Is possible to overclock a SSD?

Anyone already had tried to or knows if it is possible to implement in some way an overclock an SSD (or get the same benefits by tunning some parameter on an SSD)?

you cant overclock them but you can raid0 them – Uğur Gümüşhan – 2016-09-07T21:49:18.663

SSDs usually fail in less than a 1.5 years (http://www.codinghorror.com/blog/2011/05/the-hot-crazy-solid-state-drive-scale.html)... you want them to fail faster?

Flash memory is limited by a fundamental access time: for 25nm Intel flash it takes 50 microseconds to read 8kB; this translates to 156MB/s, per NAND chip (with typically 8 or 16 NAND chips per SSD that can be accessed in parallel). Yet typical SSD sequential read speeds are 200-400MB/s.

So, in theory, there is still scope for improving SSD controllers (as well as the SATA interface/host adapter) even further. But, for present drives, it's unlikely that there's anything useful that could be tuned by the user that the manufacturers have not already considered. I suspect that the cost and complexity of the SSD controller sets these boundaries on performance.

If it was possible without breaking the drive you would need access to the firmware, but companies do not allow that for obvious reasons. The best you could do is make sure your drive's firmware is up to date or buy a faster drive.
