MX200 240GB - Incredibly slow read/write speeds & loading times?

Hello,

 

Around four days back, I noticed that my computer was being incredibly slow when booting up. This just happened suddenly, there was no warning or indication that this would happen.

 

I opened up the tower, checked all the connections and replaced the SATA cable, all the while ensuring that it was plugged into an Intel-controlled SATA3 port.

 

This didn't change anything. When I boot up, it will take around 5 minutes to get to the login screen, and then from there it will take 20-30 minutes for everything to stabilise so that I can load up programs & applications. I have also just upgraded the firmware for the SSD to MU04.

 

I decided to download a couple of SSD benchmark suites, all which gave the same result - the SSD was seriously (and I mean seriously) underperforming:

 

Here is a copy of my SMART tab from the Crucial Storage Executive:

 

To clarify: I am running Windows 10 (64), i7 4790k, 16GB RAM.

 

Any ideas, anybody?

Hi Reslivo,

 

If you can, try to test the drive in different PC. SMART data looks okay to me. 

I think that at first glance it looks like it could be some problem with drive power management - check if the Windows power plan is set to 'High Performance'.

Unfortunately it's not possible to try it in a different PC as there isn't easy access to another one within the next couple of weeks.

The Windows Power Plan is set to high performance, has been since I put it all together I think.

Could you please post text output from AS SSD Benchmark and CrystalDiskInfo? Just please remove drive serial number.

 

With CrystalDiskInfo use 'Edit > Copy' option.

With AS SSD Benchmark use 'Edit > Copy' option.

 

Edit: Did you try to run chkdsk on that drive?

[ Edited ]

Unfortunately I don't know whats going on. Everything looks okay except the speeds.

The only thing I noticed is that your system is using generic AHCI driver from MS. If you are not using eDrive/bitlocker disk encryption you could try to install proprietary driver from Intel - https://downloadcenter.intel.com/product/55005/Intel-Rapid-Storage-Technology-Intel-RST-

You may need to try older versions if the newest ones would say they don't support your hardware and refuse to install.

Re: MX200 240GB - Incredibly slow read/write speeds & loading times?

Thanks, bogdan.

 

I've installed the Intel RST, and it just seems to have made things worse. It now takes longer to load into Windows and login. CrystalDisk detects that Intel is in fact running the controller now, too, and not Microsoft. This all seems really strange to me.

 

In addition, my browser hangs on "Waiting for cache..." and my games freeze too. It's almost like my PC is having trouble reading the SSD at frequent intervals.

 

Would this be one for the customer services team?

You have excessive kernel io causing sluggish device access.

 

strip the machine back to basics and add things back slowly.

Personally I would probably try to test the drive in different system and/or reinstall OS, just to be on the safe side. 

But yeah, if you fell it is necessary you can get in touch with Crucial customer service anytime!
