I am not an expert of this subject , but with respect to my readings in some e-mails in different mailing lists and from some relevant pages in Wikipedia about SSD drives , the following points are mentioned about SSD disadvantages ( even for "Enterprise" labeled drives ) :
SSD units are very vulnerable to power cuts during work up to complete failure which they can not be used any more to complete loss of data . MLC ( Multi-Level Cell ) SSD units have a short life time if they are continuously written ( they are more suitable to write once ( in a limited number of writes sense ) - read many ) . SLC ( Single-Level Cell ) SSD units have much more long life span , but they are expensive with respect to MLC SSD units . SSD units may fail due to write wearing in an unexpected time , making them very unreliable for mission critical works . Due to the above points ( they may be wrong perhaps ) personally I would select revolving plate SAS disks and up to now I did not buy any SSD for these reasons . The above points are a possible disadvantages set for consideration . Thank you very much .
