Solid State Disk (SSD) to Replace Your Hard Drive



Think you’re staying on top of the game with your spiffy new 5,400RPM or 7,200RPM hard drive in your Notebook? Think again! Oh the changes in technology move so fast that sometimes it can be just downright painful!

Today:

Recently there has been a lot of interest among mobile computing enthusiasts regarding hard drive speed, performance and its affect on battery life. Whilst most of the world’s notebook computers house hard drives spinning at 4,200RPM (4,200 rotations per minute), the industry is quickly moving forward. The adoption of drives spinning at 5,400RPM and even 7,200RPM is starting to take hold of the mobile computer industry. As processors are hitting the wall in performance boosts due to heat and battery life issues, the next logical move in the seemingly unquenchable thirst for speed has been a focus on hard drives, bus speeds and RAM.

In looking at the great hard drive dilemma, the industry seems to be pointing mobile users into the direction of the 5,400RPM speed drives. The transfer rate advantage of these drives over the former 4,200RPM types is significant while the impact on overall battery life in mobile devices is negligible. Moving to the 7,200RPM drives at this time is not a popular choice (at least in the thin and light) notebook category, though some power users are going for this option in desktop replacement models.

Tomorrow:

We have talked “RAM” and “RPM” so how about we throw yet another acronym at you? “NAND”. NAND is a type of flash memory (similar to what you use in a digital camera). It is a very low power, permanent (allows read and write functionality) storage solution. Recently on June 17th, Samsung Electronics announced a NAND-based hard drive replacement. Calling it “the world’s first Solid State Hard Drive”, this new storage device boasts a power consumption of less than 5% needed for a conventional hard drive. Even more exciting is that this new type of hard drive benchmarks a performance of 150% that of standard hard drives! The SSD has no moving parts, so the need for “shock mounted” drives or the worries of hardware failure will no longer be issues of concern. Finally, the SSD type of drive will cost significantly less than the cost of drives today.

So what’s the catch? Not much with the exception that NAND-based drives are curently limited to only 16GB sizes. But just like everything else in the industry, it will only be a matter of time before we see improvements. The new SSD technology has been aimed at Tablet PCs and sub-notebook markets.
