And JJRambo was right for Superfetch etc

Watch this part:

?Windows 7 tends to perform well on today?s SSDs, in part, because we made many engineering changes to reduce the frequency of writes and flushes. This benefits traditional HDDs as well, but is particularly helpful on today?s SSDs,? wrote Michael Fortin, one of Microsoft's Distinguished Engineers, in the Engineering Windows 7 blog.

When a solid state drive is present, Windows 7 will disable disk defragmentation, Superfetch, ReadyBoost, as well as boot and application launch prefetching.

?These technologies were all designed to improve performance on traditional HDDs, where random read performance could easily be a major bottleneck,? explained Fortin.

As i said few years ago when Vista was released Superfetch, Readyboost is useless and it will dissapear as hardware actually HDDs get faster. Superfetch, Readyboost was software solution Microsoft has to overcome poor Windows File System Performance or better say File/Folder structure and natures of standard HDDs itself. I got attacked by a lot of people including Mr. Brandon himself. Oh well, i knew time will show that i was right.

You're not very good at reading are you ?

They're not removign superfecth and readyboost, They are improving on it. Things can ALWAYS be improved. It was never flawed to start with. but now it's better.

SSD's don't make superfetch obsolete, in fact they make superfetch even better at, or rather SSD's make superfetch even better.

So no JJRAMBO was not right.

And stop inflating your ego. You're "opinions" keep falling short of the facts, even as you now proved.

And btw, the major reason for disabling superfetch on SSD's has nothing to do with performance, but the lifetime of the disk itself, as SSD's have a limited amount of rewrites. It's high, but still limited. So it's a balance, you get improved performance with it on, but not as much as with traditional drives, but at the same time you reduce the disks lifetime.

Er... I'm sure I'm reading the quote correctly. It says those features are automatically disabled on devices with SSD's because they're not needed. So they won't be removing SuperFetch etc for traditional HDD's, but they will certainly be disabling the features..

So I think you need to re-read the article youself before you go on your little self-righteous rampage!

Just a thought but, maybe they disabled Superfetch on a SSD to preserve the lifetime of the drive?

SSD's are fast, but their throughput (~3 Gb/s due to S-ATA) is still nowhere near the Multi GiB/s bandwidth of RAM.

From your profile you weren't even a member here when Vista was released.

...Superfetch, Readyboost is useless and it will dissapear as hardware actually HDDs get faster. Superfetch, Readyboost was software solution Microsoft has to overcome poor Windows File System Performance or better say File/Folder structure and natures of standard HDDs itself....

You seem to be mixing up different types of drives. The article is clearly referring to SSDs:

"When a solid state drive is present, Windows 7 will disable disk defragmentation, Superfetch, ReadyBoost, as well as boot and application launch prefetching."

And you are talking about HDDs. Superfetch, ReadyBoost, etc. are still activated when you use a HDD which makes sense as these drives are still too slow.

I agree with Athernar. They will be doing this to preserve the lifetime of SSDs, not because it is no longer necessary.

Too bad you're still wrong. You even quoted the reason why Superfetch and ReadyBoost was designed, but you failed at comprehension. You should to read before making a fool of yourself.

One of his accounts? You're allowed one, and if you screw it up, that's it. jjrambo has been around the whole time through the Vista release. I know, I've argued with him. :)

Modern HDDS have a higher density and faster transfers than older drives...

But latency hasnt changed in ALONG time...

Thus Readyboost/Superfetch will still help.. and claiming it was to overcome poor file system performance is just a bunch of crap and no it isnt the File/Folder structure..

Its to do with the mechanical functioning of a HDD and the fact it takes time to seek data from a location whereas RAM does not..

Its impossible to believe that someone who knows jack .... about what they are talking about can have an ego so big and try to flaunt it.

I was saying that in a general term, maybe he had another account, maybe that other account got banned, so maybe he opened a new account...it happenes on every type of forum on the net!

Oh, look at the little kid with the snappy comeback...NOT -- however the 'little kid' comment is right on the mark; and cutting & pasting is not against the rules on neowin so please go sit in the corner and don't move until you learn to respect your elders!

i dont understand what the big deal about his comment was.. he was just mentioning since it shows jjrambo joined in feb 08. if anything he was thinking before he spoke, no?

ReadyBoost is a feature that will probably be pulled out in the long run. Superfetch will remain for a long time, why? Because it's a good feature, and until SSD's become faster, cheaper and bigger, this will always become to case. As stated above, hard drives are getting faster and faster, but there will be a limit to what it can produce because of it's seek and speed problems. It's going to get harder and harder for hard drives to be come faster and faster in the long run, only SSD has a solution for them.

Superfetch is disabled to preserve the life of the SSD drive, not because it's a useless feature.

This part here confuses me. Not only is this misinformation, but I don't see how you got this conclusion from the article. If Brandon argued with you because of THIS, you definitely deserved it.

Why is it misinformation? Vista/W7 file performance is still very weak compared to XP. I actually just demonstrated that here at work about half an hour ago.

Two 1.8 C2D machines, same HDD. Mine running XP and the other one with a fleshly installed W7. ~16000 code files inside a zip file. Using WinRar, mine took 14s to decompress while the other machine took more than 40s.

All the caching W7 does kind of makes this problem go away, but when you need pure file I/O performance it just doesn't cut it.

Take this test I did as you will, but it certainly leaves something to think about.

Well what version of WinRAR did you use?

Perhaps WinRAR needs to be updated??

Theres now a beta of WinRAR 3.9 that has FINALLY been ported to x64 that wasnt there a couple months ago last time I checked for an update..

Perhaps there are some new things to take advantage of in Win 7 that it just hasnt been updated to accomodate yet?

I agree. Disabling is not improving :laugh:

Superfetch has nothing to do with the life of the SSD drives.

The W7 machine had the latest beta (these machines were both running in 32 bit) of WinRar, mine had an older version. This "problem" has existed since Vista. Before SP1 things were much worse, to the point of being frustrating.

Like I said, as long as Windows is able to cache most frequent files, this is a non-issue. When you have low amounts of RAM or are reading/writing many uncached files (like I did) things are much slower than previous Windows versions.

Depending on your daily workflow this might matter or not.

@Ricardo Gil - Going from your comments, did you also notice a performance drop in searching the storage medium w. 7/Vista compared to XP?

So why exactly does Win7 disable such technologies when an adequate SSD is used? I think they are beneficial technologies so why the hell would they disable them (especially Superfetch) on SSDs? What exactly do random write and flush performance of the disk have to do with it? As noted, SSD's are still an order of magnitude slower than RAM.

If the system disk is an SSD, and the SSD performs adequately on random reads and doesn?t have glaring performance issues with random writes or flushesi>, then Superfetch, boot prefetching, application launch prefetching, ReadyBoost and ReadDrive will all be disabled.

Per the supposedly 'slower' file access in Vista/7, that seems silly to me. The only way I can reconcile such statements is the possibility that the new 'low I/O' costs a minute amount of overall speed for generally much better responsiveness when performing multiple file operations. (Notice that accessing slow CD media or doing a large file transfer no longer renders the entire system sluggish and choppy as in previous iterations of Windows - still not great but noticeably better)
