The drive will be costly; SanDisk said it will cost $600 more than a regular hard drive — which means the price will be about $800 to $1,000.
Why is SSD better?
There are a few reasons solid state flash is superior to the traditional hard drive that uses a mechancial head to read data from a platter:
- Fewer moving parts so less hard drive failures
- Lower power consumption, consumes 0.4 watt during active operation compared to 1.0 watt of regular hard drives
- Faster access to data, sutained reads of 62 MB/s. In some burst instances an SSD can be 100 times faster than a mechanical hard drive
SanDisk indicated that using that a drive loaded with Windows Vista Enterprise fully booted in a very fast 35 seconds. Of course, these numbers are all in house benchmarks quoted by SanDisk so they need to be taken with a grain of salt.
The 32 GB SanDisk drive is available immediately to manufacturers (OEMs), but there is no indication as to whether the drive will be sold through consumer channels.
