[NAME], That's not really what it says.  It says: "This section lists the storage options on your G5 5000." As in, the options that Dell offers for that machine.  Not what it can handle after-the-fact.  The size limit is actually imposed by Windows, and it really doesn't have one anymore.  Adding in a 4 TB drive shouldn't be a problem. 
Hi all, I would like to add a 4TB or 5TB 3.5" SATA hard drive.  The manual and tech support said that the desktop only supports up to 2TB?   Would it not work or be recognized by the BIOS?  I mean 4TB hard drives have been around since 2011;  is Dell really that behind the times?   I really need the storage space for photography and video editing.  Would appreciate any help.  Thanks in advance.
