• Writes over itself (corrupting the first 8GB).
• Enters an endless write loop (seems to copy, but data is garbage).
• Causes the drive to disconnect/reconnect.

offers several features that make it a robust choice for consumer electronics: The Ultimate Guide to the SMI SM3271AC1: Mastering

• The Benefit: This theoretically doubles the write speed. A NAND die that writes at 5 MB/s can achieve 10 MB/s in dual-channel mode.
• The Cost: It requires two physical NAND chips (or one chip with two dies internally) and specific firmware (often labeled SM3271AC1 ISP).
