Lenovo Thinkpad X1 Carbon Ultrabook Review and SSD Performance Analysis

SYSTEM STORAGE PERFORMANCE

Our analysis of the Lenovo X1Carbon ultrabook will occur through installation of our benchmark programs and testing within the X1. There is an unavoidable disadvantage in such testing simply because the SSD is not a new SSD and we are unaware how the SSD, OS or software on the system has been configured. Typically, pre-configured systems yield performance much lower than listed SSD specifications.

The software we will be using for todays analysis is typical of many of our reviews and consists of ATTO Disk Benchmark, Crystal DiskMark, AS SSD, Anvil Storage Utilities, and PCMark Vantage. We rely on these as they each have a way of supporting one another yet, at the same time, adding a new performance benchmark to the total picture. Much of the software is free and can be downloaded simply by clicking on the linked title.

CRYSTAL DISK INFO VER 5.0.5

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 SanDisk X100 256GB SSD,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.

Something that immediately comes to mind with the CDI result is the fact that this is a Lenovo ‘review sample’ ultrabook and one that has been through a few reviewers prior to our examination. This can be observed in the identification of 18 hours SSD use and the fact that the system has been powered on 109 times.

ATTO DISK BENCHMARK VER. 2.46

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.

ATTO performance of 422MB/s read and 396MB/s write is typical of a pre-installed and previously tested X1 Carbon, remembering that listed specifications for this drive are 500MB/s read and 430MB/s write.
