So yes, this SSD 840 is a kind of "under 840 pro" it to the TCL memory against the MLC to the pro version (I invite you to search on google, and more precisely on the site hardware.fr that the test two versions)
Sure, the TCL is less enduring, less effective and in writing.
But concrete is stirred the air.
For one, the life of an SSD is based on the fact of writing 20GB of data per day, and two, he should know that from a 128GB to a 256, the double life !
On this model with its 250GB TCL memory it brings us anyway to a life greater than 10 years, writing daily 20GB / day data!
20GB / day .. it will affect virtually anyone .. if not the people who make pro use (hight poly graphics, video editing, audio ..) but I imagine being aware of it. ( And nothing nempêche install the program on the SSD and make a swap HDD storage and backups .. we take advantage of the SSD speed launch programs without writing it).
And in 10 years, I hope that you have changed configuration .. :) In short, there is much more enduring than HDD final. Yet with a HDD .. we do not ask so many questions!
Performance level now.
Relatively low write a max speed below the other SSD that are sometimes twice as good.
To see what one favors .. The lightning installation of a program? Or his execution?
For level reading, it is at the top, with a 540Mo / sec throughput, and I can guarantee you it sending heavy! Everything is dependent unbelievable speed
During installation, I could not compare with other SSD .. but even if it is rather "bad" in this area, it remains to 2x the performance than HDD.
If like me, install a program, rather than in 1min 40 sec .. you matter and that you favored the execution of the program in seconds, this SSD will fit you perfectly :) 540Mo / sec SATA 3 .. it goes very very quickly!
I board.
