Add a Memory Card

Next to processor speed, the most significant factor in the performance of any computer is memory. Given that every design decision on Treo devices must be carefully weighed against size, cost, weight, and ruggedness, it stands to reason that memory is the biggest Treo bottleneck. As pointed out in “Understanding the Treo 650 Memory System” in Chapter 1, “Meet Your Treo,” the Treo 650 has an even more pronounced memory bottleneck than the Treo 600 because of its shift to the Non-Volatile File System (NVFS) memory system, which is considerably less efficient than its predecessor.

If you use desktop computers as a comparison for smartphones such as the Treo, it might seem strange that the Treo has such a memory issue. The problem has to do with the cost of compact memory, which is higher than the cost of desktop or even notebook memory and incredibly higher than the cost of hard drives. The comparison to hard drives is important because handheld devices, especially mobile phones, typically don't have hard drives, so they must rely on some form of memory as residual storage. When you look at trying to replace the storage space of a hard drive with memory, cost suddenly becomes a big problem.
