WDC: No SSD/HDD Crossover

WDC HDD vs NAND Price per GB 10X GapThose who have been reading posts on The SSD Guy blog for some time have often heard me explain that SSD prices will not fall below HDD prices anytime soon.  Last week Western Digital shared a roadmap that shows that we can expect for there to be a sizeable price gap between the two technologies at least through 2028.

Let me stop for a moment to point out that Western Digital Corp, or WDC, no longer has any reason to take sides in the HDD vs. SSD battle now that the company has acquired SanDisk, a leading SSD maker.  Even before that, WDC’s HGST business has been the market leader in SAS SSDs for a number of years.  WDC doesn’t take sides in arguments about SSDs vs. HDDs.  Instead the company stands ready to sell whichever one the customer finally decides to use.

This post’s graphic comes from a chart that WDC used on October 11 when introducing its new MAMR head technology, which the company expects to propel HDD capacities up, and HDD price per terabyte down, for a number of years.  To create this chart WDC’s HDD team joined forces with the SanDisk flash team to project both HDD and NAND price per terabyte for the next 11 years.  The most important conclusion is that Continue reading

Big New HDDs Indefinitely Postpone SSD/HDD Price Crossover

HGST's 10TB Shingled HDDEarlier this month Western Digital’s HGST division invited The SSD Guy to a launch of a number of products.  On the HDD side there were:

  • 6TB air HDD, HGST’s last air-filled enterprise HDD
  • 8TB helium HDD, an incremental upgrade of last year’s 6TB helium HDD
  • 10TB shingled helium HDD (pictured)

I view these as very solid evidence that HDD costs will continue to stay an order of magnitude cheaper than SSD costs, thwarting the price-per-gigabyte crossover that others have been predicting for years.

In fact, since my last post on the price crossover in 2011, very little has changed.

It’s safe to assume that the HDD industry will Continue reading
