I-O Data today unveiled the SSPH-UT line of portable SSDs that are certified for use with PlayStation 4 and PlayStation 4 Pro as additional storage (USB mass-storage class devices). The drives feature USB 3.1 gen 1 (5 Gbps) host interface, and use a single cable for both power and host connectivity.

Available in capacities of 250 GB, 500 GB, and 1 TB, the drives offer sequential transfer rates of up to 300 MB/s, which should be viable for console gaming speedups, including in cases where you transfer game installations from the internal hard drive onto these. The compact portable drives come in two color options, maroon and gray. Both measure 8 cm x 8 cm x 1.5 cm (WxDxH), weighing 55 g. The drives are certified for 1.2 m drops. The company didn't reveal pricing.
