We're talking about interface standards here, not form factors. SATA |
| 5 |
drives use the good old SATA interface and for all intents and purposes |
| 6 |
look just like HDDs to the BIOS and OS. |
| 7 |
NVMe drives have an onboard controller that attaches directly to the PCI |
| 8 |
express bus and use a completely different programming model for access. |

Most consumer-grade 2.5" SSDs (those that "mount like HDDs") are SATA, |
| 11 |
while board-mounted M.2 ("gumstick") drives can be either SATA or NVMe, |
| 12 |
as the M.2 connector supports both standards. |
| 13 |
|
| 14 |
If you have no M.2 connectors, you're safely stuck with SATA drives. |

"NAND flash" (as opposed to "NOR flash") refers to the way memory cells |
| 21 |
are organized and connected. See for example |

AFAIK all SSDs use some variant of NAND flash. |
