We have a number of Granite 9 dataloggers, and have had failures with the SSD memory on more than one. We are writing to table files on the drives, at a relatively high rate, but other operating conditions such as environment should not stress the logger or memory unduly. Campbell Scientific UK are aware of this, and one suggestion is that the drives are replaced with the SLC memory type as in the XD spec for the Granite 9. Just wondering if any other users have encountered these failures, and how they were resolved ?
