Testing Methodology
Over-Provisioning & Usable Capacity
Ordinarily, the limited 2.4% over-provisioning may impact long-term performance and lifespan. However, it appears that Western Digital has opted to mitigate that using a large 1 GB DDR3L SDRAM cache.
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 SSD to the 240GB HyperX Savage. As you can see, it delivered a sustained throughput of between 230 MB/s and 249 MB/s, with occasional bursts to 280 MB/s.
