Researching a possible upgrade to a single 240GB SSD for op sys, all the stuff I bought in the Steam Summer Sale (!!), other nuts, hoping for a performance boost over existing RAID 1 HDD. The array will then end up being relegated to a general dumping ground for apps I loath as much as Word and Excel and pictures of a dubious nature.
Reading other threads, have seen Diskmark is a good benchmark tool to run to get stats about current throughput of the RAID array.
What other tools are there I could use to "predict" performance in the "real world" after a change to SSD?
I ran Crystal Disk Mark, showing that I am getting Sequential Read speeds of around 50MB/s, and writes at around 140MB/s. I was expecting much higher read speeds, always thinking that a RAID 1 would have meant much better read times, randoms at least. Apparently not. THat answers my first question - RAID 1 on an ICH7 is no where near a competitor to SSD's likely speeds.
Sites testing the GT show about 300/400 MB/s (1) and I would therefore expect the corsair, let alone the 830, to decrease the disk bottleneck by 70-80%. From the earlier article, I'm expecting a big gaming performance increase on load, but the rest won't really benefit.
Then I used Treesize to see what is creeping over 240GB on my system drive.
In other words, I could barely get games on to that SSD. or be forced to do stupid things like copying steam games back and forth between the HDD and SSD whenever I wanted to play one rather than the other, bla bla bla.
But my question is answered: yes, performance boost; no, not enough space.
