Various Dell prices from the US website:

  3.84TB SSD SAS ISE, Read Intensive, up to 24Gbps 512e 2.5in with 3.5in HYB CARR, AG Drive 
  Dell Price $8,825.13 /ea.

  3.84TB SSD SATA Read Intensive 6Gbps 512e 2.5in Hot-plug AG Drive,3.5in HYB CARR, 1 DWPD 
  Dell Price $7,893.91 /ea.

  3.2TB Enterprise NVMe Mixed Use AG Drive U.2 with carrier 
  Dell Price $6,596.39 /ea.

I don't see a 'write intensive' option (I only looked around for a few minutes), but I can imagine them being 2-4x those prices.
