ST500DM002-1BD142 ATA HD - 1-MB Benchmark
What is the 1-MB I/O performance of Seagate ST500DM002-1BD142 ATA HD on Azure VM?
✍: FYIcenter.com
The I/O performance of reading and writing 1-MB files
of a Seagate ST500DM002-1BD142 ATA HD can be
measured by running SQLIO with multiple 1024-KB blocks with a large
stripe factor.
Here is the read performance test of Seagate ST500DM002-1BD142 ATA HD on Azure VM with 1024-KB blocks.
C:\fyicenter\SQLIO>sqlio -LS -kR -b1024 -i64 -f64 -t1 -s30 -p0 1 thread reading for 300 secs from file test.dat using 1024KB IOs over 65536KB stripes with 64 IOs per run affinity on cpu number 0 size of file test.dat needs to be: 4294967296 bytes initialization done CUMULATIVE DATA: throughput metrics: IOs/sec: 59.58 MBs/sec: 59.58 latency metrics: Min_Latency(ms): 9 Avg_Latency(ms): 16 Max_Latency(ms): 354 histogram: ms: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24+ %: 0 0 0 0 0 0 0 0 0 0 0 3 18 11 6 7 8 11 21 5 3 1 1 1 4
Here is the write performance test of Seagate ST500DM002-1BD142 ATA HD on Azure VM on 64-KB blocks.
C:\fyicenter\SQLIO>sqlio -LS -kW -b1024 -i64 -f64 -t1 -s30 1 thread writing for 300 secs to file test.dat using 1024KB IOs over 65536KB stripes with 64 IOs per run affinity on cpu number 0 size of file test.dat needs to be: 4294967296 bytes initialization done CUMULATIVE DATA: throughput metrics: IOs/sec: 72.48 MBs/sec: 72.48 latency metrics: Min_Latency(ms): 4 Avg_Latency(ms): 13 Max_Latency(ms): 211 histogram: ms: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24+ %: 0 0 0 0 0 1 2 2 1 2 8 20 20 18 11 5 2 1 1 2 2 1 1 0 1
Reading/writing speeds of 1-MB blocks, 59.58/72.48 MBs/sec, are much higher than reading/writing speeds of 64-KB blocks, 7.94/33.86 MBs/sec. So Seagate ST500DM002-1BD142 ATA HD is more efficient when reading/writing larger files.
⇒ ST500DM002-1BD142 ATA HD - Maximum Reading Speed
⇐ ST500DM002-1BD142 ATA HD - 64-KB Benchmark
