Micron C400 mSATA (128GB) SSD Review
by Anand Lal Shimpi on April 10, 2012 8:00 AM ESTTRIM 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.

lol boot time and how fast it loads a program? They **ALL** load windows in about 15 seconds from a clean install and all programs open in less than 3 seconds. Photoshop maybe 4. That would be the most retarded benchmark I have ever heard of doing to get a real grasp on how fast these things are and the actual difference between them.If you understand anything about this stuff, you can determine real world performance from the numbers given. This isnt the old days with screwed up random reads anymore. Look at the I/O ability and get with the program.

If they **ALL** load Windows and boot programs at the same speed, what does that say about all these graphs that show alleged large differences? (it says they're bunk, misleading, and stupid) Why do you defend synthetic benchmarks that have no relevance to reality?mikbe - Wednesday, April 11, 2012 - link
"Moore's Law ensures that large SSDs can be delivered in small packages."Moore's Law is an inductive observation not an actual law of physics so it doesn't ensure anything.

That's also what I thought when I read that.UltraTech79 - Sunday, April 15, 2012 - link

Boy, would I like to win one these boards! It would be a nice start to a new build.asawyer13 - Tuesday, June 26, 2012 - link
I am looking at purchasing a higher end Dell XPS 15 laptop. It comes w3rd gen I7 cpu, and 1tb 5400 rpm drive + 128GB mSata drive.Would it be possible and does it make sense to replace the 1TB 5400 drive with a Crucial m4 512GB SSD???
Thanks
