I'm getting Horrible Performance from SSD!

post #1 of 11
Thread Starter 


25 MB / Second Sustained Write Speed, which is about 1/2 of my 7200 RPM HDD, I guess these things just deteriorate after 3 months of use...

Spent too much money on a complete piece of junk SSD, and that was a huge mistake...

Anyone know of how I can speed up performance?

Try a program called TeraCopy. There's vids on youtube that show you all about it. That helped pick my speeds up somewhat. Also, in BIOS are you in AHCI or IDE mode? That will make a massive difference in performance too.

You're concerned about sequential write speed... why?
Also, if you ran a lot of SSD benchmarks earlier on - you did this to yourself.

But anyway, I assume your model is using the SandForce 1222, so:

1) Make sure it's connected to your Intel sata ports (not JMicron's)
2) Make sure you're running in AHCI mode
3) Make sure the latest Intel Rapid Storage 10.x drivers are installed
4) Make sure trim is active
5) Make sure the drive has a chance to idle, if you use the computer a lot.
These controllers do their GC during idle time, so if they never idle, you will see a large reduction in performance.
Simply log off or place the PC in an (S1) sleep state over night, one or more times a week.

You are moving it from the SSD to the HDD? If so, the HDD is bottlenecking. Try to move a file within your SSD.

Exactly right

Yes the HDD is slower than the SSD obviously but even a 5400RPM mechanical HDD can transfer much faster than 26MB/s. I see 90-105MB/s transferring from WD Black to WD Black over a gigabit network.

Transferring small files can greatly affect transfer speeds. Try copying one big file (movie/ISO) from one drive to another.

--Does this matter on an AMD board?
2) Make sure you're running in AHCI mode

4) Make sure trim is active
--where do you check this?

Sleep mode runs the HD?

1) No, since you don't have the option. It's just that Intel's SATA AHCI is superior (when combined with Intel RST drivers) if available.
On AMD, just make sure to use the Windows default AHCI drivers so TRIM will work properly.

4) Technically, you can only verify that the OS is sending the TRIM commands, not that they are actually being received by the controller.
Upon executing the command fsutil behavior query DisableDeleteNotify, if the result is DisableDeleteNotify = 0, it is enabled.

5) As long as it's an S1/S2 sleep, yes. The idea is to cease CPU activity and allow the SSD to do its GC during idle time.
At the higher states, S3/S4, devices (included drives) get powered down which can affect the process.

As stated above when you transfer large amounts of very small files it will greatly affect your speeds, ssd, hdd whatever thats just how it is.

Much Thanks to Trigunflame for the help!

Well I went to Intel's Automatic Driver Update Page Got all my latest drivers.

I enabled AHCI in Windows 7, then rebooted my computer to enabled it the bios (important steps because if you enable in the bios first your OS won't load).

I changed my SATA connector to the Intel one on the motherboard instead of the standard JMicron one.

I downloaded the Intel's Rapid Storage Driver, but you have to install something else to use it, working on that now...

I will get back to you guys on my progress and tell you the results, I found 2 very interesting helpful tips, since you guys shared with me, I'll share back.

How to Check / Enable Trim in Windows 7 This was extremely useful.

I downloaded Inte's Solid State Drive Toolbox which can tell you info on your NON-Intel SSD, though it can do much more with an Intel SSD, truly. However, the above mentioned tip is 10X easier and faster.

I will list my results later, as I'm still working on getting the Rapid Storage Driver installed, any help there?

============================================
To Above Posters:

NO, I was moving from HDD to SSD, and even on a super
slow 5400 RPM drive you will get faster than 25 MB/sec
sustained write speed, I was transferring 10 GB, and
yes if you transfer 200 MB it will be faster, but not
for this SSD, it had to get some things fixed first!
