OCZ Vertex 2: Couple questions on this SSD.

[iHalo]

Will I face decay?
Is it the best SSD in the 200-300 range for 120 GB?
If I fill it to 120 GB, will it run slow at max capacity like a harddrive would?

Bit skeptical on the switch now that I learned SSD's can face decay and eventually be slower than a 5400 RPM drive...

Will I face decay?

Modern SSDs don't really suffer from this unless you writing TBs of data in it per day. Maybe in few years the performance will be few percents slower.

Is it the best SSD in the 200-300 range for 120 GB?

Likely yes. All SF based drives are pretty much the same

If I fill it to 120 GB, will it run slow at max capacity like a harddrive would?

Yes. Try to leave at least 10% free space. If you need more than 120GB, get a bigger one right now
