VisionTek 120GB USB 3.0 Pocket SSD Drive Review
ATTO Disk Benchmark & Anvil Storage Utilities
ATTO v2.47
ATTO is one of the oldest drive benchmarks still being used today and is still very relevant in the SSD world. 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.
VisionTek 120GB USB Pocket SSD on USB 3.0:
Benchmark Results: ATTO showed VisionTek USB Pocket SSD 120GB drive maxing out at 452 MB/s read and 436MB/s write in the standard overlapped I/O benchmark when connected to the ASUS Z97-A motherboard with the SATA III interface. This drive is rated at having up to 455MB/s sequential read and 440MB/s sequential write speeds, so we are running just below the rated speeds. Keep in mind that we are testing on a platform that supports the UAS Protocol to ensure the best speeds possible.
Anvil Storage Utilities 1.1.0
Along with the move to a new platform, we decided to make a change in one of the benchmarks. There’s a relatively new benchmark called Anvil Storage Utilities that is in beta but close to production. It’s a very powerful tool that measures performance through a variety of tests which can be customized. Since some of the tests more or less duplicate what we get from other benchmarks we use already, we decided to use the IOPS (Input/Output Operations Per Second) testing on 4kb file sizes at a queue depth of 4, 16, and 32. IOPS performance is something SSD makers tout quite a bit but we generally don’t do a lot of IOPS testing because frankly a lot of users can’t relate to IOPS metrics as well and it tends to be more meaningful to the enterprise/server crowd. Still, it is another performance indicator with relevance and while some drives post good MB/s numbers, their IOPS scores aren’t always commensurate which this test will prove out.
VisionTek 120GB USB Pocket SSD on USB 3.0 – Application Test:
Benchmark Results: The overall Anvil SSD Benchmark score was 2,067.16 with 285MB/s read and 211MB/s write speeds on the Applications test setting of 46% compression. The 4K QD16 write IOPS were just around 37,000 and the read IOPS were roughly 21,000 IOPS.
