Love & Joy

Posted by meronpan on April 7, 2009

While I’m working on my Exelica Nendoroid review, here’s a public service annoucement for Miku fans:

Watch this video now.  If you don’t have a nico nico account, I’ve made a post at dannychoo.com that has the video embedded.  If for whatever reason neither of those options appeals to you, you’ll have to sign up @ nicovideo or wait ’til someone uploads it to youtube ^^;

mmd

Chibi miku is too cute for words ^^  Many comments flying across the screen say, “I died” or, “Death by cuteness/moe,” etc.  I fall in that category ^^;

In computer news, I think I’m finally on track to having a robust backup system.

If you do name your drives, what are their names? ^_^

Alrighty, review coming in the next few hours…

以上!

    Wow chibi Miku with one big ponytail o_o , no wonder so many people died there ^^;

    I only have two external drives (one was actually recovered from a dead laptop x_x), and while I have not named any of them, my big one happens to be called 新增磁碟區 (“Newly added disk area”?) as it was bought and partitioned in a local computer store. ^^;

    Glad you repaired your system :)

    I got back my repaired hard drive today , so that’s all good too :)

    i did name once my hard drives but they all died so i didn’t do it again :p

    I demand you rename your Drive C! Tsukiumi is my wife!

    Love the video, and omg your hard drives *drool*

      unfortunately kiriha was just consumed by tsuyuri ^^;; i converted the two drives to a RAID 1 array yesterday. err for those less RAID inclined, RAID 1 is a special setup where you take an even number of hard disks and half of them are automatically used to backup the other half. i.e. now whenever i write something to tsuyuri it will automatically be copied to (the invisible) kiriha ^^ theoretically if either drive ever dies, i just pop in another drive of the same size and it will automatically be restored from the backup.

  5. Hey Meronpan, why are you so insistent on using a raid? A RAID is nothing but a terrible idea with the way drive storage has gone. RAIDs almost fail in a cascading manner, RAIDs are irrecoverable if you lose a single drive while using striping. If you’re using mirroring, the drives almost fail simultaneously.

    You’re far better off just using the drives as seperate drives.

      mmm true, RAID might not be worth the trouble…. (I’m using raid 5 in a 2tb array and raid 1 in a 1.5 tb array). However, regarding a plain 1, i’m not sure i’ve ever heard of the drives failing simultaneously most of the time. is that from experience or…?

      5 combines the performance gains of striping with the security of parity, so though i increase the risk of raid failure with multiple drives it’s offset by some speed benefits and the ability to recover with the parity data…. i guess again, are you saying that multiple drives fail usually?

      i suppose with the increasing drive size and the chance of being unable to rebuild an array due to the simple probability of having a read failure being so high (i keep seeing 12tb as the size where raid 5 is basically broken)… i might switch things up to a raid 10… the primary reason for this array would be speed, but not wanting the risk of a 0 alone.

      in the end, i guess my main reason for using raid arrays is to not lose any data in the event of a drive failure. manual backups always have a temporal component involved so i’m likely to lose a week or more of data.

      • Raid 1 drives usually fail nearly simultaneously most of the time because you are usually using identical drives or drives of similar age, they are also subject to identical conditions during an operation in a raid 1. Given that the drives have similar mean fail time(and most drives do, unless you’re using enterprise edition drives like me :P), you may see your two drives fail nearly simultaneously.

        Also when running mirroring, write failures and read failures that lead up to a drive failure also unfortunately get reflected in your mirrored drive as well. It’s not as wonderful a back up as you would think it is. Also, again because of the identical conditions it is entirely plausible that your backup and main hard disk fail at the same time.

        I think you might also be mistaking the performance benefits of Raid 5 as well. Raid 5 is slower than a standard raid 0 and single drive performance when doing random read/write, small file read/write by up to 1 order of magnitude. Also, at its best during long writes and long reads, a Raid 5 only performs as well as a bad raid 0. The raid 0 itself also only has questionable performance benefits over a fast single drive.

        I have an article here that is a good read. http://faq.storagereview.com/tiki-index.php?page=SingleDriveVsRaid0

        Well since you’ve invested so much time and effort into your raid, it’ll definitely be something to keep I guess. I used to run RAID drives too, which is why I know most of this :P, but… I eventually realized it just wasn’t worth it. All of the people I do know who were using RAIDs along with me have also switched back.

          thanks for taking the time to write that up ^^

          for the mirroring i guess i’m just not seeing a better alternative. i’m looking to backup my data onto at least 2 external disks, and the prospect of having to manage that extra copy just seemed like a hassle when i could have raid 1 do it for me. in this scenario it seems like i’d still be stressing the disks equally, raid or not, so i chose the laziness of raid. i guess given that particular goal… do you still think that raid 1 isn’t a good choice (or so much worse of a choice)? or perhaps is the goal the problem?

          i guess to summarize my completely insane desires:
          1. i want my data backed up on internal drives (currently a raid 5)
          2. i want my data backed up to external drives (currently a raid 1)
          3. i want my data backup up to media (using bluray… or will be, as soon as i start burning my first disk ^^;)

          i guess it’s kind of a hierarchy, with the internal drive backup for pretty much anything/everything… the external drive backups are relieved of some of the trivial stuff i don’t care as much about… and the media backups only for the super important (or collections that are complete in some way)

          given my troubles with raid 5… your point is definitely taken there. though i am using it under i suppose optimal conditions (mostly as a storage array for huge files)… even if i was getting a significant performance increase, as a storage array, performance isn’t too big of a concern. perhaps my next hard disk purchase will be some 2tb disks so i can easily migrate the data off my raid 5 ^^;;

          thanks again for the feedback, definitely some good points i need to consider…
