This article confuses the M.2 form factor (family of form factors) with the NVMe protocol

There are statements regarding, e.g., the speed of M.2 drives, which are only true when the M.2 drive uses the NVMe protocol, while overlooking the fact that other M.2 drives use the SATA protocol. (I believe the term "protocol" is more appropriate than "interface" here, and form factor is something else again.)

I'm having a first pass at correcting the issue, but someone else who's more informed on the subject should improve the article further. — Preceding unsigned comment added by W.F.Galway (talk • contribs) 15:51, 22 September 2018 (UTC) খানকির পোলা — Preceding unsigned comment added by 182.160.127.102 (talk) 09:30, 27 September 2020 (UTC)

Weasel Words?

After an IP tagged the article for Weasel Words I scanned the article for same and did not find any such enumerated words that were not appropriate so I removed the tag. Tom94022 (talk) 17:45, 10 April 2019 (UTC)

Psion MC 400?

https://aliennerd.files.wordpress.com/2012/03/20120327-_1020719.jpg

https://jbmorley.co.uk/posts/2017-07-04-psion-mc-400/ says "The MC 400 even sported Psion’s own ‘SSD’ external media, which could be found in both a write-once flash version, and the a expensive read-write battery-backed form."

"write-once" and "battery-backed" appear to contradict our Flash memory article. I can find plenty of sources where Psion called it a SSD, but it might be that "flash" is a claim added later by non-technical people describing the Psion. Does anyone have a source where Psion called it flash? --Guy Macon (talk) 15:16, 27 September 2019 (UTC)

Regardless of what it was called, it doesn't meet the definition of an SSD in terms of form factor and interface. Maybe it is appropriate for the Early SSD Section but not as added. I'm going to revert the addition until this discussion is resolved. Tom94022 (talk) 22:44, 27 September 2019 (UTC)

Computer Magazine, December 1990 p. 93-4, states "The MC uses solid-state disks (SSDs), which are really just memory but which emulate disks. The MC accepts up to four SSDs at once, available in several styles and sizes: Flash EPROM and RAM (each up to 512K) and ROM (2MB). Psion offers an SSD drive for a PC." This sounds like a RAM/WORM/ROM disk and not an HDD interface so it probably doesn't belong in the article such devices are already mentioned and were much earlier. The fact that the Psion used the term SSD is IMO not worth a footnote. Tom94022 (talk) 06:31, 28 September 2019 (UTC)

I agree with Tom94022. Good call. --Guy Macon (talk) 14:18, 28 September 2019 (UTC)

Linux systemd versus weekly.cron

In the "Linux" section, mention of systemd fstrim.timer should be added -- in most Linux distributions it has replaced invocation by weekly.cron . Also, the recommendation (per 'man fstrim') to run 'fstrim' once a week should be added. (I leave this to an fstrim guru.) BMJ-pdx (talk) 00:29, 18 June 2020 (UTC)

No a constructive use of language.

The sentence "Now a days external SSD drives are also available in the market to make sure it's availability for all PC/Laptop users." is not a constructive use of English as a language... Nowadays, its, dubious reference unclear what the message of this statement should be, if any. — Preceding unsigned comment added by 37.211.78.249 (talk) 20:45, 14 December 2020 (UTC)

This article desperately needs to be updated

Title.

From what I've seen, here are a few things that have changed since 2017/18:

Average SSD price is usually about 25c per gigabyte or even less on cheaper models, like QLC or SATA drives
120GB SSDs are practically impossible to find today. The minimum size that can be easily found today is 256GB, which itself has become increasingly rare
SSDs can commonly be found up to 8TB, or in rare cases 16TB
No modern consumer SSD has a data throughput of 200MB/s, where'd that come from? Typically, the minimum is 600MB/s (for SATA drives). As for the maximum, that's hard to say. My drive reaches 6-10GB/s write speeds often, and read speeds are nearly double that, sometimes hitting 16GB/s which is the maximum throughput for the modern NVMe standard if I'm not mistaken. On average, however, it seems that the max write speed is 4-6GB/s. Unsure about read speeds
Fragmentation is a problem on basically every single modern FS. However, NTFS is just an extreme case. All filesystems fragment, but usually aren't as bad as NTFS

Well there it is. This is, of course, only my personal findings, but I can try and find actual sources for these if necessary. Some stuff could also have better clarification and wording but that's unrelated I guess. Swirl0 (talk) 20:03, 15 December 2020 (UTC)

I've seen some drives cost less than 10 cents per gigabyte. Still, the thing about 30 cents per gigabyte on average is definitely inaccurate. Swirl0 (talk) 19:32, 25 December 2020 (UTC)

I think the Linux section might be outdated as well, since on my modern installation the default scheduler is one optimized for SSD usage. 46.142.185.73 (talk) 16:04, 30 October 2021 (UTC)

I absolutely agree that this article needs to be updated. From my point of view, for example, the missing developments since 2017/18 and the years before in the field of SSDs can be added for example as follows: Actual replacement of HDDs by SSDs started maybe in 2010, when at the same time HDD unit shipments peaked at about 650m units. By 2014 roughly 40m SSDs where sold compared to about 550m HDDs. Over the next years, serious volume replacement took place and by 2020/2021 there were more SSD units sold than HDDs.

/r/ requesting to expose samsung 850 / 860 / 870 evo 2.5" drives' technical specs.

I cannot find microcontroller, cache memory and NAND litography information from the internet.
