SSD odd performance

[SMSSMS]

So I purchased a crucial MX100, 512GB, as an upgrade for my laptop (inspiron 7537). I cloned my old HDD and installed and it worked fine.

I used CrystalDiskMark and the benchmark results showed similar results to all that's out there. So everything should be fine.

However, when I tried to make a copy of a music folder (3GB), the copy rates start really good at (350MB/s), but then after 20% of the data is copied, then the performance degrades significantly, it goes down to 20 MB/s and then exhibits a sawtooth pattern going up from 20 to 120MB/s then down to 20 again and so on.

What's the matter?! (btw, the SSD is 70% full)

Hey SMSSMS. I'd recommend that you try the SSD with a different computer or a different SATA connection to see if the same thing happens again. You could also go to the manufacturer's website and see if there are any firmware updates available and install them to see if this fixes the issue.

If nothing works for you I'd recommend that you contact the manufacturer's customer support directly and explain you problem.

Hope that helps.

I'm sorry I'm new to this forum, but I have to ask, is this automated template reply? I don't know if bots are allowed in this for forum.

1) I already mentioned that it's a laptop, so no other SATA connector.
2) My question is this normal/to-be-expected or not? I ready somewhere that the SSD needs time to recover after writing, but is that what's happening here?
3) Assuming I do try the SSD in another computer, what would I gain/find out?

Welcome to the community then.
No, it's not an automated reply. If you have an optical drive, it's also connected with a SATA cable. I don't think that it's normal to get that low readings on the transfer speed. If you test it with a different computer, you'll be able to isolate the problem. If the SSD still keeps acting up, then it might be a faulty SSD, if it works fine then it's probably something with your system (OS related issues, firmware, SATA cable etc.). That's why I recommended that.

ok thanks

ok, problem solved, I reached out to Crucial customer support, they advised me to change the SATA driver from Intel to the generic Microsoft one, I did that and it worked! copy rates are constant and very high now! Thanks anyway though

I can't believe intel's driver actually did that :/
