My experience with many OWC drives is they are rock solid, but that price is a bit high for a bus powered 1TB SSD. Many other name brands (SanDisk, Samsung, WD) are around $150.
However it does support E-SATA, an external supply, has a power switch and allows swapping out drives to add capacity down the road which you might find useful enough to justify the higher cost.
