I picture it as something like an 8-track player but I've never actually seen such hardware. Yes, I remember hearing of that kind of setup, but elsewhere. I've got an old Dell PowerEdge 2900 that has 8 hard drives in RAID (I use RAID 1). Each drive is mounted in a caddy that can be hot-swapped from the front. The caddies are just slightly larger than a 3.5" HDD, and about an inch deeper. Unfortunately, this machine runs these eight drives only in RAID, so that precludes software testing by swapping a drive. The operating system lives on an interior drive (or two) in a more conventional mounting, cabled to the motherboard's SATA port. (This is hulking beast of a machine, measuring 9" wide, 19" high, and 29" deep. I have no idea of it's weight- the last time I picked up, I removed the 8 HDD's and 2 power supplies.) Personally I change hardware very rarely, so I don't need any special convenience. Most of us use VM for those things, I guess... -- Ken Hart |

M Coolermaster CM690 II case has what they called an X Bay built into the top It is a slanted ramp with SSD connectors at the lower end It is a hot Swap bay and you can plug or unplug SSDs at any time. I have about 5 12 GB samsung and Kingston SSDs on which I have installed Windows 10 insider Windows 7 Linux Mint MX Linux ZenialPup 7.5 So I just slide in whatever OS I want and boot into that drive. Best thing since sliced bread, They still make that case 10 years later but sadly have not retained that feature. Rene Sorry, 120 GB SSDs, Pretty hard to find 12 GB ones.Â* :-) Rene Spoke wrong, on looking at that case again apparently they brought the X bay feature Back, they renamed it CM690 II advanced or CM692 USB3 depending where you look They also have a White version.

Although I also replaced the disk because I knew it would fail sooner or later. Cases are not caddies. The frame has a PCB with an IDE & Molex port on the outside for connection to the PC. On the inside is a male IDE connector but no Molex. There are also wires which go to two LEDs on the front (power & activity presumably). The removable tray has a female IDE mounted on a PCB which goes to a short ribbon cable & molex connector for the HDD. Looks like the power is supplied through the PCB IDE ports rather than the wiring being Molex all the way through. The tray also has a small cooling fan at the front. -- Regards wasbit |

On checking there are Molex connectors at both ends but not in the middle so it looks like the power is routed via the IDE connectors. -- Regards wasbit |

Mea culpa. that would have been clearer. there are reasons to have a raid 1 with more than two drives, however, it's not common and i've never seen more than 4. |
