Colorful today rolled out a trio of budget SSD lines. These include the CN600 series, the CN500 series, and the SL500 series. The CN600 series is built in the M.2-2280 form-factor with PCI-Express 3.0 x2 wiring, and is characterized by a heatspreader over the controller and NAND flash chips; the CN500 is also built in the M.2-2280 form-factor, but features SATA 6 Gbps wiring; whereas the SL500 is a conventional 7 mm-thick 2.5-inch drive with SATA 6 Gbps interface. All three drives are available in 240 GB capacities.
The CN600 series drives combine a Realtek RTS5760 controller with TLC NAND flash memory, and offers sequential transfer speeds of up to 800 MB/s, with up to 700 MB/s writes, and up to 50,000 IOPS random reads, with up to 100,000 IOPS random writes. The CN500 series drives, on the other hand, pair a Silicon Motion SM2246EN controller with MLC NAND flash, offering up to 530 MB/s reads, with up to 250 MB/s writes, and up to 70,000 IOPS random reads, with up to 60,000 IOPS random writes. Lastly, there’s the SL500 series, which combine Silicon Motion SM2256 controllers with TLC NAND flash, serving up 530 MB/s reads, with up to 450 MB/s writes, and up to 80,000 IOPS random access. The company didn’t reveal pricing or availability information.
