840 or 840 Pro on SATA II

post #1 of 4
Thread Starter 
Hi, I'm looking to buy a SDD for my sig rig.

Will I have any sort of benefit by choosing a 840 128GB Pro over the 840 120GB non-pro? Or being on SATA II will bring the same performance on whichever I choose?

Alternatively I have Plextor M5S 128GB for a bit more that the non-pro - would it be worth it or it too would be bottlenecked?

You aren't going to notice any differences. I hear the Pro has a longer life than the non-pro, but they are both long enough where you'll likely replace it before it dies anyways. The Pro has a 5 year warranty and the non-Pro has a 3 year warranty.

I noticed you are not in the US, you may want to verify those warranty periods where you are from, as I was assuming they are the same everywhere.

Unless you are using large sequential file reads, something most people do not do, the strength of an SSD is not it's transfer rates but it's seek time.

Typical computer use and gaming are not about reading single large files in order. Rather it is a hit and miss of many small files and often only a small part of them. This is exactly what the low seek times of an SSD benefit most.

I can tell you I have the pro and the none right now and the only difference I saw was it took about a minute longer to install Windows on the none. As far as day to day use I cannot tell the difference and that is on a SATA III system. The non pro should do fine for you..

Thank you for the answers. I think I'll go with the 840 non-pro and it has a 3 year warranty period (In 3 years time I hope to have replaced my sig rig anyway biggrin.gif )
