Because the drive does not contain movable parts, it's quite easy to open and check it out. You should not do that, because it will invalidate the warranty. Sorry for the low quality pictures.
The heart of the drive is the Indelix Barefoot Eco controller which is common in most drives. The new revision is able to handle the newly introduced 34nm flash-chips.
The drive also has a 64MB cache chip which runs with just 166MHz.
The drive contains eight 32Gb chips. Normally you could get 64GB, but as any hard drive it's calculated with 1000 instead of 1024, so the drive reports just 61057MB. The spare space is used for bad cells. GSkill does test each chip, that's why they are numbered and they did not mix up different batches.
Here a close look to the Intel 34nm NAND MLC chip:
