Solid-state disk (SSD) drives are all the rage among techies. The drives use non-volatile NAND flash memory, meaning there are no moving parts. Because there is no actuator arm and read/write head that must seek out data on a platter like on a hard disk drive (HDD), they are faster in reading and, in most cases, writing data.

Toshiba has begun volume shipments of solid-state drives ranging up to 512GB in size, as these hyper-fast storage options bulk up on capacity.Drives are also offered in 64GB, 128GB, and 256GB capacities and are built on a 43-nanometer manufacturing process using multi-level cell (MLC) technology. MLC technology allows drive makers to increase capacity while keeping production costs under control.

All drives come in either a 1.8-inch enclosure, typically used in ultraportable laptops, or a 2.5-inch housing, the standard size for mainstream laptops.

Now why to go for SSD’s:
  • This seems to be the future.
  • Faster access to data.
  • Faster boot time.
  • No Moving parts unlike the HDD, hence they are more robust.
  • No acoustic problems, almost zero noise.
  • Power Consumption is less, hence more battery life.When failures occur, they tend to happen predominantly while writing, or erasing cells, rather than upon reading cells. With magneto-mechanical drives, failures tend to occur while reading. If a drive detects failure on write operations, data can be written to a new location. If a drive fails on read, then data is usually lost permanently.
Now why not to go for SSD’s:
  • Its expensive compared to the sata hdd’s and the price difference is almost maintained through out, atleast for now.
  • Can go kaput on power surges, well this applies to the HDD’s as well.
  • The technology is still evolving and may need a few more years in R&D to come up with a technology which can deliver SSD’s with a price, atleast comparable to the HDD’s.

    Conclusion:Hard Drives will soon become ancient by computer tech standards….
