PNY StorEDGE is a storage expansion card launched by PNY, which is actually a short SD card. It mainly involves expanding the storage space of the MacBook Beggar Edition. Because of its relatively short shape, it is basically invisible after insertion, without affecting the appearance. In contrast, buying PNY StorEDGE to expand is quite good in terms of ease of use and cost performance.

Both capacities of PNY StorEDGE have historically been at a low price, with 64G at US $39.99, about 243 yuan; 128G is 97.95 US dollars, about 600 yuan. The same Taobao model costs 460 yuan and 1200 yuan, respectively. The price advantage is obvious, and this model does not have the pace of the Bank of China.

Note that it seems that Retina 13 "and 2013 Retina 15" cannot be perfectly invisible.
