Yea, enterprice line have different price structure. Usually, they are priced higher than the consumer conterparts. However, we can get cheap used enterprice drives, just without warranty.
One big problem however: $1600 for a 30TB drive (do not buy the 32TB SMR one) is ~$55 per TB.
Compare that to, say, the Solidigm D5-P5336 that cost ~$3.7k for 61.44 TB, the cost is $60 per TB.
Although recently the 61.44 TB drive has gone to $7k for some reason, that’s $115 per TB. Either Solidigm is milking their product, or they did not anticipate this level of interest, or they did not manage to ramp up capacity fast enough. Whatever it is, well, the SSD is clearly winning in the enterprise.
