  1. Thanks for all of your help, again. I realized the drive I was considering from Amazon was a bare drive, and the same drive was available at a local store in a retail box for not *too much* more, so I still went with that. The brick & mortar store also had bare drives that to my horror were just stacked in a plastic crate only in their antistatic bags, so I made a note to try to get retail drives only from now on -- I guess this could have as much or more to do with any damage than mail order vs B&M. But this does give more flexibility than I thought if realistically most drives arrive undamaged. I'll look into testing the drive. By any chance is there an obvious program that you guys use to use to test HDD's, or are there many good ones? I just now learned of SMART and have Piriform Speccy that has it, and have HGST's program that maybe has more than SMART. I know of CrystalDiskInfo (I know they benchmark flash memory) and SpinRite, and know there are others (am only just now getting into it). Thanks again for your help.
  2. Is it true that it's better to get HDD's from brick & mortar stores rather than from mail order like Amazon, Newegg because of the additional bumps the HDD will accrue during shipping (UPS), being handed off from step to step, going through conveyer belts, being dropped in bins, etc? This is exacerbated by Amazon and Newegg not packing them well (sometimes just one air pillow, or nothing). I think the idea is that when they're being shipped to brick & mortar stores, they're going to be part of a pallet so won't get bumped as much. Internal HDD's I've seen seem to come in cardboard boxes, with styrofoam inside, but external HDD's seem to come in plastic blister packs/clamshell packs, not so much padding. I know the heads are parked so they're not as vulnerable, and manufacturers release data on shock tolerance. On the other hand, I read opinions that there can be cumulative damage on the whole to the mechanism, so by the time you receive it the lifespan or reliability might be compromised. What do you guys usually do? Thanks for your help...
  3. Thanks. Yeah, I was sort of leaning that way, and you definitely affirmed it as the most sensible way. As you said, the sample size is small, especially given the slight differences, and nothing beats having a backup. I'll probably get a USB external HDD of same size to do complete backups. Thanks for your help and thanks for reading.
  4. Looking for a laptop drive. Comparing WD Black 2.5" 750GB to HGST Travelstar 2.5" 7K1000 7200RPM 1TB. Speed isn't as important to me as reliability (I've lost 2 HDD's in the last year). I understand the WD Black might be slightly faster than other 7200RPM drives and that this was its original claim to fame. I also read that it's more reliable too, though, but haven't been able to substantiate that really. I understand the WD Black isn't enterprise (and there aren't any 2.5" enterprise drives?). I read -- though don't know if it's true, or if it's only true for 3.5" and not 2.5" -- that the WD Black chassis is heavier, though that might only figure in certain uses. Also I understand the WD Black warranty is longer at 5 yrs, but this could just be WD's willingness to charge more for the warranty in the overall price and not necessarily greater reliability. I read Backblaze's reports that other than a few Seagate models, HDD reliability doesn't vary greatly (and that Backblaze doesn't really use WD, so doesn't know much about WD). I found a comment from WD customer support to someone with a similar question as mine: "Kindly take note as all drives are designed around a 5 year life span. Our drives have less then a 1% annualized failure rate and cost difference is usually because of warranty length and features. (speed, cache, RAID, ect.)" Also, from WD's site, WD Black and Blue are both rated for 600,000 load/unload cycles, while WD Green is rated for 300,000 load/unload cycles, and HGST says their 7K1000 is rated for 600,000 load/unload cycles... for whatever it's worth. I'm sure this is only one aspect of reliability. Does anyone have any thoughts or advice on this? Is the WD Black more reliable, or is it that all consumer HDD's are about the same? If they're about the same I'll probably go with the HGST 7K1000 (slightly less noise, more capacity). Many thanks..
