HD Tach is a low level hardware benchmark for random access read/write storage devices such as hard drives, removable drives (ZIP/JAZZ), flash devices, and RAID arrays. HD Tach uses custom device drivers and other low level Windows interfaces to bypass as many layers of software as possible and get as close to the physical performance of the device possible.
Benchmark Results: The Kingston SSDNow V+ 256GB MLC Solid State Drive is a mainstream level SSD and the performance results clearly show that. This benchmark was done on the brand new drive, so performance degradation is not an issue here and this is as good as it gets. The drive averages 206MB/s read and 169.9MB/s write. The burst speed of the SSDNow V+ 256GB was a very nice 239.5MB/s.
Comparison Chart: When comparing the Kingston SSDNow V+ 256GB MLC SSD to other popular 2.5″ notebook hard drives you can see that it scored at or near the top. That is not bad considering it is being compared to ten other SSDs and five hard drives. It should also be pointed out that the Kingston SSDNow V+ series is a re-labeled Samsung PB22-J 256GB SSD, which is also what is being used inside the Corsair P256SSD and the OCZ Summit 120GB SSD that we have already tested. Expect the Corsair P256, OCZ Summit 120GB and the Kingston V+ Series 256GB to all score close to the same in all of the benchmarks. The results of HD Tach’s CPU utilization test don’t mean much as the application has a +/- 2% margin of error and the results of the benchmark range between 0-3%, which doesn’t represent a significant difference.
