CRYSTAL DISK INFO VER 3.9.3
Crystal Disk Info provides some excellent information about the SSD itself to include its health, operating temperature, product information, power on’ information as well as the characteristics of the SSD. In the case of the Apple SSD TS128e,we can confirm such things as the drives Power On Count and Power On Hours along with supported features, one of which identifies TRIM as being functional, at least when being tested in Windows 7.
To clarify for those not having read our first report, we found very few software programs to properly assess storage performance in the Mac environment and, in fact, we were tied to testing the Samsung SSD in a dual boot mode (Mac/PC) as the OS, and hardware such as the SSD, is proprietary to the system and a SSD cannot be simply removed, formatted, reset and benchmarked. This was the same with our new MBA.
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.
The ‘LSI SandForce Driven’ Toshiba is showing it’s colors right off and bringing in excellent performance of 551MB/s read and 523MB/s write while the Samsung sits just behind with 507MB/s read and a high of 460MB/s write. These results were expected as SandForce controlled SSDs excel in highly compressible data testing which is the bread and butter of typical consumer use.
