Very Slow Write Speeds (dedicated thread)

[Alexandra]

Talk of slow write speeds in the X98 Plus Tips / Tricks topic kinda took over the thread, so here is a dedicated place to continue that discussion.

It started with Mathias noticing that X98 Plus emmc write speeds were seemingly halved by the Nov 2015 Windows 10 update. Mathias’ numbers were about half of what Chris posted in his X98 Plus review. Another person suggested this was an issue before the Win10 update, but whenever it began, it seems widespread.

Attached are my benchmarks on a fully updated X98 Plus (Samsung CWBD3R emmc), and yes, most of those write speeds are bad. The issue extends to the sdcard as well; that’s actually up to 6x slower than it should be.

So far it seems we’re low on ideas for remedying this problem. Any thoughts?

Good idea with the new thread.

I also heard that the windows update made a big hit on the drive speed.

I experienced the same slow speed on internal disk (A5C6 Windows-only, Samsung CWBD3R disk).

Unfortunately I cannot say if speed where better before since I updated windows just 2 hours after receiving my tablet.

Same Samsung drive here.

It was not the Nov. OS update that caused this…I tried it before updating last time.

Two screenshots. The first time I ran the benchmark was the best, but still on the low side.

My Emmc values seems to be OK but SD-Card is very slowly if I compare it Chris review values. My tablet is  A5C8 with latest WIN drivers. Hynix Emmc and Samsung 32GB class 10 SD-Card. May it makes sense to create a compatibility list of SD-Cards in combination with X98 plus.

Kingston 16GB class4 works

Samsung 32GB class10 works

Trendscand Premium 300X class10 doesn’t work

64GB Patriot class 10 no go

64GB Silicon Power class 10 no go

32GB Verbatim class 4 OK

A5C8 version all Windows updates.

By the way, I wouldn’t call those speeds “very low”, just not up to the specifications of the 5.0 eMMC

I have the same drive as Chris has, Toshiba. Here are my results.
So it seems there are 3 different drives in these things now. Toshiba, Samsung, Hynix

Great speeds MadMax! awesome 4k write there

[Alexandra]

MadMax, wow, your Toshiba emmc scores are only slightly worse than Chris’ review emmc scores we’ve been using as a reference (attached for easy reference).

Could it be that the Toshiba emmc is simply superior to Samsung/Hynix (at least in the X98 Plus)?

And further, that some sdcards, like my Samsung Evo+ 128GB, just have poor X98 Plus compatibility resulting in (IMO) crippled write speeds?

I sent an email to Teclast aftersales support about the SD Card issue. They replied today. It looks their technicians are working on this issue!

Thanks Nicola, I also emailed Teclast aftersales on February 13th but have not got a reply yet. Good news that I can stop wasting time trying to come up with a solution like many other people, bad news we need to wait for Teclast. Is it OK with you if I post a link of your message from Teclast to another forum where this is being discussed ?

[Nicola]

Hi Neil, for me is ok.
