W9TCY Dell 10TB 7200RPM SAS 12Gbps 3.5-inch Internal Hard Drive

W9TCY Overview Dell 10TB 7200RPM SAS 12Gbps 3.5-inch Internal Hard Drive. The Dell 10TB Hard Drive is a high-capacity, enterprise-level hard drive manufactured by Dell. The Dell 10TB Hard Drive uses Advanced Format (AF) technology, which increases the physical sector size on the disk from 512 bytes to 4,096 bytes (4K sectors). However, the Dell 10TB Hard Drive uses 512E (512 bytes emulation) sector size, which means it uses 4k physical sector size but the drive controller emulates the 512 bytes/sector.
