I picked up 2 intel 80g SSD v2 25M for a good price and was wondering if there is a controller that will have Trim? The onboard ICH certainly does not have that option.

I don't think any SATA controller will physically block a TRIM command.

What I understand (I am still unsure of this) from the TRIM command chain :

• The SSD may not support a TRIM command but it's ok with your X25-M G2 and most Indilinx based SSD
  
• The AHCI or RAID driver may NOT support the TRIM command yet ... but the "basic" MS legacy IDE/SATA driver is capable of sending TRIM commands
  
• For example, the Intel Storage Matrix drivers (supporting ICH features) should be enabled for this TRIM command "soon"
  
• At the OS level, the TRIM command must be send dynamically by the File system itself (Windows 7 NTFS should do it) or, on demand, by a specific utility (like the OCZ Wiper.exe tool which collect unused sectors from the FS - I guess it scans as an UNDELETE tool does - and send a TRIM command to the OCZ SSD - may work for other Indilinx based SSD and worth a try with your X25-M - for all of those after having created a HUGE file to reserve those sectors)

The real problem is the controller's driver and I think it will be solved by a controller driver update in the next 6 month...

Thank you for the explanation!
