- riazrizvi 2y agoNo this is caching with SSDs, it's not the same league.
- btown 2y agoWith hardware where power-off is only controlled by software, battery life is predictable, and large amounts of data like raw video are being persisted, they might have a very aggressive version of page caching, and a large amount of storage may imply that a scale-up of RAM would be necessary to keep all the data juggling on a happy path. That said, there’s no non-business reasons why they couldn’t extend that large RAM to smaller storage systems as well.
- marshray 2y agoPeople without the "large amount of storage model" need to record video from the camera too. The justifications I see are to reduce the number of models needed to stock and to keep the purchasing decision simple for customers. These are very good reasons.
- astrange 2y agoIt's unified memory which means the SSD controller is also using the system memory. So more flash needs more memory.
