SSD file extraction speeds too slow?

Lately I've been doing a good amount of unzipping files (700MB-4GB) with my 128GB Samsung 840 Pro and noticed varying write speeds.

It starts at 50mb/sec, steadily climbs and maxes out around 180mb/sec, and starts to rapidly taper off midway through the unzip back down to 50-60mb/sec. Still snappy, but with a write speed rating of around 400mb/sec, why are these speeds so much slower? Does my SSD have a bad write latency or something?

It sounds to me like your using a Sata II port - the drive will need to be attached to a Sata III port to get the rated max speeds

I believe it's in SATA III. My PC boots up faster than my monitor can turn on...

Also, benchmarks show that I'm getting about 540MB read and 400MB write.

Then you're limitation is seomthing else... if it is dealing with .zip files, then your processor/RAM/mobo are probably running at their max ability, and that's the limiting factor - remember whenever you open or close or whatever a zip file, the computer is doing work compressing or decompressing files, so it's never gonna give you drive speeds the same as using normal files and folders

In other words, don't worry about it
