Robert Look into RAID 1 if you just want to deal with a drive going bad. You can RAID your C: and a single drive failure will be pretty transparent. You snatch out the bad one put in a new one and it will sync up itself. |

Robert It's really really hard to pick hard drives now. There don't seem to be a lot of reviews on Newegg. You can look at the latest BackBlaze results. Some of the drives are too old to find comparable models for sale now. The DM000 for example, I think I have a couple 4TB of those, and for Seagate I was impressed with their "lack of the usual flaky Seagate behavior". You can see in the BackBlaze results, that not all Seagate models are created equal. https://www.backblaze.com/blog/hard-...rates-q3-2017/ Now that both of your computers run Windows 7, there is no longer a need to limit yourself to 2TB drives. If you want to look for, say, drives with good results in the 3TB category, you can look in there too, and when they show up, in Disk Management you can set those to "GPT" instead of "MBR". I won't suggest anything larger, due to the pricing. Selecting a $500 drive, means all your eggs are in one basket in terms of a "failure model", and I'm still not all that comfortable with gigantic hard drives. If I could afford to buy two or three or four of the big drives, then I could have multiple copies, and if one drive died it wouldn't be the end of the world. But $500 drives cause indigestion of the financial kind, so that's just not going to happen. The 4TB may be the sweet spot, but they're also kinda heavy. Anywhere between 2TB and 4TB is probably good - the customer reviews will tell you a lot (i.e. "noisy drive"). If you go large enough, some of the large drives are Helium filled, and no longer have an air breather hole. The only problem with this, is the intended life cycle is 5 years for Helium containment. They should hold their Helium for 5 years, but it's not clear (on average) how they perform over longer lifespans. Both Seagate and WDC have Helium drives and those have slightly lower power consumption. The frictional losses in Helium are lower. And the sealed HDA means there is no possibility of foreign contaminants getting in. (I like this idea a lot, because it means the room humidity can go over 60%, and you don't have to worry about that drive.) If your house flooded for example, you have every right to expect a "washed and dried" Helium drive to continue working. Whereas the air breathing kind (all that you and I own), they're not safe to immerse in water, because the breather hole could admit water into the HDA depending on the barometric pressure that day. The old drives needed to run at atmospheric, and the breather hole ensured the inside and outside of the HDA were at the same pressure. The breather has a hepafilter on it, to remove dust and smoke, and only the tiniest molecules can make it through the filter. While I'd like to, the Newegg comments are too short and full of rubbish, for me to say anything that would add value to your disk selection exercise. When the review column has too few comments, it's called "not statistically significant" and we cannot draw a conclusion. Good luck, Paul |

Robert I am a firm believer in having several external drive backups. Though this has only happened once...I had a PSU take out both internal hard-drives at once. Fortunately it was a a non-critical machine and all was backed up anyway. |

I didn't realize that picking HD's was
difficult now? You would think the opposite? I believe the HD I selected is the one we choose when creating back up drives for the 8500. We first choose the WD but that was too noisy so I made it my External HD. https://www.newegg.com/Product/Produ...82E16822236624 As I remember, you thought the 2TB HD were better than the 3TB HD's, so we went with the 2TB. I still have 794GB of free space on my HD so it's a good choice for me. This is the 780 external HD: https://www.newegg.com/Product/Produ...82E16822178107 So if I buy the Seagate I'll have to buy another case for it as well: https://www.newegg.com/Product/Produ...82E16817707227 Thoughts/Suggestions?

Robert I tried to steer you to 2TB drives, because one of your computers used to have WinXP, and I wanted all your gear to work "no matter what". Now that your WinXP machine is gone from the picture, that constraint is removed. You don't need to buy a bigger drive. I'm mentioning this only as a means to open more opportunities (like if a 3TB drive happened to be on sale or something). ******* The Startech external enclosure doesn't look available any more. There's a Rosewill. RX358. Apparently it lacks rubber feet. I don't know if there are any rubber feet kits with good adhesives. I like something of that nature, to make it harder to knock the unit off a desktop surface. https://www.newegg.com/Product/Produ...82E16817182247 Regarding the Seagate drive, the Reviews have a lot of 1 egg reviews. But since the drive is relatively cheap, perhaps if it lasts three or four years, that's OK. It's hard to find reviews, where the 6TB reviews aren't mixed in with the 2TB reviews, and then you don't know what the overall statistics are telling you. Even Amazon does that, mixes the reviews together like a bad kind of soup. https://www.newegg.com/Product/Produ...82E16822148834 Paul |

I think we matched the computer drives
extremely well and they do work no matter what. I can only go by my own experience with Seagate which all have been good but perhaps it's best to buy sooner than later given that the market is becoming more difficult and hard to find quality products. I would of thought the opposite but such does not seem to be the case. Thanks, Robert |

Thanks, Robert The ST2000DM006 in Canadian dollars here is $80. http://www.canadacomputers.com/produ...em_id=098 711 How do you hit a price point like that on a precision engineered item ? You have to cut corners somewhere. I can't really tell you why those drives break. I read somewhere that the flying height was 3nm, but as to whether it's that low now, there aren't a lot of web pages with detail you can trust. Some of the Seagates seemed to be showing a "wear" pattern, as if there was surface wear. The flying height over the years, has gone from 10,000 nm to 3nm. Sooner or later, that has to have consequences. You can only polish the platter so flat - and reduce the NRRO to a certain level, before the flying height becomes an issue. These companies want to use the same platters in all their products, for mass production reasons. That means the recording density is high. I don't think they actually achieve that. The 15K drives used in servers (very noisy), I think those use a slightly less-dense platter, and the stroke on the arm might be shorter. Some of those drives read at 300MB/sec. But they're not the kind of drive you want in your living accomodation. If you can get this document open, take a look at the disparity between the lower capacity drives and the upper capacity drives. https://media.flixcar.com/f360cdn/We...879-800074.pdf 12TB... 8TB 6TB...1TB 7.0W power 9.3W...7.4W 20dB 29dB...25dB idle -- Same noise level on seek -- That means there are some design differences between the big ones and the small ones. And the big ones could be Helium filled. I think it's possible (and has been done for the last four or five years), to make air breathing 6TB drives. But because they don't tell us the seek time on the drives, it's not possible to tell which is "ripe for pickin". There were the drives with the shingled write pattern, which had simply horrible write performance, and those were "never fit for pickin". They still buy those for cloud storage though. BackBlaze doesn't use them, but I bet there are some other outfits who do. Archive.org couldn't afford to use those, because they need all the speed they can get. For cloud storage though, the upload rate is probably slower than the download rate. Between the running drive, and your new cold spare though, you will have a bit of redundancy. Paul |
