Kingston SSD vs WDC VelociRaptor

For a comprehensive look at the performance quirks of SSD's and their architecture, read Anandtech's excellent SSD Relapse. As you can see in the previous screenshots, HDTune records IOPS whilst performing its access time assessment. Again, these scores have been averaged over the 5 results displayed by HDTune. The average two year old could see the story here. The SSDNow V+ continues the general trend established by its relatives in the SSD family; stunning performance when it comes to IOPS and small file or block sizes. The following are sequential transfer rate tests, which generally bring up the best numbers for any drive. The SSDNow V+ starts off on a positive note, with a healthy 41% advantage in the average read transfer rate, although it's a somewhat hollow victory as its minimum transfer rate of 40.4 MB/s is whooped by the VelociRaptors 72.9MB/s minimum. This translates to an 80% margin in Western Digital's favour. The write tests are an altogether different story. Here, the VelociRaptor strikes back; approximately doubling the performance of the SSDNow V+ in the minimum and average transfer rates, although Kingston scores an 11% win in the maximum transfer rate recorded.   From HDTune's manual: "The file benchmark measures the performance for reading and writing files to the selected hard disk partition with different block sizes ranging from 0.5 KB to 8192 KB (x-axis)." Up to 32KB block sizes, the results are remarkably even. From there onwards, the SSDNow V+ takes over, peaking at just over 180MB/s for read operations, and around 140MB/s for write operations, although as you can see the results are fluctuating a bit. The VelociRaptor, whilst being outperformed, is at least more consistent, peaking at around 120MB/s for both read and write operations. << Back Next Page: >> Select Page Page 1 - Page 2 - Page 3 -
