SD vs. SSD

An SD card is removable flash memory, much like a USB stick (thumb drive), it just fits into smaller slots, like in a digital camera, or phone. SD stands for secure digital.

SSD stands for solid state drive and is a hard drive based on flash memory technology just like the an SD card, except it usually holds much more data. SSD differs from a conventional hard drive. It has no moving parts, it is much faster and lighter, does not use much energy, and does not emit heat.

Super Storage

Computers are getting smaller and so is storage, but not data. Businesses are being forced to store huge amounts of data. The latest product is the 60TerraByte SAS solid state device from Seagate, the world's largest capacity solid state drive and it fits into a standard 3.5 inch standard hard disk drive slot.

The drive is aimed at data centers. It has twice the density and four times the storage of its nearest competitor. The capacity shows room for 400 million photos or 12,000 DVDs.

"Given the demands on today's data centers, optimal technologies are those that can accommodate an immense amount of data as needed—and without taking up too much space. As such, we are constantly seeking new ways to provide the highest density possible in our all-flash data center configurations," says Mike Vildibill, vice president of Advanced Technologies and Big Data at HP Enterprise.

Seagate has not released pricing details on the 60TB SAS SSD, but it has said the drive will hit the market during 2017.

Flash Drives Getting Smaller

The NAND (not and) flash technology that Toshiba introduced in 1989 (130nm or nanometers), making thumb drives, SSDs, (solid state drive) and smartphone memory, has finally reached a development dead end. Toshiba and other major manufacturers of 15 nm NAND flash are stopping new development and focusing development on 3D NAND.

For comparison, a strand of human DNA is 2.5 nm in diameter, and there are 25,400,000 nanometers in one inch. 1 centimeter = 10,000,000 nanometers.

Intel says it will be able to fit 1TB (terabytes) on a card just two millimeters thick in an object half the size of a postage stamp.

A square inch drive with a Terabyte of capacity can contain more bits than the Milky Way has stars (about 200 billion to 400 billion stars as estimated by astronomers). Obviously, when it comes to computers, size matters and smaller is better. Incidentally, My blog spoke of terabytes in 2010 LINK
