PNY Attaché Flash Drive - 64-KB Benchmark
What is the 64-KB I/O benchmark performance of PNY Attaché Flash Drive (256 MB capacity)?
✍: FYIcenter.com
The I/O performance of reading and writing 64-KB files
of a PNY Attaché Flash Drive (256 MB capacity) can be
measured by running SQLIO with multiple 64-KB blocks with a large
stripe factor.
Here is the read performance test of PNY Attaché Flash Drive (256 MB capacity) with 64-KB blocks.
C:\fyicenter\SQLIO>sqlio -LS -kR -b64 -i64 -f64 -t1 -s30 -p0 using system counter for latency timings, 2343896 counts per second 1 thread reading for 300 secs from file D:\test.dat using 64KB IOs over 2048KB stripes with 64 IOs per run affinity on cpu number 0 initialization done CUMULATIVE DATA: throughput metrics: IOs/sec: 74.11 MBs/sec: 4.63 latency metrics: Min_Latency(ms): 13 Avg_Latency(ms): 13 Max_Latency(ms): 37 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 0 0 99 1 0 0 0 0 0 0 0 0 0 0 07:54 AM
Here is the write performance test of PNY Attaché Flash Drive (256 MB capacity) on 64-KB blocks.
C:\fyicenter\SQLIO>sqlio -LS -kW -b64 -i64 -f64 -t1 -s30 using system counter for latency timings, 2343896 counts per second 1 thread writing for 300 secs to file D:\test.dat using 64KB IOs over 2048KB stripes with 64 IOs per run affinity on cpu number 0 initialization done CUMULATIVE DATA: throughput metrics: IOs/sec: 19.83 MBs/sec: 1.23 latency metrics: Min_Latency(ms): 23 Avg_Latency(ms): 49 Max_Latency(ms): 95 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 0 0 0 0 0 0 0 0 0 0 0 0 0 100
As you can see, in the simulation of multiple 64-KB file I/O, reading speed is 4.63 MBs/sec, and writing speed is 1.23 MBs/sec. So for a PNY Attaché Flash Drive, reading is about 4 times faster than writing.
