So to confirm, can you tell us what read and write speeds you get in MB/s. Quick question, is it possible to run Hardware Raid1 on the parity and/or cache drive? Specifically the cache drive is what I am interested in since if you want good (or in my opinion acceptable) write performance then you need to use a cache drive. Only, this simply delays the real write including parity as it defer it to a later time (3am ish is default server setup time I believe).

If the cache drive fails before this defered write has completed, then the data is 100% lost and irrecoverable. So there is a trade off as to how big a cache drive you use and how often you write the defered writes fully. This is a cause for concern for me, but I was wondering it there is any reason that you could not utilize a hardware Raid1 setup for a pair of mirrored disks, of which Unraid simply sees one disk for still for the cache drive. Otherwise unRaid certainly presents a great solution for media serving, since it is mainly the read speed which is important in such circumstances. I have been reading up on it as much as possible but have a concern about the licence/cost situation.

As a lot of you may have already grasped, there IS a cost associated with using unRaid. There is no way around this cost because the licence key you get given to use the software is tied to your USB/Flash drives GUID.

The software/OS is designed to run on a USB or flash drive. The GUID is basically a hardware serial number/identifier. You install the trial version of unRaid first and then use the management tools to extract your USB sticks GUID and send it off to get your licence. For anyone serious about future expandability and a realistic amount of features and allowed number of drives, most people will almost certainly go for the top costing licence as below (which is a lifetime licence one off fee I believe): unRAID Server Pro - $119/$149 - 21 drives (19 data, 1 parity, 1 cache) Now the problem. What happens if you lose your USB key? What happens if it fails or corrupts?

The licence is tied to that piece of hardware. You then have to contact limetech for assistance. The bespoke small company that they are, now are the only people that can help you get your data back.namely, one guy, named Tom. The official response posted on limetechs forums from the Admin there: (I assume this may well be Tom himself) 'This is a common question and our 'unofficial' response has always been this: just email me the circumstances of how your Flash died and the GUID of your new Flash & we'll send you a new key.'

Before I go any further, I will say that people on the forums have had success in contacting him for assistance with this before. But it does seem a major weakness and concern. What if your Data outlives Tom? What if limetech fold? You then have to go out of your way to mount your drives individually in the free version of unraid or a Resier File system compatible Linux distro, let alone pull it all off and start from scratch if you cannot obtain another licence (worst case).
