I've been following the news and it's amazing how SSDs are still progressing, a bit slower but similar to Moore's Law. Prices for Samsung SSD 1TB external USB products: - 2015 $600: Samsung T1 http://www.thessdreview.com/our-reviews/samsung-portable-ssd... - 2016 $430: Samsung T3 https://www.storagereview.com/samsung_portable_ssd_t3_review - 2018 $200: Samsung T5 https://www.androidheadlines.com/2018/12/samsung-t5-po…

I'm surprised how quickly prices are falling. I purchased a 500GB EVO 860 only 7 months ago for $139.99. Just checked and it's currently $82.99. For only $8 more than I paid for that 500GB SSD, I could now get a 1 TB SSD. (Naturally, I've barely used that drive, which was slated for secondary storage, and now I wish I had waited.)

I wouldn’t worry about it. If you barely use it, what are the odds you’ll ever fill it up? And if you do fill it up, SSDs will be even cheaper then.

I wouldn't use external SSDs as the price benchmark, since they had a big price premium over an equivalent mSATA SSD back then.

For example, I bought a 1TB samsung mSATA SSD in 2015 for about $320 and it's enclosure for $15. The equivalent SSD today is about $150. So instead of a 3x price decrease in the past 3 years, it's more like a 2x price decrease.

Why is there competition in the SSD market but not in the RAM market?

I'm not sure. The pattern in the DRAM market seems to have been that only the biggest, most successful manufacturers can weather price crashes while still investing enough in R&D to stay on the leading edge. In the NAND flash market, we may simply not have yet seen any oversupply serious enough to do that, for all that we're in the middle of an oversupply-driven price crash.

It is probably the case that it's easier to stay in business with inferior NAND; Samsung beat everyone else to 3D NAND by a few years but Toshiba still made a killing off cheaper, lower quality planar NAND, and Intel/Micron didn't seem to suffer meaningfully from their first-generation 3D NAND being so slow. Now everyone other than SK Hynix has caught up to Samsung and the number of players in the market is actually increasing.

solid state NAS not not laughable, just expansive. RAID 10 a few NVME and you can get decent throughput (and storage size) with existing technology.

I don't know that I'd consider RAID 10 for prosumer. RAID 1, absolutely. RAID 10 seems like needlessly adding more complexity and higher failure rates.

Great point. Complexity is killer in home setups.

Whoa, check out that Samsung NF1 form-factor [0]. Looks like you could pack a ton of small finger-sized SSD drives vertically into a small space.

I'll never forget circa 1996 when I waited 20+ minutes for my Apple Performa 550 to read and load a 30MB file from the scsi disk into memory. All so quickti…

That picture is actually the EDSFF 1U Short form factor, which is the closest competitor to Samsung's NF1 out of the variety of form factors defined by EDSFF. Both allow for about 36 drives in the front of a 1U system.

> RAID 10 a few NVME and you can get decent throughput (and storage size) with existing technology. is there a good reason to do this in a consumer setup? max realistic throughput over gigabit ethernet is only ~120MB/s, which can easily be saturated by sequential reads or writes to/from a single modern spinning-rust drive.

In June 2015, I found the price of a 1 TB SSD was 400 USD, and in December, the price had fallen to 300 USD. In June 2017, I checked the price again and found it was 250 USD. I've put the numbers in my calculator to perform a curve-fitting using the exponential function, and it suggested that "I'll be able to purchase a 1 TB SSD for ~140 USD in 18 months", and I left the number a future note. Now, it turned out the r…

I'm seeing $135 for a Crucial MX500 1TB or WD Blue 1TB (and lower during the recent holiday sales), so we've already hit your target with name-brand drives from major retailers like Amazon and Newegg.

The other amazing thing is size. How much smaller and cooler m2 drives are compared to old 3.5" HDs. If you have integrated graphics, PCs can now be tiny. The big tower cases are really for gamers only.

surprised these are still a thing. I bit the bullet and moved to M.2 storage across pci lanes. It makes my current SSD's feel like spinning disk. https://en.wikipedia.org/wiki/M.2

TFA includes discussions of all SSDs, M.2 formfactor included.

I await the day I can fill my NAS with SSDs. Might save on power usage as well.

SSDs consume more, not less power, to comparable spinning HDs, especially in always-on scenarios. Once started, the amount of power required to keep a platter spinning is miniscule.
