SSD is all the rage in the storage industry. Very exciting technology for sure and just now going Prime Time in the enterprise. But the rise of SSDs does not correlate with a fall for hard drives.
In fact, it looks like hard drives have quite a bit of life left in them.
A new study by Dr. Mark Kryder and Chang Soo Kim at Carnegie Mellon on the state of storage technology in 2020 yields some surprising findings:
- A 2.5″ disk drive will likely store 14 TB for about $40
- Hard drives look to remain considerably less expensive than any competing technology
- Flash memory will be the next best technology, but will be battling technology limits at about that time
- Two other technologies to watch: phase change random access memory (PCRAM) and spin transfer torque random access memory (STTRAM)
The question to ask is not “Which technologies will replace hard drives?”, but “Which technologies will complement hard drives?”
