That is pretty awful write performance. Does anyone know more about this? I assume all of these hyperdense SSDs suffer from the same drawback. Also, I heard that the E3.L interface can support up to 16x lanes, but there are no practical commerical products at this point.
Consumer and data center drives play by different rules. The super high write speeds you see for consumer SSDs are usually achieved through tricks like using sections of the drive as a high-speed buffer and then using a background process to rewrite the data into the drive's high-density NAND storage during downtime. They can also use caching techniques that aren't resilient to power loss. They might allow burst performance that heats the drive up until it throttles.
This is all fine and even desirable for a consumer who will only be writing for at most a minute or two, but with a 245TB server drive you need to assume the performance will be needed constantly. They target sustainable and predictable performance.
A more convenient (and dare I say, faster) tape drive replacement for backups? They do make a good point, it would take 10*24TB drives working in the worst raid configuration to even come close to these speeds.
The interface looks equiv to 4x PCIe 5.0.
