Hi, I'm looking at the "USB Quad Drive SATA Enclosure Part No. 42825" to extend the capacity of a MS Windows Home Server (based on Win2003). The info on the website states that the chassis will support 4x 1TB disks. Is this a genuine hardware restriction of the box or just a practical limit of the expected operating systems?

e.g. what actually happens if I put one or more 1.5TB drives in, configured to appear as individual drives?. The OS is more than capable of seeing and formatting these...

Many thanks from a long-term customer,

Barry.

Hi Barry,

Sorry for the delay in response its very busy after the Easter holidays

As you mention, the OS can sometimes be a limiting factor when trying to use one big disk.
Looking at this Microsoft forum post here it seems that WHS can only handle 2TB as a maximum disk size?

You should be able to get around this with an external drive which combines the disks, I guess this is why you are asking the question ;)

I'll ask our factory now to confirm the maximum size, as I see no reason why it won't go over 2TB when spanned across multiple disks.

Best Regards

Our factory have confirmed that the maximum supported (Tested) drive is 4x 1TB.

Which would obviously give a maximum disk size of 4TB (If set that way)

Best Regards

Hi Chris,

Thanks for the reply and the research too. I don't know if you've looked into the way that Home Server (WHS) handles storage disks but it's quite clever. The user interface allows you to add individual drives to a pool so, in effect, it provides spanning of individual drives natively without needing specialist hardware. The next step is to create a network share and decide if you want folder duplication or not.
If you say yes to folder duplication, it makes sure everything stored on that share is stored to two separate disks, so if a (single) disk is lost, the files aren't. It's not the same as RAID1 though as it isn't just simple disk mirroring.

The other clever feature is that, if you need to remove a drive from the pool, the interface will tell you what it needs to do to achieve this, e.g. if it is managing files on a duplicated share, it will have to move them to another (second) disk to maintain duplication. The same with non-duped files, these will be moved to another disk. If WHS can do this, it'll do the work for you, if you don't have the space/disks to do this, it'll tell you what you'll lose.

For these reasons, I'd be quite happy to see each drive in the box individually and let WHS manage how they're used. I just wondered if anyone had tried disks larger than 1TB in this config. I appreciate that the factory will only support configs that they have actually tested (I'm a software developer for a big company so do exactly the same thing), I just wondered if there was anybody who'd actually tried it and how they got on...

Cheers, Barry.

Thanks Barry,

To be honest I've never had a chance to play with WHS, it does sound very good though !

I would test it for you however I'm afraid we don't have a drive bigger than 1TB at the moment.

We don't often get feedback from customers in regards to problems like these either (Hence why we opened the forum :D )

I'm sorry I can't be of more use, I'd love to say it would work....

Best Regards
