CentOS 6.5 vs. CentOS 7.0 NAS Performance Comparison

After years of development, RedHat finally released the next major version of RedHat Enterprise Linux (RHEL) v7. RedHat Enterprise Linux is an enterprise-grade Linux distribution, which is frequently used in corporate data centers as an operating system for NAS storage devices. From the performance point of view, the new Linux kernel and the new default file system may have a significant impact on a NAS storage device and therefore it is very important to understand how the newly released RedHat Enterprise Linux version 7.0 compares to the last stable version 6.5.

The Linux app store is your safest friend

One of the cool features that Android and IOS have developed are application stores. Application trust is vital. When you download a program from those apps stores, you are getting something trusted, stable and frequently upgraded.

Something also integrated this same concept. Linux is another system that delivers a system that allows you to download and install programs that are designed to work with that system. There is no guessing if the program is safe to install. If it is not available in Linux's app store, don't pay it too much attention it. Install only if vitally needed.

Ubuntu created a very user friendly app store for downloads, "Ubuntu Software Center". Before you Google, check the products in your local store first.
