Do any of you know if SSD performance starts to tail off as the drive gets full? I'm thinking in terms of FSX + addons, nearly filling an SSD...I would not want to have I/O slowdown.

I think it depends which type you actually have. There are SSDs which have about 83% of it's actual capacity available to the user, and the rest is used for wear leveling. That one, I reckon, shouldn't slow down at all when full.

SSDs don't slow down as they get full.Cheers,- jahman.

HiObviously an empty SSD is faster than one that contains data, but this "slowdown" tends to plateau in use and is still much faster than a conventional HDD. TRIM and GC obviosly help. IMHO I would say that you have to get to well over 90% full to see a significant loss in any performance due to the fact that the SSD controller usually needs approximately 10% of the drive free to swap files in and out when when writing and obviously if it doesn't have that buffer performance may drop! Just a thought.RegardsPeterH

It doesn't make any sense at all that a memory addressing controller would changes it's speed no matter how much or little data is on the SSD. You don't have to move memory around on a SSD in order to get to files.... Pure Bogus ... it is the same thing as defragging a SSD drive to optimize performance... pure poppycock ....

Thanks for comments all. One thing I have read, is that SSD's performance tends to degrade over time, if many write ops are done to the drive. See the following article for interesting refernece:http://macperformanceguide.com/Storage-SSD-Reconditioning.htmlGood thing we FS guys have a lot of reads, and not as many writes, compared to some apps.

SSDs implementing the TRIM command no longer slow down after ultiple writes. Newer OSs like Windows 7 automatically TRIM SSDs, whilo for older OSs the user must launch an SSD Utility to TRIM the SSD.Cheers,- jahman.
