The drives have better reliability compared to hard drives, but they have an advantage of higher capacity to the price you get them for. A sudden power failure can turn fortunes on SSD which is wrong to note that there will be aborted writes or even an absolute loss. This all depends on the models that you will be using. When you are using hard drives there can be a comparison of the cost and performance it will provide you. However, the same cannot be guaranteed for an SSD. The advantage of speed can be achieved only with some trade-offs. Some SSD drives are expensive but the response time is way higher than any driver. Now check out solid state drive repair .
Reasons for trouble
In case of hard drives, you can find that a rewritten file probably may occupy the same location on the disk surface as where the original file would have been present. However, in the SSD drives, it would be in a different place; in this case, cells for wear leveling. The wear leveling algorithms are complicated and intricate and to test them it would be an excruciatingly long process. Hence data loss that may occur in SSD may have been caused due to firmware bugs.
We all know that SSD drives were manufactured for the computers and augment the hard drives and they were eventually mounted on hard drives. Throughout the years they have decreased in size and become more compact in nature and have their significant form factors, and now it is designed to be installed on the computer. Whereas memory cards were for digital cameras and then they were used in cell phones, gaming devices, and other GPS units. These cards were smaller in size. They could be inserted and taken out any time and put back in any time. They were able to establish an interface with the computer and act like an SSD drive, though slower in comparison. There is so much reading and writing on the done on the especially done on the computer, the memory card is going to wear out quickly.
Failing of the SSD
There are many reasons for the failure of SSD drives
- Sudden power interruption
- If a chip fail
However, it has been tested that most of the SSD drives in the market are lasting way beyond their endurance specifications. The failure rates were lower; the only problem that was associated with the SSD drives was of the localized data which may have been caused due to unreadable blocks. There are times when these drives throw up unexpected conclusions. There can also raw bit error rates which go onto becoming exponential over some time. There has been correctable bit error rate even this will not test the failure rate of the SSD drives, though it may impact the user on a bigger scale.
Their times, when there would be bad blocks and the resultant, may be many blocks lost in the process due to chip failure. Though you will not see an increase in the number of errors as the time on the SSD drive use is going on. A bad block can be correlated to the creation of more bad blocks in the future; this can lead to eventual failure.
