  1. Now that helium hard drives have been on the market for a couple of years, would you consider them to be as reliable as existing "conventional" hard drives, more reliable, or less reliable? Will the helium inside eventually leak out?
  2. There was a study presented on Google's datacenter SSDs as of late: https://0b4af6cdc2f0c5998459-c0245c5c937c5dedcca3f1764ecc9b2f.ssl.cf2.rackcdn.com/23105-fast16-papers-schroeder.pdf Conclusions are interesting: SLC not more reliable than MLC 20-63% of SSDs develop a uncorrectable error in the first 4 years and 30-80% develop at least 1 bad block Drives tend to have few or many bad blocks Replacement rates for SSDs is lower, but their rate of errors is higher Anyways, the full study is worth reading. I suppose though that there is no real benefit in keeping SLC.
  3. 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...
  4. hi i really like this forum and i read many review about ssd i would like if storage review is willing to make some reliability test about ssds there are so many tests around , some put the samsung ssd at the top , another the intel someone makes a huge different between MLC SSD and TLC NAND thanks cheers sorry for my poor english
  5. I am getting a new laptop (Lenovo T450s) and plan to upgrade the storage right away. I choose HDD because the cost is still much lower than SSD. Here's my criteria in descending order of importance: 1) reliability 2) capacity 3) performance I am looking at 1TB range. I am going to stick with HGST or WD because of past not-so-good experiences with Seagate. No real failure, but the drives sounded scary. On the reliability front, can anyone comment on HDD speed and temperature? I have been using 5400RPM drives on laptops because I have bad experience with a 7200RPM drive. I am afraid when operating that hot all the time, the drive would fail too soon. The 7200RPM WD Scorpio drive was mounted on Dell Inspiron 600m, the left palm side was unpleasantly hot; sorry, don't have temp reading (it feels well above 40 deg C). In contrast, my 5400RPM HGST drive was running at 37 deg C on a Lenovo T400. Another question--I see the 5400RPM drives tend to have 8MB cache only, while the 7200RPM has 16 or 32MB. Why is this?

  6. Out of curiosity, are Enterprise Hard Drives more reliable than a consumer hard drive? For the money you get, RAID support (possible on consumer drives though as well), TLER, better ability to handle power outages, and a few other areas. I have heard that enterprise drives are built with better magnets and actuators. Pseudo-enterprise drives like the WD Black and the Hitachi Deskstar probably have comparable reliability, although their firmware doesn't have the features. In theory, would an enterprise drive be more reliable as they are built to handle higher workloads? The Backblaze data says no, but the size of their sample is not enough for me to say 100% that they are not. Edit: This is what I have been able to find on the matter: http://download.intel.com/support/motherboards/server/sb/enterprise_class_versus_desktop_class_hard_drives_.pdf
