- miahi 14y agoOf course they will. I don't think we will see >1TB drives without it.
- shabble 14y agoAre you referring to https://en.wikipedia.org/wiki/Advanced_Format https://en.wikipedia.org/wiki/Advanced_Format? I'd not heard of it before, and a quick poke at the internet doesn't really show anything beyond a move to 4k sectors (and therefore presumably less efficient storage for lots of small files). Is there something more I should know about? (in the market for a new home storage box soonish)
- miahi 14y agoYou get a huge performance impact if the OS doesn't align the clusters to the sectors. From the wikipedia article: The translation process is more complicated when writing data that is either not a multiple of 4K or not aligned to a 4K boundary. In these instances, the hard drive must read the entire 4,096-byte sector containing the targeted data into internal memory, integrate the new data into the previously existing data and then rewrite the entire 4,096-byte sector onto the disk media. This operation, known as read-modify-write (RMW), can require additional revolution of the magnetic disks, resulting in a perceptible performance impact to the system user Most of the OSes correctly align the advanced format sectors.
