5 out of 5 eggsGet it! You won't be sorry

Pros: AMAZING!!!. This thing does everything except maybe your pancakes for breakfast. Nearly silent, small footprint, runs cool, feature packed. Interface is very intuitive. I love it! I run it as FTP to do nightly (CRON via cPanel) backups of all my websites. Serves as my media server and desktop backup server for now. So many more options to still explore and implement. I have it packed with 4x320 WD Blacks and 4x500GB WD Blacks setup as 2 RAID-6 arrays. I can experience loss of 2 drives per array and still not loose data, you've got to love that. Totally love the form factor and very low energy usage.

Cons: None I can see.

Other Thoughts: Don't be stupid and order 3.5" drives with this. This unit requires 2.5 SATA drives (laptop sized). I only buy drives that are 7200 RPM, don't waste money on anything slower. If you need lots of Terabytes than go with unit that supports 3.5" drives that are 3TB each if that is what you need. Synology DS1511+ here on NewEgg is a great unit with great reviews. I just wanted the 2.5" drive form factor. (think lowwww power usage, no heat)

Make sure the first thing you do is update to the latest firmware/software available from QNAP. A lot more features available with the new software, even the manual tripled in size to cover all additional stuff.

5 out of 5 eggsQNAP ss-839-pro Great Buy!

Pros: It was very easy to install and configure, it has nice web interface. I was able to set mine up with RAID 5 and get it up and running in about 30 minutes. Software update works very nicely and features are excellent. I had the device for almost a year without any failures.

Cons: Price.

Other Thoughts: It does not come with disks for all you people who never read the details.
It is VERY quiet and keeps very cool. Uses 2.5 in drives

4 out of 5 eggsGreat product, not-so-great shipping

Pros: This is an excellent product for the money. If you are looking for a great small-business or home office NAS device, this is the one. High-powered and packed with features including iSCSI. Excellent web-based GUI for management with slick interface. Pros based on replacement unit (see Cons section).

Cons: First unit would not power on when initially hooked up. Very disappointed. Returned and got another one.

Other Thoughts: I am very unhappy with the shipping of this product. It arrived on my doorstep looking like it had just been pulled off of a store shelf, had a UPS label slapped on it and shipped. Anyone could know what the item was which is unacceptable.

5 out of 5 eggsWarning: 2.5" SATA disks required

Pros: See other thoughts - watch disk size

Cons: See other thoughts - watch disk size

Other Thoughts: Looks like a great device. However the specs page on NewEgg didn't indicate that this NAS requires 2.5" SATA drives. Needless to say the 3.5" SATA drives I ordered with the unit didn't fit. I'm returning it and purchasing a QNAP device that will go with the drives I ordered.
