Ask HN: Should SSDs be accessed like a filesystem or a memory?

Macbook Air SSD memory sticks look just like DRAM sticks to me (see link), but they use a different abstraction to access them (SATA vs. DDR). Are the requirements that drove the original use of ATA still applicable with the SSD memory form-factor (e.g., seek times, etc.)?

Despite looking like memory, SSDs are not much like DRAM. They are also not much like disks either. I suspect you will see new protocols for accessing them eventually, similar to NCQ on SATA drives.

Right. For one thing, SATA (serialized ATA) was originally developed because the disk drive was located away from the motherboard, so I could see this interface looking more like a DDR.

How about other factors, like seek time?
