Performance vs. Transfer Size

ATTO is a useful tool for quickly benchmarking performance across various transfer sizes. You can get the complete data set in Bench. Both read and write performance are actually on par with the Extreme Pro, which is impressive. That is explained by nCache 2.0 because ATTO only writes 2GB of data, so the Ultra II has no problem of caching all the writes to its 10GB SLC cache.

    I think we can safely assume any off the shelf/factory based hardware encryption has backdoors by NSA/GCHQ or Chineese intelligence or whoever. So it doesn't protect from governments nor government sponsored industrial espionage. In the best case it protects from information leaks in case of casual theft. At worst, it gives a false sense of security.

    I would never rely on anything except open-source encryption where the source is continuously being reviewed. And even that is can be compromised by introducing hard to detect bugs.

    So I don't think hardware encryption support adds much value if any.

    Can we just cut the reviews for SATA based SSDs down purely to "What makes this SSD radically different to 99% of the similar performing SSDs out there"? Would just save a bit of time that's all. SSDs are now like RAM, all much of a muchness and we just need to know the bells and whistles if any. Reply

    SSDs are way different than RAM is. RAM is managed by a controller that is integrated to the CPU, so the DRAM you buy is basically a bunch of dummy silicon with no logic in itself. If SSDs were just a stick of NAND, then you would be correct, but the truth is that SSDs have a controller and firmware, which makes one SSD different from the other. In addition, NAND is much more complex to manage compared to DRAM because you have all sorts of limitations (page is the minimum write and you can only erase blocks etc.), so there is much more to it than with RAM, which is basically just differently binned pieces of DRAM silicon.

    We could drop all component reviews if we took your mindset because current computers can do pretty much everything that average users want them to do. However, the fact is that there are people who are interested in the details and how things work, and there are people who do more than just web browsing and email, so that is where detailed reviews are needed.

    StorageReview basically stopped reviewing consumer-grade drives for most second and third tier manufacturers because they got tired of writing reviews that said, "Yep, it's another Sandforce reference design, and it pretty much performs the same as all the others." Reply

    I feel that Anand is praising the MX100 just a little bit too much. I had to first hand experience that it's not that good (even for a budget drive). Those bad service times you measure on the MX100 are really noticable in real life usage.
    In my case, five identical i5 machines. Four with 256GB MX100 drives. One with a PNY 240GB Optima (was even cheaper than the MX100). During heavy work, the machine with the Optima was clearly snappier. And I don't mean I measured higher MB/s but snappier. Everything you open just starts to happen/load a little sooner.
    This shows that your reviews for low-end consumer SSDs are too workstation/server minded. The fact that the MX100 start being faster than the Ultra II after a barrage of 10GB of random data, means basically nothing for a casual desktop user. The usual desktop usage is small burst of data. Lots of idle time. You want those burst to happen/start fast.
    You keep pushing encryption as a pro (and it is one) but keep in mind that probably less than 1% of people actually use it.
    My advice? Both the M500 and MX100 are laggy. Drives with Phison controllers are laggy. Transcend SSD 340 (JMicron) felt laggy like the M500.
    PNY Optima didn't feel laggy. Sandisk Ultra Plus didn't feel too laggy either (not perfect though).
    I'm eager to test the Ultra II and the Hynix SH910A (because the Neutron felt so smooth).
    I don't know how you're going to measure this through benchmarks (well the service time one seems to show it) but my brain surely is perceptible to this.

    I smell bullshit or defective drives. There is no way, mx100 or m500 for that matter would fell as laggy as phison or jmicron for that matter. Both of those controllers are far inferior to marvell offering. In fact, some older jmicrons and phisons are so bad, that it doesn't even take a heavy user to notice the difference or lag. Reply
  • milli - Wednesday, September 17, 2014 - link

    Yes, true. I've got dozens of broken drives. ;) Seriously, no bullshit.
    Obviously I'm talking about drives with JMicron and Phison controllers from 2014 and not the older ones.
    Also with laggy I don't mean that I'm waiting seconds, right! As an enthusiast and professional of plus 20 years, a couple fractions of a second make them feel more laggy to me.
  • hojnikb - Wednesday, September 17, 2014 - link

    Well, considering the workload you have, why didn't you go with more expensive drives in the first place ?

    I mean, those drives are not exactly meant for heavy work you're describing.

    If one of them does it significantly better than the others, that's something worth noting. Especially if it doesn't show in the benchmarks we're used to looking at. Reply

    Very true what you say but the clients these machines are meant for, use it for light usage. It's only during preparation of these machines that I notice the differences. The only reason I used the MX100, is because of Anand's recommendation. At first I was skeptical about it because of the M500. It seems that skepticism was just. There are better client usage cheap drives out there. Reply
