SandForce in the MSAT: 16 to 120 GB

At Computex, the SSD-based SandForce in MSAT had been presented. RunCore, atypical solutions specialist, proposes a complete range of SSD in this format, with a capacity ranging from 16 to 120 GB The MSAT, remember, is a physical format that transmits a signal to a SATA connector identical to that used in the cards Mini Card.

SSD in MSAT thus resembles a Wi-Fi card for laptop - for example - but instead of transmitting the PCI-Express and USB 2.0, SATA is working. Standardized, the MSAT is particularly used in the Chromebook Samsung and some Intel to integrate SSD as "cache." RunCore proposes a complete range.

The first models are the T50, models SF-2281 and SATA 6 Gbit / s. The advertised speeds are unrealistic as ever, with 550 MB / s read and 470 MB / s write. Given the capacities (30, 60 and 120 GB) and the size of the SSD, the incompressible flow of data will be much lower. Do not hope to exceed 75 MB / s write on models 30 and 60 GB, for example.

The I50 is limited to a SATA 3 Gbit / s and 280 Mb / s read (270 MB / s write). Same problem as the T50, the physical format limits the number of channels and therefore the actual performance. Finally, versions of "Lite" for netbooks and other Chromebook using a SF-2141 controller, a less rapid than the SF-2181 and limited to only 4 channels.
