INTEL SSDPEKKF256G8L SSD - 1-MB Benchmark
What is the 1-MB I/O performance of Seagate INTEL SSDPEKKF256G8L SSD on Azure VM?
✍: FYIcenter.com
The I/O performance of reading and writing 1-MB files
of a Seagate INTEL SSDPEKKF256G8L SSD can be
measured by running SQLIO with multiple 1024-KB blocks with a large
stripe factor.
Here is the read performance test of Seagate INTEL SSDPEKKF256G8L SSD on Azure VM with 1024-KB blocks.
C:\fyicenter\SQLIO>sqlio -LS -kR -b1024 -i64 -f64 -t1 -s60 -p0 1 thread reading for 60 secs from file c:test.dat using 1024KB IOs over 65536KB stripes with 64 IOs per run affinity on cpu number 0 size of file c:test.dat needs to be: 4294967296 bytes current file size: 0 bytes need to expand by: 4294967296 bytes expanding c:test.dat ... done. initialization done CUMULATIVE DATA: throughput metrics: IOs/sec: 1056.59 MBs/sec: 1056.59 latency metrics: Min_Latency(ms): 0 Avg_Latency(ms): 0 Max_Latency(ms): 11 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+ %: 59 40 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
Here is the write performance test of Seagate INTEL SSDPEKKF256G8L SSD on Azure VM on 64-KB blocks.
C:\fyicenter\SQLIO>sqlio -LS -kW -b1024 -i64 -f64 -t1 -s60 1 thread writing for 60 secs to file c:test.dat using 1024KB IOs over 65536KB stripes with 64 IOs per run affinity on cpu number 0 initialization done CUMULATIVE DATA: throughput metrics: IOs/sec: 498.81 MBs/sec: 498.81 latency metrics: Min_Latency(ms): 0 Avg_Latency(ms): 1 Max_Latency(ms): 70 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+ %: 38 27 18 4 1 9 2 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
Reading/writing speeds of 1-MB blocks, 1056.59/498.81 MBs/sec, are much higher than reading/writing speeds of 64-KB blocks, 243.97/612.38 MBs/sec. So Seagate INTEL SSDPEKKF256G8L SSD is more efficient when reading/writing larger files.
