SSD is really slow

[borislav1212]

So i recently bought an Acer Aspire E15 with an 250gb SSD on it. I started benchmarking the laptop and the results of the SSD where very good. Around 250-300 mb/s. But when i actually started copying files and stuff the speeds were something like 40kb/s. Is there something wrong with the SSD. Or is it supposed to be like that ?

If you were copying from a normal spinning drive that might be all it can give to the SSD. Spinning drives are slow. 40KB does seem super slow however, even for a spinning drive. How is everything attached? Where were coping from?

I was just copying a 100 mb file from my desktop to the C: drive and it was really slow. I don't know how it's attached the name of the drive is TS240GSSD220S

That's the SSD. What's the other drive? (desktop drive?)

 

[borislav1212]

What desktop drive ? I only have one drive- the ssd.

So you were copying from the SSD to the SSD? That does seem bad/slow. What's your motherboard? What SATA port are you using?

 

[borislav1212]

It's a laptop I don't know the motherboard. I found the SSD though it's a transcend SSD and it's SATA 3.

What laptop is it then?

 

[borislav1212]

acer aspire e5-576g-38y9 but the 1TB HDD is replaced with a 240 GB SSD.

Can't find anything on that model, but from a foreign site from what I could read it's a modern system. It should support that drive. Looking up the drive I see its not the fastest out there, but it should read/write better than 40KBps. Seeing as its in a laptop it could be a heat issue. Or perhaps there is a driver that needs to be installed. You should also try using Transcend's software to see what it says. I think this is the one you need.

40MB is better and less of a concern. Copying to/from the same drive is usually slower. My Samsung 470 can hit well above 200MB on a copy, but when I just tried copying to itself it settled in around 90MB. That's still double your drive, but I'm not sure how good your drive is. Can you copy to a different drive? Does it stay at 40MB? (Keep in mind if you try USB 2.0 that tops out at 40MB so don't try using an external drive over USB2.

I've realized that if I try to copy my steam folder it will go at 40MB/s but if I download a movie and copy that it goes all the way to 200MB/s. So know I know it depends on the files. I ran a couple of other tests and it turns out that if i'm copying a whole folder it's really slow but if I copy a single file of the same size its really fast.

I think this is the right one. What does this say?

Here are the results:https://pasteboard.co/H3c7tY0.png
(also i heard some really weird sounds from the laptop while running the benchmarks, sounded like a laser or something)

Your reads look good, your writes are a bit all over the place. You can look for an update for the firmware. Might help. But according to that things look good. You can hit 550MB on the reads, and the writes can hit just under 500MB.

Having to read/write small files will go slower than a single large file as you found out. That's why I suggested that program. I'd prefer the writes to be as constant as the reads are, but I'm not sure how to fix that. If you can update the firmware I would try that. But otherwise things look like I'd expect them to be.

I couldnt find any firmware updates. Anyway now I know that my SSD isn't as slow as i thought and I now consider this thread solved. Thanks for the replies!
