How can I improve my SSD performance?

Here is my run in the attachment. Can someone please tell me how I can tune it to be better?

 

Well you can do this tweak:

Also, if you use ThrottleStop, uncheck the C1E box. If you don't have it, get it here:
Downloads | Tech|Inferno

Run it, make sure you hit "Turn On" and uncheck C1E. Your 4k write speeds may increase 50-100%.

 

By the way, the R2 SATA 2, so unless you do RAID 0 like I did with my 320 series 160GB, you won't get that much higher. Also your Vertex 3 is rated for much higher speeds if you have SATA 3. If you only have a SATA 2 laptop, your speeds will be MUCH lower, which your scores look like a typical SandForce SATA 2 score. Your 4k scores are a little low, there are some registry tweaks you can perform.

 

Also there is a program called fancycache that greatly increases ssd performance by caching with your ram, google it here are the scores from my single corsair performance pro running at sata2 speeds

 

Wow this actually works!! Just using throttle stop alone have improved it a little, now I will go for the reg edit thingy but I will add to it the 5% OC from the BIOS menu, lets see what this baby can do

 

kalisto, over 3000 megabytes/s (MB/s) write on a SATA2 connection? that's impossible.

SATA2 on your computer maxes out @ 3mbits/s which is 375 megabytes/second.

You are reporting 10x higher than is possible on a single sata2 connection

So, i have a feeling that fancycache is doing a lot of fancy stuff to your numbers

 

those numbers better be real!!!

 

nope, not physically possible on a SATA2/3 connection...but it does look impressive though

 

lol check what I did come up with.....I think if it really uses RAM for reading yeah maybe it can work that fast but the writing here looks about right on the money or so..

Now I got the 5%OC on, I need to do the reg and run the test, I'm sleepy now so I better do it when I wake up

 

Yes, it is possible. Take a look at the post at the bottom of my sig. It uses extra RAM to enable a cache that speeds up even SSD's.

 

yep using the same thing to boost my mech drive, it used a ram cache to hybrid your drive

 

Well, I just got done testing it out a bit more. On GTA 4, it is honestly hard to tell if it helped or not. Everything loads smooth as it is, so I really didn't notice any different. I did however notice it on things like RAGE and Team Fortress 2. Assets like textures or levels that get loaded and then purged from regular RAM and then have to be reloaded later were virtually instant.

Of course, I did have it using 8072 (half my RAM) for the cache. I also enabled delayed write and kept it at 10 seconds. Anything that had to write data while I was still gaming (like GTA 4 autosave) did not even cause the small stutter that I was used to.

Programs from within Windows, like Firefox, outlook, powerpoint, etc; were truly instant reopen. This would come in handy for anyone who opens multiple instances of Excel or Powerpoint and the filesizes are pretty big.

I will continue to test and report back, but to be honest only some people will find this useful. The data must be loaded first and then purged from normal managed memory for this to be effective. I can think of a few other reasons that this will be beneficial but its not the miracle that some people are hoping for.

Here is my original thread on my find:

Will it improve your SSD performance? There is a definite possibility depending on what you use your system for. If nothing else, it is an excuse to go out and buy more RAM for another system that is slower and is used for business use and has a mechanical drive.

 

Hmmm I have 16GB RAM so I should try out fancy cache. Who knows. Does it actually seem to help? How exactly does it work? I know it caches to ram but I'm sure it has to do that with each start up. Won't affect boot time though. And its reading from ram, not the sad so those numbers don't reflect sad speed.

WoW!!!! That DID help a big time with the reg edit, I put in 97%, let me try it next time on 100%
The 4k read and write times are WAY higher than before, this is cool
Thanks guys, gonna rep you.

 

This is with 100%. 4k QD32 writes dropped way down though, dunno why

 

I use 99%

 

No, its not real SSD speed of course. It is just using the RAM you designate as an additional cache. The items that normally are purged when you close them or when the program specifies it no longer needs X resource, is kept in the cache.

I read quite a lot about it and I am very happy with the additional speed that this program offers as well as how it can help with both HDD's. I put my SSD at 2048 and my mechanical at 8072 and I am completely impressed.

Its not going to help for booting or for loading, but it really helps for keeping things that get reloaded often.

 

fancycache is simply a ram drive, correct? So when the computer goes off, data on the ram drive is lost? or do they keep the state alive via some other means?

 

I'm pretty sure nothing gets stored.

 

No fancycache is not the same as a ramdisk. What it does is that it uses it like a cache like the Seagate Momentus does with its nand cache. Everything drive based will be written to the ram and back to the drive occasionally. So for example, if you are word processing and you hit save and you save to a folder on your C drive, it actually writes it to your ram first. And it will load it to your disk when it deems necessary. Not good if you have a sudden crash or power outage as your current work cache gets lost immediately.

