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).

    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,

    But, if your machine burns a hole in /var/logs, you could certainly write a few TB of data into just a few GB of space in /var/logs every 24 hours.

      Why would writing it to /var/logs matter?

      SSDs don't work at a filesystem level. Even if you tried to burn out cells by making /var/logs its own partition, the drive is still going to wear-level amongst its flash properly.

      At least with anything resembling a modern drive. Early drives didn't handle wear-leveling worth a damn, of course.

        Well, I'm implying that they have wear leveling by the fact that they have this warranty... however, it is still possible that they have crappy or even non-existent wear leveling and the business office just made this warranty as a sales ploy.

    And, like almost every drive these days, at least 95%, and up to 99%, of the data it contains will be useless redundant junk.

      Most of my drive is filled with pictures and games. Debatably useless, but I wouldn't say redundant.

        Are those pictures and games unique to your computer or can they be found on other storage media in the world? If the latter then they are indeed redundant.

          Digital storage isn't exactly stone tablets or cave paintings. Without many redundant copies, the files could be lost forever in a few decades.

      fdupes or a filesystem with dedup like zfs, btrfs, or hammer2 solves the redundant data issue.

      Yeah, I just checked, and all the bytes on my hard disk are at some value between 0 and 255. That's very high redundancy; 256 bytes should be enough to store all those values! ;-)

    Read some of the comments people are leaving regarding how bad that company is with apparently fraudulent claims and a tendancy to screw over not only their customers but even their own employees. Seems pretty shady.

      Unless you're procuring hardware for businesses, datacenters, etc. then you aren't in the market for it.

      This at least gives us a fresh data point. 100 TB of NAND can be stuffed in a 3.5" form factor in 2018. Maybe 5 years until they will put 1,000 TB in the same volume.

          I'm willing to use a raid 10 of them for personal storage utilization if someone sent them to me. I'll write my review in 5 years..
