These three parameters, initial access time
, sequential access only, and a perceived higher management cost represent the next frontier for the Nearline and mass storage providers to address.
The low-voltage memory chips offer access times
as fast as 25 nanoseconds (25 ns), the industry's fastest.
Such a system potentially provides 1 gigabyte capacity, microsecond access times
, and is not unduly expensive.
Yet every bit of it is completely available to end users through their normal file browse and search utilities with remarkably short file access times
that range from less than a second to about a minute.
In pipelined mode, the devices operate with clock rates up to 250MHz and with clock access times
less than 2.
Since deployment, the Seoul server has become the most active outside of the USA, now processing over 1000 queries a second; while the Beijing server has provided a 15-fold improvement in DNS access times
to local Internet users.
I do have some concerns because capacities are increasing faster than access times
and I wonder how much data ought to hang out on a single spindle.
Benefits Include Standardized Worldwide Access Times
The rollout of PSS' breakthrough low-power solution comes just three months after the company began shipping another industry first -- an ultra high-speed flash memory featuring random access times
of less than 20ns, the fastest 1 Mb random-accessible flash memory in the world.
