These days, everyone is talking about SSDs (also known as solid state drives), but it's a very controversial topic. Claiming the future to be theirs, these replacements for the good old magnetic disks come along with advantages like noiseless operation or shock resistance on the one hand. But reports about a very short lifetime, going hand in hand with losing data, or about a fairly high power consumption - when compared to HDDs (hard drive disks) - because of a small number of operation modes, on the other hand, make you wonder a little. Hoping to help you understanding this technology a bit better, we present you a review of both a MLC and SLC solid state drive. These come from the manufacturer CSX (Compustocx) and are capable of storing 30GB. Let's have a look at the specifications before we dig deeper.
