Just how much corporate faith is being put into SSD technology? Gartner predicts that up to 25% of data centers may use all-flash arrays for primary storage by 2020, with ROI of under six months in some cases.
Organizations are processing extreme amounts of input/output operations thanks to SSDs. As these drives get faster and more affordable, we’ll only see more of them in enterprise data centers. Other factors, including IOPS per watt and capacity and performance per rack, also make SSDs attractive to data center pros. It’s safe to say the future is bright for these non-spinning disks.
Here are 4 SSD predictions for this year and beyond:
1. Capacities will blow your mind
Just when IT pros were nerding out over Samsung’s 16TB SSD, Seagate announced its own 60TB behemoth. Companies have long ditched low-capacity drives for the cost savings of 256GB, 512GB and 1TB SSDs—but this is next-level capacity. Some larger data centers are already investing in multiple TBs, so it’s only a matter of time before 60–100TB SSDs hit the mainstream market.
2. Density will increase
HDDs used to reign supreme when it came to the amount of memory that can be packed into a particular drive form factor. Not anymore. When you leverage SSDs to pack more storage into the same space, it translates into fewer servers, less power, less cooling and less data center space required. With capacity increases, enterprises are seeing this as a measurable approach to lowering TCO.
3. Costs will drop and ROI will come earlier
We expect a market correction to reverse the recent flash memory shortage that threw fabrication plants into a frenzy, resulting in higher costs. The shortage is expected to clear up this year, which will place pricing to just a few pennies per gig. Although SSDs are more expensive than HDDs, the cost for both should decrease and ROI should be recognized earlier. Fun fact: In 1981, hard drive prices were as high as $500,000 per gig.
4. NVMe will help you reach “full flash potential”
We recently learned that a petabyte of data can be crammed into a single 1U server rack—thanks to NVMe technology. This new form factor optimizes rack efficiency, delivers unparalleled space-efficient capacity and simplifies serviceability. The all-flash NVMe solution boasts more than double the capacity per rack unit and is 40% more thermal efficient.
NVMe has been tempting data center operators around the globe with its groundbreaking method of accessing storage media. We predict that NVMe will evolve from “wish list” to “must have,” as it continues to lower power consumption by reducing latency in the host software stack—all while increasing input/output operations.
