    My macbook pro 15 inch early 2011 has a 120gb kingston ssd installed. I get about 100mb/s write and high 200's read. I have TRIM enabled. However, I see other ssd benchmarks reaching 4 and 500's, which is nowhere near what I am getting. I am running 10.11 right now but I was getting identical speeds while in regular Yosemite aswell. the ssd has a rated speed of over 500mb/s on write and read, and the sata interface is 3. I would love some help. [​IMG]

    This is what happens if you have a cheap SSD, Kingston SSDs are one of the worst in the market and they were caught baiting and switching customers with cheap NAND.

    Read this for more details, and it appears that your speeds are consistent with what AnandTech tested: http://www.anandtech.com/show/7763/an-update-to-kingston-ssdnow-v300-a-switch-to-slower-micron-nand

    You should consider having a far better Crucial BX100 instead. PS - you won't get anywhere near 500MB/s if your SSD is smaller than 250GB.

    I have been recently looking into SSDs and found some information on this as well. I had originally included a V300 in my considerations up until last night, but will be sticking with Crucial (I have an M4) or trying Samsung if I get a new drive.

    Kingston looks good as far as price and for some reason reviews, but the statistics are cringe worthy.

    They're pretty good too and slightly faster, albeit pricier.

    Slightly faster than that of the bx-100?

    I recommend the 250GB Crucial MX200. I had it in my 2012 cMBP and got good speeds.
    470 write and 510 read.

    If it weren't obvious in my first post here I will give a +1 to Crucial. The drive that I mentioned ownership of is approaching 3 years old now and it runs as quickly as when it was purchased.

    I buy just about everything from Crucial nowadays. Great company.
