TRIM Performance

To ensure TRIM's functionality and understand the SSD's behavior in a highly fragmented state I wrote sequential data across all user addressable LBAs and then wrote random data (4KB, QD=32) for 20 minutes across all LBAs. Finally I used HDTach to give me a simple visualization of write performance across all available LBAs (aka the Malventano Method):

This pattern is what we've come to expect from the C400/m4. TRIMing the drive completely restores performance of course, but if you're running a highly random workload you're going to see a fairly sharp drop off in performance as the C400/m4 were really only designed for client workloads.

    Is conclusion page missing? or it is not present intentionally.

    Same as the last article... this one is just a refresher so all the conclusions are on the first page and the rest are just backup data.

    That's a neat way of doing it.

    I hope Anandtech can still do in-depth looks at important products, but this format is a happy medium for less important products that still deserve a review.

    I agree. I like the format. They could probably tell from access logs that a lot of readers do what I do: read the first page (introduction), then read the last page (conclusion), skipping everything in between. It makes life easier, even if costs you a page of ad impressions.

    ....and that's the truth of it. I agree!

    I like the layout also. Though you'll get less ad revenue when I skip the rest of the pages. ;)

    I agree and hope to see some of the mobo reviews follow suit, after the nice and complete initial chipset analysis reviews you don't really need a full blown review, just the basics.

    I don't think so. When you're reading something that's interesting, I think you tend to check out the ads more than when you're just scrolling down pages of benchmarks.

    i only use the Print page button (do not print it) as it makes all the pages onto one page (wish other sites would do it) so its only 1 page change

    i prefer to have one full page that's just me
