My current system has a slow hard drive, through a PATA interface. SATA interface is not an option. I am planning to replace the HDD with an mSATA SSD through a PATA adapter, though this will not allow TRIM to be used in this machine, because PATA cannot support these commands.
I am not trying to get full SATA transfer rates, only to eliminate the delay of a slow mechanical drive.
My question, is that since TRIM will be disabled in this machine, can I periodically remove the SSD and move it to another machine with a SATA controller, to run cleanup operations to free up unused data blocks from there? Does anyone foresee any problems with this arrangement?
SOLVED: It appears PATA drives suporting TRIM do exist, and ATA-7 PATA controllers may be able to use TRIM to manage SSDs, with a suitable bridge.. Credit to Groo for suggesting this.
