Tom's Hardware decided to check up with Samsung about what's going on with the 850 Pro 4TB SSD. This MLC-based model has long been rumored since the arrival of the 850 EVO with 4TB of TLC-based NAND memory, it was mentioned in a CES press release but is still not available.
Samsung's press agency replied the 850 Pro 4TB is delayed due to the worldwide shortage of NAND flash memory:
“As a result of the worldwide NAND shortage, Samsung is focused on allocating NAND to products where we see the greatest demand. We will let you know when further updates on the 850 PRO 4TB are available.”
As the site reports, this is the first official confirmation of a retail SSD product that has been delayed due to NAND shortages. Several other solid state disks are in short supply and prices are rising due to the shortage:
Rumor has it the early 960 Series products destined for consumer shoppers were scooped up by datacenters. The series, the Pro model in particular, delivers exceptional performance and endurance for a consumer SSD and rivals many of the existing enterprise-focused models shipping today. There was a lingering suspicion that the low volume at Newegg and Amazon were a combination of datacenter purchasing and supply-side troubles.
Some chip makers are converting DRAM production lines to NAND, which in turn will result in a DRAM shortage later this year.
