Technology related to data storage has been making rapid strides with new techniques and advances in existing technologies. Nowadays the hard disk drives are quite popular but they do have their own set of disadvantages such as the presence of moving metal platters and read-write heads, which makes the system prone to various kinds of mechanical failures and relatively lower read-write access times.

One of the recent additions to the data storage devices are the solid state drives or SSDs. An SSD simply refers to a data storage device which is comprised of solid state components. Of course it must be mentioned that the term “recent” does not imply that SSD came on the horizon just few weeks or few months ago. Infact the history of SSDs can be traced back to at least three decades when semiconductor based SSDs were deployed in supercomputers built by companies such as IBM and Amdahl.

In the modern context, an SSD would refer to a non-volatile flash memory fabricated out of semiconductors, chips and other types of non-mechanical parts. You might be tempted to equate this with the external USB flash drives which we often use, but SSDs on the other hand are normally used internally in lieu of the traditional hard disk drives.

SSDs have to offer several advantages over hard drives since they are totally made out of non-mechanical components, the risks associated with the latter are literally eliminated. This makes an SSD quite energy efficient vis-à-vis their hard drive counterparts. The access times to data is also reduced drastically because there are no spinning motors or platters involved but only electronic signals are involved, which makes the process much faster on the whole. It was demonstrated by Fujitsu recently that the boot up speed on a normal laptop notebook was increased by as much as 20% when SSD was used in place of the conventional hard disk inside the computer. To paraphrase the words of the man who first stepped on the moon – “these factors may not seem much productive from the individual standpoint, but the overall gain in efficiency from such small steps could be a giant leap for an enterprise.”

One of the most important factors associated with the use of solid state drives is the higher level of reliability they have to offer. Hard drives by nature of their construction are quite fragile and even minor impact could result in data loss. Of course there are provisions for data recovery such as hard drive recovery and RAID data recovery, apart from data back-up facilities; still the system is quite sensitive to such factors. The use of solid state devices minimizes such risks, even if it may not be able to fully nullify them.

Yet this does not mean to say that SSDs are a viable option in every situation. One of the most important grey areas where SSDs lack behind traditional methods of data storage is the cost factor. We know that financial constraints present one of the most formidable challenges to any organization. SSD storage is several times higher in cost of storing data in HDDs for the same amount of data. This means that for use in gigantic data volume handling, the cost of the overall data storage system would be several times higher. Of course it needs to be seen by concerned personnel that the optimum trade-off between performance and cost is achieved at which intermediate point.

W can see that the use of solid state data storage devices will certainly occupy prominent position in the days to come and would reduce problems associated with data recovery, data loss etc once the other factors such as cost are brought under control.

The first sign of impending failure may be slower work hard. This can be seen that the operations on file system – like e.g. copy of files, take more time. When the hard disk seems unusual noises, it also suggests that it is in grave danger. These “bad sounds” can be sounds of grinding, sweeping, creaking or knocking. The most serious signs are data writing and data reading errors that can be recognized as problems with accessing the data stored on disk – you are given false information of file sizes, you are unable to get information of files properties, changes in files (e.g. documents) are not saved, your operating system (e.g. Windows) is unable to lauch or you are welcomed with scanning the surface of the disk process every time you try to run your operating system.

If you notice at least one of these symptoms, we suggest you should immediately do copy of your most important files stored on your hard disk! But what to do when your hard drive fails when your backup is not done or data you need back is not backed up.

How it is sad by IT scientists the number of processed and stored data estimated for each citizen of the Earth is over 1 GB (one gigabyte), and that number is constantly growing. The biggest problem in that the perfect protection of medias against the loss of stored information was not invented yet, and what is most probably will never be. Even accredited as most reliable data storage matrix systems give a maximum of 99.9% security of data safeness. Still it is possible to save your nerves . You may simply do it by regular backup files from your disk partition where you keep your data. Good example of cheap and simple but still effective backup method is to record your files on CD or DVD medias.

According to Murphy’s law data loss of your files will happen when you store on your hard drive (or any other media ) with numerous of relevant files and other most wanted data. At that moment you may start to fear of losing your most valuable document. Maybe even worse – you just lost it! When such a situation happens, you may find that your last several months (or even a year or more) efforts and work done has been wrecked. It is good idea to use not only standard ways of backup. As a good example of not traditional backup methods are store files on e-mail accounts where e-mail messages are not removed in a some period of time, usage of free disk space at network servers. Business owners should also consider hire professional company that provides backup solutions and data archives services.

However, it is not matter what procedures for having data archived you have provided and performed, if you are not able to get data of the copy you had done. Thus protect your data by creating backups with regular schedule and after each backup is done, you must verify it. In other way one day you may find that your last backup does not contain proper files or simply is unreadable (not works). As SalvageData Recovery case managers say, a lot of people do backups without checking if in case of data loss they would be able to recover data from backup. In most cases copy of files contains errors, wrong or even not all files that should be there.

It is also important to remember not to copy backup files directly to disk from which they were lost. In case of any further problems you will be available to take a chance of recover data from damaged media and a copy, that provides bigger chances to recover your data by data recovery experts.

Another good practice is not to store most guarded files on system partition (the logical disk that you have your operating system installed, most likely C drive when you use Windows family operating systems). It will prevent you form losing data in case of logical errors and malfunctions caused by viruses and other unwelcome applications.
