Mine (a laptop), runs 24/7, I do a bi-weekly defrag of the HDD. As far as I know, there is nothing we can do about the SSD. I have not found any evidence to the contrary that defragging the HDD has been detrimental. My boot times over the past year have stayed consistent at 31 seconds (this includes doing the bi-weekly defrag for those 12 months, on a bi-weekly basis).
I have not found any info that states anything about TRIM or looking after the SSD.
I use Mechanic Pro 10 for maintenance,and it always shows 'NO SSD' drive found. Sooo... I take that to be a good thing. I have updated my Mechanic Pro to 11.1 and still, 'NO SSD' Found.
That has been my experience for the last year.
Update: This is what I found on the Seagate message board:
The Momentus XT Adaptive Memory algorithm is an LBA-based algorithm that looks for small portions of data that take the drive a disproportionate amount of time to access. It then puts these portions of data in the Solid State storage for quicker access. A disk defragmentation operation in some cases will move these small portions of data and as such invalidate the need for having the previously associated LBAs in Solid State storage. However, Seagate's analysis has shown that many of these data portions are not moved with a disk defragmention because, while small, they are entire 'files' which the defragmentation cannot determine a need to move.
With this understanding Seagate recommends that a user should run disk defragmentation on a Momentus XT for the following reasons:
- Disk defragmentation will be beneficial for data that remains on the disk.
- The majority of the data that was in the Solid State storage prior to the defragmentation will still benefit from being in the Solid State storage after defragmentation.
- In the case where the data that was in the Solid State storage no longer benefits from that location the Adaptive Memory algorithm will appropriately remove it and free the space up for more pertinent data.
