Discover how Fibre Channel and iSCSI compare when it comes to meeting SAN performance, ease of use, manageability, total package and TCO requirements.
When iSCSI-based storage arrays first appeared in 2003, the technology was touted as a low-cost, few-frills alternative to Fibre Channel, the reigning king of the block storage hill. But that distinction quickly faded as leading data storage vendors joined the upstart array purveyors and added iSCSI storage to their product offerings. It wasn't long before the either-or arguments were replaced with considerations about which form of block storage would be the best fit for particular apps and environments.
Since the introduction of flash memory, the end of HDD has been predicted again and again - but the classic storage device persists and remains the standard in many application areas.
According to Trendfocus, 259 million HDDs were shipped last year -
a case in point. Their total capacity reached 1.338ZB, an increase of
almost one-third compared to 2020. Never before have HDDs been shipped
with more combined storage capacity.
Here is Toshiba's view on which HDDs are indispensable today and will
remain so in the coming years.
Online storage in core and cloud
data centres: Digital services now permeate almost all companies
and large parts of society. Whether it's Industry 4.0 environments,
connected vehicles, streaming platforms or social networks - the huge
and ever-growing volumes of data are stored on HDDs in data centres.
A Toshiba exec has argued that hard disk drives are essential to store data in several market areas because SSDs are ill-suited to the job, costing more and with limited manufacturing capacity.
Citing TrendFocus numbers, Toshiba Electronics Europe exec Rainer Kaese said: '259 million HDDs were shipped last year - a case in point. Their total capacity reached 1.338 zettabytes, an increase of almost one-third compared to 2020. Never before have HDDs been shipped with more combined storage capacity.'
That is so but the unit shipment numbers are flat. Statista says 258.9 million units were shipped in 2021, which was 2 percent less than 2020's 260.3 million units. Back in 2010, there were 650 million disk drives shipped.
