It feels like I just participated in my billionth solid state storage product launch. In fact, I have participated in quite a few since the year 2000. In almost chronological order, here are the solid state storage systems I can recall launching into the market. If you are a solid state storage historian, you should pay close attention to the following table:
Some additional observations on trends over this period:
- Prices have come down from $5,000/GB in 2000 to below $10/GB in 2015. That means solid state storage costs 0.20% of what it cost 15 years ago.
- Capacity per rack unit in 2000 was 10 GB/RU. Capacity per rack unit in 2015 is 28,500 GB/RU. In the past 15 years solid state storage density has increased by 2,850x. Mind-blowing, really.
- Latency exhibited by the RAM-based products was very consistent and low over the 10 year period. Considerable cost, density, and persistence advantages forced a move to NAND flash memory in 2007, but latency for the flash-based products has remained consistently below 250 microseconds over the last 8 years.
- The continual trend to lower cost per bit NAND technologies (SLC to eMLC to MLC).
- There has been a consistent investment in enhanced data protection that started with protecting the memory in RAM using Chipkill and subsequently Variable Stripe RAID, a patented TMS technology.
- TMS, and now IBM, has improved RAS features as the systems evolved, from requiring two units for data protection to requiring only one highly available system.
- We’ve recently seen more demand for advanced storage services as the market for all flash arrays broadened from application acceleration to Tier 1 disk replacement.
Looking to make predictions about the future of solid state storage? A quick glance at the rate of product innovation and the reasons for change over the last 15 years can tell you much about how the industry will continue to evolve.
I always enjoy your posts Woody and this one is no exception (especially since I remember a few of those launches!). Hope all’s well and if you’re ever in the UK do let me know – it’d be nice to meet up over a drink.
I think it was more than a few that you helped with! You were our key to marketing in Europe. Thank you for everything you did for TMS.
