i also have the pay version. will also give it a Chance.

Hi folks, I can tell you: this Data-Compression thing is not useless ! 

I'm operating P3D v4 on a Crucial 500GB SSD (see here , if interested).

• Before compression I had 227 GB of disk space occupied.
• After compression there was 163 GB of disk space assigned.

....which means a reduction of 64 GB and a gain of 64 GB more storage on my SSD (which is really notable).

Till now I haven't recognized any gain or loss of performance during flight sim operations, but at least write amplification should be reduced which can increase the endurance of a SSD significant (not to mention about free disk space - SSD are expensive and P3D inkl. all its addons needs a lot of memory location).

 

Resume: Nothing speaks against data compression; positve aspects prevail.

Guys, what are your own experiences?

Best regards to all of you,

To me, other than saving space there is no benefit. Other than extreme situations, the amount of disk space available has little effect on performance. Considering that every disk read during flight ( and there are MANY) needs to be decompressed and every write needs to be compressed - this takes CPU cycles. Probably negligible with today's processors but still additional overhead.

I do NOT know but I suspect that compression might shorten the life of an SSD - again I am assuming here that the technology increases disk writes - I may be wrong on that.

There would be less data to load over the life of the flight with the added decompress time as a factor but that would be done in memory.  That could lead to better performance but there are many factors.  If your drive loads like a banshee now there may not be a big difference.

Still give it a try on your system.
