disk IO increased while dedup was on, although it didn't from the ESXi side. Could it be that dedup tables don't fit in memory? I don't have a great deal - 3GB. Is there a measure of how large the tables are in bytes, rather than number of entries? Chris -Original Message- Fr

They are fast when they are new. Once all the blocks are written, performance degrades significantly. SLC will also degrade over time, but when it needs to erase blocks and rewrite, it is much faster than MLC. That's why for ZIL, SLC SSD is prefered. It's possible to remove MLC ZIL and use wipe

You can use the utility to erase all blocks and regain performance, but it's a manual process and quite complex. Windows 7 support TRIM, if SSD firmware also supports it, the process is run in the background so you will not notice performance degrade. I don't think any other OS supports TRIM. I
