The SSD Review The Worlds Dedicated SSD Education and Review Resource |

It wasn’t two years ago that people were happy with these marks for a RAID system and look where we are at today. I can honestly say that after building my first system from scratch, this was a sight to behold. At first glance, its a bit of a double sided view because we see the absolutely amazing sequential read score of 357MB/s and then, on the other hand, we are left wondering how the low write scores of 76MB/s will translate into real world tests. We think you will be a bit shocked at how the Crucial C300 fared but for now lets remember the importance of that 53MB/s for the random 4kb write scores. Remember that the 4kb random writes are the single most important disk access method that will result in visible system improvement.
All scores below are reflected in MB/s.

Now if you are reading this review and wondering just how much difference there is between a SSD and a hard drive, things might just be starting to fall into place. If we compare the 4k random write disk access speeds to that of the Samsung HDD (53 vs 0.88) and are remembering that the most visible improvement that you will see in your system comes from this, you will take note that the SSD is moving information 60 times faster than the hard drive. For those auto enthusiasts, that roughly a Volkswagon travelling at 10mph and being passed by someone going 600mph in a rocket trying for the land speed record.

ATTO and HDTune Pro also show us that, regardless of whether it is in SATA 2 or SATA 3, the Crucial C300 rates higher in sequential read speeds than all of the other test drives. This chart does start to show us another little tidbit with respect to disk access time between SSDs and hard drives which is that SSDs have a much better disk access speed than hard drives. In this case, the Crucial C300 fares 192 times faster at disk access than the Samsung HDD (.1ms vs 19.2ms). Disk Access is the time it takes to find a piece of information stored on a storage medium. Things work a bit different with a SSD, as you can imagine, because there are no moving parts and information is then found and then retrieved in a steady flow. A hard disk, on the other hand, stores information on a magnetic platter which spins at very high speeds. An arm must pass over and find the exact spot through each pass. To add to this, the information is picked up in blocks at a time which, depending on the size of the file being retrieved, can stress the hard drive and reduce the speed itself.
