The FS-Mark benchmark results put the OCZ ARC 100 as a mid-range contender with the higher-end OCZ Vertex 3 running much faster and in some situations the Transcend SSD also was running noticeably ahead.
The OCZ ARC 100 seems to do much better with its writes than reads. However, if you're looking for a bargain priced SSD, the OCZ ARC 100 series would be a nice entry-level SSD. In particular, the 240GB OCZ ARC 100 that can be bought at the time of writing for under $100 USD while the 120GB drive I had bought goes for about $60. I'll update this review if I run into any problems with this low-cost SSD after it's been running in our large test farm after many months of automated and continuous benchmarking.
