HDD (Hard Disk Drive): storage center for
SSD (Solid State Drive): same thing as a
hard drive, but with no moving parts
Example: USB flash drive, internal memory
on cell phones and cameras
A hard drive is cheap and that’s why
consumers prefer that option.
Typical price range for a HDD is $74.99 to
$120.99 for a terabyte (1024 GB).
The typical cost of a HDD is about 7 cents
per GB which shows its extreme
Performance of a HDD: Base speed of a
low-end hard drive is 5400 rpm
(revolutions per minute) and a high-end
hard drive would be 7200 rpm.
The faster the disk spins, the faster the
computer performance will be. In other
words, the boot time and/or loading
applications will be faster, hence more
Itwill boot the operating system much
quicker and applications will appear
much faster since it has no moving parts.
Compared to the HDD, SSD produces little
to no heat.
Price: Ranges from $130 for 40 GB to $800
for 256 GB. This gives us an estimated cost
of $3 per GB.

Hybrid Hard Disk Drive
HHDD combines the disk of a HDD and the
memory chips of a SSD.
Combines the performance of the SSD with
the price and capacity of the HDD, hence
the term Hybrid Hard Disk Drive.
HHDD uses 128MB or more of high speed flash
memory (embedded in hard drive).
So, when booting a PC, operating system
loads data from flash memory first, speeding
up boot time and also removes need to
quickly spin up the drive (saves power
Expect HHDD to come out in end of 2010 or
beginning of 2011.
Much cheaper than SSD
