21 years of evolution of the hard drive (HDD) 3.5 “: 1991 vs. 2012
From Tom’s Hardware comes an interesting article comparing the characteristics of an existing hard drive compared to the characteristics of a hard drive manufactured in 1991, to enlighten us about the great developments that have had hard drives in both its ability to as Storage performance.
As a representative of hard drives this year have the hard drive 4TB Western Digital Caviar Black (WD4001FAEX) and as a representative of the year 1991 we have the hard drive maxtor 7040A 40MB (if MegaBytes, believe it or not, not a bug fingering), both hard drives among the best hard drives of 3.5 “of his time.
The Maxtor 7040A 40MB hard disk had a rotational speed of 3500 RPM, IDE interface (PIO), 32KB of cache, transfer rate of 600 to 700 KB / s (similar to a CD-ROM 4X) and latency 27 milliseconds, while the hard drive 4TB Western Digital Caviar Black (WD4001FAEX) has a rotational speed of 7200 RPM, SATA-III interface, 64MB cache, a transfer rate of 128 MB / s and a latency of 4.2 milliseconds.
Exposed features both hard drives we have 1991 to 2012 hard drives have increased their capacity over 100,000 times (40MB vs 4TB), while its yield is 182 times higher (0.7 vs 128 MB / s).
