SanDisk 64GB Extreme USB 3.0 Flash Drive ReviewSun, Jul 29, 2012 - 10:00 AM
SanDisk Extreme USB 3.0 Performance
ATTO is one of the oldest drive benchmarks still being used today and is still very relevant.. ATTO measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and places the data into graphs that can be very easily interpreted. The test was run with the default runs of 0.5kb through 8192kb transfer sizes with the total length being 256mb.
Benchmark Results: The SanDisk 64GB Cruzer Extreme USB 3.0 flash drive does better than the rated 190MB/s read and 170MB/s specifications. We were able to hit 205MB/s read and 181MB/ write speeds on this drive in ATTO with the default benchmark settings!
CrystalDiskMark 3.0.1c x64:
CrystalDiskMark is a small benchmark utility for drives and enables rapid measurement of sequential and random read/write speeds. Note that CDM only supports Native Command Queuing (NCQ) with a queue depth of 32 (as noted) for the last listed benchmark score. This can skew some results in favor of controllers that also do not support NCQ.
Benchmark Results: Again, the speeds exceed specification on the sequential tests. We were hitting 215MB/s read and 189MB/s write on the sequential test. The 4K benchmarks were also impressive for a USB 3.0 Flash Drive with 17MB/s read and 10MB/s write!
HD Tune v5.00 File Benchmark:
HD Tune Pro 5.00 is a hard disk utility with many functions. It can be used to measure the drive’s performance, scan for errors, check the health status (S.M.A.R.T.), securely erase all data and much more. It’s a popular benchmark and perfect for testing thumb drives.
Benchmark Results: HD Tune showed that we averaged 186.4MB/s read speeds with a peak speed of 191.4MB/s. The burst rate was 66.1MB/s and the access time was 0.240ms.
Benchmark Results: The final benchmark we will be doing today is the HD Tune file benchmark. This benchmark showed 198MB/s read and 176MB/s write transfer speeds! The block size measurement benchmark showed good performance again with read speeds just under 200MB/s and write speeds that look to be around 160MB/s.
