People generally understand that there is no guarantee of the ratio of data reduction, as it is highly dependent on workload. So, the best metric for comparing the capacity is “usable capacity without any data reduction” of the very basic unit of the all-flash array. Current models of AccelStor NeoSapphire all-flash arrays come with 1TB - 13TB usable capacity in a single 1U or 2U basic unit (without stacking), all under a reference price of US$100K. With such a budget, other vendors can probably only offer less than 3TB usable capacity.
