Summary: Put in 2TB hard drives and run in RAID 10, so 3.86TB Right now on firmware 3.83 as of 5/19/2014 It is OK, I have a all MAC home, 3 iMac, Macbook, Macbook Pro, Fujitsu S1500M scanner...... use it for storage and it's ok one iMac as a time machine backup but it is TEMPERAMENTAL.....
Summary: I have purchased my QNAP NAS (419-PII) with brand new hard drives. Ever since it was first installed, I had to rebuild the RAID5 several times, even though all drives were working fine and all internal drive tests (SMART, bad blocks...) always approved all Seagate drives.
Summary: I used this product to replace a massive dell server configured in a RAID 5 setup for file storage. This blows it away for speed and has vastly improved network file retrieval and storage space. Its been a few months and I am still impressed.
VMWARE & iSCSI feature set is incomplete / poor support

Summary: I find the product lacking in its redundancy feature set and customer support. This comes from first hand experience during the failure of a drive in the QNAP TS-879U-RP, 8 drive product, in January 2013. I am writing to update this review in May 2013. My issues are not solved.
Summary: I would love to go into great detail on this QNAP, but I don't have much time right now... I do really want to sit down and go over the entire OS and the great features. For now, here are the 2 best features: 1) Amazon S3 backup. This has a built in software to connect to S3.
Summary: The eSATA ports on this unit is for adding on additional storage devices only. You can't connect this NAS directly to a PC via eSATA as an external drive. It has to go through gigabit, so read and write speed is limited by gigabit's limit. Dual gigabit helps but direct eSATA is still WAY faster.
