Drive Sizing - How Large Primary Drive? RRS feed

  • Question

  • I have had the opportunity to read many of the posts here as well as the technical documentation and still have a questions.

     

    I have noted in the posts and the Microsoft documentation that you should install your largest drive as the primary drive.  Here is the scenario I would like to explore.

     

    3 Drive system, either 3-1 TB drives or alternately 2-1TB drives and 1-500GB Drive.

     

    My thinking at this point is that I could save some money (about $180) by going with scenario 2 and installing the 500GB drive as the primary.  The reason that I think this is that the documentation states that in a system where there are at least 1 primary and 2 secondary storage devices, that drive extender always stores the actual file and any shadow (duplicate folder) copy of the file on the secondary devices, leaving only the tombstone on the primary data drive.

     

    If this is true, I envision all of of the files on the two TB drives and gobs of 4K tombstones on the primary drive.  If even only 450GB remained on the primary drive after the server partition and formatting of the drive, that would leave room for over 112 Million tombstones.

     

    I also realize that the size of any individual file copy is limited to the available space on the primary data partition, that the size of the files I would be able to copy would go down as the number of tombstones went up.  But still, I could have 55 Million tombstones and still have about 225GB free on the primary.

     

    I just hate to waste expensive drive space on the primary if it will never be used!

     

    Any comments will be appreciated!

  • Yes, that should work fine. The only time the size of the system disk becomes a factor is when you're copying large numbers of files, large files, or when your server is so close to full that it's putting files on the primary disk.

  • There may be an important reason why you might consider a large primary drive - particularly if you will be tranfering large files to the WHS.  See a post from a different section by a moderator below:

    Answer Re: Slow transfer speed when copying large files to WHS
    Was this post helpful ?

    How big is the first hard drive in your home server?  Windows Home Server uses 10 GB of the primary hard drive for the operating system and the remainder is used for the first DATA volume.   This first DATA volume is used for copying data from PCs to your home server and then Drive Extender will move it to one of your other hard drives. 

    Also, if Folder Duplication is turned on for one or more of the given shared folders then Drive Extender will make sure there are 2 copies of each file stored on 2 separate hard drives.   And lastly, if you have enable "Media Library Sharing" on the Photos, Music and/or Videos folder, then Windows Home Server will start indexing the media as it is added to these folders.

    If you want to copy lots of data to your home server - here are a few recommendations:

    • Have a large primary hard drive - I have a 300 GB drive in my home server
    • Turn off 'Folder Duplication' on a shared folder during a big copy operation and turn it back on after the copy completes
    • Turn off "Media Library Sharing" on a shared folder and turn in back on after the copy completes.

  • Hi,

    Earlier in the beta, there was considerable discussion regarding this particular issue and the consensus then, appeared to be around 350 to 400GB. This was based on the size being about the 'sweet spot' for price and power consumption. It had the benefit of providing a reasonable 'landing stage' for file transfer which might be a little restrictive initially when first used, but subsequently, provide more than enough for regular day to day use.

  • Thanks Coln!

     

    So in conclusion, you would say that my second scenario of 1-500GB drive for the primary and the 2-1TB as secondarys should work fine, Correct?

     

    Thanks!
