Testing Methodology

We tested in both Windows 7 and Windows Vista, with the latest updates. We chose to use IO Meter 2008, AS SSD Benchmark, ATTO Disk Benchmark as well as our “old faithful”, WinBench 99 2.0, with the following tests :

  • Platter Data Transfer Profile
  • Business Disk WinMark 99
  • High-End Disk WinMark 99
  • Disk Transfer Rate (Beginning)
  • Disk Transfer Rate (End)

Business Disk WinMark 99 is a real-world simulation based on three office application suites – Microsoft Office 97, Lotus SmartSuite and Corel WordPerfect Suite 8, as well as a web browser, Netscape Navigator. They are quite dated, but should still reflect the usage patterns of users in an office environment using such applications. The test runs through a script that keeps multiple applications open, while it performs tasks that switches between those applications and Netscape Navigator. The result is the average transfer rate during the script run.

High-End Disk WinMark 99 is a real-world simulation based on AVS/Express 3.4, FrontPage 98, MicroStation SE, Photoshop 4.0, Premiere 4.2, Sound Forge 4.0 and Visual C++ 5.0. However, it differs by running the applications serially, instead of simultaneously. There are individual results for each application but in this comparison, we will be looking only at the weighted average score, which is the average transfer rate during the tests.

Unfortunately, WinBench 99 is not fully compatible with Microsoft Windows 7, registering a SetFilePointer error in the Disk Access Time test. So, we were not able to obtain any Disk Access Time results.

In addition, it would keep crashing if the hard drive was tested with a single partition. This is likely due to a limit on the size of the partition that is supported by WinBench 99. We came up with a workaround by dividing the hard disk drive into 5 partitions of equal sizes. We then tested each partition individually and averaged the results.

Over-Provisioning & Usable Capacity

This 1TB WD Blue 3D NAND SSD (Price Check) has a maximum storage capacity of 1,024 GB, courtesy of eight 128 GB SanDisk 3D NAND chips. Of that, a mere 24 GB has been set aside for garbage collection, wear levelling and replacement of failing blocks.

Ordinarily, the limited 2.4% over-provisioning may impact long-term performance and lifespan. However, Western Digital mitigated that using a large 13 GB pseudo-SLC write cache they call nCache 2.0.

After it is formatted in NTFS, the actual formatted capacity is 1,000,202,039,296 bytes. This is slightly (202 MB) more than the official formatted capacity of 1,000 GB.

With about 124 MB of space allocated to the NTFS file system, the actual usable capacity is just above 1,000 GB.

 

Transfer Rate Profile

We compared the 1TB WD Blue 3D NAND SSD (Price Check) to the 1TB WD Blue SSD. As you can see, it has a sustained throughput of about 378 MB/s, which makes it almost twice as fast as the 1TB WD Blue SSD, which uses TLC NAND memory.

High-End Disk WinBench 99

The 1TB WD Blue 3D NAND SSD (Price Check) did very well in the High-End test, beating virtually all other competitors, except for the 240 GB HyperX Savage and the 240 GB Intel 520 Series SSDs.

Transfer Rate Range

This chart shows you the range of memory cell-to-controller transfer rates for SSDs, or the range of platter-to-buffer transfer rates from the innermost track to the outermost track in HDDs.

Despite boasting an official peak read speed of 560 MB/s, the 1TB WD Blue 3D NAND SSD (Price Check) could only hit 386 MB/s. That is impressive in its own right, but puts it below the 256 GB OCZ Vector and the 240 GB HyperX Savage SSDs.
