Nimbus Data has announced 50 and 100 terabyte datacenter SSDs with five years of "unlimited endurance" at the maximum 500 MB/s write speed:

Nimbus Data on Monday introduced its new lineup of ultra-high capacity SSDs designed to compete against nearline HDDs in data centers. The ExaDrive DC drives use proprietary controllers and NAND flash in custom packaging to offer up to 100 TB of flash memory capacity in a standard 3.5-inch package. The SSDs use the SATA 6 Gbps interface and are rated for 'unlimited' endurance.

The Nimbus ExaDrive DC lineup will consist of two models featuring 50 TB and 100 TB capacities, a 3.5-inch form-factor, and a SATA 6 Gbps interface. Over time the manufacturer expects to release DC-series SSDs with an SAS interface, but it is unclear when exactly such drives will be available. When it comes to performance, the Nimbus DC SSDs are rated for up to 500 MB/s sequential read/write speeds as well as up to 100K read/write random IOPS, concurrent with most SATA-based SSDs in this space. As for power consumption, the ExaDrive DC100 consumes 10 W in idle mode and up to 14 W in operating mode.

[...] Speaking of endurance, it is worth noting that the 100 TB drive comes with an unlimited write endurance guarantee for the full five-year warranty period. This is not particularly surprising because it is impossible to write more than 43.2 TB of data per 24 hours at 500 MB/s, which equates to 43% of the 100TB drive. For those wondering, at that speed for five years comes to ~79 PB over the 5 year warranty of the drive (assuming constant writes at top speed for five years straight).
