You’ll have to keep waiting for pricing. The 1TB, 2TB and 4TB models are available today at respective prices of $130, $250 and $500, but the 8TB version doesn’t arrive until August and doesn’t yet have a price. The pricing model suggests it may cost closer to $1,000. That wouldn’t be outlandish for what you’re getting, although it’s definitely not a trivial purchase.
There’s one main issue: the competition isn’t standing still. Sabrent recently introduced an 8TB SSD of its own, and that’s a PCIe drive with much faster transfer speeds. It costs a hefty $1,500, but the premium might not be that much of a deterrent if you can justify an 8TB SSD in the first place. Samsung’s offering is more for that subset of enthusiasts (and certain pros) who can afford a capacious drive but still need to keep their costs vaguely in check.
