The time has come to lay my money down. On storage, that is. Real storage, not home-made hodge-podge RAID arrays that I’ve built myself throughout the years, just to save some money. Yes, it’s saved me a lot of money, but now that my current workstation has only Thunderbolt and no internal eSATA support (obviously it’s an iMac), the time has come to invest in a proper Thunderbolt RAID system.

At first I had been using an old Drobo 4-bay enclosure as my storage array, but of course that wasn’t fast enough to edit video. It was just used as an archive. Then I started making RAIDs out of various inexpensive external enclosures, until now. Currently, I am using two Vantec HX4R 4-bay enclosures with 8TB each on board, configured as RAID10. The HX4R is an eSATA device, but since the iMac doesn’t have eSATA ports, I had to hook them up through a LaCie eSATA>Thunderbolt hub.

The LaCie hub is a bit of a mixed blessing. On one hand, it is super-fast and works very well, when it works. For the most part, it’s fine, but it has a tendency to cause drives to unmount spontaneously. Of course, this is no good when you’re trying to work. To its credit, it never did it when the unit was under heavy use; only when it was mostly idle. But still, it’s not good for drives to be spontaneously ejected, of course. Lately, it’s been causing problems with one of my RAIDs, in the form of corrupted directories. It spent the last 48-hrs refusing to mount correctly, so I figured it is time for a change.

Tomorrow I will put my money down for a new Promise Pegasus R6 RAID array loaded with six 3TB drives. When searching for Thunderbolt RAIDs, the Pegasus kept coming up tops and the specs are good, so I figured it is worth a gamble. It’s expensive, but if it holds it end of the bargain, it will save me that much more money in wasted time. I will write a review of the Pegasus R6 after I’ve had some time with it.
