someone told me......
PCIe is an SSD, PCIe refers to the connection standard. Older SSD's used SATA connections, but the PCIe connection is newer and faster.
so is it worth getting? and is their any errors i should be worried about?
It's totally worth it. PCIe SSDs are far faster than regular SATA3 SSDs.
PCIe is the connection standard. SSD is SSD. There are two types of SSDs currently, SATA3 and PCIe.\
And there's also two types of PCIe SSDs. The ones sold in the market are M.2 NGFF PCIe SSDs, while the ones that Apple uses are non-M.2 proprietary PCIe SSD.
