HDD internal 2.5

The Seagate BarraCuda 4TB is a 2.5-inch internal hard drive for general-purpose computer storage and high-capacity mobile or compact systems. This exact model is ST4000LM024 and uses a SATA 6Gb/s interface.Seagate specifies a 5400 RPM spindle speed, 128MB cache and shingled magnetic recording (SMR) for this 4TB version. The maximum sustained data transfer rate is listed at up to 140MB/s; SATA 6Gb/s is the interface bandwidth and does not represent the sustained read or write speed of the disk. The 2.5-inch format makes the drive suitable for systems that accept its physical dimensions, but this capacity uses a 15mm drive height.That thickness is greater than the 7mm or 9.5mm bays found in many laptops, so physical clearance must be checked before installation. The drive uses 512-byte logical sectors with 4096-byte physical sectors and supports Seagate Multi-Tier Caching Technology. Capacity, cache, RPM, recording technology and physical height in this listing are tied specifically to ST4000LM024 rather than inferred from another BarraCuda capacity.A compatible SATA data connection, power connection and suitable 2.5-inch bay are required.
