Consumers who are in the market for hard disk drive (HDD) storage have a variety of capacity options to consider, all of which provide different cost per GB ratios.
Current hard drive pricing is still higher than it was towards the beginning of Q3 last year, as the industry is feeling the effects of the flood that hit Thailand and crippled hard drive production.
That said, hard drive pricing is steadily reducing towards pre-flood levels, and HDDs provide a much cheaper storage alternative to using Solid State Drives (SSDs).
Another consideration to bear in mind is that 3TB HDDs are no longer the highest capacity drives available. 4TB drives were announced earlier this year by Hitachi, and have started appearing on local distributor price lists.
Prices for the comparison below were sourced from a range of retailers, including: PC International, a Johannesburg-based retailer with countrywide shipping; and online retailers Prophecy and Sybaritic.
|PC International price||R760||R987||R967||R1,214||R1,717|
|PC International cost per GB||R1.52||R0.99||R0.65||R0.61||R0.57|
|Prophecy cost per GB||R1.64||R1.01||R0.75||R0.62||R0.61|
|Sybaritic cost per GB||R1.55||R0.99||R0.73||R0.59||R0.93|
Understandably, the cost per GB decreases as the capacity of the hard drive increases, with 3TB drives offering the best cost per GB on average across a range of South African retailers.
There is also a 33 percent decrease in the cost per GB between 1TB and 1.5TB drives, going from 99c per GB to 65c per GB using PC International pricing.
Beyond this decline, the decrease in price per GB between 1.5TB and 2TB drives is 6.1 percent. 3TB drives save a further 6.5 percent per GB over the price of 2TB drives.
3TB drives offer the best price per GB out of current hard drive offerings in South Africa. If consumers are uneasy about storing such a large amount of information on a single drive, 1.5TB and 2TB drives still offer a significantly better pricing per GB than 500GB and 1TB drives.
