Tim- I'm weighing redoing my home NAS I'm thinking about either going with FlexRAID or Storage Spaces. Right now it would be two pools, about 30tb each.
I'm just going to demote the old whs and convert it to NAS4free and make it a backup target. I'm somewhat drawn to Flexraids logic of if multiple drives die you can still just pull the disc drives out and read them on another machine. This wouldn't necessarily be true in storage spaces. Just thinking on it. -----Original Message----- From: "Tim Lider" <[email protected]> Sent: 7/3/2013 8:57 AM To: "[email protected]" <[email protected]> Subject: Re: [H] External drives (USB) and power requirements The reason is that the ROM/ROM Modules (Specifically ROM Module 47 (Adaptives)) have information on it that is specific to the HD it is mated to. Some times you can be lucky to get a PCB to work with a HD, but do not run it too long, bad things will happen. What the Adaptives are is information on head weight, voltage needed to spin HD up, voltage needed to for thermal assist metals inside the HD (Gimbal) and the exact spindle rate (7211rpm). There is more, but those are the main issues. Regards, On July 2, 2013 at 4:16 PM Thane Sherrington <[email protected]> wrote: > At 05:49 PM 02/07/2013, Tim Lider wrote: > >You have a point there.
