Crucial M550 2.5" SATA SSD Full Capacity Roundup

Subject: Storage
Manufacturer:

HDTune

HDTune tests a similar level of features as compared with HDTach, but with a different access pattern. Thus provides us with an additional set of benchmark numbers to compare between storage configurations. Here we can get the minimum, maximum and average transfer rates as well as the burst rates and access times. CPU utilization has proven negligible with modern processing horsepower, and is no longer included.

HDTune's burst test gives inconsistent results. Posted here for information only.

All modern SSDs have no issue saturating their SATA 6Gb/sec link. No difference here with the M550's.

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?

I agree, but it's not just the cost - it is also the capacity, power, and suitability for video recording. Low-power, video/surveillance 3.5" drives are available up to 6TB now, while 2.5" drives tend to max out at 2TB. If you are building a DVR which can record 6 or more programs at once, supporting 1 or 2 3.5" hard drives (as the reviewer showed) makes a lot more sense than using four 2.5" drives.
