In our new point on the price of SSDs, we changed our entire product range. We decided to restrict the products to a single capacity: 120 GB (or 128 GB depending on the brand). The reason is simple: it is sufficient capacity for many people and the average price is correct. This type of DSS is perfect for a mid-range machine.
Models of 256 GB and more are still too expensive for most buyers and SSD of 64 GB and less limited interest in technology allowing only install the OS and some programs. Moreover, they distort the comparison, with a higher price per GB because of the unavoidable costs (controller, etc..).
Our comparison is therefore limited to six models: the C300 and C400 Crucial, Vertex Vertex 2 and 3 of OCZ and Intel 320 and 510. These six models are well distributed, representative of their generations. Other manufacturers offer "clones" of these SSDs, as Corsair, G. Skill, etc.. but the prices are close enough that if it poses no problem.
Models based Indilinx are definitely outdated, even if a new firmware could make them a youth. Other manufacturers, like Samsung or Kingston offers balanced products that can be interesting if found at a good price. They have the defect does not support standard SATA 6 Gbit / s performance but remain high, as all the current SSD.
Our six SSDs offer a 120 GB partition and use either memory in 34 nm - some vertex 2, the Intel 510 and the C300 - either from memory in 25 nm - Vertex 3, Intel 320, C400 and some Vertex 2 -. The preferred interface builders is obviously the SATA 6 Gbit / s, which can exceed the limit of 300 Mb / s.
Note, to take full advantage of this interface, a motherboard that supports the standard "natively" - directly into chipset - is necessary, the external auditors are often limited by the PCI-Express at least 500 MB / s. The price decreases much more slowly than last year, the flash memory - at least in SSD - remaining around 2 € per GB for a model 120 or 128 GB, it takes between 180 and 260 €, depending on expected performance.
In fact, a model - or rather a class of models - is advisable. Indeed, models based controller SandForce first generation, such as Vertex 2, offer performance very accurate and are offered at a lower price than the newer models. For most users, the lack of SATA 6 Gbit / s is not a problem for the (few) people who have compatible computers, the gains remain anecdotal in practice.
Attention finally to the point: OCZ offers a wide range of SSD controllers using type SandForce 2x00 with 3 Vertex, Vertex MaxIOPS 3, 3 and Agility Solid 3. The prices are very close, but performance may vary. Our advice is simple: the Vertex 3 is the most interesting choice. MaxIOPS version is more expensive but the difference is visible and models 3 and Agility Solid 3 were less efficient than the vertex 3 for the price difference is too small to be interesting.
