Galaxy unveiled its Captain line of mSATA and M.2 SSDs. Both the Captain-mSATA and the Captain-MAC (M.2) are based on a JMicron-made controller, with Intel-made MLC NAND flash. Both the Captain-mSATA and Captain-MAC come in capacities of up to 256 GB, offering sequential speeds of up to 520 MB/s reads, with up to 275 MB/s writes. Their 4K random read performance is rated at 72,000 IOPS, and 4K random writes at 70,000 IOPS. It's important to note here, that the Captain-MAC may feature an NGFF interface, but runs on a SATA 6 Gb/s link layer. It's one of the many examples of M.2 SSDs that have crept into the industry, with such an interface.
