Not only are they increasingly the norm for mid-range laptops and pre-built gaming systems, but we've seen huge leaps in performance lately.

Shame, then, that its application performance isn't quite as world beating.

Reviews Word on the street for the Crucial RealSSD C300


9.1
It is also backwards compatible to SATA II and SATA I. Crucial is using 16 flash chips, the flash controller and a DRAM chip in their design.

9.5
First up, it's reasonably priced – a little bit more expensive than Kingston's perhaps, but a lot cheaper than OCZ's offerings.

Overall

9.0 Out of 10

What People Are Saying Give it to me straight

Performance

It boasts read speeds like nothing we've seen before, which finally make use of the raised bandwidth cap of SATA 6Gbps and beats all but the very best drives in write operations too.
by Tech Radar (Sep, 2010)
SSD read speeds have been getting very close to the limits of the older SATA 3Gbps bandwidth cap.
by Tech Radar (Sep, 2010)
At only $2.10 per GB it is considerably more affordable than the Sandforce drives out there - and delivers equal or higher performance.
by techPowerUp!

Speed

When running on a SATA-II controller it is able to surpass most of the Sandforce based drives, in 6 Gb/s mode it even manages to be the fastest SSD we tested so far.
by techPowerUp!
This simulates lots of small files handles simultaneously – which is exactly what happens in normal desktop apps that slow your PC down.
by Tech Radar (Sep, 2010)
In scenarios where the SSD will not gain from the faster speeds of the SATA 6 Gbps interface we also noticed slightly lower performance of the Marvell 6 Gbps controller chip on our ASUS U3S6 card when compared to the Intel ICH10, so that might be an additional point to consider.
by techPowerUp!

Interface

The SATA 6 Gb/s tests were conducted using an ASUS U3S6 PCI-Express based SATA 6 Gb/s controller.
by techPowerUp!
Compared to these drives, the C300 has a major unique selling point: SATA 6 Gb/s support (some people might call it SATA III, but the correct name is SATA 6 Gb/s).
by techPowerUp!
9.1Crucial's RealSSD C300 shows impressive real-life performance in both SATA-II and SATA 6 Gb/s mode.
by techPowerUp!

Price

But if you want the fastest read times bar none and a very attractive price point to boot, then the Crucial C300 realSSD is a clear winner.
by Tech Radar (Sep, 2010)

Capacity

The flash chips are made by Micron and have a capacity of 8 GB each.
