yeah I think so, I have x2 120gb agility 3 on raid 0. Always had about 100-80gb left free space on them but it doesn't feel like they are as fast as they used to be.

CPU / motherboard? Is it a system that is capable of TRIM on RAID 0?

You're talking about slower writes, not slower reads, right? If it's slower writes, that can be from junk being in every block and needing to dig around / shift data on every write. Do you have a benchmark from prior and a benchmark result now to compare?

See here for some related info:

To be sure, if you really really wanted, you can do a secure erase of the drives to get a blank slate where every block can be written.

Will formatting ssds make them regain their performance?

You don't need to format it ever. Research how to get "TRIM" to work in Windows 7 or 8 if you don't have it working currently. My Samsung SSD came with software to do that TRIM stuff on old computers where Windows can't do it by itself. There might be similar software for whatever SSD you have. If you use Linux, you probably have to set up a schedule for running a tool that does it.

A typical SSD needs a good amount of free space on the drive for it to regain its normal speed through that TRIM stuff, something like 20%.

My specs: i5 2500k @ 3,4ghz, Z68 , x2 120gb agility 3. I think from a quick search it's capable of TRIM on RAID 0. I don't have a benchmark result from the past I am afraid. I am running windows 7 atm I ll look more into TRIM I guess, thanks for all the info guys.

Okay, then above is very relevant. For a long while, TRIM was not available in RAID 0. Then it was officially supported on 7 series mobos on Intel. You needed some kind of wrangling around to enable it on 6 series mobos like the one you have. See the above AnandTech link, as that becomes very relevant now.

I don't know if Intel opened up support later or not.

My router has QOS options (but all disabled by default), how long would it take to set up so this doesn't happen every time someone watches a 360p youtube video on the network? (knowing basically 0 about how they work) [image loading]

I don't really trust QoS options on consumer-grade networking gear. But more or less, you need to throttle some traffic so others get priority. As for implementation and options, it depends.

As for anything, nothing should behave that poorly from just watching YouTube. Even if it that takes all available upload or download. YouTube shouldn't be destroying the connection like that.

Hard reset the router and/or simply try a new one.

On any quality setting, it seems to wait, idle for a bunch of time.. and then download like the next 30 seconds of video in 3 seconds, and for that time period internet just drops everywhere else. On a 720p video it's like 2k ping and packet loss showing up for 5-10 seconds a couple times a minute

It kind-of did the same thing a little on old router, but there was no good connection aside from wired, now this one has decent wireless people from a few rooms away can pull 700kb/s and everything else deaths

Will need to deal with this at some point soon.. maybe need help because i'm completely lost. I guess this is a seperate issue :D

Continually amazed by uk internet. *turns router off and on again*

If the people sharing the net are, uh, friendly and amenable to such things, maybe you could try rate limiting on each person's computer so nobody can hog it all. (try NetLimiter or similar)

Or at least try it out to see what difference that makes.

The people on wireless can pull 700 kb/s and this is destroying everything? I hope you actually mean kilobytes and not kilobits. What's the connection rated for, and how much can you get on SpeedTest with nobody else on?

yea, KB. Forgot to capitalize. It's 8mbit down 1mb up, so in practice now, ~5.5mbit down, 0.6 up. Usually ~40 ping, 1ms jitter 0 packet loss. Kind of went to hell recently

As I often state, I've never met a consumer-grade router with QoS that wasn't terrible. As for difficulty? Not that involved. It varies by implementation and what you're trying to do.

For instance, my last QoS usage basically involved specifying a port (and maybe IP?) and saying "traffic through here gets high/normal/low" priority. You could sniff out port usage on things like XSplit via netstat. In your case you'd probably be setting traffic through 80/443 as low across all IPs and your gaming ports as high. But as I recall that was an unusual implementation. I'm not sure if there's a way to prioritize by domain to do something like throttle YouTube but not regular browsing. I'd really have to play with your router's QoS and see.

I had some success with my QoS, but it really doesn't cope with full usage load. Ideally with QoS you're pushing all the "high priority" traffic to the front of the line and making everything else "wait," but for whatever reason consumer QoS handles this very poorly.

Likely the only real success you're going to get is for users to be self-limiting their usage, especially when it comes to upload. Asymmetrical connections like to treat 1% of maximum upload speed as equivalent to 1% of maximum download speed. In your case, that means 1kb up = 8kb down. YMMV. I think TCP is supposed to have an overhead of like 10%?

Netlimiter works pretty well for specifying a rate cap across a computer's traffic, but it has to be installed and a limit set on each user's PC. It's not free, but it's pretty easy to find. The downside is you're probably going to end up either wasting bandwidth or having to lower each PC to a lower threshold than acceptable for normal usage (depending on how many devices you want to hook up and allow simultaneous usage); I don't think there's a way to set up a centralized, dynamic configuration.

Also your story of YouTube's loading in chunks sounds like DASH's doing, but I don't think DASH is enabled for 720p (only 1080p), so I'm not sure.

Isn't that how it behaves for everyone? It loads like 20% of the video and then stops completely and waits til you reach that point, sometimes stopping for like 3-10 seconds before starting to download more at max DL rate

Hey guys, can someone suggest me a motherboard to use?
I have an i5 2320 (locked at 3 ghz), 8gb ram, ati 6770.

I have spare parts lying around to make a 2nd pc, but missing a motherboard. I'm thinking of getting a new mobo (using an intel DH61WW atm) and using my old one with the 2nd pc.

From what I understand, the cheaper a motherboard is the less features it'll have (extra slots and whatnot), so since I can't OC and I don't need many slots, I should aim for one around 100 bucks right? Maybe like http://www.newegg.ca/Product/Product.aspx?Item=N82E16813157303

You are looking for H61, H67, B75, or H77 motherboards, preferably the latter 2 at around $50-$70. $100 for a H series board is relatively high-end.

Guys my hp brand laptop's screen recently cracked. While it is still usable, I would like to get it fixed. However to replace the screen I have to figure out how to remove the frame surrounding it first. I cannot seem to find the screws that hold it in place. Does anyone have any experience in replacing laptop screens when they cannot find what exactly is holding it on?
