Comparing MacBook Pro external drive performance
July 20, 2007
Yesterday I wrote about using SATA drives with a MacBook Pro. Is it worth the trouble going the external SATA route with a MacBook Pro for editing? It’s certainly valuable when doing media ingest in the field (e.g. P2) direct to a mirrored pair of disks. I like it simply because I need to move external SATA disks between the laptop and my desktop editing systems. But there’s also a performance advantage. But how much? I decided to run a little test comparing the performance of the following:
an external SATA, a LaCie d2 triple-interface FireWire drive, and the Mac Book Pro’s internal drive. While performance among various drives and interfaces is bound to vary, I think the test confirms that unless you’re using a RAID, the fastest single disk performance you’re going to see with a MacBook Pro is with an external SATA drive.
