There's one more point to consider, though. With information being compressed on the fly, you're consuming more of an SSD's available write cycles than if you were writing the files uncompressed. This could have negative implications on the drive's endurance. Although we're not necessarily concerned about larger SSDs, models with less capacity inherently have lower endurance ratings. Thus, NTFS compression could conceivably affect their useful lives more significantly.
The highlighted part has me confused. Isn't compression and decompression done in memory? How would that affect the SSD's write cycles?
