This is where SSDs shine. An SSD-equipped PC will boot in seconds, certainly under a minute. A hard drive requires time to speed up to operating specs,
and will continue to be slower than an SSD during normal use. A PC or Mac
with an SSD boots faster, launches apps faster, and has faster overall
performance. Witness the higher PCMark benchmark scores on laptops and
desktops with SSDs, plus the much higher scores and transfer times for
external SSDs versus HDDs. Whether it’s for fun, school, or business, the
extra speed may be the difference between finishing on time or failing.
Maximum and Common Capacity:
Dell D630 SSD 256GB, HDD 500GB
Basically, the more storage capacity, the more stuff or application
you can hold on your PC. While the (Internet) cloud may be a good
place to share these files among your phone,tablet, and PC, local
storage is less expensive, and you only have to buy it once.
Because of their rotary recording surfaces, HDD surfaces work
best with larger files that are laid down in contiguous blocks.
That way, the drive head can start and end its read in one continuous
motion. When hard drives start to fill up, large files can become
scattered around the disk platter, which is otherwise known as fragmentation.
While read/write algorithms have improved to the point that the effect
is minimized, the fact of the matter is that HDDs can become fragmented,
while SSDs don’t care where the data is stored on its chips, since there’
s no physical read head. Thus, SSDs are inherently faster.
An SSD has no moving parts, so it is more likely to keep your data
safe in the event that you drop your laptop bag or your system is shaken
about by an earthquake while it’s operating. Most hard drives park their
read/write heads when the system is off, but they are flying over the drive
platter at hundreds of miles an hour when they are in operation. Besides,
even parking brakes have limits. If you’re rough on your equipment, an SSD
Hard drives are simply more plentiful. Look at the product lists from
Western Digital, Toshiba, Seagate, Samsung, and Hitachi, and you’ll see
many more HDD models than SSDs. For PCs and Macs, internal HDDs won’t be
going away completely, at least for the next couple of years. You’ll also
see many more HDD choices than SSDs from different manufacturers for the same
capacities. SSD model lines are growing in number, but HDDs are still in the
majority for storage devices in PCs.
Because HDDs rely on spinning platters, there is a limit to how small they
can be manufactured. There was an initiative to make smaller 1.8-inch spinning
hard drives, but that’s stalled at about 320GB, since the phablet and smartphone
manufacturers have settled on flash memory for their primary storage. SSDs have
no such limitation, so they can continue to shrink as time goes on. SSDs are
available in 2.5-inch laptop drive-sized boxes, but that’s only for convenience.
As laptops become slimmer and tablets take over as primary Web-surfing platforms,
you’ll start to see the adoption of SSDs skyrocket.
Even the quietest HDD will emit a bit of noise when it is in use from the drive
spinning or the read arm moving back and forth, particularly if it’s in a system
that’s been banged about or in an all-metal system where it’s been shoddily
installed. Faster hard drives will make more noise than slower ones. SSDs make
virtually no noise at all, since they’re non-mechanical.
Overall: HDDs win on price, capacity, and availability. SSDs work best
if speed, ruggedness, form factor, noise, or fragmentation (technically
part of speed) are important factors to you. If it weren’t for the price
and capacity issues, 2016.03 SDconnect C4 software running in SSD would be
the winner hands down, the idealest tool for diagnostics and programming on
