Now in stock at OWC, the Hitachi Deskstar 7K3000 offers 3TB (three terabytes!) of space on a single hard drive.
The interface of the Deskstar 7K3000 is SATA 6Gb/sec, which should also be backward compatible with existing SATA and eSATA devices, at least in most cases, and in some cases once firmware updates are made.
I’ll be testing the 7K3000 soon, and I’m looking forward to seeing if it can hit speeds in the 160MB/sec range, but also whether any compatibility issues arise in the Mac Pro itself, in my SeriTek 2EN2 enclosure, or in the iStoragePro.
The 7K3000 also has a 64MB data buffer for increased performance with some types of disk access.
With idle power consumption of around 6.8 watts, it’s not an ultra low power drive, but neither is it a hot-running drive, and for the performance and capacity it offers, it’s very reasonable, and notably lower than the 8.1 watts of the Western Digital RE4 2TB.
I can see using the 7K3000 for high end video storage in enclosures like the iStoragePro iT8SAE, but also simply ignoring the capacity, and using them for the high performance (assuming they pan out as expected).
