Overclocking the Seagate 4TB NAS Hard Drive to its limits does not necessarily mean you will over-clock it beyond its limits and then face a host of problems. If you want to overclock the 4TB NAS Hard Drive however, there are some simple steps you can take to help you do so. I have noted below some of the more important things to keep an eye on and watch out for as you work towards the ultimate NAS Overclocking achievement. Keep reading...
NAS drives by default operate at their maximum data rate in the initial benchmarks they encounter. This is because the drives are designed to work at those high speeds right from the start. The reason why NAS operate at such high speeds is because of the very low power that they require. This reduces the running time of the appliance by as much as 40%. As a result of this benefit the manufacturers of NAS hard drives provide NAS with great names like Western Digital, SanDisk and IBM have all designed their appliances to have near-silent operation under load.
When testing a NAS drive under real world conditions there can be huge differences in the performance it shows. Under load the 4tb NAS drives we have tested have shown sequential read speeds that range from blazing speed to near silent speeds. When benchmarking the differences in speed are quite huge. The difference between one drive and another can be as large as 100MBps. Imagine the power of a USB port powered by a powerful laptop running at full speed when you plug it into a hub. Such speeds would blow the doors off your office!
Now let us look at the 4tb hard drive's Atto index. The Atto index is one of the most heavily used statistics in the evaluation of a NAS device. The Atto index is used for determining the amount of time it takes to perform a set of disk commands, and how long it takes to access the files on the NAS device. Because the number of disk transactions per second is directly proportional to the Atto rating, the higher the Atto rating the faster your NAS device will run. The throughput performance of the NAS device will improve dramatically with an increase in the Atto rating.
The performance of the disk heads inside the NAS devices are also crucial in determining the performance of the NAS device. High performing hard drives tend to be less likely to suffer from non-recoverable read errors per bits written. This directly reflects the performance of the computer's operating system since most NAS utilize Windows operating systems. Non-operating systems, such as Linux, do not suffer from these types of errors. Because of this any NAS product should be able to withstand and cope with the performance levels of the operating system that is being used.
To determine the best hard disk drive for your NAS device, you need to consider the two major factors that affect the performance of hard disks - the bandwidth and the total disk space. The greater the bandwidth and the larger the disk space, the faster the NAS device will run. While both of these factors can be controlled through the various configuration options available in NAS units, the total disk space cannot be changed unless you add an additional hard drive or additional NAS components to the network. Thus, if you only plan to use NAS software with limited capabilities you will probably be better off with a lower bandwidth and larger disk space drive in order to avoid the performance penalty associated with a larger hard drive.
The other factor that affects the performance of NAS units is the type of firmware that is present within the device. There are several different types of firmware that are available ranging from manufacturers such as Samsung, Western Digital, disks from sata, IBM and others. Each manufacturer uses a different patch used to implement the different operating speeds and characteristics of their NAS devices. As a result, it is important to perform your own benchmarks to determine which manufacturers have the fastest and most consistent NAS drives.
Another way to quickly test NAS drives is to look at the marks. PCMark 10th anniversary is one of the most commonly used benchmarking programs for enterprise-class computers. These types of tests allow a PC to demonstrate the capabilities of a NAS unit while providing performance information on the different storage arrays that they utilize. Although the test does not directly demonstrate the throughput, it provides a good measure of storage capacity capability and speed.
