SSDs are not created equal

I suppose the motherboard/controller makes some difference but SSDs vary greatly in performance. The disappointing Samsung performance is running on a 3GB Intel controller which could be the issue.

Here is my first one. It is in my notebook and I am very happy with it but it is not top shelf. The good news is it is a larger drive and I could feel good about installing some programs on it because I really don't want it to live forever. Real world performance from my user perception is pleasantly fast and responsive. My notebook is a decent Intel dual core so it was a good performer but this SSD really brought it to life.


My second one is a Plextor M3 Series PX-128M3 for $99 which performs much better. I have not timed the boot to Windows desk top but we are talking seconds. It runs on an i5-2500K overclocked to 4000 and the speed is blazing. 


My third and soon to be installed somewhere is a SAMSUNG 830 Series MZ-7PC064B/WW 2.5" 64GB SATA III MLC. User experience reports are impressive if my luck holds. I am looking forward to the fun. I paid $64 from Newegg. They had a 256 for $190 and its reads are reported to be 700 vs 500 but the way I set these up I do not need that large a boot drive. Yes, the larger drives could be considered a "better deal" in dollars per GB but why pay for more than you need. I will probably symbolic link the program folders on this one in addition to the users folder even though it is large enough to have a good supply of programs in addition to the operating system. I'm still hung up on not writing to the drive.

Here is the Samsung and it is disappointing compared to the Plextor M3. It starts out fine but I don't understand the severe drop. Normally the speed variations are due to another program's drive access but both drives on the 3GB controller show large variations. The drive on a 6GB controller is constant across the drive. Also the Samsung is a gen 3 drive and showing as gen 2 so I question how accurate PCWiz is at reading the controller and drive separately but it does read the controller correctly as opposed to reading the drive only.

Pin Not Available

Crazy Error I had not seen before. Pin not available blah blah. I restarted a few times and it finally worked. If it doesn't some say to...
