That tech looks super cool & might be worth waiting for, but from what I've been reading it is still being perfected and will likely see big improvements fairly quickly after release.
Heres a clip from this article I think is relevent: Teh said the new drives have double the capacity of storage systems using conventional 16TB perpendicular magnetic recording (PMR) drives, and this can be doubled again over the next four years. The company is projecting 4TB platters in the next couple of years, with 5TB coming shortly thereafter, and 6TB out beyond the current roadmap.
So there's a chance you wait for those drives, pay a little extra cuz the tech is new, then have something twice as good get released a year or two later.
It's definetly a tricky situation & ultimately up to you and what you want. Do you need that extra storage asap, or is it more of a eventually kind thing? Does new tech have its own intrinsic value to you, or is it more about price per terabyte?
Good luck with your decision! I know how hard these kind of choices can be. You never know what the market will look like after you finally make that big purchase.
Whoa it's wild that it was commissioned by a company as a way to improve staff morale after a series of mergers and acquisitions. Imagine being worried about your job in an era when job hopping was not common, & you get a smiley face pin from management.
