Seagate BarraCuda Pro 12TB Hard Drive Review


Performance w/ CrystalDiskMark and ATTO

CrystalDiskMark v5.2.2

CrystalDiskMark is a small benchmark utility for drives and enables rapid measurement of sequential and random read/write speeds.

Seagate BarraCuda Pro 12TB versus 10TB CrystaDiskMark

On our test system we found that the Seagate BarraCuda Pro 10TB hard drive was able to top out at 244 MB/s read and 232 MB/s write in the sequential test whereas the new BarraCuda Pro 12TB hard drive topped out at 250 MB/s read and 248 MB/s write! These are some pretty decent performance gains seeing how both are 7,200 RPM desktop hard drives with the same amount of cache (256MB multisegmented). The 4K random read and write scores are no where near that of a a modern SSD, but these large drives will likely be used as secondary storage drives rather than a boot drive with an OS on it.

ATTO Disk Benchmark v3.05

ATTO is one of the oldest hard drive benchmarks that is still used today. ATTO measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and places the data into graphs that you can easily interpret. The benchmark test was run with file sizes from 0.5kb through 64MB with the total length being 256mb.

Seagate BarraCuda Pro 12TB versus 10TB ATTO Disk Benchmark

Benchmark Results: The Seagate Barracuda Pro 10TB HDD drive hit 245 MB/s read and 235 MB/s write and the new BarraCuda Pro 12TB peaked at 253 MB/s read and 247 MB/s write. These are some solid gains on ATTO Disk Benchmark, which is one of the go to benchmarks in the storage industry. Who thought that we’d be getting around 250 MB/s read and write speeds from a hard drive?
