This means 4 can be mounted on a 1-wide 12.5' long PCIe card if some vendor wants to do it. A 2.5' form factor has a 2.76 x 4 inch footprint. Apple's Mac Pro looks like it can hold 5' tall cards, at least. 15 mm can probably fit too, but it will be tight.Ī full length PCIe card is 12.5'. A 10 mm or less thick 2.5' drive will fit in a 1-wide PCIe card, as the picture shows. The thing with the Mac Pro is that it is much less height constrained for PCIe cards than 'normal' PCIe cards. It's an optical illusion that it doesn't look like the red SATA cable plugs?Īs for mounting 2.5' form factor drives on PCIe cards, they are of course on the market.
However, I have seen cards that support four M.2 drives, though. The 2.5-inch drive height pretty much precludes a single-wide PCI-E card with four 2.5-inch drives, but I can't say for sure that there are none. That is a fairly standard USB 3.0 to SATA cable. There aren't any single wide PCIe cards that can hold 4 2.5' drives? What's with the crazy plug on the drive end? Wow, the 3rd drive uses the internal USB port.