 

widezu is right, with one minor difference. Whether as intended or unintended, if you are simply loading resources over and over, this dramatically speeds it up. Games are subjective as anything that loads more resources than it reserves for RAM (most 32 bit games) this acts as an intermediary. Instead of the resource being purged from RAM and having to be reloaded from disk (slow) it is pulled from this cache; provided that the cache has been given enough space to store all the data needed.

Team Fortress 2 is a prime example. If you play 4-5 maps, the maps themselves are not excessively large but the program purges them each time another is loaded. With a cache size set at 8072, the moment my 4th map is loaded into memory, the next one (map number 1) is still there as well. When the game moves to that map again, its load is as close to instantaneous as I have ever seen. I literally am the first one in the game if my lag is <100ms to the server.

I would imagine you would see improvements on Call of Duty and Battlefield 3 as well, if you gave them enough RAM to use as a cache. RAGE is actually the most hilarious difference I have seen. I get the texture pop when I first start the game and then it ceases to happen until I have to restart my PC. My friend who has a damn nice desktop rig started using this when he saw the difference it made just in general use.

You do NOT have to enable the delayed write. If you want to just benefit from the faster reading, you can. There are a great deal of options available and I encourage you to read up on them before testing them out. Some sound as if they would not be too useful to me (enabling level 2 cache) but not sure yet.

Anyway, hope the find has helped some people. I know it is situational for me, but it will be a buy when it goes full release.

 

The chief is mucking around with FancyCache lol!

Cheers.

 

LOL! Those numbers are sick! I know they aren't real but its hilarious to see nevertheless.

So how are you liking it Reborn? I am going to do some testing tomorrow to see if it affects VM's in VirtualBox. If so, would love to see Windows XP load in under 5 seconds because the entire VM is cached into memory.

Anyone else been messing with it? Even in Read-Only mode, its still pretty useful.

 

I Have been messing with it, its a pretty nice app, There is noticible gains, But I have also noticed some slowdowns with it too, particularly when installing large programs, but it could just be processor bottleneck, since i just have a dual core in here right now.

 

I played with fancycache also...both the disk and volume editions. I did seperate tests with both on my Crucial M4. Left fancycache on default settings with both versions

What was funny for me...my reads were off the charts...however, my writes were all down...my 4k writes were waaaay down with fancycache for some reason

 

Hmm. Wonder why that is? It did not hurt my write speeds on the M4 128GB. They are just as insane as the read speeds. Maybe our cache settings are different? Did you run a chkdsk to confirm your cluster (block) size and set FancyCache to the same size? My SSD and HDD cluster size is 4K.

It produces crazy read speeds and slightly improved write speeds on my Momentus data HDD as well.

 

Slickdude,

Did you not enable the write-behind checkbox? If you do not but you have Fancycache set to Read/Write, I would guess that this is the reason for your odd performance.

If you do not want to run the risk of corrupting any data due to a crash, it seems best to me to set Fancycache to Read-Only mode. You still get the incredible read speeds but writes are unaffected.

 

There were some discussion in some foreign language forums(chinese). Some say it absolutely does nothing but bench numbers,some say it help lessen write stress. (most of this is in realm of desktop)

I had try it on my SSD and I come to believe it doesnt do much and only lead to trouble. Now, i only use it as a delay write(2gb-3gb) for my torrent HDD.So I gonna present people's argument against it first.

1.Superfetch : windows 7 is actively caching stuff on ram
2. stuff must be cached first for the read speed to work but you have no clue what is cached(same as superfetch). The performance monitor show you nothing specific. Where a ramdisk + junction point let you control .
3.SSD is "fast enough".
3.Write cache : dangerous especially if you use delay write and it is OS drive. and performance impact is non-existent as SSD access time/write speed is high enough. no input source will require RAM write speed.
4.Write endurance is never a problem anyways.
Pro:
1.with high delay write, technically nothing is written on the disk during a session, SSD or HDD. One guy put a example where he download a few GB of movie ,(which is impossible to fit in a ramdisk),watch it, del it. using fancycache, he decrease access on the disk.
2. More flexible than ramdisk, for huge torrent task or download.
3. Performance monitor usually say cache read hit rate above 90% after few hour of use. (meaning it cache the correct stuff)
4. bench numbers

 

Here is how my new RAID0 SSD setup is performing.


With FancyCache... results are very similar to single SSD (small improvement)

 

What a hoot. FancyCache. The 4K writes are killing me.

​

 

This seems like an iffy program. Number seem insane and I'm not sure if I want to put unknown stress on my system. I treat my baby like a baby and not put some "special formula" in it.

 

Is this going to work for M4 SSD as well?

 

Yep works on all SSDs. Remember those aren't SSD tweaks but more Windows installation/CPU tweaks so aren't SSD exclusive.

 

Setting the cluster size to 16k seems to work best for me as well. (Windows default is 4k.) If you have SSD in RAID0, set the stripe to 16k to match.
