[SOLVED] Slow M2 SSD, only 30MB/sec!

Hello,
I had this problem in the latest Linux Mint 19, now I've totally re-installed to MX 18.1, and the problem is still there.

Here's my hardware:

The drive "PASSED".

But now look at how slow it is with an "sudo hdparm -t /dev/sda":

Code: Select all

/dev/sda:
 Timing buffered disk reads:  94 MB in  3.04 seconds =  30.93 MB/sec
That M2 drive should go at least 90MB/sec in a very worst case scenario (~500MB/sec in best case scenario), see here:
https://www.amazon.com/Crucial-Micron-1 ... B01K1JP32O
...where some CrystalDiskMark charts were posted.

Can anyone suggest what I should do to crank up the speed? Is my drive a dud or something? I haven't had this laptop even for one year. This is the original M2 drive that came with it from Amazon. :confused:

Sorry can't help with your speed issue that drive should move a lot faster than 90ms.
If you get the same speed on two different systems then maybe look at your bios settings ?
Is the drive new if so try reseating the drive test it on another computer
not new (9 Power_On_Hours 0x0032 100 100 000 Old_age Always - 539hrs)

Have a thorough read through this first:

https://en.wikipedia.org/wiki/Solid-state_drive

It'll give you the basic idea on where the problems could be since, almost every mentioned component has very much to do with ssd speed.

Then check a couple of forum posts like the one here:

https://www.gamespot.com/forums/pc-mac- ... -29216957/

When you are sure you really understood all of it, you'll probably understand where the problem is.

The speed of an SSD is depending on too many things to give you a short answer. It can be virtually everything and anything, starting with the cell's technology and current wear level and the controller, over the file system used, all over to some kernel patch that can reduce the speed up to 30% on it's own. Or -- it's just a simple thing of executing a trim command that can give you your speed back. There are hundreds of possible reasons.

I found a review of your SSD here:

https://www.nikktech.com/main/articles/ ... l=&start=8

If you are talking about 4K read, then your result seems to be ok.

Last, but not least: Amazon is renown for selling false products (maybe not knowingly) from time to time ... like this processor here and right now:

Definitely hampered by something...It may be a problem with the sync between the SSD's implementation of SATA and the laptop's SATA controller...

From a review...which indicates that the SATA 3 speed on that motherboard is sub par (but not as slow as your experience)
https://www.laptopmag.com/reviews/lapto ... ok-ux330ua
The 256GB SATA 3 M.2 SSD in the ZenBook UX330UA duplicated a DVD's worth of multimedia files in 28 seconds, for a ho-hum rate of 181.76 megabytes per second. That's slower than the 219.3MBps category average, the 508-MBps rate from the XPS 13's 256GB SSD and the 318.08 MBps speed from the Yoga 720's 256GB NVMe M.2 PCIe SSD. The 256GB SSD in the previous ZenBook UX330UA posted a slower 159 MBps.

I want to thank you all for your prompt replies.

I've found the solution, look at my hdparm now:

Code: Select all

/dev/sda:
 Timing buffered disk reads: 1298 MB in  3.00 seconds = 432.19 MB/sec
The fix was here.

It was a firmware upgrade, which my M2 drive needed. I had to use the firmware-upgrading CLI utility that Micron publishes. I can't believe the drive would just go slower and slower and slower, until you figure out to do that. It's not like it has a wind-up spring inside of it! :rolleyes:

Welcome to MX!

You probably are seeing some video glitches when scrolling pages in Firefox with your Intel graphics. We've found that you should be able to get rid of those by using MX Tweak/Other Options to switch to the "intel" driver and rebooting. Another advantage of the intel driver is that you can then set up va-api for hardware video decoding playback in VLC, qmplay2, and maybe mpv, and hardware encoding using handbrake from the test repo.

Thanks for the tip about Intel Graphics, @Stevo, I'll install that tweak. Thanks for the welcomes, everyone. :happy:

With the Intel driver activated my laptop feels BLAZINGLY fast. It's like the Looney Tunes Road Runner now. MX is the fastest-feeling distro I've ever tried (and it has way more conveniences than stock Debian).

Again, Thanks, @Stevo.
