Re: [gentoo-user] WARNING: Crucial MX300 drives SUUUUUCK!!!!
I had a crucial SSD drive too and it failed in the warranty but as I didn't have the receipt they refused to honor it and said I was out of warranty as based on the date they sold it to the store not the day the store sold it to me. Apparently failures on my model were a very common thing due to a manufacturing defect. Thank god for backups. Bunch of jerks, don't buy from them.

I finally got tired and replaced my old laptop with a ThinkPad P70, and boy is it so much faster than anything else I own. Compile times are crazy fast on this new laptop of mine, but it came equipped with an i7 with 8 threads and 16GB of RAM, which I'm sure helps A LOT.

I only used fstrim in single user mode before I made my weekly backup. I can imagine that it will cause a I/O bottleneck while it runs. P.S.: I wrote by mistake, that I used fstrim to reserve free space on the drives. Actually I used hdparm for that. -- Regards wabe

It really helps when you always left some free space on the drives. I used fstrim to reserve additional 20% free space on my SSD drives. I said additional because manufacturers always(?) reserve some percentage free space for overprovisioning. This not only expands the lifetime of SSDs but also helps to preserve write performance. > > I can't say they're more or less reliable than spinning disks, > > though they do have the benefit of no moving parts to wear out over > > time (thermal cycles can still cause a physical failure on them, > > though). > > Have you noticed a difference between mounting partitions on them > with the discard option, Vs running fstrim on a cron job? I noticed a big performance impact with my old Corsair 60GB SSD (Force3 IIRC) when I used the discard option in fstab. So I decided to use the fstrim command instead, before I did my weekly backups. The fstrim command always needed about 10 minutes or so to complete its job. About 1 year ago I replaced the Corsair with a Samsung SSD 850 PRO. With this device I did not notice a performance impact when the discard option is enabled and so I decided to use it. Btw: On the Samsung SSDs the fstrim command only needs a second or so to do its job. I never used a benchmark program to check if there is really no difference. But at least I don't notice any in my every day use. My old Corsair SSD (bought it in 2011) is still in use as swap space device in my Win7 machine (together with a SSD 850 PRO as system device). Before that, I used it as system disk on my gentoo machine. I also used it for my users mail and thumbnail directories and also for /log, /tmp, /var and the whole portage tree. Before I upgraded my gentoo machine to 16GB RAM I also used the SSD for portages temporary files. So it was really in heavy use. And is still running without problems. Before I installed the Corsair SSD into my Win machine, I used fstrim to increase the reserved space to 50%. I hope that it will run for at least another 6 years. ;-) -- Regards wabe pgp_2HmSIJKiB.pgp Description: Digitale Signatur von OpenPGP

Gambling on that chance by leaving a given disk as a single point of failure is still a bad idea, spinning disk or not. The point that you went from single-disk SSD back to raid10 makes me question why, if your uptime requirements (even if only for your own desires on a personal machine) justify raid10, you weren't on at least raid1 with the SSD setup. As for performance degredation on SSDs, that I've definitely seen on pretty much every brand, though I've had good luck doing clean reloads on samsungs once or twice to get speeds back up some (somehow, even trim doesn't seem to keep things at their best). I can't say they're more or less reliable than spinning disks, though they do have the benefit of no moving parts to wear out over time (thermal cycles can still cause a physical failure on them, though). -- Poison [BLX] Joshua M.

I know everyone's saying these things are reliable but out of four SSDs I own, I've had to replace three, some more than once. I just don't use them for anything I want to stay working. Right now I keep them in my mythtv frontends as I can restore the OS easily. One one of them the company involved (Kingston) even sent me a newer drive/model as it was replaced more than once. I know they're fast. But what's the point of going 500 MPH and crashing into a mountain with no chance of repair/recovery. I went back to a (relatively) slower rust raid10, and it's been reliable for the last four years. At least with a hard drive failure, you stand /some/ chance at recovery, not zero. The one SSD that hasn't had to have been replaced under warranty is in my laptop which I generally use maybe a dozen times a year. I fully expect it to die one of these times when I boot the laptop (it's one of the old models.) My experiences are with Samsung, Kingston, Intel, Crucial and AData SSDs. The last one I bought because these things I view as throwaway devices (the warranty expired on the original Crucial) and don't want to spend big money on them. I have noticed the AData SSD's performance is not as fast now as it was new (maybe 1.5 years ago?) So it'll probably pack it in soon too. Dan

