got two contenders the WD red which is the original Naza optimized consumer grade hard drive and then we've got the new comer the Seagate NAS hard drive so what they both have going for them is longer warranty periods than a typical consumer grade device 24/7 tech support as well as a 24/7 rated ab sort of operational workload that's that's what they're designed for it actually be used all the time in a storage appliance they're both optimized for smaller rate enclosures so for example the red is good for anywhere from 1 to 5 driver rays and there's a reason for that because as much as I have always used just regular desktop drives in naz's both Seagate and WD have lectured me about this because they're like well actually the vibrations that are passed between the drives can be a problem in the longer term particularly when you pile more and more drives into an enclosure so having drives that are optimized for resisting any errors that might be caused by that vibration is definitely a positive positive thing the one key difference between these drives is that the WD red does tend to be a little bit more expensive on retailer shelves and is only available on a 3 terabyte capacity up until now and performance of these drives in Nazz enclosures is very much an unknown at this point not too many people have really looked into it so we decided to take a Synology ds4 11 so this is their DiskStation quad bay enclosure we've set up a raid 5 in there with either 4 of the red 3 terabytes or 4 of the Seagate NAS Drive 4 terabytes and decided to run some benchmarks because many people are looking at these Navs drives going oh well they only run at 5400 or 5900 or whatever sort of eco optimized rpm because remember in an AZ enclosure you want less power consumption and you want less power consumption did I say power consumption twice because what I meant to say was heat output for the second thing you want less of both of those things so running at a lower rpm as helped achieve that but what does that do to performance well I'll tell you what we were expecting to happen is we were expecting the land interface right there that Gigabit LAN interface to be the first bottleneck even running in something like a RAID one configuration which is to drive redundancy no calculations we are looking at about I mean we're looking at a maximum of 80 to 100 megabytes per second transfer speeds if we're running in something like a raid 5 for writes we'll be lucky to get 25 to 35 megabytes per second write speeds which means that a 50 900 rpm drive can keep up just fine so the other bottleneck like I said in raid 5 is going to be internally here the processor raid 5 is very calculation intensive so basically what you do is you have at least three drives and one of the drives worth of space is allocated for a parity bit which is pretty much a song that someone designs to sound like another song and then they actually change the lyrics to make it more comical no no not that kind of parity the real parity is data that can be used to reconstruct the data on the other drive so it's extremely cut computation intensive when it comes particularly to writing data to a raid array anyway without further ado I'm going to put some charts and graphs up on the screen that'll give you guys some idea but performance differences we observed which I think really backs up our hypothesis in a very big way we ran several different tests including real-world small medium and large file copy tests and all of these numbers are reported in the time it took to complete the operations with either different set of drives and then we also ran black magics disk speed test which we've found to be a fairly reproducible and just kind of a quick and dirty benchmark so that gives you a synthetic benchmark as well as a real-world benchmark to show you that we really didn't observe a difference in performance between these drives so with no real performance difference between the drives how do you pick which one to go with and I think the answer is that it comes down to trust who do you have the best experiences with over the longer term or the people you know or whatever else do you want to pay more for the WD or do you want to pay less for the Seagate or do you need the four terabyte capacity that's available in the Seagate WD doesn't have a four terabyte read yet so there's all those things to consider I know slick just recently purchased four of the 3 terabyte WD Reds for a personal raid array so that should give you some idea what we think of the red particularly internally here and speaking of things that we think very highly of internally hear audible calm so check out audible.com slash Linus you can get yourself a free audiobook by signing

whether it's older stuff business stuff or the latest bestseller so for example I was just checking out the Cuckoo's calling by Robert Galbraith or Galbraith or Goliath whatever it doesn't matter not a real person if you don't know this already Robert Galbraith is actually a pen name that was being used by JK Rowling so there's a big controversy and all that it was very well reviewed but wasn't selling particularly well until all of a sudden it leaked and someone told someone who told someone in anyway the point is now it's all over the Internet's critically acclaimed even before we knew it was JK Rowling and receiving extremely good reviews even now that we do know that it's JK Rowling who wrote this particular book so it's kind of a mystery so no no magic or anything like that and I do recommend checking that out guys if you go ahead and redeem your free audio bootable comm / Linus go check it out right now thanks for watching this episode of Linus tech tips on him Nazz drives
