SanDisk Cruzer Blade Flash Drive - 64-KB Benchmark
What is the average I/O performance of SanDisk Cruzer Blade 32GB Flash Drive?
✍: FYIcenter.com
The average I/O performance of a flash drive can be measured by running SQLIO with multiple 64-KB blocks with a large stripe factor.
Here is the read performance test of SanDisk Cruzer Blade 32GB Flash Drive on 64-KB blocks.
C:\fyicenter\SQLIO>sqlio -LS -kR -b64 -i64 -f64 -t1 -s60 -p0 E:\test.dat using system counter for latency timings, 2343896 counts per second 1 thread reading for 60 secs from file D:\test.dat using 64KB IOs over 4096KB stripes with 64 IOs per run affinity on cpu number 0 initialization done CUMULATIVE DATA: throughput metrics: IOs/sec: 239.37 MBs/sec: 14.96 latency metrics: Min_Latency(ms): 3 Avg_Latency(ms): 3 Max_Latency(ms): 15 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 38 61 1 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 SanDisk Cruzer Blade 32GB Flash Drive on 64-KB blocks.
C:\fyicenter\SQLIO>sqlio -LS -kW -b64 -i64 -f64 -t1 -s60 -p0 E:\test.dat using system counter for latency timings, 2343896 counts per second 1 thread writing for 60 secs to file D:\test.dat using 64KB IOs over 4096KB stripes with 64 IOs per run affinity on cpu number 0 initialization done CUMULATIVE DATA: throughput metrics: IOs/sec: 62.33 MBs/sec: 3.89 latency metrics: Min_Latency(ms): 3 Avg_Latency(ms): 15 Max_Latency(ms): 1600 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 39 7 1 15 1 8 14 3 4 3 0 0 0 0 0 0 0 0 0 0 0 6
As you can see, in the simulation of multiple 64-KB file I/O, reading speed is 14.96 MBs/sec, and writing speed is 3.89 MBs/sec. Like most USB flash drive, reading is much faster than writing on SanDisk Cruzer Blade 32GB Flash Drive.
