ADM 2.1.1.R3B2 firmware was loaded onto a AS-204TE for testing, using the recently introduced Revision 5 NAS test process. The results for products tested with Revision 5 will vary slightly from the results created using Revision 4 and therefore are not directly comparable. Products tested with Revision 5 use a new, dark gray bar as compared to the lighter gray bar used for Revision 4.
Since the AS-202TE uses the same processor, RAM and Ethernet components, all testing was done on the AS-204TE. The AS-204TE tests used four drives configured in single RAID 0, 5 and 10 volumes. The AS-202TE tests used two drives in single RAID 0 and 1 volumes.
ASUSTOR AS-204TE Benchmark Summary
With two drives mounted in the AS-204TE to represent the performance of the AS-202TE, RAID 0 Windows file copy write was about 2% faster than the corresponding RAID 0 write results with 4 drives (77.0 vs. 76.2 MB/s). With just 2 drives, RAID 0 Windows file copy write results were about 6% faster than the RAID 1 write results (77.9 vs. 73.5 MB/s).
For file copy read results, however, the story was reversed. RAID 1 windows file copy read was about 7.6% faster than the corresponding RAID 0 read results (97.4 vs. 90.5 MB/s). As with the AS-204TE NASPT tests, NASPT file copy tests were faster than the Windows file copy tests for write operations, and slower for read operations for both RAID 0 and RAID 1.
ASUSTOR AS-202TE Benchmark Summary
Comparative Performance - Four Bay
Filtering the NAS Ranker for 4 drives and dual core Atom processors you'll see that the ASUSTOR AS-604T, with Total NAS ranking of 11 out of 72, ranks as the top four-bay NAS. Looking down the chart, you'll see that the ASUSTOR AS-204TE comes in fifth of nine total products for the filtered results. From a value perspective, the AS-204TE looks like it's properly positioned, as there are no other less expensive devices with a better (lower) Total NAS ranking.
NAS Ranker for dual core Atom 4 bay NASes
To understand the differences between the $588 AS-604T, its less expensive, somewhat lower-powered $428 AS-204TE sibling,and the $401 Thecus N4560, I created the composite Ranker Performance Summary below. Phrased another way, the detailed performance results help you to understand what you get if you spend the extra $160 to go for the top performing NAS in this filtered view. Or alternatively, what you'd get if you spent $27 less and bought the N4560.
As you can see, the AS-604T blows away the AS-204TE and the N4560 in every sub-category. Most noticeably, the AS-204TE's rankings are dragged down by the relatively poor read and write benchmarks. It ranks #42 for both subcategories. The AS-604T turned in strong performance in all sub-categories with iSCSI results leading the way. iSCSI performance was 96.9 MB/s for Write and 90.0 for Read and ranked #11 and #9 respectively.
Compared to the Thecus N4560, the ASUSTOR AS-204TE ranked lower for the Write benchmarks (#42 vs. #32), the Read benchmarks (#42 vs. #35), and for Video (#29 vs. #16). The AS-204TE outperformed the N4560 for Mixed Read/Write (#16 vs #20), iSCSI (#16 vs. #23), and significantly outranked the N4560 for backup (#24 vs. # 50).
