Crucial M550 2.5" SATA SSD Full Capacity Roundup

Subject: Storage
Manufacturer:

Yapt

Yapt (yet another performance test) is a benchmark recommended by a pair of drive manufacturers and was incredibly difficult to locate as it hasn't been updated or used in quite some time.  That doesn't make it irrelevant by any means though, as the benchmark is quite useful.  It creates a test file of about 100 MB in size and runs both random and sequential read and write tests with it while changing the data I/O size in the process.  The results are a good look at overall drive performance.

Save the smallest capacity of the Crucial M550, we see fairly consistent performance across the board in YAPT. As an important note, this is not the same spread we saw with the ADATA SP920. Here's a look at the write specific results from that review:

There is clearly a difference in Crucial's firmware tuning and die count selections that are enabling higher performance, especially in the smaller capacities. While ADATA's models are comparable to Crucial in the 512GB and 1TB capacity points, ADATA falls short much faster in 256GB and especially so at the 128GB capacity.

To repeat an earlier point, YAPT is not a 4k aligned test, and the Intel SSD 730 has more of an issue with non-aligned writing than the other drives here, explaining the off results seen above.

You were all impressed with performance vs price for these 550 SSDs greater than 128Gb, and I tend to agree. The Samsung EVOs seem to be an additional $20-30, but the Samsung Magician software especially for firmware update notification is excellent. Does Crucial have software similar to Magician ? Because firmware updates are a pain.

Hey guys I just saw your video and I was wondering, I want to buy a M550 128gb SSD because its very affordable compared to the same one with 256gb. Write now my Acer Aspire has a 250gb HDD, its to slow, that's why I am changing to SSD, but the question is: is their a difference in speed between those two? I use my laptop for recording music and stuff like that and the speed is very important to me.

Is their a speed difference between the M550 128GB and the M550 256GB?
