Hard disk drives (HDD) are made primarily of a magnetic platter.  A mechanical arm moves across the platter as it spins to read/write 1’s and 0’s to platter.  The process of reading and writing the data is very mechanical on the HDD.

Solid State Drives (SSD) have no mechanical or moving parts and the data is stored on microchips.  This makes the SSD drives more efficient at reading and writing data to and from the drive.  Hard drive failures are reduced greatly by switching to SSD drives.

The SSD drive read and write speeds are much faster than those of the HDD drive.  This will decrease the computer boot time and should improve the performance of the machine greatly.

The above picture illustrates the physical difference between the two types discussed

The biggest question often overlooked: How long does an SSD last?

There are three SSD storages are available: Single Level Cell (SLC), Multi-Level Cell (MLC) and Triple Level Cell (TLC). It is simple logic that the more data saved per cell is saved, the higher the wear level. When only reading data, an SSD will not wear out. The life of an SSD depends on the write and delete operations.

This paper covers the basic comparison of the two technologies and touches on the different levels of SSD. Next month’s entry will break down the differences in Solid State Drive offerings.

Common sense leads us to believe the faster the clock speed the better CPU but that could be a costly decision. Intel Corporation has a strong hold on the CPU market in the x86 arena and offers the user so many choices it can be daunting. Let’s try to make some sense out of the different x86 CPU available and what gives users the “most bang for the buck.”
