Not surprise at all...
Solid-state drives (SSDs) are rapidly gaining in popularity not only among consumers, but also in the enterprise. Many IT professionals are recognizing the benefits of SSDs and replacing hard disk drives (HDDs) in key server applications. However, there are loads of enterprises, who rely on datacenters with hard drives. Samsung believes it is time for a change.
Everybody knows that SSDs are faster, more reliable and efficient than hard disk drives. However, many believe that SSDs are also very expensive and their cost will not bring benefits that will justify the spending. According to Ryan Smith, senior product manager of SSD marketing at Samsung Semiconductor, many of the price-related things about solid-state dries are now myths.
With that in mind, it is time to consider all the pros and potential cons of SSDs for enterprises. According to Samsung, these are key reasons why the enterprise market is moving towards SSDs over HDDs:
- Speed: Hard drives have spinning disks that can do a max of 400 IOPS. SSDs can go up to 101,000 IOPS or faster. This is equivalent to 250 spinning disks! Simply put, SSD performance cannot be matched by spinning disk – not by a long shot.
- Efficiency: Power consumption is significantly lower in SSDs. I’m speaking about idle power as well as active power. A recent Microsoft TPC-H study showed overall system power savings of 94% to be gained from using an SSD.
- Reliability: Enterprise SSDs provide superior reliability. For example, MTBF (mean time between failure) for HDD’s is 1.6 million hours; SSDs provide 2 million hours.
- Consistent Performance: SSDs have no moving parts and, therefore, are not susceptible to RVI (rotational vibration interference). SSDs are free from the undesirable performance dips or drive failures induced by RVI, which are one of the hardest problems to troubleshoot in the enterprise space.
- Pricing: SSDs were traditionally priced in a way that left them unaffordable for many system architectures. With dropping price of NAND flash, that is not the case anymore. Advances have been made in underlying NAND flash and controller technologies that have resulted in lower overall pricing, which has in turn moved IT professionals to not only replace HDDs but to also invest in higher SSD capacities.
- Cost Advantages: In many cases, especially for apps that do not require huge amounts of capacity (such as boot drives for servers), low-capacity SSDs can actually cost less than high-capacity SSDs.
