Transcend SSD340 256 GB Review: Now With JMicron Inside

How We Tested Transcend's SSD340

Our consumer storage test bench is based on Intel's Z77 Platform Controller Hub paired with an Intel Core i5-2400 CPU. Intel's 6- and 7-series chipsets are virtually identical from a storage perspective. We're standardizing on older RST 10.6.1002 drivers for the foreseeable future.

Updates to the RST driver package occasionally result in subtle performance changes. They can also lead to some truly profound variance in scores and results as well, depending on the revision. Some versions flush writes more or less frequently. Others work better in RAID situations. Builds 11.2 and newer support TRIM in RAID as well. Regardless, results obtained with one revision may or may not be comparable to results obtained with another, so sticking with one version across all testing is mandatory.

    A lot of new SSDs lately on Tom's. Where are the DDR4 SDRAM reviews?

    Should the Sequential chart be in MB/s instead of IOPS?

    Great article, much appreciated!

    In the conclusion you put:
    the M500 has one feature the SSD340 lacks: TCG Opal 2.0 and Microsoft eDrive support


    That would be two features!

    There is a good chance you won’t notice the difference between a “fast” SSD and a hard disk in the day to day life of a PC.

    I don't think that's accurate. I have two otherwise-identical laptops, one with an SSD for its boot drive and one with a HDD. The one with the SSD is hands down faster in program launches, file opening, and other read/write tasks.

    I've also compared fresh installs of multiple OSs (Windows 7, Linux Mint 16, Ubuntu 14.04) between hard drive and SSD, as well as comparing them to my old Windows 7 install on a relatively slow SSD, and none of the fresh installs on hard drives even came close in speed to the old and bloated install on the SSD.

    I'm sorry that you haven't experienced the difference between a SSD and a HDD, I do truly believe it is the single most important upgrade one can make to their PC.

    Lots of upgrades can be important depending where you are at with each component. If you have a slow low power 2.5” hard disk in your laptop then an SSD can help. But I’m looking at all other things being equal and SSDs just don’t help that much when you have a fast 3.5” HD. When I compare the same tasks on my old PC with a HD that has a good 150MB+ read write speed and other than benchmarking the Windows boot time and a few large apps starting up it just not a big deal. Even then you have to clock it and see that it took 30 seconds and not 38. In my day to day work I just don’t notice. You have to set there and clock the Windows startup time. Are my work VMware sessions any faster, do my games start any faster? No, not really. I have even played around with a 50GB RAM drive with 3000MB+ read/write speeds and my games and VMware sessions are just about the same. Windows and the apps are waiting on other things and the bottleneck is just moved elsewhere. All my games are on my supper fast 400MB+ SSD and when my friend comes over he plays on my poor old HD base PC with slower RAM and slower CPU and a slower GPU and all the different games we play together I load the games maybe a few seconds before he does and with some games there is no difference.

    Tanguen thats because your slow machine isn't loading the full size textures, meches and running the game on maxed settings. Can't you just think about it before talking from your *!#.

    Your almost never going to be doing sequential write/read for 150MB+ on a HDD and that random read/write will just kill that speed.
