SSD vs HDD ?

Are you looking for a way to increase the performance of your notebook?  Then upgrading the storage is often an easy and worthwhile way to boost the speed of your laptop without buying a new computer.

PROS of SSD ( Solid State Drive)

  • Very short random access times – usually less then 0.1ms. For contrast, hard disk drives (HDDs) typically have access times of 5-10ms. An SSD should also have constant access time, whereas HDDs experience jitter depending on the prior location of the read/write head.
  • Drastically improved sequential transfer speeds, partly due to the parallelism of flash chips. New SSDs can max-out a SATA 3 Gbit/s bus; PCIe-based SSDs can reach over 700 MByte/s (5.6 Gbit/s).
  • No moving parts, very resistant to shock (many drives can withstand over 1000G), and absolutely silent operation.
  • Small form factor (most drives are 2.5″, some are PCIe which leaves more drive bays open), very light.
  • Good performance for both sustained and random reads/writes (mostly due to lower latency).
  • Not susceptible to magnetic fields (but are susceptible to radiation, like all other flash/DRAM).
  • Relatively low power consumption (flash-based SSDs only)

Installation Performance

The SSDs are clearly leading the pack here.  The 7200rpm hard drives took about 3 minutes more than the SSDs. As could be expected the 5400rpm Fujitsu came in slowest.

Windows Startup Performance

The SSDs are showing off their muscles here, booting in about 22 seconds.

File Copy & Software Launching Performance

Multitasking Performance

Battery life

Noise and Vibration

A nice benefit of SSD is the total lack of noise and vibration coming from them.
