Seagate Hard Drives Explained - Ironwolf, EXOs, Barracuda and SkyHawk - What is the Difference?

hello and welcome back and today I want to talk about Seagate hard drives and I want to talk about the difference between it not only their entire range but when you want to choose a hard drive be it for nasbe inferred surveillance general data center youth you know even away from service when it comes to using desktop PCs different crimes will promote different results [Music] today I want to talk through some of the details that surround a number of these different hard drive series from Seagate to help you decide which one best suits your needs now it's worth highlighting as you can see on the screen my laptop is here on screen because a lot of the time the scripts for these videos it's either in bullet point form or I have a whole general knowledge of drives to take in but because this is such a widespread video and there's a hell of a lot of information to cover today I'm gonna need to have some of the reference materials right here in front of me and I'll try to keep some of these on screen for you guys as well but let's talk about the drives we're going to be featuring in today's video first and foremost probably the most familiar of them all the Barracuda series this is one of the earliest generation of traditional SATA drives from Seagate Barracuda typically and again there's going to be like kind of vague benchmarks here um typically designed for desktop PCs and single drive use and if for the most part the most affordable drive of all the drives here we're going to talk about today in drive I'm holding right now it's just a one terabyte drive but there are bigger drives and I believe these go all the way up to 14 maybe even 16 terabytes currently moving on from that we can talk about what the one that we might familiar with on this channel I want to talk about iron wolf I am warfarin this case this is a 40 be iron wolf but they're available in all the way up to 16 terabytes and these are our nares series of drives these are drives are designed to go inside network-attached storage devices and these are the ones that we talk about the channel the most because we talked about now's the most look at the brand's next staying in the subject of nerves we're going to talk about some do 300w all Freudian slip there Seagate I am warm Pro and this sigue arm wolf pro is for larger Nazz arrays that are going to be under a lot more pressure of utilisation and once where despite that huge over said overhead of performance and what's going on within the server all times these will still maintain a high read/write and operational value and obviously they are going to be more expensive than the traditional drives full care more details later on now stay on the subject of servers we can talk about a drive that is designed for a different kind of server these days this is a surveillance ride this is the Skyhawk series from CJ and these are the drives that you would put inside a nas or DVR or NPR device that's gonna write multiple drives inside and its primary if not only purpose is surveillance and there's lots of reasons why a surveillance drive inside and out is different to a nas drive in an ass but we'll cover that a little bit more later on and finally we can talk about the data center class of drives this is the Seagate X off series and the exosphere associate other drives are designed to go in high-end data center use they can of course much like all the other drives be utilized in many other sarter based Drive appliances but they come into their own when they are utilized in very very busy server environments where you need high read/write operations when things are going to be incredibly intense and the drives are being hammered with access at all times so those are the rods were talking about today and there was a huge amount of crossover between them now first thing we're going to talk about is price I did say that the Barracuda series is the cheapest by far and that's sort of true but because of the Seagate it's kind of demographic and the way the drives are spread out the Barracuda series have drives non-pro is only available up to a certain capacity once you reach a certain capacity level or drive so ugly currently around about their 10 to 12 TB mark Seagate Barracuda becomes a barracuda Pro and then it stops of being the cheapest Drive of all of these at that capacity level at 12 and 14 TB and that's because the pro series erson of this drive you kind of need and what professional drive chassis to maintain the enormous amount of capacity within those drives and alongside that everything from the cache utilization with it to the drive build itself and Barracuda Pro that's why it's the kind of the price goes up more than just a simple 4 6 8 10 12 14 TB once I hit that proxy his model and why these drives are constructed together things change dramatically in actual fact when it we reach 12 and 14 terabytes the lowest price drive amongst them and if you do check this out you might find that the Skyhawk these surveillance drive is the most affordable of all the drives here and that is because it's designed for a single purpose but the majority of the other drives that we're featuring here on the table being drives that are found in kind of more vague two or three tasks scenarios whereas a sky Hawk surveillance drive is designed for surveillance and surveillance alone what that means is these are designed for a much much heavier write action than read what that means real terms is a surveillance hard drive it's designed to be ready to receive data as much as possible it's designed to be used in a scenario and there's lots of cameras and particularly modern aei cameras which are pushing a hell of a mount a hell of a lot of data to the hard drive for storage surveillance Rives are designed to be rewritten to significantly more than they are to be read from what that means in basic terms they are designed to have cameras right and send a bunch of camera footage that you know minutes hours days weeks and months but that data is only gonna be accessed very periodically probably less than 5% and that's been generous I think about if you've got a camera outside your home or business chances are that camera is gonna be recording for days and you probably watch mere minutes fast forwarded even of the data that's on those discs and you still need to drive to continue being recorded - so surveillance drives are designed for far bigger right actions than read and that's the distinction and that's why their price is more negative Duvall than the others because whereas every other drive on this table can be used for lots of purposes you know effectively this