vs. Storage Technology Demystified By:


Слайд 1

Confused about all the hype surrounding SSDs?


Слайд 2

We don’t blame you. 3


Слайд 3

What you do know is…


Слайд 4

Your computer is driving you @#%!& crazy. why are you taking so long to boot?!!?


Слайд 5

Who? Me? And it’s most likely ‘cause of this thing… Your hard drive.


Слайд 6

And no, don’t defrag your hard drive… …AGAIN!!! (We know what you were thinking) There’s only so much defragging can do to enhance storage performance…


Слайд 7

What does yours say? Defrag won’t save you from… …the lag?


Слайд 8

Instead, consider upgrading to a solid state drive.


Слайд 9

Wondering why? Glad you asked…


Слайд 10

SSDs are More…


Слайд 11

Because SSDs have no moving parts Hard drives consist of various moving parts making them susceptible to shock and damage, while SSDs use a non-mechanical design of NAND flash mounted on a circuit board and are shock resistant up to 1500g/0.5ms. platters spindle r/w head cache nand flash memory actuator arm controller arm pivot actuator Shock resistant up to 350g/2ms Shock resistant up to 1500g/0.5ms


Слайд 12

And because SSDs have no moving parts…


Слайд 13

SSDs are Faster. Period. SSDs can be up to 100 times faster resulting in rapid data access and system acceleration. HDDs inherently take longer to access data because of their need for the disks to spin while the HDD head seeks out the data requested by the host. On the contrary, any part of the SSD can be accessed instantaneously. 14


Слайд 14

In fact…

Слайд 18

Leading to a better, more responsive PC experience. Take gaming for instance… 19

Слайд 22

And the fact that SSDs have no moving parts leads to more awesome benefits aside from performance…


Слайд 23

SSDs are more Reliable. One universally accepted metric for measuring SSD reliability is known as an “annual failure rate.” Exhaustive studies have shown that SSDs have an annual failure rate of tenths of 1%, while the AFRs for HDDs can run as high as 4 to 6 percent. source: networkworld.com


Слайд 24

SSDs use Less Power 6 – 7 Watts vs. 2 – 4 Watts Which can lead to up to 30 more minutes of battery life for notebook users. source: storagereview.com


Слайд 25

SSDs are cooler . Thanks to no moving parts and completing tasks faster, SSDs run at cooler temperatures. 34 – 44 °C 26 – 30 °C source: anandtech.com; techreport.com (case testing)

SSDs are Lighter . 48 grams Lighter OCZ Trion 480GB SSD 113 grams Mobile 2.5-inch 500GB Hard Drive Making mobile users who lug around their notebook happy.
