SSDs are currently the first choice for a high performance at very small dimensions. The SSD prices are getting lower, so that now even 256 GB or 512 GB are getting affordable. But those who would like to equip their notebooks with a bigger drive like e.g. 1 TB, will probably buy a conventional hard drive. And even for desktop PCs or servers a 2.5-inch hard drive can make sense, which Seagate is showing us with their fast Seagate Constellation.2 1TB 7200 U/Min Enterprise hard drive. Today, we take a look at the Seagate ST91000640NS and tested it with the latest firmware SN02. Unfortunately we could not test, if this hard drive is really running 1.4 million hours without a failure, but the MTBF reliability is approx. 160 years at 24/7 operating. But let us test the performance of the Seagate Constellation.2 1TB SATA3 hard drive and compare the results with the previously tested solid state drives and hard drives.
Thanks for the support …
