NAND Flash Density Surpasses HDDs', But Price Is Still a Sticking Point (computerworld.com)

Lucas123 writes: With the introduction of 3D or stacked NAND flash memory, non-volatile memory has for the first time surpassed that of hard disk drives in density. This year, Micron revealed it had demonstrated areal densities in its laboratories of up to 2.77 terabits per square inch (Tbpsi) for its 3D NAND. That compares with the densest HDDs of about 1.3Tbpsi. While NAND flash may have surpassed hard drives in density, it doesn't mean the medium has reached price parity with HDDs — nor will it anytime soon. One roadblock to price parity is the cost of revamping existing or building new 3D NAND fabrication plant, which far exceeds that of hard drive manufacturing facilities, according to market research firm Coughlin Associates. HDD makers are also preparing to launch even denser products using technologies such as heat assisted magnetic recording.

      Let's work it out. A few years ago, TechReport ran an SSD endurance experiment to figure out how much punishment current-gen SSDs could take before failing. Their test setup essentially involved writing random data at maximum speed for 18 months straight. The results indicated that the worst SSD in their bunch, a Intel's 335 Series, wrote about 700 TB before dying, and the best SSD, a Samsung 840 Pro SSD, went on to 2.4 PB.

      Various estimates say you can put between 60-75 hours of HD content on a 500GB drive, so, assuming the largest possible size, that works out to about 8.3 GB/hour. Since you're writing two streams, that's 16.6 GB/hour, or 145 TB per year. For the worst drive in the bunch, that's about 4.8 years of service (right at the upper end of your HDD's service life); for the best drive, it's over 16 years.

      Keep in mind that these tests were all run on 250GB drives. Smaller drives have less flash to work with, and have to write over the same flash cells more often. Therefore, if you bought a 1TB drive, you can expect the lifetime to be easily 4x better (more if you're using a more recent drive, such as the Samsung 850 Pro) - 64 years of DVR recording should be more than sufficient.

      DVR sounds like it would be a more idealized situation for SSD write endurance than database tasks would be. With database writes, you might overwrite the same logical addresses multiple times before you even touch other addresses. The drive firmware has to work with this and try to evenly distribute the writes in flash. With a DVR, you're writing a large sequential pieces of data and consistently deleting only the oldest data, you naturally end up writing the drive from start to finish before looping back around to the start, which was the write pattern they tested in the SSD endurance experiment others have been linking to.

      Most newer SSDs are designed to fail gracefully. When they die, they become a read-only device. All your data is still accessible. Many USB flash drives are designed to fail the same way - if you've ever had a USB flash drive mysteriously become "write-protected", it probably died and set itself to read-only mode.

      That problem was solved in the 2000s with wear-leveling algorithms. Basically, the "sectors" the SSD presents to the computer aren't actual physical locations. They're virtual locations stored in a table. If the SSD senses certain blocks being used too much or other blocks sitting unused, it moves the data around behind the scenes so that writes hit all flash memory cells about equally. It updates the virtual table every time it does this, to fool the computer into thinking the drive is physically the same as it has always been.

      The rated endurance on most consumer SSDs is around 2000-3000 cycles. For a 250 GB SSD, that means you can write 625 terabytes to it before expecting a failure. If you write 100 GB of data to the drive every day, you can expect it to last nearly 20 years. In torture tests, most SSDs have lasted about 2-3x longer than their rating. And no, the first cell failure is not catastrophic. Pretty much all SSDs have a number of reserve cells sitting on the sidelines to take over for cells which fail early.

      If your duty cycle is higher than 100 GB/day, they make special enterprise SSDs rated for 10k-100k writes per cell. The price is correspondingly higher of course, primarily due to using SLC (one bit stored per cell) instead of MLC (2 bits) or TLC (3 bits).

      Limited number of writes were more of a problem in the early days of SSDs when they were like 32 GB in size. In that case, the exact same characteristics as the above 250 GB SSD would yield only 2.2 years of longevity. But the problem has pretty much become a non-factor as capacities have increased.

      2.5" SSD: 8TB (Samsung).

      So again, SSD wins. But now by 2.67:1.

      Hard drives are more dense

      Seems reality disagrees with your assertion.

      and cheaper than solid state drives, in addition to being far cheaper

      You forgot they're also far far cheaper and far far far cheaper. Also cheaper. Oh, and possibly cheaper.
      Of course that's until you look at IOPS/$, then HDDs are suddenly bloody expensive.

  17. Price Parity - Market Factors by ytene · · Score: 2

    The OP rather implies that a supplier offering both convetional HDDs and SSDs of the same capacity would offer their products at prices based upon "cost of manufacture + margin" - i.e. that the retail prices would be a reflection of production costs. Sadly for consumers, this is blatantly not the case. The evidence for this is *everywhere* - for example a BluRay Movie costs no more to make, ship and sell than a DVD [maybe less, the packaging is smaller, lighter and cheaper to ship] and yet BluRay discs cost significantly more. Another classic example is the motor trade, where 2 cars that are identical in every respect except the engine size are priced so that the one with the larger engine costs more. Going back to the storage industry, there may be at least a couple of legitimate reasons for the price differential : first, the vendor is still recouping research and development costs from SSD technologies, whilst HDDs may be investing much less in R&D and therefore cost less. Second, economies of scale mean that a vendor can spread overheads across greater sale volumes and thus one format costs less. Unfortunately, what is most likely to be happening is that vendors are "fixing" market prices and using the principle of "cool new thing" to charge a premium for the latest product, well beyond what legitimate development costs would suggest. In theory many countries have national agencies to stop markets conspiring to fix prices like this. There is legislation against this [it's essentially racketeering and/or market manipulation, after all]. Unfortunately, 99% of the time, large suppliers get away with it. It's only when something goes unexpectedly wrong [look at the LIBOR rate-rigging scandal in the UK] that regulators will act [because it puts them in a position where they have no choice but to act]. Unfortunately, for the rest of us, for most of the time, a price is set on the basis of "the maximum we can get away with", as determined by the vendor.
