OMG, a 7.6 TB 2.5" SSD...does this really exist?

Fri Apr 19, 2019 6:08 pm

It appears to exist and not be a late April Fool's joke.

If so, that's great news for the future.

30 TB for just a scosh above $12,000. That's BA. :P

Don't forget the 100TB ExaDrive!

https://nimbusdata.com/products/exadriv ... able-ssds/

It's 3.5" instead of 2.5" but still pretty intriguing. And I'm sure it's got a big fat price tag to match its big fat form factor.

SSD density is typically limited by how much money you have, not really any crazy engineering or packaging. The bigger drives (30TB+) all have 32 GB+ of DRAM on them, with enough supercapacitors to dump that cache to stable storage.

Yup. Think about the storage density of a 256GB micro-SD card for a minute. How many of those could you pack into a 2.5" SSD form factor? Gang 'em up in a RAID array to get more parallelism to boost throughput, and add a margin of over-provisioning to get the write endurance up to something reasonable, and you've still got a heck of a lot of storage capacity in a 2.5" SSD form factor. Of course this is somewhat of an over-simplification; but storage density of flash memory is not the issue. It's all about cost.

Which really comes down to lots of DRAM caching, over-provisioning, and running the drives hot for writes.

When I was playing with an IO Drive Octal back in the day (I'm still amazed I was allowed to carry/install/beat the snot out of it - it was pretty close to 6 figures at the time) I think I managed to write the best bits ever on flash for cold/offline storage - I got the thing to thermal throttle the flash was so hot. Those were good days. :lol:

From https://www.cnet.com/how-to/how-ssds-so ... -lifespan/ :

The Page File's size tends to change dynamically, resulting in frequent writing to the drive, which, again, is not good for an SSD. So if you use a computer with 8GB of RAM or more, and you generally don't run lots of concurrent programs, it might be a good idea to turn off Page File completely. However, the best practice is to set it at a fixed size recommended by the system. Or if you're on a desktop with an SSD as its primary drive and a secondary hard drive, it's best to move the Page File to the hard drive and disable it on the SSD


That's terrible advice. Defeats the whole purpose of having an SSD in the first place. Wonder how many poor souls are doing that and thinking to themselves, oh my SSD gonna last a longgggg time coz I'm so smart. Sigh. Personally, I would just add more RAM and disable the pagefile completely.

Yeah, I agree it's kind of dodgy. Not sure I'd go all the way to calling it "terrible" though. For typical desktop workloads, it is almost never a good idea to turn off the pagefile. If you're paging a lot, add more RAM; if you're not paging a lot, using the SSD for your pagefile shouldn't cause a significant increase in flash wear. But if you're not paging a lot, putting the pagefile on the HDD isn't going to hurt performance a whole lot either. So it's more of a "meh", really.

I don't know about that. My work system has an SSD and 16GB RAM and the pagefile is disabled since installing the SSD. Have yet to see any adverse effects.

People who run desktop Windows with the pagefile disabled fall into two categories: Those who are having problems because it is disabled, and those for whom it hasn't caused problems yet. :wink:

Agreed 100%. Just set it to a fixed size (approximately equal to RAM, or 16 GB, whichever comes first) and leave it alone. Page file writes are absurdly optimized for streaming to/from HDDs, they aren't going to wear our your SSD.

I'll also call "BS" on advice to twiddle around with pagefile settings, and especially to those who delete it. On one hand, you hear people say "it doesn't cause problems". Then the truth comes out some weeks or months later. They get blue screens now and again, or other wacky crap is happening. But no, deleting their page file doesn't cause any problems. Can you spell "denial"?

Personally, I don't understand why Microsoft hasn't yet disabled the ability to have a 0 sized virtual memory option.

The only thing I used to do was move it to another partition and never defrag that partition, just to avoid having it be a big block of un-defraggable space on my OS partition. But that was the "olden days". We stopped delivering most mail by horseback and we stopped watching black and white television for a reason. With SSDs now, that doesn't even matter anymore. People, stop tweaking your Windows 10 systems, that's just a waste of time!

Not yet. Not for about forty years.

One possible future... from your point of view.

I don't like letting it auto-size. That definitely burned up a bit more cycles as it grows and shrinks since the pagefile is usually written out with minimal fragments.

Maybe that's just old me talking. :)

For 99% of people, the default is the right option. Very little downside and avoids the potential risk of misconfiguring.

I have a Samsung 840 Evo that I stopped using because... well, it's a Samsung 840 Evo. I'm toying with the idea of dusting it off, reformatting it, and using it exclusively for page file and temp folders.

Thoughts? Good use of resources or just asking for trouble?

I think for something like that it should be fine. Before the final firmware update, the issue was dog-slow access to data which was more than a few weeks old. With the patched firmware, the drive should behave itself as long as it isn't left powered off for extended periods. I still have a couple of them that I use for scratch space and VM hosting in my primary desktop, and haven't had any issues.

Make sure you have the latest EXT0DB6Q firmware installed, the first iteration of the fix still had issues.

If you mostly do gaming on your system, that shouldn't be an issue. Don't trust it with your critical data or work, just to be on the safe side.

Microcenter is selling Inland 120GB SSDs for $16.99, and 240GB models for $26.99, making the 840/840EVO essentially worthless. Not sure it's worth corrupting anything at those prices.

If the HD is used for anything it'd hurt perf on the HD.

SSDs are great for pagefiles. I'm with the "leave it the hell alone" crowd unless your OS drive is an HD.

Microcenter also has an Amazon storefront which sells them. And there are other similar priced SSDs these days. They're not the highest performing models, mind you, but if you're comparing to an 840EVO....

Certain applications and software trip the Commit Size even if you are just using 8GB of your 16GB of RAM. Windows 10 makes far more use of compression and caching.


Seems disabling the pagefile is a very REAL problem with Windows 10. I'm on Windows 7 so that explains it.

Yeah. There's probably a decent overlap between the people running with the pagefile disabled and the people still running Windows 7 with 8 months to go :wink:

Why are you so worried about the SSD's endurance, is it not being backed up?

Edit: sorry if this sounds abrasive, it's not meant to be, but I just don't understand why the extreme concern over the possible wear and tear on an SSD, to the point where you're advocating turning off the pagefile. Is it a particularly small one? Or old? Even the e.g. M500 was spec'd for 72 TBW (= 39 GB every day for 5Y). Do you plan to keep it for 20Y and so worry that you might be over the 12.3 GB per day average which that implies (if you page, whereas you wouldn't if you didn't)?

Edit 2: even if you paid e.g. $160 for a Crucial V4 256 GB in 2012, you're way past the spec of 3Y expected life (warranty implied) so you've got way more out of it that the you could reasonably have expected, so what's the point in trying to not hit the 36 TBW spec for the endurance spec? Especially when you can get a replacement BX500 240 GB for $29 or less. ??emoji??
