Benchmarks: AS SSD Benchmark

When running the As SSD Benchmark's sequential read test we find that the WD Black 4TB and Red 3TB drives offer the same operation, each sustaining 146MB/s. This made the WD Black 4TB roughly 25% slower than the Velociraptor 1TB while it was xi% faster than the WD RE 1TB.

This time when measuring sequential write operation the WD Black 4TB was a fraction faster than the WD Scarlet 3TB as it sustained 146MB/s once once more and once again it was roughly 25% slower than the Velociraptor.

The 4K-64 Thread test is not a benchmark that plays nice with mechanical drives and as a outcome the WD Blackness 4TB was significantly slower than the Samsung SSD 840 Pro 512GB. When compared to other difficult drives the WD Black 4TB performed quite well and was very consistent.

Access times are some other huge strength of SSD applied science and over the past few years we have become accustom to seeing times well below 1ms. However with mechanical drives the best you tin can hope for by and large is a few milliseconds. The WD Black 4TB had a read access time of 16.792ms, which is pretty average really, making it much slower than the RE 1TB and Velociraptor 1TB in this exam.

Whereas the read access time of the WD Black 4TB was quite boilerplate, the write functioning is remarkable. The WD Blackness 4TB took just 2.170ms to access when measuring write performance, making it faster than the RE 1TB and Velociraptor 1TB.
