Mercedes Benz MB Star diagnostic software XENTRY / DAS for MB Star C3 or MB SD connect C4 always get nice reputation in terms of diagnostics and programming functions. But these days, more and more people began to complaint about its terrible running, especially for the running speed. And here, mbstartool.com offers the MB SD C4 diagnostic system with software SSD (solid drive) version.which will work like a charm to help you get rid of your disappointment.

Speed
|
HDD has higher latency, longer read/write times, and supports fewer IOPs (input output operations per second) compared to SSD.
|
SSD has lower latency, faster read/writes, and supports more IOPs (input output operations per second) compared to HDD.
|
|
Heat, Electricity, Noise
|
Hard disk drives use more electricity to rotate the platters, generating heat and noise.
|
Since no such rotation is needed in solid state drives, they use less power and do not generate heat or noise.
|
|
Defragmentation
|
The performance of HDD drives worsens due to fragmentation; therefore, they need to be periodically defragmented.
|
SSD drive performance is not impacted by fragmentation. So defragmentation is not necessary.
|
|
Components
|
HDD contains moving parts – a motor-driven spindle that holds one or more flat circular disks (called platters) coated with a thin layer of magnetic material. Read-and-write heads are positioned on top of the disks; all this is encased in a metal cas
|
SSD has no moving parts; it is essentially a memory chip. It is interconnected, integrated circuits (ICs) with an interface connector. There are three basic components – controller, cache and capacitor.
|
|
Weight
|
HDDs are heavier than SSD drives.
|
SSD drives are lighter than HDD drives because they do not have the rotating disks, spindle and motor.
|
|
Dealing with vibration
|
The moving parts of HDDs make them susceptible to crashes and damage due to vibration.
|
SSD drives can withstand vibration up to 2000Hz, which is much more than HDD.

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.
Summary: 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 Mercedes-Benz vehicles.. |
