256MB Internal Memory on Xbox 360 Jasper Arcade

An unexpected bonus is that all Jasper based Xbox 360 Arcade systems come with 256MB of NAND Flash on board:

This internal Memory unit is placed due to NXE memory demand. So this memory can be used for installing NXE into xbox 360 or saving game file, because in xbox jasper already bundle with NXE feature.
But this internal memory also have disadvantage that Arcade systems will no longer ship with external Memory Units, as reported by at least one Jasper hunter. Assuming this is the case, the Arcade SKU is now equipped to handle various memory-required functions like game saves and NXE (128MB) without the use of an external memory device. Of course, this also means the advantages of the once-bundled Memory Unit must be sought at an extra cost. Microsoft has not confirmed the installation of internal memory for other Xbox 360 SKUs nor has it confessed to outfitting its consoles with the Jasper chipset
