I was really hoping they were going to finally be selling an SSD that was an order of magnitude less costly than spinning rust. That's about what it would take for the tradeoffs in reliability to be worth it.
- ocdtrekkie 7y agoQLC-based SSDs are coming very close to parity with cost/capacity of traditional hard drives. Terabyte SSDs are now sub-$100, which isn't that bad at all. Note that the reliability concerns about SSDs have seemed mostly overblown, after years of abuse and testing.
- mjevans 7y agoI've seen the prices on QLC SSDs. I feel like currently they MIGHT reach the same price as spinning rust. At that point it's a trade between seek time and reliability. Within that context I still see spinning rust as the longer term archive / bulk storage media. The QLC storage might provide a good precaching layer in more complex systems, and might eventually reach it's seemingly intended price point (rather than being a small discount to TLC drives that are more mature and higher performing). The 'order of magnitude' I'm hoping for might be as small as binary (half) for me to consider it... but at 10X the storage per price it's where I hope something with no moving parts and less drive housing should be.
