Seagate Barracuda 7200.10 750 GB SATA Hard Drive

Specifications and Perpendicular Recording


Seagate list the Barracuda 7200.10 as "the Highest Capacity 3.5-inch disc drive". Sustained data transfer is listed as 78Mbytes/sec, with a spin speed of 7200RPM.

Quick Features:

We'll see if the drive lives up to its claimed speed later on.

Seagate offer a 5 year Warranty on this drive. It's always nice to know that your drive will be replaced if anything unseen happens to it. This does not extend to your data, of course.

The Seagate has Native Command Queuing as one of its features. This feature means that the drive prioritises it's access requests to best utilise the way in which it is spinning. This isn't so useful for one user workstation, unless you are heavily multitasking the HDD. However, in situations such as a home media server, this leads to better response time for the PC's giving the requests.

Perpendicular Recording

Seagate's 7200.10 features perpendicular recording. This is a pretty exciting feature in a Hard Drive. Perpendicular recording allows the drive to record the data vertically onto the drive surface. This is compared to normal drives that record in a linear fashion. This means that the drive permits much higher data density per square inch. The drive platters are slightly thicker than traditional hard drives, with a soft underlayer.

Another advantage to perpendicular recording is that where data from longitudinal recording is very dense, this can cause the particle magnetic orientation to flip and this can cause data corruption as a result. This means that longitudinal hard drives have to leave a larger space between the data as if it gets too dense this will cause data loss. Perpendicular recording means that the data stored vertically does not get as dense. This means that it can record far denser data. It is claimed that perpendicular recording produces 1 Tb/in², 5-10 times that of longitudinal recording, which maxes out at 100 to 200 Gb/in².

your right the one in the pic is the IDE Version but there is also the SATA II Version.

All mobos support it even if it is sata 2 and the mobo is only sata 1 but int that case it lacks the features of sata 2Quote
