This PCMag article is geared toward the novice computer user, but it's a decent write-up regarding SSDs and HDDs.

Interesting read.  I didn't know that the chips are sometimes a permanent part of the motherboard, but then again, what I don't know about hardware would fill a very large HDD to capacity.

Well this is the case with most apple products that come with ssds and also other small factor machines with ssds. It is basically like how Apple and others solder the ram to the motherboard so that you cannot upgrade the memory and other non-upgradeable parts.

I bought the first linux netbook (Asus EeePC 701) available and it had a ssd soldered to the motherboard as well (it only had a 4gb ssd drive)

Thanks Eric!!

It is interesting to note that RAM memory originally started as soldered in as well.

It became quite restrictive and difficult for users to add memory so the changed to memory slots for ease of use and to make it consumer servicable.

I love the M.2 form factor. It can go into newer motherboards and ultrabooks.

Rather than start  a new thread I thought this would be a neat update on disk changes.

The first SSD I had was on an Acer Aspire Netbook. It was tiny in capacity, had a PATA interface on a paper thin membrane cable. Could likely not have been upgraded. SSDs have come a long way since 2008.

Nice. My latest laptop has a 250 GB PCIe NVMe TLC SSD (Intel). My other laptops just have SATA SSDs in them but I do not think that I could ever go back to using spinning drives for the OS. They are still good for storing media and such but their read/write speeds are entirely to slow for me nowadays.

Same here. My first computer with an SSD in it was the EeeePC 701 and it came with a 4GB SSD. I got mine in 2008.

BTW SSDs have been around since 1991:

Quote

In 1991, SanDisk Corporation (then SunDisk) shipped the Flash based first SSD; a 20 MB SSD in a PCMCIA configuration. It sold OEM for around $1,000 and was used by IBM in a ThinkPad laptop. In 1998 SanDisk introduced SSDs in 2½ and 3½ form factors with PATA interfaces.

I'm still using mechanical drives.

Thanks to a friend. I have a nice SSD, but I'm saving it till I build my next system (or refurbish this one).
