Windows 7: Think you know SSDs? Think again.

Windows 7 x64 Ultimate

As long as you don't need that extra HD space for something (like dumping raw images in the field) then yeah, it'll be a total win. I did the same thing to my relatively new VAIO. Laptops these days are chained down by the spinners in them. an SSD really lets it fly like it was meant to.

Before you begin though, go to sony's website and DL every single driver for that model laptop and burn them all onto a CD. There could be like 30 installers all told. But then after you have installed a fresh windows 7 on the SSD in the laptop, you can then get back proper functionality for the card reader, wifi, bluetooth, trackpad, special function keys, proper battery management and on and on. (Assuming the laptop CAME with windows 7)

I have 100% original shipping functionality with a clean install of W7 doing that (minus certain sony blaotware apps I "forgot" to install)

Windows 7 SP1 Ultimate x64

Hello ignatzatsonic !
Yea of course, I was planing to put only OS and the applications on SSD and the rest of my personal data (everything) on HDD, but SILL is it really worth to replace 500 GB with 80 GB (from the available Memory point of view), I mean I am using my personal data every day!!
And one more question pleas, in case I use my HDD as an external device! how big is the risk of HDD failure when I use it externally and internally ..??
Thank you very much for responding )

Does the VAI) have a usb 2.0 or USB 3.0 ports?

If USB 2.0, accessing the external daily is going to be a tad slow dpending on data accessed. If USB 3.0 + a USB 3.0 external, SSD all the way.

Depending on external drive model, the failure rate is not dissimilar to a standard internal HDD. The weakest points on externals are the USB connections (easy to knock repeatedly) and same goes for the power plug.

But overall, you'd notice an appreciable 'snappiness' improvement swapping the 5400 drive to a SSD as mentioned by ignatzatsonic

Windows 7 SP1 Ultimate x64

Hello smarteyeball.
I am sorry to ask but what is VAI ? If you mean External Hard Drive "Enclosure" then yes I am planing to get with USB 3 support. My HDD is: TOSHIBA MK5055GSX 500GB 5400 RPM 8MB Cache 2.5" (hope it's compatible with USB 3 enclosure?!)
And according to my HDD model pleas tell me if it is ok to use it as external? Also you mentioned the USB is the weak point of external heard drives! I do have a eSATA port on my laptop, so maybe it's worth to get the HDD enclosure with eSATA support as well?
Thanks for your advice's ))
Have a nice day

Question; Prior to SSD's it was pretty much a rule of thumb that when your HHD was around 75% of its capacity that you should get a larger drive so as not to sacrifice speed, etc. Does this hold true for SSD's or not? Does it make any difference at all?

I don't know about that 75% number, maybe that came from the fact that the data transfer rate on HDs drops significantly the closer to the inner spindle you get (as you fill the drive).

But certainly if you are reaching 90-95% you are limiting the number of places that new data can be efficiently written on a spinner and agressive defragmenting may be needed to keep the drive from having terrible write performance.

Neither of those really affect an SSD. It can write anywhere with the same exact speed, and it can read and write files that are "fragmented" just as fast as not. In fact the term "fragmentation" doesn't really even apply. Files are writen into 4k blocks (Just like on a HD) and so are "fragmented" at the start, but those blocks can be anywhere and it doesn't make any difference to the read/write speed at all.

That being said, there was an issue in earlier SSDs that indeed did slow them down as they started to get full, but these days, idle time garbage collection and "TRIM" support fro mthe OS makes sure that there are always fresh cells ready to go when the time is needed to write new data. So todays crop of drives really don;t suffer from that problem at all any more.

(Note that TRIM support on Linux is a bit spotty as well as non existent before Windows 7)

True, but over time SSDs usuallly are compacting data for faster write speeds. 95% may be ok, bu not if you're booting off of it.

I'm still trying to find out whether cleaning Free Space on a ssd is good or bad to do.

It's good only ONLY if using a tool from the dive manufacturer to do so and that is only ncessary if it's an older drive (like 1.5 - 2 years old or older?) and/or if the drive or your OS does not support TRIM.

Otherwise it is not only unnecessary but potentially (though only slightly) harmful.

Choose between 2 new SSDs.
I just bought a new HP Envy 4t. I'm looking for a thin 7mm SSD to put in it, and I've narrowed my choices down to 2. I understand one comes with a data transfer kit and one doesn't, and there's a slight difference in capacity. That being said, and "stated drive performance...

Prefetch and SSDs
My understanding from reading the MSDN blog was that prefetch and defrag were to be disabled for SSDs with "good performance." I have a second generation Intel X25-M 80GB as my boot drive which I believe qualifies as a "good performing" SSD. I do see that defrag is disabled for my SSD (C:...
