The TOSHIBA DT1ACA200 is the 2TB variant of the DT1ACA series that features 1TB per platter technology. All the models in the series feature a 7200 rpm spindle and SATA 6 Gb/s interface . The biggest difference is in the size of the buffer. The 500GB and 1TB drives feature a 32 MB buffer and the 2TB and 3TB drives are equipped with a 64MB buffer. We recorded sequential read and write speeds of 133MB/s and random speeds of 124.5MB/s.
CrystalDiskMark and SiSoft Sandra logged slightly higher sequential speeds-145MB/s read and 141MB/s write. The random read and write speed logged by SiSoft Sandra was quite low at 77MB/s and 81MB/s respectively. If you have already planned to go in for a 1TB hard drive to build/upgrade you PC, buying this drive for a few hundred Rupees more would be a wise decision.
