Internals, RAID 0

Here I have removed the back cover from the Apex which is easily done by removing four small screws. Do note, however, that doing so will void your warranty with OCZ.

OCZ is using eight Samsung 904 K9HCG08U1M PCB0 memory chips on the top (presumably the same number on the bottom) of the PCB. You can also see the dual JMicron JMF602 B controllers and a single JMicron JMB390 A RAID controller chips. The JMicron JMF602 controllers have been used in several SSDs and have a bad reputation for causing stuttering, but these are revision B controllers which JMicron claims improves write latency. That, plus the fact that there are two of them should help a lot.

The internal RAID 0 configuration is a neat idea from OCZ. Essentially there are two 60 GB SSDs here, each with its own JMicron JMF602 B controller and the JMicron JMB390 A RAID controller configures them in a RAID 0 setup. This splits the data between the "two" drives and greatly improves performance, just like a traditional RAID 0 array would. The computer still sees the Apex as a single drive which makes management no different than any other drive.

During the initial testing and tweaking process of the first Apex I received, OCZ sent over a second Apex to help narrow down some issues I was experiencing (more on that in a bit). So now, with two Apex 120 GB drives, I decided to compare the single Apex to dual Apex drives in RAID 0 for this review. 240 GB of SSD loving in RAID 0 - do I have your attention now?

But before we start, I need to discuss some things concerning SSD usage, what to expect and how to get the most out of your drive.
