Win7 Bootcamp Turn Off Auto Defrag

[OSMac]

Noticed with a Win7 bootcamp install the SSD is not detected and scheduled disk defragmentation would best be turned off manually.

You may also want to turn off hibernation to save from 2-4GB of disc space.

A full install of Win7 takes about 10GB and runs excellent.

The few things I always do on W7 w/an SSD:

• turn off defragmentation
• disable hibernation (on my boot SSD for the Mac Pro, this gave me 12Gb back!)
• turn off system restore
• turn off drive indexing
• if you have at least 4Gb ideally 8Gb of RAM, disable the pagefile

I have Win7 on my iMac, and have been using various iterations of Windows on various machines all the way back to Windows 3.1, and I don't recall having to turn off scheduled disk defrags. In my recollection, you have to turn that on if you want it.

Defrag is scheduled by default.

was wondering what defragging would do to a SSD?

no improvement, no harm, no nothing?

and I never knew the hibernation would take up so much space! (12GB )

thanks

It would dramatically shorten its lifespan as SSDs are rated on number of write cycles. rewriting data over and over for defragging is one task you can do, to kill a SSD prematurely.

and still it wouldn't improve its performance (write/read speed-wise) right?

Correct, so you're not really getting any benefit. The concept behind defragging is to have your data in contiguous blocks so the hard drive actuation arm does not have to travel across the hard drive platter to read the data. SSDs are all electronic so there's no latency in reading data.

Thank you.

I have been a PC user and attracted by the new MBA recently, so obviously a new member here.
I have already learnt so much visiting this forum.

Now back to the topic, why should we disable hibernation on W7 with a SSD?
SSD is really new to me...

Hibernation will reserve space on the SSD equal to the amount of ram you have installed. Turning it off saves that space either 2GB or 4GB.

Its designed allow the system to copy your machines running state to HD and shutdown. With the Air's SSD you can sleep or full boot very fast anyhow, hibernation is not really advantageous, unless you wanted to save the machines state for more than the remaining battery standby time I guess.

It's optional wont hurt to have it on, just uses the extra SSD space and may seldom if ever be used.
