Las velocidades de los discos duros SSD encontrarán un cuello de botella en la conexión SATA III (600 MB/s) así que están pensando en usar PCI-Express para conectarlos: A Native PCI-Express Controller
Today, even PCI-Express SSDs use SATA format, as they have a SATA controllers, and also chips designed to ensure the transfer from PCI-Express to SATA, both impacting performance a,d limiting them to the same level than SATA III.
Marvel and OCZ announced to have developed the first native PCI-Express controller for SSD. With the reference number 88NV9145, it offers a direct connection to PCI-Express 2.0 for 128 GB of Flash memory on 4 channels. The max data speed of such module is 4x125= 500 MB/s, with 93,000 IOPS in reading and 70,000 IOPS in writing mode, respectively for 4 kB blocks, so excellent figures. If you need higher capacity or data speed, you simply need to pile up 88NV9145 chips and Flash modules. So, a PCI-Express SSD composed of 4x 512 GB will have a theoretical data speed of 2 GB/s on a PCI-Express 4x line, and its IOPS figures would be also increased. OCZ announced its goal to offer storage units based on 96 of such modules. It would then be possible to reach 12 TB of storage space, with max speed of 48 GB/s and IOPS higher than 8 millions in reading and 6.5 in writing mode....
Creo que ya nos dariamos con un canto en los dientes si los mac's montaran SATA III en lugar de SATA II (300MB/s) que es lo que montan ahora
