Always love reading HDD reliability stats from Backblaze -- but this demonstrates one of the reasons why post dating is so important, especially when the information in the post is time-sensitive. Nowhere on the page does it say that the post date is today, unless you click the "latest posts" tab by the author below. I had originally though it was a repost of the many older articles from Backblaze until seeing a refe…

Yev from Backblaze here -> it's an internal debate as to whether we should put dates on everything. It used to be that they were part of the URL (because of the way our blog was designed) but that is no longer the case. We decided to leave them off for a while to see if that made posts more "evergreen", but we definitely see where it can lead to some confusion. We'll keep chatting about it internally, there's likely…

hey Yev, how about something secure like TLS 1.2 on the blog? RC4 and 3DES are great if you are playing hackme's at defcon to let people break your 'secure' connections on the fly using laptop GPUs, but not on supposedly Secure Cloud Storage company blog.

Oof. I've got a NAS with 4 3TB Seagate Barracudas, same model number as the drives with the 46% failure rate. One's already failed, and I replaced it with the same model drive. Anyone have a recommendation for how to replace all the drives with more reliable models without wrecking the RAID? Downtime is okay, but I don't have spare space for the contents to make a giant backup. It's currently set up as a "Synology Hy…

HGST drives are slightly larger than Seagate of the same advertised capacity. Replacing Seagate drives with HGST ones is therefore easy, while it's often impossible the other way around (fortunately :)

I can't load this site because blackblaze only supports 2 TLS ciphers. TLS_RSA_WITH_RC4_128_SHA, TLS_RSA_WITH_3DES_EDE_CBC_SHA

Those are old ciphers, so they should be easy to enable in your browser.

Without a backup, you need a temporary, identical NAS device with the 4 new disks. Then do a file-level copy. Then put the 4 new disks in the old NAS and import the array. Do you know of a store with a very lenient returns policy?

An online capacity expansion (replacing one at a time) will mean a very long time in a degraded state, possible multiple disk failures, increased chances of data loss (power goes off, etc)

The winner of this post, HGST (formerly Hitachi Global Storage Technologies) is a wholly owned subsidiary of Western Digital. Their NAS are well rated on Amazon & Newegg. Personally, I'm more concerned about the lifetime of laptop HDD (500GB range). Wonder what's the time frame around which I should swap it out (& what brand)

Given that you can get 512GB M2 SSDs now, I'd say go for that if you're worried about reliability. From what I've read, SSDs are more reliable unless you're trying very hard to wear out their endurance (on the order of 2PB according to http://techreport.com/review/27436/the-ssd-endurance-experim... )

SSDs mainly fail by FTL corruption bugs, not flash wear.

BREAKING NEWS -> There are now dates on all of the individual blog posts. The landing page is "date-free" but is in chronological order, if you open a post, the date will be below the title...AS NATURE INTENDED!

That's amazing - I'm reading the post right now (as in, 11:28 AM pacific)- and I switched back to the tab, and it doesn't show the date. But I opened it less than 10 minutes ago. They couldn't have changed it that real time could they. Hit Refresh. Lo and behold - there is the date. Now that's an agile organization. Thanks very much - I really appreciate the date on these posts as well.

Our pleasure :)

Evergreen, now there's a euphemism. :-) I appreciate, in the end you have to do what gets you the most views, however, from my perspective missing out the date means you prefer to waste my time as I have to scan the article until I get a feel for how old it is. I would read anything written within 6 months and would consider up to 12 months if the information was high quality. It's not like we're overburdened with qu…

Note to the point, it shows that Backblaze cares more about content marketing SEO than HDD reliability.

Yev from Backblaze here -> We've actually done a lot of experimenting and content/SEO marketing has helped us grow and expand quite a bit over the last year. As for the HDD reliability...our software works around HDD failures, so they don't affect is too much, but we do like reporting what we've seen in our environment. Hopefully other companies will do it too.