surveillance drive is very targeted with a narrow field of utilization now the nares hard drives here both the standard and the pro are both with the same utilization but a slightly different method so the standard drive which is to be utilized in hard drive raid arrays of around five to eight disks and that is a little bit negligible it means that you can install a standard iron wolf nas drive in an ass server of up to five to eight disks and it will function very very well indeed but its construction is not designed with more enterprise utilization such as a 12 by 16 bay or a 24 by rackmount in mind the result being if you have multiple of Seco iron wolf standard now series drives in a much much bigger array they're not going to perform as well as they should and that because of the vibration sensors the heat sensors the the RPM and stuff like in the cache not being geared towards that large enterprise field now the drive itself arrived with three three years of manufacturer's warranty and once you and unless you get to about 10 maybe even 8 terabytes the majority is I'm arrived with fifty nine hundred rpm that is then up to 7200 rpm all the way up to 16 terabytes with the cache inside starting around 32 to 64 Meg and getting up to about 128 to 256 megabytes of cache it'll so rush that three years manufacturer's warranty and say iron wolf health management inside something I'll talk about a little bit more detail towards the end of the video but the Seagate buying wolf nas drive is still a very very very good drive but once you go into those bigger storage arrays once you're going to be really pounding that now's to read and write as much as you might need to in an enterprise level setting that's when the pro series crops up now the pretty much all Pro Series drives arrived with 7200 rpm as the speed in sign on top of that the cache is significantly higher each tier and although the throw series is clearly more expensive than the non pro the price between Pro and non Pro is only about 30 to 50 pounds with each tier and is actually the top tiers that the margin of difference between Pro and Pro baguettes lettuce only at the lower tiers where the price is quite large and that's because the larger tears of non-pro are still built white enterprise-level there you know the construction of the chassis is the RPM even the cash is heightened to a point that the price of production is a little bit closeted only in terms of harbor construction with a Pro Series drive but there's still lots of reasons why the Pro Series rather than the non Pro can be an optimal choice for business notwithstanding the fact that the vise arrives was five years of manufacturer's warranty not the three of the non Pro and along with the caching options and of course the iron wolf health management that again I will talk about at the end the pro series drive also arrives with two years of data recovery built into it and again we did some whole overview tests of this if you're drawing suffers mechanical failure if you lose data you need to recover or any one of many many ways in which you can lose data within a disc charges are it will be covered by the data recovery plan included with this drive and anyone that's ever had to use enterprise level data recovery will tell you it costs you thousands upon thousands of pounds to claim literal bits of data so that's one way in which pro series particularly prone ad series drives are very advantageous and of course unlike these drives which are designed a non-pro for around five to eight discs the pro series will go to sixteen go to twenty four bays it is designed for the long haul with vibration and temperature sensors as well as increase the data writes per day in comparison to the non pro series something we'll touch on a little bit more later on so where does that leave us that of course leave the exes series and the EPS off is quantitive feet data center class dried weirdly they found a great price point with the XO series because although it is an enterprise drive that is comparable in a number of ways cache rpm warranty construction with Seagate iron wolf pro it doesn't arrive with the data recovery services and somehow in that the price of a nexus can sometimes be less than that of a pro because of the way they kind of scaled and what's included on a physical and software level between these drives now don't get me wrong the exif series still gives you probably the best readwrite performance of any disc here on this table although the pro or sometimes come very very close or at some capacities even surpass that of a nexus but remember that a nexus drive is still designed for a data center it probably consumes the most power of all the discs here on this table let's go to the laptop if we make our way to power consumption we can see immediately that off all the drives on this table at the 14 TB limit the X off to juice the most power at well over 10 watts and think about that at 10 watts at the X off moving all the way down the table to 6.8 on the standard now stride that's a huge area of difference and I know it's still not much power but once you're looking at a device that got 10 20 drives and you think of the heat and the vibration that's generated from a drive it's worth highlighting there and the more goes from that that power increase is on everything from standby to active utilization an idle and hopefully we've got some graphics there on screen to show you now on top of that we can talk about the max read/write because let's face it a lot of us would want to talk about bare-bones read/write operations and unsurprisingly the performance of the XO's as mentioned is the highest of them all looking at it here with is 245 megabytes per second right on this drive which is great that's half an SSD which is pretty fantastic and if you compare that against the 196 of the standard barracuda that's a big big jump in performance between these drives so what do you advocate those drives in a raid array that's when you really see the performance benefits and if you're gonna utilize 10 gigabit and stuff like that on your array and it's also worth highlighting that the Barracuda drives are not designed for right they are not designed to be in multiple arrays of multiple barracudas or working together in a random array of independent disks right they don't have the vibration sensors they don't have the cache built in together to deal with data that's being spread across multiple drives at once it's one of the main reasons why people moved out from Barracuda from the early days when people were sticking these inside now it's because they were using the wrong tool for the job now of course all of these drives as mentioned we do have