Seagate BarraCuda 2.5-inch HDD Spec and Price in Brazil
SATA1TB5400 RPM
The 2.5-inch BarraCuda is Seagate's laptop and SFF hard drive: 5400rpm, a 128MB cache, and 7mm height that fits notebook bays and portable enclosures, per the Seagate data sheet. Sequential throughput is 110-140 MB/s depending on capacity — the honest ceiling of 2.5-inch mechanics, well under the SATA III bus limit. It carries a two-year warranty and is the bulk-capacity option for older laptops and console storage expansion.

Commonly praised
- At launch it was the highest-capacity desktop hard drive available, with a large cache.

Commonly criticised
- Fell behind hybrid drives in the read-heavy gaming trace, and read speeds were only average.
