Read Bandwidth / Write Performance
Read Bandwidth For this benchmark, HDTach was used. It shows the potential read speed which you are likely to experience with these hard drives. The long test was run to give a slightly more accurate picture. We don’t put much stock in Burst speed readings and thus we no longer included it. The most important number is the Average Speed number. This number will tell you what to expect from a given drive in normal, day to day operations. The higher the average the faster your entire system will seem.
As expected the sequential read performance is basically double of that of a single 3TB Barracuda. This has always been a major strong point for RAID 0 and comes as no surprise. With that being said, these numbers are impressive and can easily compete against even 240 - 256GB Solid State Drives.
Write Performance For this benchmark HD Tune Pro was used. To run the write benchmark on a drive, you must first remove all partitions from that drive and then and only then will it allow you to run this test. Unlike some other benchmarking utilities the HD Tune Pro writes across the full area of the drive, thus it easily shows any weakness a drive may have.
As with the sequential read, the write performance is close to double of what a single 3TB Barracuda can accomplish. This minor variation is in all likelihood due to margin of error and the fact that the second drive was not quiet as fast – on average – as the first Barracuda drive was. The minor variation is neither here nor there and as with sequential read performance does not tell us anything that we were not expecting: namely that sequential performance is always the strong suit of RAID – 0 and these numbers are impressive to say the least.