A single drive failure is an anecdote, not an indicator of a systemic failure of the entire production line (let alone brand), especially if it lasted 20 days past install... which is well outside anything a quick, every Nth drive, QA test on the production line is going to pick up unless they happened to grab that single, specific, drive. As 20 days is also well inside the warranty they give on that drive, a replacement's not likely to be difficult to get from the manufacturer (and if you purchased it within the past 30 days, from typical vendors if you prefer). I don't *think* I have any of the MX series, but I have had good luck with the one BX200 I have in my work desktop, and I've heard good things on the handfull of BX series drives my boss's deployed in various desktops and laptops. I haven't done any deliberate performance testing on them, but I can attest to much better speeds out of my BX200 than the spinning 500GB sitting under it in the same machine. As for the failure *mode* of your drive, simply, completely, dead... that's been my experience on every failed SSD I've seen, be it a samsung 850 pro, an early crucial drive, corsair, and even intels. I suspect either the controller itself is the point of failure on them, or it's simply incapable of working around a failure of some other component. Lastly, while drive failures do, very much, suck... they happen. That's why backups are essential, and also exactly why raid levels outside of raid0 exist (one is not a replacement for the other, 'course). -- Poison [BLX] Joshua M. Murphy

LOL! I did laugh reading this, thanks! I have no experience with SSDs badged by Crucial. I have been using a 240GB OCZ-ARC100 on a daily basis for more than two years now, and it is still working. -- Regards, Mick signature.asc Description: This is a digitally signed message part.

I have 3 of these class of device (if I recall) 3 Crucial SSDs where I have only had issues with the one install of the device, and I'm not really sure *why* that might be causing problems, but I suspect that a good part of why it "just won't work" is because of the UEFI system on that machine, or something installed "inside" the UEFI which makes it confuse the heck out of the machine. I have intended to boot into and install Gentoo on it, to see if doing so is "doable" or if I should strip the machine, and hope I can get some useful components out of it. Perhaps the optical drive would work well, on this machine, though I don't really have a reason to switch this machine's optical drive out right now. My suggestion is the drive *should* be under warranty, so get a replacement that way, and hit up some other manufacturer if you can afford to. I have heard people say that they have had drives running for 10 years, but I may have misheard.

[gentoo-user] WARNING: Crucial MX300 drives SUUUUUCK!!!!
Dear god, I think I have come in contact with one of the suckiest things in the universe! I mean first there are supermassive black holes... OK... Then there's Crucial MX300 SSDs, and in a distant third there's Justin Beiber. I mean the absolute suckyness of MX300 SSDs defy human comprehension. I mean you could connect one of these: http://www.zmescience.com/science/biggest-most-poweful-engine-world/ to a suction pump and it couldn't possibly suck one quintillionth as much as this SSD... I mean if the power goes out, and you want to do some vacuuming, just put your MX300 behind the bag in your vacuum and it'll work better than normal. Seriously, what could possibly suck harder than a SSD which dies stone cold dead after only 20 days?!?!?! Thank god I had done nothing worse than store my rusty old Velociraptor on a shelf, and by good fortune it only took about two days to get it updated... I really hadn't intended to ever use it again. =\ I'm not sure what lesson I should take away from this except that Crucial does not have any business selling SSDs. =\ I'm not sure where to go from here. My 'raptor is very close to exceeding it's reliable lifespan, by some standards it already has... But now the QC of these SSDs has been shown to be outrageously bad. =( So does anyone have any evidence of a current generation SSD lasting more than 20 days? -- Strange Game.
