SAS hard drives by cost per terabyte
12Gb/s SAS is where the cheapest bulk terabytes live, because the second-hand supply is enormous and consumer buyers can't use it without an HBA. Budget for an LSI/Broadcom card in IT mode and remember that 520-byte-formatted drives pulled from arrays need reformatting to 512 before a normal OS will touch them.
As of 14 October 2026, the lowest cost per TB for SAS hard drives is $7.50/TB: the Hitachi Ultrastar 7K6000 2TB SAS, used, at $14.99 delivered (price plus shipping), from eBay. How this is calculated.
