Hi Mickaël,

Intel X-25 M are MLC not SLC, there are very good for L2ARC.

Yes, I'm only using those for L2ARC, I'm planing on getting to Mtron Pro 7500 16GB SLC SSDs for ZIL.

and next, you need more RAM:
ZFS can't handle 4x 80 Gb of L2ARC with only 4Gb of RAM because ZFS
use memory to allocate and manage L2ARC.

Is there a guideline in which relation L2ARC size should be to RAM?

I could upgrade the server to 8GB, but that's the maximum the i975X chipset can handle.

Best Regards,
