Exciting times indeed, just type "ssd" in your favorite search box. I'm about to upgrade to a 512GB SSD that costs half what an SSD half its size used to cost 5 years ago! Starting this year, I'm considering getting a low-end 120GB for $25 every year on January 1st to use as a write-once backup for all my work.

As I understand, SSD would be an especially poor choice for this - an SSD left unpowered for an extended period will begin to experience data durability issues. The firmware of a powered SSD will mitigate this issue by engaging in periodic refresh activity. This is a classic use case for tape. LTO drives support reading up to 2 generations earlier, i.e. an LTO-7 drive can read an LTO-6 tape. By not using the latest s…

What about a Industrial SLC SD Card ? Like that:

Is it safe for backup or same problem?

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…

Meanwhile Apple is charging $1,200 for a 1 TB MacBook upgrade. Hoping this year we see a significant jump in consumer availability of these drives. I’ve been using a 512gb laptop since 2010 at least. Would be nice to start seeing multi-terrabyte drives in devices besides after market or external drives.

What would consumer availability have to do with the $1000 apple tax?

1tb SSD are already significantly cheaper than what they are charging. They don't seem to base their pricing on cogs.

This is the new Apple RAM surcharge — remember back when Apple let you swap out DIMMs, they would charge 3-5x market rate betting you wouldn’t. Now they’re doing it on SSDs but you can’t get away :) If you follow the r/buildapcsales it’s pretty eats to get a 1TB 2.5” SSD from a top manufacturer for under $120, and M.2 for $20-30 more. I just got a Crucial MX500 1TB for $114 all in.

My understanding is that SLC is seen as safer, and lower densities are also seen as safer. Beyond that I don't know for sure.

I imagine that even an "industrial" grade flash card is still engineered with the assumption that it will be turned on for a while every now and then.

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

I had planned on doing this but even with gigabit wifi, and half gigabit transfer speeds for the SSD, NAS encryption algorithms seems to cap the transmission speeds to around 100 megabytes per second

I have all the parts I just haven't formatted my SSDs to go into the NAS yet and I'm not sure if I will

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.)

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…

It's pretty much there —- the Samsung EVO 860 1 TB is $147 at Amazon.

To be fair, the $200 1TB SSD linked above is just a standard 2.5" SSD where the Apple SSDs are M.2 with triple the I/O speeds. These Apple(s) can't be compared to the list of oranges above.

I think it's unlikely that manufacturers will want to turn their consumer SSD devices into a dumb flash storage and move their FTL into the open (like a API layer inside the Linux kernel). It's where their added value lies.

I think we're talking about the opposite where the SSD could take over some functionality from the OS.

Which OS? There are many, which is why they won't.

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.

Even gamers don't need towers, games don't benefit much from anything > 4 cores and the only limiting factor so all you really need is a mini-itx motherboard, 8-16GB of ram, and a beefy GPU attached. There are plenty of console sized cases out there you can build in that can fit a 2080 or Vega card.

Big cases are really for tons of mechanical drive capacity, > 8 core CPUs, addin cards like network switches, or a ton of GPUs in a compute cluster.

No it is not, I linked to the external Thunderbolt SSD (last one) so there are many more pieces involved in the Samsung SSD. But it's true that the Apple one is a lot faster since it's internal.
