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. [0] https://images.anandtech.com/doci/13752/IMGP2727_575px.jpg This is one way in which it's a cool time to be alive. 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 must get really hot, I wonder how well it cools?

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.

I'd expect USB drives to be more durable. Would be nice to know.

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.

Having to sort files among multiple volumes is also complexity and can lead to mistakes.

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 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.

mSATA SSD's are so rare these days

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.

I don't think that's true

True, but Samsung is still making them. A 1TB mSATA 860 EVO is currently only $3 more than the M.2 SATA version of the same, so it's still a reasonable comparison against drives from several years ago. (However, both mSATA and M.2 SATA versions of the 860 EVO are more expensive than the 2.5" version that faces far more competition.)

There's no backplane to get in the way of airflow, so it is quite a bit easier to cool than a typical hot-swap bay full of 2.5" drives: https://images.anandtech.com/doci/13218/IMGP2722.jpg

The new connectors between the drives and the mid-plane board are probably the most important innovation these new form factors bring to the table, though something similar could also be done for existing SAS/U.2 connectors.

Don't write optical media at the maximum possible speed, reasonably protect it from light, and it will last much longer. I always did that and haven't lost a disk yet. I'd need to recheck a few really old ones, though...

And don’t stack them one on top of another. I recall reading that added weight on the disks (common when they’re stacked horizontally) can result in data loss because of the dye changing structurally. Store then standing sideways, and as much as possible, closer to a 90° vertical angle.
