The First SSD

Few realize just how long SSDs have been around.  In fact, Dataram introduced the Bulk Core SSD in 1976.

This 2-megabyte wonder, introduced in 1976, was said to offer speeds 10,000 times those of a fixed-head disk, while reducing power consumption, with no moving parts much like the SSDs of today.

Some may object to my calling this an SSD – and with good reason.  It didn’t use semiconductor memory technology, it used core memory.

Still, core memory was orders of magnitude faster than contemporary HDDs.

Move ahead 35 years to 2011.  The HDDs are smaller than the rack-width unit shown in the ad, as are the SSDs, but both have increased in capacity by 3-4 orders of magnitude, with performance improvements of a couple of orders of magnitude.  The mind boggles at the improvements the next 35 years should bring!

    I apologise, but could you give me the specs of the BULK CORE, compared to the modern SSDs, including its dimensions. i.e length, width and height. Thanks in advance 🙂

      DarkWing,

      I’m afraid that I don’t have anything about the device except for the advertisement shown in the post’s graphic.

      The physical dimensions would be the width and depth supported by a standard computer rack. You could estimate the height from the photo.

      Jim
