Contentious

This page is very contentious. Could it be made to read less as a defense of HDD and more informative. That'd be great.2602:304:B0D8:6220:C5B4:6BAA:AC2F:43B7 (talk) 19:59, 28 May 2016 (UTC)

Contentious? The article states SSDs are way faster, but way more expensive than HDDs. Can you give examples of what needs improving? --A D Monroe III (talk) 21:02, 15 June 2016 (UTC)

Concur. Please give specific examples of where you think it reads "as a defense of HDD". Jeh (talk) 15:54, 17 June 2016 (UTC)

Susceptibility to magnetic fields

This section is bad. The cited reference includes some talk on the subject, but lacks any expert statements. At best it includes a few people who claim hard drives were damaged by magnets, but I doubt many of the individuals are experts. The magnetic fields required for writing to a modern hard drive are very intense. My understanding is you could put a rare earth magnet directly onto a modern disk platter and the magnetic field of the magnet would fail to damage any data (instead dust and tiny scratches from the contact might well damage the platter). 207.172.210.101 (talk) 01:40, 21 June 2016 (UTC)

Hello! You're right, thank you for pointing it out! The reference was a low-quality one, so I went ahead and made the changes that provided accurate information and much better references. — Dsimic (talk | contribs) 08:42, 21 June 2016 (UTC)

Those are decent, but this these mean that portion of the article needs fixing. Ideally I'd link to sections 4 and the epilogues of the first link (Peter Gutmann paper), which effectively say modern disks (>1GB) are essentially immune to external magnetic fields. The kjmagnetics reads like an amateur experiment (not necessarily bad, but be careful of conclusions!) and says the same thing, their report of mechanical scrapping could well have been due to distorting the case of the drive rather than anything having to do with properties of the magnetic field. "Very old hard drives (less than a gigabyte) may have been at some risk from external magnetic fields, but any drive larger than a gigabyte is essentially immune to external magnetic fields"? 207.172.210.101 (talk) 20:09, 21 June 2016 (UTC)

Hm, I'm not sure that 1 GB is specified in references as a clear capacity-based division between susceptible and resistant drives... Am I missing something? — Dsimic (talk | contribs) 13:52, 24 June 2016 (UTC)

Indeed, 'tis not. The reference was stating post-1990 hard drives were pretty well immune. Bit more recollection, I think 100MB drives were coming out around then, so that may be a better rough guide. The real issue is larger drives have to be less susceptible otherwise the write process would corrupt nearby bits (therefore storage size is a better guide than manufacture date). I don't have any references other than my memory. 207.172.210.101 (talk) 22:23, 25 June 2016 (UTC)

Hard drives and altitude

This portion needs a substantial adjustment. As the cited source notes, many hard drives have an altitude limit of 12000 meters above sea level, but drives designed for high-altitude operation are readily available from manufacturers. This is also becoming less true, helium-filled hard drives are taking over for large capacity hard drives and if they're impervious to helium, high-altitudes are unlikely to be an issue. The mention of the breather hole should be merged with this. 207.172.210.101 (talk) 01:30, 24 June 2016 (UTC)

As always, we'd need references that helium-filled drives can also work properly on high altitudes. — Dsimic (talk | contribs) 13:57, 24 June 2016 (UTC)

SLC, MLC and TLC NAND

Should this not be included in the article? http://www.speedguide.net/faq/slc-mlc-or-tlc-nand-for-solid-state-drives-406 BP OMowe (talk) 14:41, 25 August 2016 (UTC)

TBW

I have seen the term TBW used in SSD specifications and came here to try to find out what it meant. I was disappointed. I eventually discovered that it stood for Terabytes Written in reference to an SSD's expected lifetime. Please can one of the article's main editors add this.

Graphics

The most intuitive dysfunction refers to the moving parts in an HDD. Some people are unclear on that through influence only. As a matter of fact, it IS known that there are no moving parts in an SDD, like the disk found in the HDD, which IS slower than an SSD. For future reference try checking out how an SSD IS like a disc. — Preceding unsigned comment added by 2602:301:7751:160:140f:74da:270a:b1df (talk • contribs) 12:17, 21 August 2017 (UTC)

Alignment in Wikitables

I think the data looks better in the section I edited (30/12/2017), but would look better still if the colon's were aligned instead of simply centering the text.

In MathJax this is `\begin{align} ... &: ... &: ... \end{align}`, with the ampersand aligning the next character, in this case the colons, but is it possible with Wiki markup?
