforming-ssds.html

 

Hi Phil, I think I have done all of them.

Necessary

1. Enable AHCI in BIOS.
Yes

2. Do a clean install, from the ground up. Remove all partitions before you start by choosing custom setup.
I created one 40G(for windows) and one 20G(not formatted yet, for linux use later) partition

3. Check partition alignment (not necessary if you did a clean install with Windows 7).

4. If you have an Intel chipset, install the latest Intel Rapid Storage driver
My controller is Intel 5 Series 6 port SATA AHCI. I install the full version of Rapid Storage, which comes with a control center thing.

5. Enable write caching (Device manager → Disk → Double-click on you disk → Strategy tab → check BOTH)
Yes

6. Check that TRIM is enabled (Fsutil command)
Yes The value is 0.

7. Disable scheduled defragmentation (control panel → type: defrag in search → turn off)
Yes

8. Set Windows Power Profile to High Performance.
Yes

Optional *

9. Disable pagefile (control panel → type: pagefile in search box and follow instructions)
Yes

10. Disable hibernation (press start and paste " powercfg /hibernate off " in the search box, press enter)
Yes

11. Disable indexing service.
Yes

12. Disable prefetch.
Yes

13. Disable superfetch.
Yes

14. Disable System Restore.
Yes

15. 4K Cluster size
Yes

 

What happens if you manually try to update to the Intel Rapid Storage driver I linked to?

What is your notebook?

 

It says the lastest driver has already been installed. The file is iaStor.sys Date 3/3/2010

Toshiba X505-Q885.
I attached the driver to secondary SATA and has a 7200 drive in first SATA connector. Does that make any difference? Also does 64 bit OS improve disk speed?, coz crystal diskmark has a 64 version. Thanks

 

Try connecting it to the first SATA connector.

x64 shouldn't matter.

 

I think my laptop SATA controller is listed as a PCI device. Is this causing the problem? Is there anything I can do about it?

From Everest 5.50
Device Description Intel Ibex Peak-M PCH - 6-port SATA AHCI Controller [B-2]
Bus Type PCI
Bus / Device / Function 0 / 31 / 2
Device ID 8086-3B2F
Subsystem ID 1179-FF50
Device Class 0106 (SATA Controller)
Revision 05
Fast Back-to-Back Transactions Supported, Disabled

Device Features
66 MHz Operation Supported
Bus Mastering Enabled

 

it will say, the best driver is already installed

 

is it OK to have C: Disk like this ? in Viata it never created system reserved like this

 

Yes that's normal.

 

Mushkin finally made available to users that need it a new Firmware. I am hoping it unofficially slows down the "Lifetime Write Throttling" from enabling on the Callisto Dx, time will tell. It is the update for the SF2's that fixes the SMART error on some systems.......

 

TANWare,

I hope Patriot will release a simliar firmware for the same issue. (Crosses fingers).

Does anyone know where to download the OCZ Toolbox from? It supposedly works with the Inferno I have for not only secure erase, but also as a manual TRIM tool too.

Thanks.

 

Musuta,

Don't 'ask' it to update the driver. Tell it.

Right click on Computer,
Select Manage,
Select Device Manager,
Select:
IDE/ATA Atapi Controllers,
right click on the AHCI controller,
Update Drivers,
Browse My computer for driver software,
Let me pick from a list
Have disk,
and finally, browse to the folder you have unzipped the drivers to.

Good luck.

 

man am a IT technician i know these things when i was 20 year old man
I dont need to do it coz once intel matrix storage is installed it will auto install ahci driver ...
i can install different one i know ..
there a re plenty ways to instal anything into windows ..

 

Musuta, can you post a screenshot of your SATA controller in device manager, the driver tab.

 

here is it .. before was 1.0 standard AHCI
i can have one more

 

Musata,

that is not the driver tab that Phil asked for.

 

It was not what I asked for but this screenshot also confirms that you have installed the driver correctly.

 

Phil, how can you tell (what version) is installed?

 

I said I can tell he installed the driver correctly. The reason I asked for a screenshot: On a dutch forum there was someone saying he had already installed the Intel RST driver. I asked him to post a screenshot, this was what he posted.

 

So which one then ??
mine is latest one .. should i roll it back to standard 1.0 ?

and tilleroftheearth am not musata . read my name correctly thnx...

 

It's looking fine.

 

Thnx Phil ..
and I have here more options
I am gonna try these all and will see which drvr is best ..
see pic

 

Sorry!

I did read your name correctly - just typed it wrong.

 

Musuta, have you enabled write caching?
