Re: W10 peek-a-boo for Junes update

Phew, Nigel, I had to read that three times to get my head around it.

I see what you are saying though and I will proceed to set up the other part of my 'C' drive (as perhaps 'Z' drive to avoid conflict with my other external drives/CD drive and Card Reader) and move my folders with caution but only when I feel happy that everything is settled down properly.

Thanks to your advice, I have downloaded the Samsung software for maintenance and updated the firmware, checked everything out and set it to 'rapid' mode.

I'm still confused, though, as to why this new SSD is still taking nearly twice as long to boot up (1min 4secs) against my old Kingston which booted at around 36secs. Could it be that Win 10 still has Win7 lurking in the background or could it be something else? I've used 'Advanced System Care' to make sure everything is ok the best I can and nothing else has changed since the upgrade to Win10. Puzzling indeed.

Many thanks again for your advice and instructions, it is much appreciated.


Keith

Re: W10 peek-a-boo for Junes update

Pleased to have been of help.

Make sure that the SSD interface is running at full speed. There are free apps you can use to check read and write speed which with the acceleration should be around 1,000 MB/Second.

However, the SATA interface can be a finicky one, and using the wrong cable can slow things down a lot. I found this when using a 'spare' cable from a DVD drive, which of course doesn't need such a fast connection.

I doubt that the presence of Windows 7 will slow things down as you won't be loading it, (it will just be sitting there) but one way in which recent versions of Windows (8 onwards) boost their boot times is to cache driver files in what is known as the 'Prefetch Cache' so that it doesn't have to look on the hard drive for them. It is possible that this is disabled for some reason which will slow down boot times noticeably.

You have a good copy of Windows 7 on your old drive so there is no reason why you shouldn't delete it from the new one. I would actually be tempted to reinstall your old drive, install W10 and use your new drive to store photographs or whatever.

Re: W10 peek-a-boo for Junes update

Again, thanks Nigel.

Before I started changing things with the Samsung maintenance tool, I ran their performance test (on the tool). The results were -

Sequential R/W - R-241, W-209
Random (IOPS) - R-7,324, W-20,751

After updating driver, ensuring everything was ok and enabling 'Rapid' mode, the results are -

Sequential R/W - R-2,601, W-2,635
Random (IOPS) - R-64,941, W-20,507

I think I managed to improve things there

The cables are the same as were used for my previous SSD.

I've also been finding boot problems via Google and sorted one or two apparent problems which I hope will help.

I'll again use Mr Google to find the 'Prefetch Cache' and check that out.

It is a thought to use the old SSD as the Windows drive but I've had that drive for getting on 4 years now and I'm unsure of the lifespan of the older SSD's.

Again, many thanks for your time and patience.


Keith

I have been using SSD's for four or five years and haven't worn one out, yet!

You can download an app for your old drive which should tell you the percentage of life remaining and will update the firmware if required. All of mine still show 100% remaining life.

To be honest with the low cost of 128 or even 256 GB SSD's you could invest in one just to use as a System drive. If you choose Samsung you can manage both with the same app.

If you go into the menu you will find an option called 'Overprovisioning' which basically sets aside 10% (you chose) of the space as 'spare' data cells and to cycle data around the SSD which improves both longevity and speed.

For bulk storage though you still cannot beat a spinning hard drive. Thanks to the competition from SSD's the current crop are both fast and cheap

Re: W10 peek-a-boo for Junes update

Many thanks again, Nigel.

I think I've got my head round it all now, thanks to you, and will make decisions on how I'm going to set things up before moving files etc..

I feel more capable of doing it all now thanks to your advice.

Re: W10 peek-a-boo for Junes update

Thanks to Nigel's help I have formatted the other half of my 1T drive, called it 'Z' Drive and moved my personal folders to it (not forgetting to change shortcuts I have). All is well.

Today, I checked everything ready to shrink 'C' drive (which has all the operating files) to around 250GB and expand 'Z' drive by the same amount. This is where I hit problems.

The numbers -

'This PC' states
C drive capacity - 446GB
C drive used space - 156GB
C drive free space - 289GB

Disk Management states
C drive capacity - 446GB

D/M 'Shrink Volume states
Total size before shrink - 457,013 Mb
Size of available shrink space - 55,306 Mb

That means that I can only shrink the drive by 55GB max.

I was hoping to shrink by something like 200GB which would leave approx 246GB available space for Windows/programs of which 156GB is already in use.

Hope that makes sense.

Help anybody?

In simple terms you can only shrink the volume down to the outermost segments. In the old days you would run Defrag to compact the data at the bottom end but you cannot do that with an SSD. (Furthermore there is little point because you don't have a physical head flying about looking for segments on a spinning disk.)

As I suggested before, it might be better to clone you C:\ drive back to the old 500 GB SSD, then you will have a full 1 TB to use for file storage.

Re: W10 peek-a-boo for Junes update

Awww, for goodness sake. That's 250GB wasted isn't it.

There are so many good things about SSD's but that's one of the bad things. You can't defrag them to compact everything.

Yes, using my old 480GB SSD for system/programs would make the most sense under the circumstances.

I don't know what 'compressing does but would compressing the drive not work?

Is there no way of formatting the old drive and copying the system/program/app files from 'C' to it so that it writes in a compact manner?

Sorry if my questions sound stupid but I don't know and the only way is to ask.

Thanks again, Nigel, for your patience.


Keith

edit - Just had a thought, if I clone 'C' drive onto a spinning hard drive, defrag that hard drive, then clone it back into 'C' drive, would that compress all data so that the borders and everything else is compressed? (if that makes sense)

Yes, that is one way of doing it, and probably best and safest way.

Compressing wouldn't help.

If you were going to clone everything back to the 500 GB drive it wouldn't really matter. You can of course use the empty space on your drive, but you just cannot create a partition smaller than the outermost data blocks if that makes sense.

It is also worth mentioning that SSDs' are designed to write data randomly across the storage space to prolong their life. If they always wrote to and read from the same allocation units (which is how spinning disks work in an ideal world), they would wear out a lot more quickly.
