Tran Log backups on FusionIO cards are 6 times larger

We added FusionIO cards to a database server. HP recommends changing the sector size from 512 to 4096 for SQL Server. We did that and moved our log files from DASD to the FusionIO cards. The backups are now 6 times larger but the database activity has not changed.

Has anyone else experienced this?

    Could you please post the contents of a SQL Backup log file for the backup of a transaction log that grew in size?

    The default folder where the logs are stored is C:\Documents and Settings\All Users\Application Data\Red Gate\SQL Backup\Log\<instance name> on Windows 2003 and older, and C:\ProgramData\Red Gate\SQL Backup\Log\<instance name> on Windows Vista and newer.

    Could you also please post the contents of a log file for a transaction log backup prior to the switch to FusionIO?

    You didn't mention what version of SQL or O/S you were running?
