Compressible v.s. Incompressible Read/Write Speeds

Correct me if I'm wrong but generally speaking, I believe that most advertised read/write speeds are compressible speeds. Now does higher compressible speeds automatically translate to higher incompressible speeds?

Thanks

 

Only Sandforce-based drives advertise compressible speeds. For everybody else, compressible speeds = incompressible speeds because the concept of compression does not exist.

As for your second question, you might want to read up on how programs like WinRAR work, because it's exactly what Sandforce is doing behind the scenes - zipping up your data and then transferring it to disk.

 

very basically what winrar and SSD compression does is to transform the data into smaller size by using some algorithm. it's something like:
0100101111100111100000111010101111100001111000
could translate into:
0100105100415031010101051404140
so the size is small. that's why it writes faster. but there's data that can't be compressed. just try to compress an mp3 file with winrar or to double compress a rar file. does't work that great.
it's a mixed bag it will improve the performance of the SSD in SOME cases. But anyway sandforce SSD's reliability is really bad. And in real life you can't really tell the difference between 300mbps and 350mbps unless you run some benchmarks.

 

The SandForce drives use special compression methods. I had a SandForce drive to begin with. Despite everyone claiming SandForce being bad, enough research will show you that those paired with 34nm nand have much lower failure rates.

Anyways, I went with the Performance Pro in the end. Non-SandForce and extremely quick incompressible speeds

 

Absolutely not. Don't be fooled by high sequential reads and writes of the sandforce drives. Most of the time, you aren't in sequential read and write situations
