128k Sequential Read/Write
The 128k sequential speeds reflect the maximum sequential throughput of the HDD using a realistic file size encountered in an enterprise scenario.
The WD Xe cuts across its platter very quickly as evidenced by the seesaw looking performance figures. This effect stems from the heads flying across the whole platter during each test period. The Xe averages 179 MB/s, the Toshiba AL13SE averages 184 MB/s, and the Seagate v7 takes the lead with its average of 195 MB/s.
The WD Xe averages 179 MB/s, the AL13SE 182 MB/s, and the Seagate leads again with 195 MB/s.
The Xe provides solid performance in the mixed read/write testing.
The WD Xe exhibits good consistency in this test, but the Seagate drive delivers lower overall latency.
The WD Xe again delivers a dominating performance in power consumption, drawing a miserly 6.22 watts.
It was not hard to predict the Xe would win the efficiency testing due to its conservative power draw.
