Nowadays solid-state drives (SSDs) are used to store frequently accessed data or applications both by client and server computers. By contrast, hard disk drives are used to store massive amounts of data since their capacity is larger, while the per-GB price is lower compared to SSDs. But SanDisk Corp. believes that in the coming years SSDs will get considerably larger capacities and will also significantly drop in terms of per-GB price.

Earlier this week SanDisk released Optimus Max SSD with 4TB capacity and SAS-6Gb/s interface that significantly outperforms mission-critical hard disk drives with 10K or 15K rpm spindle speed (up to 400MB/s sequential read/write, up to 75K/15K random read/write IOPS, 1-3 drive writes per day for five years) at the same time providing higher capacity as well. While a 4TB enterprise-class SSD is probably rather expensive, SanDisk does not plan to stop here: it wants to double capacities of solid-state drives every year or two and hopes to see 8TB and 16TB SSDs in 2015 and 2016, respectively.

"We see reaching the 4TB mark as really just the beginning and expect to continue doubling the capacity every year or two, far outpacing the growth for traditional HDDs," said Manuel Martull, product and solutions marketing director at SanDisk, in a conversation with Computerworld.

SanDisk reaffirmed that it hopes to release 6TB and 8TB Optimus Max SSDs in 2.5“ form-factor next year. It is logical to expect SanDisk to offer 16TB SSDs in 2016, if the company keeps the same pace.

Solid-state drives are going to continue being considerably more expensive than hard disk drives in 2015 – 2016 timeframe. However, if a company needs to store a large amount of mission-critical data within a limited amount of space in a datacenter and do it more efficiently from power consumption standpoint, then it may get 8TB or 16TB SSDs instead of large-amount of mission-critical HDDs.

In fact, SanDisk hopes that starting from 2017 enterprise-class SSDs and HDDs for mission-critical applications is going to cost about the same amount of money per gigabyte; hence, solid-state storage will be much more competitive than 10K or 15K hard drives.

It is rumoured that the newly-announced generation of 10K and 15K hard disk drives is the last generation of such HDDs. Partly this confirms expectations about per-GB price-parity between mission-critical HDDs and SSDs.

Competitive Cost per Gigabyte or it never happened. 1Tb SSD EVOs are currently the best value/performance in this regard. Can SanDisk do better? Hoping so!

I wouldn't hold my breath.
