For the purpose of NAS reviews, we have setup a dedicated testbed with the configuration as below. The NAS is directly connected to the testbed (using as many Cat 5E cables as there are ports on the NAS) without a switch or router inbetween. This is done in order to minimize the number of external factors which might influence the performance of the system.

NAS Benchmarking Testbed Setup
Processor Intel i5-680 CPU - 3.60GHz, 4MB Cache
Motherboard Asus P7H55D-M EVO
OS Hard Drive Seagate Barracuda XT 2 TB
Secondary Drive Kingston SSDNow 128GB
Memory G.SKILL ECO Series 2GB (1 x 2GB) SDRAM DDR3 1333 (PC3 10666) F3-10666CL7D-4GBECO CAS 7-7-7-21
PCI-E Slot Quad-Port GbE Intel ESA-I340
Optical Drives ASUS 8X Blu-ray Drive Model BC-08B1ST
Case Antec VERIS Fusion Remote Max
Power Supply Antec TruePower New TP-550 550W
Operating System Windows 7 Ultimate x64
.

In addition to the Realtek GbE NIC on-board the Asus P7H55D-M EVO, four more GbE ports are enabled on the system, thanks to the Intel ESA-I340 quad port GbE ethernet server adapter . With a PCI-E x4 connector, the card was plugged into the PCI-E x16 slot on the Asus motherboard.

Two of the four ports are teamed together as shown in the video below below during the benchmarking.

Intel NASPT is used to benchmark the NAS device. In order to ensure that the hard disk transfer rate is not a bottleneck, NASPT is run from the secondary drive in the testbed (the Kingston SSD). With average read and write speeds of 178.8 MB/s and 167.8 MB/s, it is unlikely that a single GbE link NAS can be limited in performance due to the test system. However, a link aggregated NAS could be affected. Fortunately, as we will see in the next few sections, this wasn't the case for the TS-659 Pro II.

All file copy tests were also performed using the SSD. The file copy test consists of transferring a 10.7 GB Blu-Ray folder structure between the NAS and the testbed using the robocopy command in mirror mode.

There are three important sharing protocols we investigated in the course of our evaluation of the TS-659 Pro II. In the next few sections, you will find NASPT / robocopy benchmarking results for Samba, NFS and iSCSI sharing protocols. Each section also has a small description of how the shares were set up on the NAS. The NASPT benchmarks were run in Batch mode thrice, giving us 15 distinct data points. The average of these 15 values is recorded in the graphs presented in the following sections. The robocopy benchmark was run thrice, and the average transfer rate of the three iterations is presented alongside the NASPT benchmarks.

The TS-659 Pro II supports multiple RAID configurations, but we believe that most of the users will end up running this in RAID-5. So, all our benchmarks are collected with the disks configured in a RAID-5 volume. The GbE ports were configured for dynamic link aggregation (802.3ad) as shown below:

Note that the 6 x 1 TB disks result in a total available space of arund 4600 GiB (shows up as GB on the NAS configuration webpage) when configured in RAID-5. This is due to a couple of maintenance partitions created by the QNAP firmware. Each 1 TB disk is partitioned as below.

    Hey! I just wanted to post a quick comment regarding this:
    "The redundancy helps in data recovery, in case of media failure of any other unforeseen circumstances."
    Really, RAID only helps in case of a media failure. Most other "unforeseen circumstances" (which btw really aren't unforeseen...) cannot be helped by a RAID:
    - unintentional deletion of a file
    - virus
    - power black out
    - mainboard/PSU failure which fries the system

    There are a lot of things that a RAID can do nothing about and need to be taken care of separately. I'm sure you know that, but the statement above made it sound differently. :-)

    Better to have data on two separate machines running no RAID than on one machine running RAID if data backup is your goal. RAID was designed primarily for enterprise use to minimize downtime when a drive fails - and even then, any serious business will have an offsite backup. In home use, the time-cost for replacing the hard drive on a non-RAIDed machine and then copying data from your backup machine is well worth the data safety you get from having that backup machine.

