    I always like a good review, but I'm finding SSD benchmarks difficult to respect when the real-world difference between this drive and the MX100 will be invisible to most users. Reply
  • Samus - Tuesday, June 17, 2014 - link

    I agree, Ferrari's vs Lamborghini's. Anybody coming from a hard drive or even a last-gen SSD (like an Intel X25) isn't going to notice the difference between a $100 MX100 and a $200 Sandisk Extreme Pro Reply
  • nathanddrews - Tuesday, June 17, 2014 - link

    No one will notice... except people that can and do distinguish between Ferraris and Lambos. I would imagine that someone that could tell the difference between a WD Velociraptor and a Seagate Barracuda would notice the difference between these two drives. Different users have different needs, that should be obvious. Reply
  • MyrddinE - Tuesday, June 17, 2014 - link

    The issue is that many power users *think* they can tell the difference, but fail to in blind tests. This has been proven true frequently, usually in relation to more subjective domains like audio, but it applies everywhere. Sit a user at two computers, one overclocked 5%, one not, and it's likely not a single power user will be able to tell without a FPS meter or perf test result. Reply
  • nathanddrews - Tuesday, June 17, 2014 - link

    Depends on what operation is boosted by 5%. If 5% allows you to maintain solid vsync vs dips, then you sure as heck will be able to tell. If 5% is the difference between completing 5% more editing projects in the same amount of time, then people who spend more will see a benefit. There's always a case to be made for measurable improvements.

    I'm sorry, but the audiophile straw man doesn't apply here.

    A 5 % performance difference with selective benchmarks using higher end SSD WON'T be noticed in real world user experiences. No need to apologize. Reply
  • Kristian Vättö - Tuesday, June 17, 2014 - link

    5%? The difference between 240GB Extreme Pro and 256GB MX100 is more like 162% in the Storage Bench 2013...

    Bear in mind that that's real-world IOs played back on the drive, so it's not as synthetic as e.g. Iometer tests are.
  • TheWrongChristian - Wednesday, June 18, 2014 - link

    It's entirely synthetic, even if derived from real trace data.

    As I understand it, the trace is replayed as fast as possible. In the real world, the trace probably would have been collected over a period of hours or days. In those time frames, different levels of near instantaneous is the same if it's too quick for human perception. Consider the microcontroller controlling your washing machine. It does all it needs to do fast enough, that adding a 10000% faster CPU won;t make your washing clean any quicker.

    Plus, in the real world, other factors come into play. Had the trace been replayed in real time (as in takes as long to replay as to collect, pauses and all) different drives will do things like background GC, which will improve performance of the next burst of activity. A drive that takes 162% as long to replay the trace at full speed may complete the real time trace within milliseconds of the faster drive. Result, no perceptible difference to the user.
  • Kristian Vättö - Wednesday, June 18, 2014 - link

    Maximum idle time (i.e. when QD=0) is set to 25 seconds, otherwise the trace is played as it was collected. Sure that's still not the same as playing it back in real time but it's still quite a bit of time for the SSD to do GC. Reply

    Where can I find these 10000% washing machines? I have been tracking this market for years, and I am so tired of incremental 5% gains on washing machine silicon. WE WANT INNOVATION!!! Reply
  • brucek2 - Tuesday, June 17, 2014 - link

    Its discussions like this that make it hard for me to get a feel for whether it would matter to me or not.

    On the one hand, 162% sounds plenty substantial. I do not want to spend 162% more immersion-breaking time twiddling my thumbs waiting for the next level to load, let alone 162% more time to get through a compile so I can meet my next deadline.

    On the other hand, waiting 1/1,000th of a second does not actually sound any faster to me than waiting 1/4,000th of a second (these are the "average service times" in the benchmark), because I know my personal threshold for perceiving laggy response kicks in at around 0.1 seconds.

    So where does this leave me? Not sure really but in the case of doubt it probably goes to spend more. The extra $100-$200 of potential hardware savings would be eaten up quickly in my time to research it much further, to end up ordering & installing & migrating to another drive sooner than I otherwise would have, or if I really did end up twiddling my thumbs more.

    But never fear MyrddinE, I'm still not buying the 99.8% pure unicorn dust super connect audio cables.

