Desktop is faster using ssd, and I used velociraptor, and I aint talking about the number of data beeing read from the disks, but the snappy obviously felt sensation using ssd.Quote:

For me ssd made an impact as much I wouldnt go back to drives with old tech.
I can redo those tests on my raptor if you want... I've done some already; it takes ~2x longer to load games, the copy/paste tests are 4-5x slower. I don't know how I can get more real world than that :shrug:.Quote:

Editing HTML code in DreamWeaver?????????
I can do that with 4 DivX and WInRAR instances in the background LOL.
@Speederlander, note that you have Mtron SSDs, which even their fastest 7500 Pro line aren't really the fatest kind today... I doubt you'd have the same feeling even with X25-M, much less -E.
What I will love the most with SSDs is no need for cooling! That's not just less heat and noise, that's less dust in the room! (or ionized particles, whatever :D)
I guess you're missing some parts here.Quote:

Does your system feel snappy ? Is it responsive and fast ?
How long does it take to alt tab for example from DreamWeaver to a working ( in progress ) PhotoShop window ?
What kind of difference does a good SLC SSD do in this scenario ? ;)
Try the same with a single WinRAR instance extracting the data from an archive... ( yeah, it's getting worse :D )
I run a pair of the 7500 pros in RAID 0, soon to just break them up and use each for a VM. Those should be perfectly speedy to "feel" a major change. And that's my point, do you feel a slight improvement with SSDs? Yeah, sure. Is the vast benchmark improvement reflective of how they feel compared to the fastest (SAS and velociraptor) platter drives? No. At a certain point, when something gets fast enough, a lot of the improvement becomes undetectable.Quote:

well youve obviously gone crazy. give me rejected ocz ssd so i dont have to listen to the raptors clicking.
Alt-tabbing is instant, the disk plays no role in this, unless you are so low on RAM that you get swapping to the drive (I have swap file turned off).Quote:

Is it responsive? Hell with 200% CPU usage, what do you expect? The disk is not a player in this case, trust me.
None:Quote:

unless you're talking of Fusion IoDrive or X25-E only. From the page above, X25-M and non-X25-E SLC SSDs are slower than VRaptor during multitasking.
See link above. Mtron's are in the Samsung/OCZ SLC range, the X25-E would change the picture.Quote:

I'm running 2x64gb ssd's v.2 jmicron controller on a 5805 and happier than a pig in #$&*, replaced 3x 150ADFD raptors raid5
I heard Apex series 120gb nand is quicker than smaller config, not sure if this will apply to Vertex...............
That remains to be seen.Quote:

I'm willing to bet that the system will be way more responsive with the SSD.
WHICH SSd?:)That is the question.. not the Mtrons or alike.
Even a single Mtron 3500 series is going to make a difference.Quote:

with all this testing I hope you guys aligned the partitions or you wasted your time.
vertex is an IO monster BTW but remember this is mainly cache induced, linear reads writes are not much better than Apex.
SSD testing needs a total revamp, none of the common HDD tests tell the truth OR give an end user any idea about whether a cheap drive will work ok on their system or they need a more expensive drive.
Here is a question for ya'll
What is the minimum IOP's you need 4K random write 10GB test file for 2 mins for a drive to work without causing the sata controller to pause and cause a stutter?
Not 1 review on a forum or a website yet has proven what is needed and what is not...lets see if you guys can actually come up with the answer ;)
I did a sector to sector copy when moving between drive setups so everything was EXACTLY the same.Quote:

I know my X25-Es are well beyond the helpful IOPS number.
Exactly. This will get most SSDs... regardless of cache. I have a 13GB backup folder which I copy between multiple machines weekly at home.Quote:

My Velociraptors would chew this thing up without thinking about it. Amazing write speed - as fast as my other WD6400AAKS could send it. When I went to copy this huge folder onto my new Titan SSD RAID0 array, it actually handled it amazingly well, but I did experience quite a few half-second pauses while writing. I use robocopy which shows me EXACTLY where the SSDs slow down during the write process. It's always when it gets to a folder with a ton of tiny little .jpeg's or similar.
The folder typically took just about 3 minutes to write to my 3 Velociraptors and it took about 4 1/2 minutes to write to the 2 Titans. Not bad, but clearly slower. There comes a point where, depending on what types of files are being written and how much of them, where cache or no cache doesn't matter. Cache gets saturated when the write requests keep coming after many seconds and certainly minutes. It fills up and then still has to wait on the SSD(s) to write it all. Now day to day multitasking? Yeah, cache is the answer.
Now I rarely ever write that folder to the SSDs - only during a system rebuild. It is always READ from the SSDs which is ridiculously fast (faster than my VR's could ever dream) for LAN backups.
thank you for bringing more common sense to the subforum.. it has gone randomly/ioply mad :DQuote:

not to hijack this thread, but how long does formatting to ntfs take on a ssd?
raid0 4x ssd @ 64GB takes less than 2 sec to normal format @ winxp install
I hope all this what bencmark is really important for whom stuff will get cleared up this year, cause Iget the feeling people are getting bored with looking at silly HDtach screens...
:)
Can you define a "stutter". How do you measure it? Is it a subjective experience for the user or can you objectively measure it? Would that "threshold value" be different for different users?Quote:

But there I don't think there is necessarily a linear relationship between IOPS and "stutter". I don't think you can say "at this IOPS, you get stutter" . For example you can use a regular HD, and have very low 4K random write IOPS, but it's not the same perceptible experience as "stutter" on a SSD.
I think best tests are the ones that test real usage patterns/conditions
One_Hertz
After reading your test results, it seems that it is better to go with the on-board RAID controller over a hardware RAID card?
As for heat, I have seem reports that the SSD's get just as hot as a regular HDD.
For certain purposes...yes. Overall... no.Quote:

Your actually thinking that highly of review sites and reviewers?Quote:

Even a prominent site as benchmark review havent got to a good benchmark yet. And those guys should know the in and outs of harddrives.
just smack 1gb cache on your ssdīs and they run just fine.
1gb ram nowadays isnt that much in cost.
Much easier solution instead of using limited controllers.
Who ever made that decision to use jmicron should be shot.
It was a bad business decison.
IMO.
Since ssd are getting raided in all sorts of ways, we will see as your own tech simulation shows, a speed increase where its a must to get raided cards as sata 2 and then sata 3 is not enough for millions of users.
The train is about to leave the station and what do we get? sata 3 which is to slow for us.
If someone would be smart out there, they be doing such solution, providing ssd with pci-e out of the box.
ah yes, called fusion io drive.
The standards is to slow to adopt to the market.
SSD will simply explode this year and next, and what do people say when simply, this drive isnt any good to buy (vertex 2) since its limited by my motherboard?
Ah well, I get a raid card then ;)
