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.
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….
