A functional lifespan of 10 years is already unusually high for a storage medium. Nomatter how you use it, it will last longer than the period you plan on using it (most people like to add more capacity after a certain time). Even when you push an SSD to the max by downloading lots of movies everyday up to an average of 30 GiB per day, the SSD will still last you 24 years. However, iFixit provides instructions for adventurous and skilled users. That translates to a lifespan of 75 years. 800 (DVI - Ti) 867 (Ti) 1.0 (Ti) Apple does not recommend that end users attempt to replace the hard drive in the 'Aluminum' PowerBook G4 models. The general assumption is a WAF of around 3.0 for normal consumer use with SSDs that don't employ compression tricks. That's the difference between the write commands sent to the SSD and the writes executed by the SSD internally. Keep in mind that we sequentially write and fill the SSD which gives us write amplification factor of only 1.04 or 1.05.
If we take the 764 TiB and an average of 10 GiB of writes per day, we arrive at a lifespan of 214 years. Samsung claims that the 840 SSDs are super-reliable despite the use of TLC memory, but consumers aren't quite convinced yet. TCL flash memory doesn't last as long as the traditionally-used MLC flash memory, but it's cheaper which translates to lower SSD prices.

The Samsung SSD 840 is the first widely available SSD series that uses TLC memory chips, where each memory cell can store three bits. Aside of this daemon, SSD Fan Control features a user-friendly application for monitoring and control. Whenever the SMC system resets to its default, SSD Fan Control takes over again to make sure that your system remains quiet. The core of the system is a daemon that runs in the background and takes care of the fan management. It enables you to overrule the automatic fan control and manually configure the fan speed. In both cases the SMC system tends to go into frenzy and drive you mad with a loud fan. Sometimes reusing the external sensor is not possible or, as in more recent generations of iMacs, replacing the original hard disk breaks the system’s temperature monitoring. The SMC collects data from external sensors or by reading the internal hard disk temperature in a proprietary manner. Fan management in Apple systems relies on temperatures reported by the SMC system.
IMac users who tweak their systems using 3rd party hard disks or solid state disks, are often surprised by an unpleasant aftermath: an annoyingly noisy hard disk fan.
