Notes on data warehouse appliance prices

Curt Monash:

Reasons people criticize per-terabyte data warehouse appliance price metrics include:

  • Price-per-terabyte metrics ignore issues of throughput, latency, workload, and so on.
  • Price-per-terabyte metrics ignore quality of storage medium (slow disks, fast disks, Flash, etc.)
  • Price-per-terabyte metrics can be radically affected by changes in disk size.

Not a specialist, but I don’t think the price-per-terabyte includes operational costs either.
