Crucial RealSSD C300 SATA 6Gbps SSD

Final Thoughts and Conclusions

The Crucial RealSSD C300 256GB SSD is an amazing SSD that has the ability to take advantage of the SATA 6 Gbps interface. When we first looked at SATA 6 Gbps performance using the Seagate XT 2TB hard drive we found the burst speed to be impressive, but found that a hard drive was able to fully use the new interface since it wasn't fast enough. We were seeing the Seagate XT 2TB hard drive have a maximum read transfer rate of 144MB/s, which is nothing to write home about these days. The Crucial RealSSD C300 on the other hand was able to peak at 387MB/s in ATTO, which is insane for a single SSD. When it comes to read performance nothing on the market today can beat the Crucial RealSSD C300 256GB SSD! This drive has spectacular read performance and the write performance is not too far behind other drives like the OCZ Vertex LE.

When it comes to pricing the 256GB model that we have here today carries an MSRP of $799 and is available for consumer purchase at Crucial.com today. With a total free capacity of 238GB that comes out to $3.36 per GB of storage space. This is expensive, but not out of line compared to other SSDs on the market today. The OCZ Vertex LE 100GB SSD retails for $399 and has a free capacity of 93.1GB, which means that you are paying $4.29 per GB of storage space. The Intel X25-M Gen 2 160GB SSD has 149GB of free space with a street price of $429.99 shipped. This places it at $2.89 per GB, so as you can see the Crucial RealSSD C300 is roughly 16% more expensive than the Intel Gen 2 34nm drives, but offers better performance in nearly every benchmark we ran the two drives on. 

If you are looking for an SSD that supports the TRIM command and want to move to the SATA 6Gb/s interface to get the most performance from your system the Crucial RealSSD C300 256GB drive is the way to go. You can't argue with sequential read and write speeds of up to 355 MB/s and 215 MB/s in a consumer based SSD. This is how SSDs should perform and we can't wait to see more SATA 6 Gb/s drives come on the market down the road.
