MX200 - weird SMART parameters - 09, 0C, AD, B7.

Hello. I recently bought Crucial MX200 as an upgrade for my 2011 Dell XPS laptop. Everything works fine, but it gets weird in SMART..

 

First of all - power on hours, power cycle count is wrong - 1hour in SMART = ~10 hours in real. But one thing bothers me more - B7 parameter (SATA Interface Downshift). Currently it is 78 (i think that is correct power cycle count).

 

Also AD parameter (Average Block-Erase Count) shows 2. Is it possible if total bytes written = 209GB (according to Crucial software). I thought that one cycle is 250GB written (one full erase cycle). Am I wrong?

 

Is something wrong with my SSD?

Re: MX200 - weird SMART parameters - 09, 0C, AD, B7.

Hi sernik92,

 

Modern SSDs can put themselves into a very low power consumption modes and thus, with those modes enabled, Power-On Hours attribute excludes any time the drive spends in a 'sleep' state.

 

I think that SATA Interface Downshifts shouldn't usually happen and they could possibly indicate bad SATA cable or malfunctioning driver perhaps? What is the exact model of your 2011 XPS and what SATA driver you use? You can check the driver version with Device manager -> IDE ATA/ATAPI Controllers -> right click on the selected controller -> Properties -> Driver tab

 

AD attribute shows average NAND erase count and NAND writes are usually higher (few times higher) than host writes, at this point I wouldn't worry about it since it looks normal.

Re: MX200 - weird SMART parameters - 09, 0C, AD, B7.

Thank you for your reply. Smiley Wink

 

My exact model of XPS is Dell XPS L502X. Yesterday I uninstalled Intel Rapid Storage Technology, which caused that power-on hours were counted correctly, but MX200 got much more hotter than before (average temperature is 35-38 Celcius, but without IRST - 10 degrees more) so reinstall was needed. Smiley Wink Tried updating Intel chipset driver via Intel Driver Update Utility as well, but after installation my laptop was booting slowly (stuck for 7-8sec at "Welcome" in Windows7) and also working slower than before so I reinstalled previous chipset driver. Everything works fine now, but I'm concerned about SMART parameters (especially B7).

 

Info from Device Manager:

 

Intel(R) Mobile Express Chipset SATA AHCI Controller

Driver provider: Intel

Date: 2011-01-12

Driver version: 10.1.2.1004

 

Cheers. Smiley Happy

Re: MX200 - weird SMART parameters - 09, 0C, AD, B7.

I don't know what driver was installed by Intel Driver Update Utility but I think I would try 11.7.0.1013 on that system. It is not the newest one but it should work well on your Dell I believe.

Re: MX200 - weird SMART parameters - 09, 0C, AD, B7.

Installed, after reboot Windows told me that "Crucial ATA SCSI driver installed and ready to use", rebooted once again but no effect. Still every reboot increases SATA Interface Downshift by 1. Is it bad for the drive?

Re: MX200 - weird SMART parameters - 09, 0C, AD, B7.

I don't think it is bad for the drive. This attribute is informational only and if the drive stays SATA3 during normal use and in benchmarks then most likely you could ignore it. 

I think I would suggest updating SSD's firmware to MU02 (with Manual Boot File method) and also checking for BIOS update for the notebook.
