Desktop HDD 4TB (2013)

This is Seagate's most recent hard drive and their first 4TB consumer offering. With a rotational speed of just 5,900 RPM it's significantly slower than the 7,200 RPM Barracudas that it supersedes. The lower rotational speed results in approximately 10% slower sequential transfer speeds and longer access times which make this drive less suitable for use as a system drive. With peak 4k read/write speeds of 0.76/1.2 MB/s the 4TB HDD.15 lags the group leaders significantly. The HDD.15 is a far better candidate for use in a NAS (Network Attached Storage) where factors such as power consumption and cost per GB are more important than outright speeds. To conclude, the HDD.15 has a relatively disappointing small file 4K performance profile but it does offer a huge amount of storage at a very competitive price which makes it a good candidate for use in a NAS. ^{[Aug '13 HDrivePro]}
