Seagate releases 2.5" HDDs with up to 5TB capacities

Seagate has now released their new BarraCuda series 2.5" HDDs, offering capacities as large as 5TB, which is staggering for a 2.5" HDD. On the higher end, Seagate has also released their new 6-10TB BarraCuda Pro HDDs, which come with a 5-year warranty and cache sizes that are as large as 256MB.    

For their new 2.5" drives Seagate has utilised SMR, Shingled Magnetic Recording, technology in order to increase storage capacity by up to 25% by slightly overlapping newly written magnetic tracks. SMR technology will increase drive capacity but reduce the drives write speeds, though Seagate does say that these shortcomings are more than offset by this drive's use of a 128MB DRAM Cache buffer and their new Multi-tier Caching system.

The main downside of Seagate's new high capacity 2.5" drives is that most of them come in non-traditional form factors, with the 3TB and above drives coming with a Z-height (drive thickness) of 15mm, which is much larger than the 7mm or 9mm heights that most notebooks can currently accept. This will mean that most notebooks will not be able to use these high capacity drives, though they remain remarkably small for a drive of that capacity. 

The larger 3-5TB drives are intended to be used in the mobile HDD market, where they will be placed inside an enclosure for use outside of desktop or portable PCs, though the option exists to use them inside custom or OEM PC builds.
