15'' rMBP (Early 2013) SSD extremely slow?

[maxmaut]

So I've been using my macbook for 2 years (bought used) and got used to the speed that it operates with. I'm a designer, using Adobe apps, working with large files all the time, I've got used to the fact that there is a little lag all the time when I'm moving around artboard, etc.

But I got to use my friend's mac with exactly same setup and saw that there is no lag at all, even with much bigger files with much more layers/objects/etc.

So I ran the SSD test tool from Blackmagic and my speeds are nothing close to what I see on youtube videos. Read is around 110 mbps, write goes to 400 sometimes. This is not normal, is it?

Screenshots of "about this mac" and speed test app:

What do I do about this? Any fix? Any more advanced tests?

Make sure trim is enabled in your system report, if it's not it could cause this it should be enabled by default unless it has an after market SSD then you'll have to use a hack or trim enabler to get it to work.

Your model has a SATA 3 connection so it will max out at 550mb/s read and write it will never reach the speeds of the PCIe ssd's found in the more modern retina macbooks the current ones run at nearly 2gb/s.

Of course it could just be dying (although if it is you are lucky they often die with no warning) so make sure you have a current back up of your system and replace the SSD if needed.

You only have about 40Gb free on your SSD (around 5%). I'd say that's probably the culprit.

SSDs (the OS too) need free space to maintain consistent performance.
If you look at the Anandtech's SSD benchmarks (http://www.anandtech.com/show/6489/playing-with-op)
you'll see—though that was back in 2012; things may have changed since then:
"Whatever drive you end up buying, plan on using only about 75% of its capacity if you want a good balance between performance consistency and capacity."

You should try freeing up as much space as you can by moving stuff you don't need off to an external disk.
Looking at your disk screenshot, you have 346Gb of Other and 214Gb of Movies on your disk. That's a good place to start.
Also, make sure you empty your Trash after you've moved stuff there. Don't just leave it in the trash; it's all still on your disk.

Of course, as Samuelsan2001 suggested, it could actually be dying.
Keep in mind that you can't replace the SSD though. Those new MacBooks come with all parts (RAM included) soldered to the board.

I hope that helps.
Good luck!

Officially you can't replace it without voiding the warranty. However, the SSD itself is not soldered on. A replacement does however cost an arm and a leg on eBay.

Somehow it got back to normal. 420 read speed, write speed slightly lower. I don't know what happened and how to explain that.
