How large SSD should I buy for open source developing?



  • With git, to keep sync with upstream and have my branch with customizations, I have to build from source code, it'll need large hard disk space.
    Currently I need to build ungoogled-chromium. I have no idea what bigger projects I'm going to build in the future.
    Any suggestion for hard disk space?
    BTW, I'm using a notebook, so SSD is preferred.

    Thanks

    @jronald 500GB will be more than enough in most cases.
    Do you know how much space you need when building ungoogle-chromium?

    Some blogs say it needs 100GB at all.



  • @jronald
    How much money have you got? :) If 500GB is enough, and you can afford it, that's what I would buy!



  • 860 EVO 1TB SATA which supports 500MB/sec transfer is $140. Unless you are doing lots of data transfer to and from your computer, or on your computer you can get by with the SATA version. The MSATA are nice, but the non samsung ones I have tested peter out during a large transfer.

    The price is going down in a relatively high speed. Like 50% off a year, now "Hikivision C2000 Pro 1TB PCIe NVME" is about $115, 2TB is double priced. Maybe I should choose the 1TB version, and hope it is not eough, so would have got so many source code that I would like to build (better with modification).

    Thanks

    samsung is of high quarlity.
    But Korea import primary material from Japan, and there is nuclear polution problem in japan, even the food imported from japan got the problem for Korea. When I can be sure about this, I won't build any product made in JP or KR.

    If you have $155 to spend you are richer than I am! (Mind, I have £ sterling, which is getting worthless.) I spent half that on 500GB.

    I hope the chip you get is not nuclear-irradiated. Suggest you don't try eating it. ;-)

    Sorry, typo, the 1TB version sales at $115. $155 is too expensive for me.

    Just watched "Chernobyl" directed by Johan Renck, the nuclear radioation is like invisible bullets that can go thourgh any thing in life.

    nuclear polution problem in japan

    ? Where did you here this? They check for radioactivity at most ports in most countries now. This is part of preventing nuclear proliferation. I highly doubt that it would be in their exports.

    Because of the way the media works in Japan, people don't realize how bad Fukushima really was. In the weeks that followed, the background atmospheric radiation levels went up significantly around the globe. There is a lot of monitoring of atmospheric radiation here because shale rock fracturing is a way they reclaim natural gas from the these rocks, and the shales are slightly radio-active due to uranium decay in them, which out-gasses as radon. Japan produce exports may have some low-level contamination in them based on what metals are present, but could not say how much, or for how long it would be a problem.



  • re ssd for development...I personally discourage ssd for development, but only use them for relatively static operating system images. development does a lot of writing on disks and SSDs have a much shorter expected lifetime than rotational media. I'm currently working on spacecraft flight systems and we MUST use SSD for non-volatile storage. Hardenning the systems against cosmic radiation events is a significant portion of what goes thru my head on a daily basis at work. All you can really do is keep multiple images and CRC/ECC the hell out of everything. Then it is still a non trivial statistical possibility that a stray ray will corrupt data in a non-fixable way.

    Just as a note:
    I been using SSD for heavy c++ compiling for years and also running virtual machines on top of them. Its correct that the first Gen had low write count but newer m.2 disks take terabytes of writes with no issues.

    Not as bad as you make it sound, much worse than it could've been if tepco have handled it better ... in any case most of the radiation release was through leaching into the pacific, not through atmospheric dispersal (you don't have full exposure of the reactor vessel, but a partial meltdown). Now they have no idea what to do with the water they've been pumping through the reactors, so they just store it in tanks ... like that's going to last ...

    In the weeks that followed, the background atmospheric radiation levels went up significantly around the globe.

    Not really. They went up in and around the pacific, not at all much in western asia, the middle east, africa or europe. Only trace amounts of I-131 were detected here in europe way below any significant thresholds. Plus we don't need no stinkin' japanese reactors to irradiate us, we have Russia, which occasionally does that ...



  • @mrjj -- I'll stick with rotational for non-persistent data.
    @kshegunov - it certainly upped the levels here on the east coast of the US. Didn't even want to mention that little ukranian mishap. I would love to have a real sample of Chernobylite though. Trinity site glass just isn't the same. LOL And of course you are right about the Pacific water contamination...

    Eh, maybe. I don't have data, but I'd take a guess on "marginally".

    Didn't even want to mention that little ukranian mishap.

    Actually I was thinking of more recent times when I wrote my comment. Like the friendly Ru-106 we got two years ago ...

    I would love to have a real sample of Chernobylite though. Trinity site glass just isn't the same.

    Nobody makes it as good as in the soviet union, I admit. Although, you can indeed sample it - they do accept tourists now, and east of the civilized world we don't judge people by the color of their money; green is perfectly fine. ;)

    @Kent-Dorfman I never had any issues with SSDs. And one of the reasons why developers should use VCS is to have back-ups - a failing SSD is then a non issue...
