So what exactly is a professional SSD, you ask? Take a look at the Sony G Series Professional SSD’s outstanding longevity ratings, and you’ll have your answer. Where the average mainstream 480GB SSD is rated for around 180TBW, i.e., the number of terabytes that can be written to it over its lifespan, the Sony is rated for a whopping 1,200TBW. Throw in a twice-the-average 10-year warranty, and yowser! More peace of mind delivered by anything other than Intel’s Optane SSDs.
But while the G-Series won’t set you back as much as Intel’s Methuselah-like Optane, they’re more than twice as expensive as the average NAND-based SSD. That begs the secondary question: Do you actually need that kind of endurance? Not likely if you’re an everyday user, but we don’t need sports cars, either. That’s why the super-reliable G-Series makes for interesting reading.
