Sage Microelectronics to power 5TB SSDs

Sage Microelectronics has released the Sage S681, a 10-channel controller that will allow SATA SSDs up to 5TB of capacity. Current SATA SSDs max out at 2TB, and there aren't any future products announced that will break the 2TB barrier. Sage Microelectronics intends to bust past the 2TB barrier by utilizing eMMC, SD, or MMC. The S681 will utilize the low cost structure of these devices to keep cost down. Each channel will support up to 512GB of memory via a 10 X 4 X 128GB layout of typical flash memory cards.

The new controller supports a SATA II interface, which denotes lower performance than the typical SATA III connection favored by today's top-flight SSDs. This limits maximum read/write speed to a paltry 260/225 MB/s. The S681 features a RISC CPU core to manage the bus, plus extra cores that support two memory card channels. Five-channel and four-channel variants, the S682 and S685, are also available.
