Windows 7: which SSD size needed


20 Aug 2010   #11

 

Turn off the pagefile for your SSD. It isn't necessary with 8 GB RAM and an SSD. You can also set windows to place restore points on a different HDD, which should free up plenty of space. Turn off hibernation as well.

i don't have the SSD yet, and I had problems with some programs (i.e. Maple) that didn't run without pagefile despite the huge RAM.

anyway, the problem shifted since my virgin Windows 7 doesn't sem to start anymore (tired multiple times reinstalling). I don't know if it is related, but when I tried to put on my image with the Macrium rescue disk it had me do something to the boot sector. don't remember what...

So I install Windows 7, do some updates with coubpel of restarts, and then at some time it can't start and the repair doesn't work either. Grrrr...

SSD's
There is a technique called over provisioning, or short stroking, the SSD. It basically means not allocating 100% of available drive space to the OS partition. You leave a percentage totally unallocated, bigger the OS drive, bigger the unallocated space. In my case, I use a 90Gb array with only 80Gb allocated to OS.

SSD's have a different life span than spinners, so you want to reduce the SSD writes to disk wherever possible. I am getting ready to install XP Pro on a single 30Gb OCZ Vertex. I intend to only put the OS on the drive with a 27 GB partition. That will give me room for all updates now and in future. All other software will be somewhere else. I will let the SSD herd all my spinners.

This is going to be a home server so I am not worried about performance like I would my Vertex RAID array machine. That/this machine is only SSD drives.

ps: windows wants a pagefile, your better off making a small one and then useing a technique where you lockout the page file forcing OS and apps to all ram. I use this it does help a smidge.

luck

Imaging to SSD's seems problematical, I would advise a clean install. With OCZ Vertex SSD's theres software called Sanitary Erase, Whenever you are reinstalling anything to an SSD, the SSD must be cleaned properly. S.E. returns an OCZ SSD to factory fresh condition. Now you can let Windows 7 install away. It will align and format the SSD all by itself. Your only choice to make is the primary partitions size.

I think I fixed my booting problem. Windows 7 update seems to have a RAID driver for a non-Intel RAID and installing that via update screwed it up... anyway. Back to SSD.

Once I have my SSD I will do a virgin install.

On the page file: since some software has problems without it (regardless of RAM) I'll leave a GB or so. will see.

I know the SSD itself has " hidden" extra 7-13% of NAND that the OS doesn't see and uses. and that is used for cleaning etc. I understand that. But will I need significant SSD space that is visible to the OS? I mean if I need 50 GB for the OS, is a 64 GB enough?

50 gb is adequate and you can always install programs to a second hdd without problems, and I would recommend doing that for any programs that aren't really heavy on the system.. like firefox or a media player

You always need a PF regardless how much RAM you have.

However, if space is needed on the SSD:

1) I would recommend leaving a small 500MB PF on the OS Drive (SSD) and a main PF on a secondary drive to save space, rather than disable it altogether.

2) disabling the hiberfile if you do not use this feature will also free up some space.

3) Move Music, Pictures, Video to a secondary drive. Possibly Documents as well.

4) Make a folder for Games on a secondary drive and install them there.

5) Turn off Disk Indexing for the SSD Drive

6) Leaving Super Fetch on will help performance over time.

7) Disable Windows defrag for the SSD .

(7 should actually do this on its own after the 1st run of WEI. It may turn off SF as well, but I would turn it back on 'auto")


The limited writes, IMHO, is blown way out of proportion.

I don't plan to install large additional software (have Revit etc.). but also think with updates etc, the programs get larger and windows updates add space too.
Wow that is huge. I have Windows 7 Ultimate 64 and it only takes up 16GB on my C drive. I have my swap file on another drive (for speed but it is not used) and disabled hibernation. Also disabled Restore as well. I prefer my own backups saved to another storage device rather than risk it on the same drive it may die on. I also install all my apps on another drive as well to keep C free.

As you can see it does not take up that much space. Having said that I remember my old Amiga A2500 which had a 1GB drive and that was huge at the time and of course it was never going to fill up.

In my opinion, no.

If that 50 GB cannot be reduced, then you have a 50 GB floor, with less than 14 GB free.

I'd want more than that available, considering future new applications, future Windows updates, future upgrades of existing programs, etc.

It's up to you to determine if the 50 GB can or cannot be reduced.

I disagree. You should still maintain a page file...but can make it smaller as it won't be hit much.

Yes, some apps are going to check for it's presence and require it...hence the reason I wouldn't get rid of it completely.

Yes, I turned off hibernate on my machine. It boots so fast from my SSD...that I don't hibernate it or use hybrid sleep.

I would hate to have to move my games to a secondary drive, as the load times for these games improved greatly with the SSD...probably the one thing that really took advantage of the SSD's and made the biggest difference.

Agreed.

Yes...I couldn't agree more completely. It's the classic case of making a mountain out of a mole hill.
