Western Digital could be preparing to take on the tape archive market using HDD (opens in new tab) technology as the company looks to solve the archive problem.
As reported (opens in new tab) by Block & Files which spoke with EVP and GM of the company's HDD business Ashley Gorakhpurwalla, businesses in the storage industry are considering adding another storage tier that will allow colder data and archive data to co-exist.
Typically companies have relied on tape storage (opens in new tab) as a means to store large amounts of data in the cheapest way possible. However, a new type of hard drive with more platters could present a compelling alternative to tape storage as it will allow data to be retrieved more quickly.
Given that Gorakhpurwalla spoke openly with Block & Files about Western Digital's archival data disk drive concept, it's likely that Western Digital and its customers have already begun discussing the idea.
In a memory-to-tape hierarchy diagram, CPU caches and DRAM have the highest cost with the lowest latency followed by storage-class memory, SSDs (opens in new tab), nearline HDDs and then tape at the very bottom. Archive HDDs though could be quite useful for business data that needs to be saved but doesn't need to be read often if at all.
Gorakhpurwalla explained to Block & Files that one of the ways that Western Digital (opens in new tab) and others in the storage business could create massive archive HDDs is by increasing the number of platters that make up a disk drive, saying:
“Think of a hard drive in a traditional sense, you know, the three and a half inch form factor with 9 or 10 platters [and] in the future 11 platters and … the [kind of] head stack that we have today. That’s a … combination of technologies and capabilities. Utilising … that toolbox then to go and be able to deliver a solution for different tiers in the datacentre … is part of our roadmap at Western Digital.”
By adding an additional platter, Western Digital could get a 2TB+ boost to drive capacity which would help when archiving large amounts of data. Although the company doesn't plan to launch 11-platter disk drives anytime soon, the idea is part of its roadmap going forward.
