The drive is compatible ps4 is why I bought it. It is a hard drive 2 "1/2, standard size (ep .: 9.5mm), which embeds two trays 500mio each rotating at 5400rpm (rotationnage per minute) and a generous cache 64Mio. So far, nothing special though you tell me, except that it has integrated Seagate mini chip 8Gio SSD MLC NAND memory. Here is what they called the "Solid State Hybrid Drive", very rightly, as it merges the SSD and HDD technologies in the footprint of a single HDD 2 "1/2. This is not their first attempt in the matter, in fact, they are the 3rd generation SSHD, and this latest version seems to finally be good, offering both the speed of an SSD, the storage volume of a HDD, and especially 100 model 1Tio, advantageously a competitive rate.
