The emergence of solid-state drives (SSD) in the storage subsystem space was truly a revolution in the way of storing data in all aspects. In the past, storing data on traditional hard drives (HDD) was not done without hassles, and one would encounter a few problems started from slowness to low reliability. That’s because a hard drive employs mechanical parts that work together to function properly, and everything related to mechanism is not free of problems related to it. That’s why, with a nonvolatile memory chips placed together in blocks, a solid-state drive can handle large amount of data silently with confidence due to the extreme reliability they characterized.
Finding the fastest hard drive among the so many brands over there to inject a new life to your old computer or to use it as the primary storage device for a new build is not as simple as it seems, because there are many manufacturers claim that their drives are the fastest on the market, while in fact there are still faster than them which you might be unaware of. For that reason one cannot dispense with reading the reviews and users’ experiences with every drive so as to reach the right conclusion regarding each of those drives, and this does not seem logical after all for most computer users.
One of the few computer components that provoke hesitance on whether to buy them or not is a solid state drive (SSD). That’s because an SSD is not cheap compared with the regular hard drive, and moreover they come in much smaller space than traditional hard drives. While traditional hard drives have hit the level of 10TB of disk space, SSDs are still striving to exceed the 1TB cap. This manifests to you how buying a 1TB SSD that costs $500 is a big hesitance to most people, whereas you can buy with that price 2 5TB hard drives with decent speed. But why after all consumers still go for SSDs? What’s the charm in them? Is it just speed or is there anything else?
A new solid-state drive (SSD) is supposed to run at its maximum speed when you first buy it, then gradually it begins to degrade over time when you use it and save lots of data to it. The reason for that basically relies on the way flash memory chips behave and handle data, which is different to that of a traditional hard drive. For this reason the SSD manufacturers invented some utility tools to overcome this problem and maintain the health and performance of a solid-state drive without undergo any kind of slowness or delinquency in performance. But how is that done? And is there any other method to reset the SSD performance to its factory settings?
Many hard drives suffer from bad sectors that have been discovered through checkdesk command on windows or any other utility provided by the operating system that hard drive runs. Those bad sectors don’t usually store data but they do impact the performance of the hard drive, and often cause errors in loading applications or even loading the operating system itself. The blue screen for example is caused in many cases by those bad sectors. On the other hand, fixing those bad spots on your drive is not difficult, and there are so many software utilities offer this functionality for free, and some are OS built-in, such as “check desk” in all versions of Microsoft Windows.
When your hard drive become unbearably slow, experts advise to fragment it to get it much faster than its current state. Truly when this is done, you will observe a dramatic change to the speed of your drive, and programs will launch faster, windows boots up in lesser time, and your games will load quicker than before the process of defragmentation. But why is defragmentation is important like that? and why does it speed up your hard drive and make it smoother in operation? Here you will probably get the answer that will help you understand the whole matter of this critical process in hard drive maintenance.
You may have already heard that a traditional hard drive is made with something called “platter” that spin so fast with an arm that ends with a tiny needle that helps extract the requested data stored on those platters. You may wonder then what those platters are and how they work. In fact, this knowledge has been confined into a narrow circle of people whose study or work is related to hard drive in specific or technology in general. But this has changed over the last few years where knowledge became accessible to almost everyone and now finding how a hard drive works and what it is made of is no longer a difficult thing to carry out.
According to the original owner of magnachef.org, he stated in his blog the following: I recently read “Zenoss Core Network and System Monitoring” by Michael Badger and from Packt Publishing. I was excited to hear that there was a book available that covered the Zenoss monitoring system in a more structured and step by step method (as compared with documentation found online). When I began with Zenoss, the documentation was very high level and left much to be desired. This generally caused me to spend a lot of time on IRC, in the forums, and trying to figure out what to do with the simplistic documentation that existed. This book is exactly what I was looking for when I started to venture into the world of Zenoss, and was a nice review for someone (like me) who is comfortable with the system. The book does a real nice job of giving an overview of the system architecture, then steps through each stage of an example installation and configuration, device and event management, generating reports, user management, transforms, etc.
I would also recommend this book for anyone who is new to network and system monitoring, as the book goes into the details of installing and configuring SNMP, WMI, Windows Event Logs, and Syslog.
This book is a must have for anyone who plans on using Zenoss or anyone that is wondering if Zenoss is the right monitoring solution for them.
