Chip manufacturer VIA Labs has released a new controller chip for usb 3.0 drives that nand memory chips and can control. The chip is faster than its predecessor, and also adds error correction to his features.
The new VL751 follows the VL750. Both usb 3.0 controllers have four channels for nand chips, but the new controller is faster. According to VIA Labs would be the chip write speeds up to 80MB/s, while read up to 120MB/s takes place. Thanks to read – and schrijfbuffers, and a pipelined ecc technology the performance versus the previous generation has improved.
The VL751 sends a maximum of thirty-two flashchips, and supports the latest nand chips of 2x – and 3x-nanometer. The controller is suitable for usb 3.0 interfaces, but can also fall back on the slower usb 2.0 and 1.1 connections. In usb 2.0 mode, should transfer speeds up to 35MB/s can be realized. The new Bulk-Only Transport protocol is supported, so no drivers for flash drives with the chip on board is needed. Currently, only samples of the VL751 available; when the chips are in products are not to be expected is not known.
