MemoRight GT vs Mtron SSDs

Benchmark Reviews has published details about the MemoRight GT and Mtron high performance SSDs.

Here’s what I can gather. The MemoRight is 2x more the price of the Mtron. $32 per GB vs $16 per GB. I’m looking at NeoStore’s pricing to compute these numbers.

However, the MemoRight is 20% faster for reads and 25% faster for writes. Doesn’t make much sense to pay 100% more money for a 20-25% performance gain.

One thing to note is that the random write throughout might be 5x higher for this drive. The Mtron can only do 120 write IOPS but the MemoRight can do 500.

However, it might be a situation where you need to benchmark the drive.

At this point I’m not even considering switching. InnoDB’s CPU utilization turns out to be the bottleneck so upgrading our disk to a faster model doesn’t seem to make much sense.

    Kevin, in the actual benchmarks on that site, MemoRight was over 2x faster than Mtron in write speeds, not 25% faster.

    Also, it seems that you’re looking at Mtron Mobi pricing, not Mtron PRO. I’m not sure if the Mobi series is suitable for heavier use.

  3. OK… maybe I missed that part of the benchmark.

    2x is DEF worth it I would think. Especially for the SAME price and additional IO performance.

    I’m going to have to check this one out….

  4. Kevin,

    I will be providing another SSD roundup within the next week or so. As far as random read/write IOP testing I can give you some preliminary analysis. I have tested the Mtron Professional 16GB SSD to the tune of 109 IOP’s (100% random write, 20 I/O’s) and clost to 18,000 IOP’s (100% random read, 20 I/O’s).

    I just got my hands on the latest iteration of Memorights GT series. From some short testing last night the GT produced random write IOP’s of close to 600 and random read IOP’s of right around 9000.

    Short sum up: That would make the Memoright GT 5X faster than the Mtron Pro in random write situations. But, the Mtron Professional is still 2X faster than the Memoright GT in Random Read.

    Thanks for your continued support and patronage.

  5. has anyone tried EasyCo’s Managed Flash Technology? It is supposed to dramatically increase the speed of random writes, up to 20,000 per second for the mtron pro. That is redonkulous. It is a software layer under the file system. If it is legit I would think the implementation would be even faster in hardware.

    Even more amazing, when you do half reads and half writes, it can still handle 10,000 random IOPS. Ordinarily a solid state drive would crumble under this load. That is just plain nuts if true, and makes solid state a must-have for just about any DB.

    Folks if you want mind blowing read *and* write performance check out They only support linux at the present time. They use a method similar to STEC to achieve high write performance. They reserve some blocks for writes and then do some garbage collection (erases) in the background. So you end up buying more NAND RAM than you see, but you get killer write performance. It appears they’ve worked through some initial

    Hit submit too early…

    It appears they’ve worked through some initial production issues and have product to ship.

  8. Hey Bruce.

    Thanks for the pointer…… yeah. the Fusion IO stuff is nice.

    There’s a vendor that uses this log structure filesystem approach for the mtron drive too.

    I don’t think we’ll see this level of performance on SSD until 6Gbit SATA ships…

    What’s interesting is that you can only really see the Fusion IO performance in a distributed DB if you’re on 10gigE… on 1gigE you’re going to be bottlenecked on the NIC.

    The problem we’re running into now is that InnoDB quickly becomes CPU bound before we saturate disk IO…

    So for now SSD is about the max we can see …

    But I guess if you’re in KFS land you’re very happy :)
