I have E7440 with Samsung PM851 mSATA SSD, which have a well-known problem of disk operation slow down (previously discussed in https://www.dell.com/community/Storage-Drives-Media/PM851-SSD-Slowdown-Like-SSung-s-840EVO/m-p/45342...
Is there any firmware update from Dell to resolve this problem? Samsung does not offer it at all.
I find the update at https://www.dell.com/support/home/us/en/04/drivers/driversdetails?driverid=rymd3 but it seems that it is not applicable to E7440.
Please tell me is the fix available?
