8

I'm using a Samsung 700T tablet/convertible (basicallly, the Samsung equivalent of the Microsoft Surface Pro.) It runs Windows 8.1 This comes with a dual-core ULV CPU, 4 GB of RAM (which is too little!) and 128 GB SSD.

This computer occasionally gets very sluggish, pausing for 10-30 seconds before responding to clicks. It feels as if the computer is paging in memory, but I'm not quite out (3.1 GB utilization out of 3.9 GB) However, when this happens, performance monitor shows that average disk response time is in many-seconds.

With an SSD, how can that happen? I'm supposed to get 10000 ops/s through that interface, right? No heavy mechanics involved.

See this screen shot for what this is:

Task Manager showing performance graph and 9058ms response time for the C drive

The second question is: How can I fix this? (If at all.)

Your SSD seems to be used 100%, causing the high answer time and definitely also wearing it off. There has to be a process causing this, e.g. an antivirus solution meaning it too well. Fastest way to determine what's wrong should be to simply look up which application it is. While the perfomance monitor Windows 8 delivers is pretty powerfull, you should really try ProcExplorer

Run it with elevated rights, right-click any column, select columns and view the I/O:

As soon as you know which application it is, come back and we'll try to find a way to stop this.

I had this happen on Windows 10. I uninstalled the Intel SATA controller in device manager (requiring a lot of patience, given the slow response).

Before rebooting, also open regedit and re-enable the storahci service (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci\StartOverride -- set to 0), otherwise your machine won't boot (INACCESSIBLE_BOOT_DEVICE). If you forget, you can start up in safe mode and do it

Open Computer Management (right-click on "This PC" and select "Manage", or type compmgmt.msc at a Run prompt) In the left pane, expand Xystem Tools | Event Viewer | Windows Logs | System. Look for "warning" or "error" messages with "Disk" as the Source. I'll bet you're getting a bunch.

btw, if your SSD is in any sort of hot-swap tray or caddy, get rid of that. IME, most of them are not what I'd call enterprise-grade hardware. A simple cable from the motherboard to the SSD (or HD for that matter).

The ope/s are best case scenario, so don't bank on 90000 in the q. That said... the picture looks like there's an issue with the SSD. The read/write levels are too low for that response time. I had a similar issue with an OCZ drive and an intel controller, where when the drive was sent to sleep it didn't properly wake up, or took a large number of seconds to wake up. The solution for me was to no longer put the hard drives to sleep, and it worked a charm on a pc that was always plugged in. Not sure how that will play out on a tablet though!

If it persistently stays at 100 percent, then your SSD is failing.

I once had a computer with a hard disk that did so. I removed the other HDDs, DVD drives, etc but I still had the same 100 percent problem. I then took it out of my computer and suddenly, disk usage was only 25 percent. I later realized that the case was not big enough to hold my 3.5 HDD and it was being squeezed. If this is your problem, get yourself a new case.

Also, make sure your SSD drive is perfectly horizontal
