To get to the next level of performance in its SSD disk line-up; the new Apex series SSD is using two JMicron JMF602 Flash controller chips along with a JMB390 RAID chip. The Apex series is effectively a pair SSDs in RAID 0 "Stripe" configuration across the 2 banks of MLC flash RAM. At the top end you’ll see that the RAID setup helps the OCZ OCZSSD2-1APX120G 120GB SATA 2 Apex Series Solid State Drive and 250GB models attain a Write speed of "up to 160MB/s". But note in fine print the 60GB model has a Write speed of "up to 110MB/s" so there's a bit of an overall performance ding with the low-end, most affordable Apex model.
