Among the different configuration options available when using the OWC Data Doubler in your MacBook or MacBook Pro is setting both drives to function as a RAID 0 (striped) array. This combines both drives (the one in the Data Doubler equipped optical bay and the one in the original hard drive bay) into a single volume, which provides an increase in data access speed.
Since we’ve had several questions about this, we decided to put this configuration to the test by using different combinations of hard drives and SSDs to determine which offered the best balance of price, capacity and performance.
Our test machine was a 2011 13″ MacBook Pro (MacBookPro8,1) with a 2.3GHz Intel Core 5 processor and 4GB of RAM. Inside, we replaced the optical drive with an OWC Data Doubler to allow us to utilize a second drive.
