When benchmarking the TCS BGADrive SSD, we need to understand that different SSDs are created for vastly different tasks. We report on consumer SSDs and marvel at typical performance points in excess of 500MB/s, yet one wouldn’t consider sliding one of these into the US Navy’s newest F-35 Lightning and F-22 Raptor fifth generation fighters. They simply haven’t got the same feature set and build to withstand up to 80,000 feet of altitude, 40G shock, 16G vibration or temperatures of -40DegC-+85DegC. The TeleCommunication Systems Inc BGADrive (TBG31S) is a SATA 2 SSD and TCS build it as SATA 2 speeds are what’s required for such a device.
ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.
Initial ATTO benchmark results are very encouraging as they surpass listed specifications of 100MB/s read and 90MB/s write transfer speed performance.
Crystal Disk Benchmark is used to measure read and write performance through sampling of raw (0/1 Fill/compressible) or random data which is, for the most part, incompressible. In the TCS BGADrive 64GB SSD, performance results are very similar whether we test with compressible or incompressible data and, for this reason, results are displayed utilizing incompressible data.
A quick look at Crystal DiskMark result displays far lower 512 and 4K performance than we are used to seeing in todays typical form factor SSDs. Unfortunately we know of no other similar product for comparison to the BGADrive.
You may not see this for long (and its definitely not common) but you get a freebee simply for reading! Over the last little while, we have been assisting with beta testing new benchmark software called Anvil Storage Utilities which is an absolutely amazing SSD benchmarking utility. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and utilize in our benchmark testing.
Through Anvil Storage Utilities, we get a closer look at performance using 100% incompressible data as well as product IOPS throughput. Many