    That said, external AND internal hard drives are both *relatively* cheap, so should be not-too-hard to get the benefits of both RAID and backup in home use :)

    I agree with your points :) But, the mainboard / PSU failure doesn't mean that data is lost. Please check out my LG N2A2 review, where I recovered data from a 'fried' system using UFS Explorer.

    I believe UFS Explorer can still be used here, but one needs to feed each disk into the rebuilding computer, make an image, and then recover after making UFS Explorer recognize all the images. I didn't check this out because I don't have a test system handy with ~6 TB worth of free space. Will try to redress in future :)

    MoBo/PSU failure might easily take the disks with itself either by corrupting data or physicaly damaging them.

    Not to mention no way ofe getting them back withou getting identical mobo even if data was not touched AND hoping the new firmware will not zero them on sight ...

    True!!! But data storage and backup are two different things. As the article states RAID helps with media falure.

    Just need to correct this
    » unintentional deletion of a file - QNAP has a network recycle bin, so if you do delete a file it is not deleted. Only the soft link is deleted until you empty the recycle bin.
    » virus - QNAP has an addon AntiVirus product, but then you should use Access Control Lists to protect data from virus and deletions.
    » Power Black Out - Anyone that has a NAS, and does not have a UPS attached is a fool!!
    » mainboard/PSU failure which fries the system - Use a UPS which has a clean line filter so the main board does not get a spike, even if it did fry the system. QNAP uses a software RAID so pull it out and put in another QNAP and re-apply the firmware and you are up and running again.

    I agree though.. RAID is RAID it is not data protection (too a point) it is physical media protection for the RAID volume if a hard drive fails. That being said, there is nothing stopping you from making a 4 bay RAID 5 and then having a 1 or 2 bay RAID 0 on the same box for backup.

    I have a TS-859 Pro + for personal use, I have a 5 Bay RAID 5 which is backed up onto the same QNAP which has 2 Bays holding 2 x 3TB drives in a RAID 0 for backup.

    Oh.. forgot to also state, I then backup my box to another rsync server located at my brothers house through a VPN. Additionally I backup data to a cloud service for highly important stuff (photos), all of which the QNAP OS supports. Reply

    All your points are very valid, as well. :D
    But the article made it sound as though just having the redundancy is all you need. That was my main beef, as such a statement might lead the uninformed to set up a RAID array, put all their beloved old childhood photos and videos on it and then be surprise when there is a power outage which messes up all their data.

    Yes, you can protect against black out, electrical spikes, viruses, unintentional deletion etc. But by other means than a RAID.
    That was my point. Not that RAID is inherently dangerous. But that such a broadly worded statement is false and can lead uninformed people into dangerous situations. A brief 2 - 3 sentence paragraph about this stuff would suffice to enlighten most people to the problem, I think. :D

    RAID is good (except RAID 0), the article does state it protects against media failure, meaning the physical disk. With the size of Hard Drives increasing any NAS in a RAID is a good choice, keep your data off your desktop or laptop, how many times have I seen people loose all the family photos due to a Drive Fault, this alone is a good reason to buy a NAS.

    However you shoud be Paranoid about your Data, back it up and store it out of your house. Its all good having a 6 Bay unit filled with 3TB drives, but then how do you back that data up... another NAS or rsync server.

    You should always think that someone will break in and steal your NAS, or even fire or flood.

    I have two QNAP;s as well 809's.
    photobucket.com/albums/xx165/goldcoin1/P9200347.jpg

    for those who do not know the three latest firmwares have been 3.3 , 3.4 , and 3.5 In 3.4 they implemented RAID 10 capability.

    Details of the firmware updates below.

    3.3> http://www.qnap.com/fw_v3/

    3.4> http://www.qnap.com/fw_v34/Default.aspx?lang=eng

    3.5> http://www.qnap.com/fw_v35/features.asp

    IMO QNAP is the way to go.
