QNAP TS-419P+The QNAP TS-419P+ has been added to the NAS Charts.

The TS-419P+ is a quad-drive version of its new one and two bay 1.6 GHz Marvell Kirkwood based NASes that I've recently tested.

It shares all of the features of its siblings and adds RAID 5, 5+ spare and 6 volume support.



The 419P+ is surprisingly quiet for a four-bay NAS, even a bit quieter than the TS-219P+. Once the system finished booting, fan noise was negligible and drive noise dominated, but was muted.

Power consumption measured 36 W with the four 1 TB SAMSUNG Spinpoint F3 HE103SJ 3.5" SATA drives QNAP loaded into the review sample spinning and a low 16 W with the drives spun down after a programmable idle period.

Tests were run with recently-released 3.3.9 Build 0105T updated firmware using our latest test process. The Benchmark summary below gathers all the test results into one place for easy reference.

QNAP TS-419P+ Benchmark Summary

QNAP TS-419P+ Benchmark Summary

Windows File copy write for a RAID 5 volume measured 47 MB/s and read came in at 95 MB/s. RAID 0 file copy write of 66 MB/s and read of 86 MB/s showed that the Kirkwood processor is a bit underpowered to handle RAID 5's extra overhead.

NASPT File Copy writes were higher than the Windows file copies at 86 and 62 MB/s for RAID 0 and 5, respectively. NASPT File Copy reads were lower, coming in at 76 and 71 MB/s for RAID 0 and 5.

The tougher NASPT Directory Copy tests yielded speeds in the mid-teen MB/s for write and read of RAID 0 and 5 volumes.

Like the other P+ NASes, the 419P+ was not able to complete all NASPT tests, so the Office Productivity results in the Benchmark summary are once again missing. Failure to complete all tests can be due to write cacheing, oplocks or simultaneous connection limits baked into the NAS OS and usually occur in one of the NASPT tests that reads and writes multiple folders of small to medium sized files.

Backup speed to an attached USB drive basically maxed out the bus at 25 - 26 MB/s for FAT, NTFS and EXT3 formatted attached drives. Switching to an eSATA connection to our standard Iomega UltraMax Pro configured in RAID 0 yielded speedier results of 69 MB/s for FAT, EXT3 and 58 MB/s for NTFS.

Rsync network backup to the NAS testbed running Delta Copy produced 26 MB/s, similar to attached USB drive speeds.

iSCSI write and read to a 10 GB target on a RAID 5 volume produced 38 MB/s and 57 MB/s, respectively.

For competitive comparison, check the RAID 5 File Copy Write and Read charts below, filtered for four-drive NASes. As expected, the 419P+ generally can't match dual-core Atom-based competitors like QNAP's TS-459 Pro+ or Synology's DS411+. In fact, there aren't any other four-bay 1.6 GHz Kirkwood powered NASes currently in the charts to directly compare against.

The 419P+ is much more competitive on reads, only slightly behind the D410 Atom based QNAP TS-439 Pro II.

File Copy Read Comparison - four bay NASes

It seems odd to have a typically premium-priced NETGEAR be a good competitive alternative. But the driveless ReadyNAS Ultra4 (RNDU4000) with a D410 Atom and 1 GB of RAM is actually pretty good at essentially the same price.

QNAP's V3.3 OS feature set is covered in the recent review, so there is no full review planned for the TS-419P+. Please use the NAS Charts to further explore and compare the TS-419P+' performance.
