This is combined with TRIM, which ensures that blocks of memory no longer needed for storage are returned for re-use. To prevent some blocks of memory from wearing out long before others, macOS and SSD firmware use wear levelling to ensure that each block of memory receives a roughly equal number of write operations, which evens out its ageing. The two main limitations on the life of an SSD are that all flash memory fails to retain its data after about ten years, and that it can only be written to a certain number of times.
This article proposes another factor which you should take into account when making that choice: that an SSD should last longer than a similar-sized Fusion Drive. Fusion Drives would still save you money when configuring a new iMac, for example, but the difference between built-in 1 TB options is down to around $/€/£ 630, and if you could live with a 512 GB SSD instead of 1 TB Fusion Drive, that falls to less than $/€/£ 300. Now that SSD prices have fallen, and look to continue to fall at least in the medium term, the cost of larger SSDs of 1 TB or more is no longer prohibitive.
FUSION DRIVE COMPARED TO SSD MAC
It makes so much sense that the data your Mac wants most should be kept on faster-access media, and it seems silly to pay the higher price for SSD capacity to store lots of files which are seldom even read. I’ve long been an enthusiastic user of Fusion Drives.