    There are plenty of use cases where every little helps - a 5% overclock, assuming linear scaling, would shave ~8.5 minutes off a 3 hour video transcoding task for example. Reply
  • UltraTech79 - Sunday, June 29, 2014 - link

    See but actual users do not do "blind tests" they do actual tests for their servers to see what is better. You dont need to feel the difference between 5 and 10 to know what number is higher. Reply
  • n13L5 - Thursday, December 03, 2015 - link

    In many cases, you are correct. But if you were just teetering near sufficient performance, a 5% performance increase to stay solidly just above 30 fps, the difference will suddenly become very obvious to perceive. Reply

    Well, I am just a simple architect, and probably I am not representative of Anandtech userbase, but, why do you feel hardware encryption is so important? Am I missing something? Should I be worried that my hard drives are not encrypted? Reply
  • r3loaded - Monday, June 16, 2014 - link

    I'm wondering about the focus on encryption too. I have a Samsung Evo in my Sandy Bridge desktop machine and it supposedly supports this Opal hardware encryption. Trouble is, I have no idea how to enable it. Apparently, I can set a disk password but I see no option for that in my computer's firmware. Someone mentioned enabling BitLocker in Windows 8.1, but I get an error message saying my system doesn't have a TPM chip. I have zero idea how to go about enabling it on Linux, but I suppose dm-crypt for software encryption should work just fine. Reply
  • andychow - Monday, June 16, 2014 - link

    I don't get it either. If your file system is not encrypted, then simply plugin the ssd to another machine and get all the data. If your file system is encrypted, then what does it matter if the hardware is encrypted? I think they just offer it because it costs them almost nothing to have a hardware encryption chip, and enterprises like buzzwords.

    @reloaded, you don't have to enable it, it's always on. The password is on the controller, if you destroy that, the data could not be recuperated. But why would you destroy the controller and not the rest of the drive is beyond me.

    I personally don't see the point.
  • chiechien - Tuesday, June 17, 2014 - link

    Your BIOS has to support disk passwords, and you have to enable it. For drives with hardware encryption, the ATA/disk/whatever password has to be known to get at the encryption key, otherwise it's just left at some default that every machine can read. Reply
  • Kristian Vättö - Tuesday, June 17, 2014 - link

    Hardware encryption means that the encryption is done by the hardware rather than software. The benefit is that because it's done at the device-level, it doesn't consume the host CPU like software encryption and it's more secure.

    While SSDs often encrypt all data that is written to them, you still have to enable encryption from the host to ensure that the data can't be accessed by a third party. Otherwise the SSD think that any machine (and user) is allowed to access the data.
  • thomas-hrb - Monday, June 16, 2014 - link

    Good point, personally encryption at the hardware level is not important to me. I find common sense and protection of property out weighs the continuous management overhead of encryption keys especially for a developer like me who regularly and repeatedly reformats partitions.

    Especially when working with cloudbased/corporate share online only storage. I do wonder however, I have a samsung 840 pro (256GIB version) I have 2 vertex4's (256 GiB version). I have on many occasions rebuilt/reformatted and transplanted my SSD's from one machine to the next. I don't know if I have to explicitly enable/disable the feature on the SSD, but IMHO, if I could easily read the SSD contents simply by moving it to another computer, then what ever encryption is on the drive is simply not effective.
  • chiechien - Tuesday, June 17, 2014 - link

    The Samsung (and probably the Vertex) encrypts (just by the nature of how it works) everything that is written to the drive as a matter of course. Unless you set an ATA password in your BIOS, though, the password/encryption key/whatever is left 'blank' or default or whatever, so it is readable by any other motherboard. If you set an ATA password, though, that changes the encryption key, you will probably have to wipe the drive to enable it, and then the drive will not be readable in another system unless you also configure it for ATA passwords as well, and then type it in.

    It's a great warranty but I think ssds potential failure points are less than an hdd. (my speculation).

    I'd still choose the MX100 over this any day. It's not like these drives are falling apart everywhere.

    How exactly is this a no compromise drive when it doesn't offer encryption and it doesn't offer capaciyor-based power loss protection? Data integrity and security seem like pretty big compromises. Or is the SLC buffer seen as a sufficient substitute for a capacitor-based solution? Reply
  • BillyONeal - Monday, June 16, 2014 - link

    It is a no compromise drive for the market it targets -- the consumer market. Few / no consumer-targeted drives have capacitors; pretty much all such drives are targeting the server market, such as Intel's SSD DC3700. Very few consumer drives offer TCG Opal, but some do, e.g. Samsung's 840 EVO. Reply
  • binarycrusader - Monday, June 16, 2014 - link

    The author specifically mentioned disappointment at the lack of encryption, and the author, unlike you specifically used the phrase "only no compromise high-end SSD in the market" while simultaneously declaring Intel's 730 SSD, OCZ's Vector 150, and Samsung 840 Pro as being in that same "high-end" market. So it seemed rightfully bizarre to simultaneously proclaim it as a "no compromises" drive given the other drives the author also compared it to that are supposedly in the same market.