distinct price differences between them but there are other ways to go to drive because if you're going to buy a hard drive it's not just about how much how fast you can write data to it it's about you know that the capacity of the disk and what it can hold because at the moment all of the Seagate on seek a spectrum of drives are available at 14 and 16 terabytes with some great options available but in terms of failure rate in terms of reliability in terms of basically the robustness it has to be said that you when you spend a bit more you do seemingly get a great deal more reliability and robust build if you look at the Backblaze listings you know that are published periodically you will see the pro-series drives typically have much higher reliability don't get me wrong those numbers are suspect you know a little bit suspect because it's not like they use 500 or a thousand of every single drive you were looking at painted figures that you know they're open to interpretation with bad matches all the devices they're in there's lots of little legal points there but overall you do see a much higher mean time between failure the more across this table you go with 2.5 million at this end of the table and 1 million mtbf at this end of the table so it does grow in line with the price the same thing goes with data writes per day you can definitely write more data per day on the enterprise level drives and flush that day you're in rewrite and that's not just in terms of the speed at which you can write it but the robustness of those platters inside to take that data and in the arm and everything involved inside one this that we don't have on a table for example because they're still not commercially available is of course those hammer mac 2 drives with two actuators working inside alongside the the reading twice as much data with reading right being reported at around 480 megabytes per second and I'm looking forward to seeing what they look like because I thought we kind of maxed out right in terms of capacity but to be honest I thought we should concentrate more on speed rather than capacity but the Mac Siri seems to be giving us both currently available at 14 and 16 terabyte versions being planned now we talked about our rpm we've talked about caching we talked about price we talked about utilization let's wrap things up on what is the best drive on this table because let's be honest they're all conniver utilization so technically there is no best drive on this table we can't look at them and go all that one but what we can do is see which one's of these drives tick the most boxes I mean if we look at home now as users you know small prosumer your Falls and your 6v devices chances are you are going to do well with standard NAS Drive you definitely shouldn't go for a Barracuda as described earlier but if we look at for the small to medium now shooter song that's gonna spend around somewhere between a grand two grand on a complete solution with hard drives in a raid and a full band above we can look at these four we can kind of lose the bathrooms are from the equation the Skyhawk obviously if you're using a device just for surveillance go for the Skyhawk you need that heavy right low read action but if even if your device is gonna be surveillance and one other task go for the eyewall cuz Skyhawk if you're not you if you're using it for other things than surveillance those other things will suffer dearly with a heavy write low read return on operations with that disk now between the iron wolf and iron wolf wrote there is the school of thought that even if you are using even a two or a four by nose you should go straight for the probe because of the data recovery because of the increased rpm and caching and increased read and write speeds as well as the data recovery services are included inside but do bear in mind that one of the things that the Barracuda has that very few of these other drives and have is a low noise threshold of these drives here the Seagate of the Seagate iron wolf here is this is the lowest noise of these four drives and these drives here are the noisiest of the bunch and if you've got if you're gonna be in close proximity to announce you're not gonna want to go drugs it will drive you close to madness so you do get a lot of value from that but remember that word Enterprise enterprise in terms of construction remember the robustness of the design and the heavy nature of its design even one looking at the weight of these discs we can see that the barracuda drives weigh in significantly less at 14 TV than that of the X often because of that enterprise level construction so but now she uses in small to mid-range sure I wolf on wall pro there is your money but what about higher if you're gonna go into an 8 by or above it opens the door to choose between a pro drive and an exit and we're from here it's simply comes down to two things one are you know utilize the data recovery services or have contingency plans in place already you don't need it in that case if you do go X off you'll get a better value for money per terabyte and you still get incredibly robust strong drive overall however if the appeal of they increased coverage of the day recovery because both of these drives are 5 years of warranty but if the inclusion of the data recovery services appeals to you if you're not that bothered about mtbf but you are interested in things like data rights per day and a more balanced readwrite operation then maybe the pro for you and that's what it comes down to it's about buying a hard drive that you're getting the most performance out of and robustness because all of these drives will give you including the Barracuda will give you a great read and write and you are gonna get a good Drive that is gonna perform in a multitude of different ways but the more work you're going to do to the disk the more you need to have a distance prepared to take that work and that's why we're moving this well on the table based on just how much work you're gonna do now we are going to do a follow-up series rise with this well the videos where we're going to bench test each of these for at the same capacity level in similar scenarios this gonna take something like five weeks to get all that recording done so do bear in mind it may take a little bit longer than a simple week or two but I will get that done for you guys if you've got any questions or stuff that you want to see in that video or maybe some scenario and comparisons that could be tested logically do let me know in the comments and don't forget to click like if you've enjoyed this video so I know you do and I know how to keep going forward and click subscribe to learn more I'll see you next time
