SSD Write Endurance 25nm Vs 34nm

[Anvil]

The question is, what do we want to know?

100% incompressible data is of course an option as long as the static part of the drive is filled with realistic data, e.g. a Windos 7 installation.

100% incompressible data is just not possible as long as the drive is used as an OS drive, OS and applications are roughly 50% compressible, possibly more if one uses the pagefile.

By using 100% incompressible data it would mean that the answer one would get is, the quality of the NAND used, the abilty of the SF controller to do wear-levelling of both static and dynamic data, (can't think of any others right now) but one of the main points with the SF controller would be totally lost, which is compression.

Of course I agree with you about what is a proper way to conduct such a test, which in short = knowing all the varialbles.
Real-Life just isn't like that, so we need a lot of SF drives to get the anwers we want.

To answer your question about 46%, it's just a level of compression that is a likely average for all files on your OS drive. (an SSD in particular, storage excluded)

From what I've found playing with compression on the SF 12XX controller there aren't that many "levels" of compression.
Meaning that when you reach a certain level of compressibility it doesn't matter if the data is e.g. 30 or 40 percent compressible, they are handled with the same speed.

We can't get all the answers using 1 SF drive so it's just a matter of making a decision about whats more important.

We need more SF drives to get to the answers