    Also, while you're right that few consumer-targeted drives have capacitors, the Crucial M500 does. And honestly, capacitors don't cost that much, but it's no wonder Intel's happy to let all of the other manufacturers fight over "razor-thin" margins.
  • Kristian Vättö - Tuesday, June 17, 2014 - link

    Because the Extreme Pro is the only high-end SSD without the compromises that the three other SSDs have. Intel SSD 730 and OCZ Vector 150 don't support any form of low-power states and are thus not suitable for laptops. The 840 Pro, on the other hand, lacks IO consistency. All three drives are in the same high-end performance market, thus I'm comparing the Extreme Pro with them.

    Crucial's drives have capacitors that provide power loss protection but they are the only drives along with Intel's SSD 730. However, you can get away without capacitors if the firmware is designed not to rely too much on the DRAM cache. I would certainly like to see OEMs use capacitors more in consumer-grade drives but on the other hand, I'm not sure if I consider it to be that big of a deal. We don't have a proper way to test power losses, so I don't want to give too much value to a feature that may or may not be needed.
  • binarycrusader - Tuesday, June 17, 2014 - link

    Thanks, that explanation makes the comparison seems a lot more reasonable.

    By the way, NewEgg is selling the 480GB model for $379.99 today, which makes the Intel one slightly more appealing.
  • binarycrusader - Tuesday, June 17, 2014 - link

    There's still a DRAM cache though, so I'd like to see a torture test on SanDisk's drive before I could be confident. But I'm aware that's potentially bricking the drive so I can understand why you might not be able to do that.

    I agree that what SanDisk has done seems like it would help mitigate the need for a capacitor, but I just can't be confident about it until some tests are done.

  • jameskatt - Tuesday, June 17, 2014 - link

    Encryption is always going to slow down your drive. After all, it takes a lot of brute computation to do encryption.

    The biggest problem of hardware encryption is that you don't have the freedom to select your own encryption algorithm. For example, if the hardware encryption method is compromised then you are screwed if you rely on it.

    I would rather keep whole disk encryption at the OS level.
  • TheWrongChristian - Wednesday, June 18, 2014 - link

    Encryption in hardware is easy (at least easier than software) and probably adds very little in terms of latency and power budget. AES is just multiple rounds of XOR, ROM lookups and bit mixing. Quite easy to do in hardware quickly.

    AES-128 (the minimum AES level) is a long way from being considered broken.

    What's going to keep PCIe SSD adoption low is the sheer number of systems that you can't just drop it in and boot in it's current state.

The latest EFI updates for NVE and Windows 8.1 are a great step forward though. Reply
  • zuiop - Tuesday, June 17, 2014 - link

    Can somebody explain to me why in most SSD reviews the lack of encryption support is criticised? Of course you want encryption for your data, but why in the drive? It's a black box implementation that you can't fully trust or update, unlike the plenty of open source software solutions. Especially when talking about high performance drives, I'd expect the CPU to have hardware acceleration for encryption, so speed shouldn't be an issue afaict. Can anybody shed some light on this? Reply
  • Kristian Vättö - Tuesday, June 17, 2014 - link

    Software encryption adds unnecessary overhead and thus degrades performance:

    I think I need to do an article that better describes the usefulness of TCG Opal because there are some security advantages as well. I admit that we probably haven't done the best to fully address this, but hopefully we can still fix it :)

    Thanks for your reply. I'd love to see the article. I couldn't see from that linked article whether the CPU has AES NI or equivalent, my point is that I can't see why encrypting the data with such a CPU is inferior to drive side encryption. I'm looking forward to the article! Reply

    Kristian, just curious, why did the Vector 512GB top the IOMeter Sequential
    Write table? Just seems a bit of an oddity given where it ends up in all the
    other tables.

    Btw, your AS-SSD tables are amusing in this regard; I ran AS-SSD on my
    Vector 512GB, it gave 516.94 seq. read, 502.78 seq. write (topping both
    tables), overall score of 1091. Interestingly, although my Vector 128GB
    drops its seq. write to 386, the seq. read still stays healthy at 515.18.
    I do like the Vector series, they work very well. I bought a Vector-150
    128GB; it's seq. write is 10% higher, but the 4K numbers are lower,
    resulting in a reduced overall score (989 vs. 1040).

    The highest overall score I've had so far was 1147 from an 840 Pro 512GB.

