Conclusion The Netgear ReadyDATA 516 is a 6-bay desktop form factor NAS that provides hot-swappable drive bays that accept 2.5" and 3.5" SATA HDDs and SSDs up to 4TB for a maximum total of 24TB raw capacity and can support multiple RAID 0, 1, 5, 6, 10, 50, 60 volumes. As far as performance specifications go, the ReadyDATA 516 offers 16GB ECC Memory and features an Intel Core i3 Ivy Bridge 3.3GHz Processor. The Netgear NAS also ships with two 10/100/1000 Ethernet ports, one USB 2.0, two USB 3.0 and three eSATA Ports. Additionally, the ReadyDATA 516 offers both a read and write cache options via optional SSDs, a unique feature among its class. Measuring performance for our benchmark tests, we implemented RAID10 configuration utilizing iSCSI and SMB with R/W Cached, Read Cached, and Uncached setups. When we look at throughput, the top performer for 4k, 8k and 128k was the ReadyDATA 516 R/W Cached iSCSI throughout the entirety of the tests in the write column. In the 4k activity throughput, the Netgear ReadyDATA 516 was able to pump out 586 IOPS write and 3307 IOPS read from the top performer. In 8k testing, the ReadyDATA 516 R/W Cached iSCSI delivered over 51,388 IOPS for write activity while the Read Cached iSCSI protocol reached over 28,611 IOPS. For 128k, the ReadyDATA 516’s throughput was once again very good, ranging as high as 231,357KB/s for write activity and 461,138KB/s for read activity. In terms of latency performance, there wasn't really a clear winner. The 4k and 8k average latency proved a stronger area for the Cached iSCSI; however, the 4k and 8k max figures leaned strongly in favor of the SMB Cached protocols. In 4k standard deviation, both the Cached SMB and iSCSI were solid in read and write activity, while the ReadyDATA 516 R/W Cached SMB was the top performer by the 16T/16Q. The ReadyDATA 516 is a worthy addition to Netgear’s smaller NAS line with the performance numbers to back it up as well as a hefty five-year warranty and an easy interface that makes setup and management an easy process. It isn’t cheap, however, going for roughly $1300 USD at most online retailers; though that price is to be expected based on what it offers. Leveraging ZFS, Netgear is able to offer compression, dedupe, and snapshots and with the caching layered on top they were able to negate many of the performance limitations we've seen with ZFS-based platforms in the past. If your a small business looking for a powerful desktop form factor NAS, the Netgear ReadyDATA 516 is definitely worth looking into.
