Arrived within days of ordering. Setup was simple Added the drives and setup Raid 5. Added another drive without issue. Most affordable I found on the market.
2.5gb port, expandable RAM, HDMI out, expandable upto 32TB
Easy to install.
Unit comes with 8 mb of RAM. Upgrading to 32 was easy and allowed use of the more advanced QTS Hero software.
Easy to set-up
Set up is easy, web based interface is convenient and doesnt require drivers or custom apps to be installed, tons of extras like Docker and other integrated applications.
This was ridiculously easy to set up. Just install the drives in the screw-less carriers, plug them into the chassis, connect the eSATA cable and power up. The system sees all the new drives and displays the expansion chassis and drives in the GUI. Then you just choose how you want it setup (RAID5, RAID6 etc.) and the system does the rest. It builds the RAID and optimizes the RAID and filesystem. If you have SSD cache you can even split it between the main chassis array and the expansion array. I had two each 1TB SSDs (too large) and spilt the capacity between the two volumes. Once the RAID was complete I ran ATTO benchmarks on the both volumes and witnessed almost identical performance to both volumes. No performance penalty on the expansion chassis whatsoever. Also, the drives ran cool during all functions. I saw a maximum of 102 degrees F . I was concerned about the performance of the expansion chassis but no need for the concern. You can simply expand your primary volume across the two chassis but I would not recommend that. Separate volumes on each chassis is safer. I would recommend this expansion chassis to anyone wanting to expand their storage with a Synology NAS that supports the expansion chassis. It just works like it should and you can manage all your NAS storage through a single interface. I have the primary NAS connected via a bonded pair of GigE and can saturate both links and see around 220 MB/sec read or write sustained.
I really like all the upgrade options the AS6706T has, especially the M.2 SSDs & Memory.
Happy to have 6 gb total all working ; didnt want to take a risk to go above 6 gb that isnt on the compatibility list
