Crucial C300 64Gb RealSSD Review

Most recently, The SSD Review has completed its build of a new Test Bench which we hope to be future proof, in that, it is capable of testing new SATA3/USB3 hardware releases. Can you imagine our surprise when we started to get requests from hardware manufacturers asking if we would like to run their their SATA3/USB3 hardware through its paces?

One such manufacturer was Crucial who was quick to send us a Crucial C300 64Gb SSD a few weeks back and welcomed our testing and thoughts on their SATA 6Gb/s drive which had just been released. I have to admit that I couldn’t contain myself and threw it in within minutes of receiving only to have it return an initial sequential read speed of 357 MB/s!!!
To back up just a bit, SATA (Serial Advanced Technology Attachment) is the interface that is contained within ssds, hard drives, optical drives and other devices which connects to your computer motherboard by way of a cable. It is important to have a knowledge of this because SATA has been released in 3 revisions, Rev. 1.0 which is capable of speeds up to 1.5 Gb/s, Rev. 2.0 which is capable of speeds up to 3Gb/s, and then the newly released Rev. 3.0 which is capable of speeds up to 6Gb/s. How does this translate into hard drive or ssd speeds? A SATA 2 SSD can technically only reach as high as 300MB/s for its sequential read speed although I don’t think we have seen one above 280MB/s. All this changes with SATA 3 and we will now see speeds above that reached as with our new C300. A point of interest to many interested in reaching these new heightened levels of bandwidth is that you cannot simply buy a new SATA 3 drive and throw it into your SATA 2 capable system and expect to reach similar speeds. A hardware upgrade is also necessary in the system but don’t fret because we are now seeing SATA 3 adapters on the market for very reasonable prices.
CONSTRUCTION
The C300 is constructed of a grey metal exterior casing on the front and back, separated by a plastic frame and held together by four small screws. Of course, there is also a sealing sticker on the side that would void your warranty if it were damaged indicating that you had opened the unit.

Inside we have a single PCB (Printed Circuit Board) which has the SATA 3 interface seen on the right side of the PCB, the Marvell controller which is distinctly stamped with the company logo as well as 8x4Gb 34nm NAND flash memory chips on each side which makeup for the 64Gb size of the drive (16Gbx4). NAND flash is a type of non-volatile memory which does not require continuous power in order to retain its data. This drive is practically identical to its big brother of the 256Gb size and the only difference is the size of each NAND flash, the 64Gb containing 16x4Gb each and the 256Gb C300 containing 16x16Gb NAND.
.
This directly relates to the maximum write speeds of either drive because, as we know, the 256Gb version is advertised at a maximum sequential write speed of 215MB/s whereas the 64Gb version is 75MB/s. The reasoning behind this is the fact that the 16Gb NAND (256Gb ver) each contain 4 NAND dies whereas each 4Gb NAND (64Gb ver) contains 1 NAND die. In the end, we learn that it is not any form of a cap put on the drive through its firmware. There is also another chip on the reverse which is the 256MB DDR3 buffer to assist in the drives quick speed and smooth operation.