    Vectors are great for AE cache drives (ditto Vertex4), though my 2700K does

    Pretty decent; not as quick/smooth as my 3930K's 840 250GB, though an AS-SSD
    run is good:

Now the 240 and 480 GB models are in stock for $270 and $400, respectively. All three models are in stock at with prices of $240, $430, and $700.

    The SSD market is looking like what we often see in the CPU market, with large price premiums for the fastest models. I won't be buying a Sandisk Extreme Pro, but there probably are people who could really benefit from the performance.

    Interesting, the price went up..

    The 240GB model is cheaper in Amazon now compared to newegg
    ( A vs. NE ) : $229.99 vs. $269.95 or $0.958/GB vs. $1.125/GB

    The 480GB model is cheaper in newegg
    ( A vs. NE ) : $429.99 vs. $399.95 or $0.896/GB vs. $0.833/GB

    The 960GB model is not available in newegg.. but it cost $699.99 or $0.729/GB in Amazon

    "SanDisk is turning out to be a very dangerous player in the client SSD space. With nearly perfect vertical integration model (they just lack client controller silicon and DRAM), SanDisk has the ability to put against Samsung and Intel who have traditionally held the performance crown."

    They actually do have their own controller. The U110 and the Standard (and maybe more) use Sandisk's own controller. Granted these are low end.

    Hi, shouldn't writes be slower than reads in drives, more so in SSDs? For eg, on sequential read for the Extreme Pro 960GB is 438 MBps while sequential write is 371.4. But in the case of random read(98.5) vs write(257MBps for QD=1), write is faster. Why is that the case? Reply

    Well, I don't understand very well how or why the SanDisk Extreme Pro and SanDisk Extreme II finish in front in AnandTech Storage Bench 2013 when it seemed to me that Samsung 840 Pro outperforms the SanDisk Extreme II by some distance (according to other websites) in terms of 4K write I/O operations. I saw 90K against 30K for the SanDisk in one test and 90K against 60K in another.

    Is it the mix of both types of operation (read/write) that makes the difference or is the AnandTech Storage Bench 2013 using more intensively non-4K read/write operations where perhaps the SanDisk SSDs perform better ? And would it be possible to have some results for the Samsung 840 Pro 256Gb in AnandTech Storage Bench 2013 please if the SSD is still available for testing ? :) Thanks :)

    And finally, I hesitate between the SanDisk Extreme Pro 256Gb (150€ here in France) and the Samsung 840 Pro 256Gb (165€). 10 year warranty sound really good but which one is better in terms of pure performance ? Which one should I take ? Reply

    I don't understand. In this review it says that the Sandisk Extreme Pro is the fastest SSD available yet when you go to the "Bench" area of this website, pick the Extreme Pro and put it up against something like the Samsung 840 Pro, the Samsung wins in many of the benchmarks. Even when put up against the Sandisk Extreme II the newer Extremem Pro loses out in many of the marks. I'm just looking for the all around fastest 240/256GB SSD but it seems every site I go to has a different opinion. Reply

    Some people complain about real-world difference between ssd drives (because drives are fast enough). Nah, thay arent :). I can tell that my 240GB hyperx is better than most 7k rpm drives, but its a turtle wgen compared to ramdrive. I cutted off 25GB partition from 32Gb of total memory to do some special things and i see huge difference. Installation a windows 2012 r2 with sql 2012 on hyper-v? Its a matter of minutes (i7 3770 @ 4.1). Benchmarks? Who needs them when you have powershell [get-counter -Counter '\process(_total)\io data operations/sec']. I used ramdrives on dell r820 filled with ram and can tell this: the slowest part of pc/server is and will be cpu :). Reply

    Hi Hardware Community,
    I know this article is quite outdated right now, nevertheless the actual topic of the authors "Final Words" bug me right now. Especially now that enough time for longtime-endurance tests has passed.

    Anyway, I can´t choose between the Samsung EVO 850 1TB v2 (289€) and die SanDisk Extreme 960GB (281€).
    So pricewise the "Pro" is even cheaper right now compared to the Samsung. But there are some obvious differences:

    - TLC 3D V-NAND vs. MLC Planar
    - 5 years vs. 10 years warranty
    - 150 TBW vs. 80 TBW
    - higher Peak vs. consistency
    - Samsung Bugging vs. sudden death drives

    My usage:
    - Client for everything: gaming, programming, office, multimedia - averything
    - gonna split it in system and data-partition
    - gonne be in laptop that´s used as desktop
    - battery is wasted, so no concern about power consumption

    So, usually I use hardware until it´s broken so meaning about 8-10 years.
    Still I want steady performance without sudden decline in speed like with the EVO 840 :C
    I´d be really glad, if you could tell me your opinion on this :)
