![]() i must ask why hasnt anyone said anything about algining the partition you install win 7 on.... depending on how you let win 7 install make your partitions it may or may not align it... regardless you should align it to 64KB for best performance.
OCZ Forum - View Single Post - How to setup Core V1/2, Solid, Apex, Vertex SSD with aligned partitions using USB (if available on the drive) or SATA. Updated to show how to use Vista recovery disk Do the same steps using the win 7 install... offset by 64KB, and dont let win 7 do n e formatting of ur ssd, just install it on the ntfs partition. Probably one of the best speed tweaks out there! |

![]() It's done for performance. Did you read the link in nd4spdbh's post right above yours?

According to the OCZ Forum, this procedure is NOT necessary (at least under a new installation of Windows 7) on their Vertex series of SSD drives. |

As it applies to SSDs you do the same thing, except you want the clusters to match the block size of the SSD as best as possible. Since SSD blocks are typically larger than one cluster, many people stay with multiples of 64. The reason that this problem exists, is because Windows XP uses 63 instead of 64. Which throws off every boundry on the disk (which could make writes 2x-3x slower in some cases!). If you are using Windows Vista or Windows 7 to create the partition it will align it automatically. Windows XP is the only OS that 'requires' alignment. Anyway unless you are using Windows XP to create the partition don't worry about it. |

![]() i will say this does apply to windows 7... i installed win 7 and it aligned my partition at 63 sectors. now i will say that i was messing around with partition in the win 7 install so maybe by default it will do a 64sector offset but mine didnt... so just check when you get your system up n running.
needless to say i ended up aligning to 128sectors (64KB) as per this huge ocz thread Guide Partition alignment importance under Windows XP (32-bit and 64-bit)..why it helps with stuttering and increases drive working life. - OCZ Forum |

![]() Overall, a good (let's say) "article", I mean there's a lot of good info in it (esp. for newbies), however, I have a few problems with it (i.e. things to add and/or correct):

So you see, a prefetch file is only a some kind of map (containing references to files which a respective executable loads on launch), if you want to also see Ed Bott's article titled "Windows Expertise: One more time: do not clean out your Prefetch folder!" for more info about this. With "totally ridiculous" I am referring only to the part of text that says that disabling it "frees up RAM". It's true though that having it enabled causes writes to SSD now and then, but perfetch files are usually just a few kBs in size. /EDIT: And one more note: all this above (my explanation of how it works etc.) regarding prefetching applies only if Superfetch in Windows 7 is not completely different thing than prefetching in let's say Windows XP. Quote:
By the way, other related user-prefs (that is if you want to disable disk caching) in "prefs.js" or "user.js" files are the following ones: user_pref("browser.cache.disk_cache_ssl", false); user_pref("browser.cache.disk.enable", false); user_pref("browser.cache.memory.enable", true); Note that by default these do not exist so you need to add them by yourself manually.

Finally, also see the "No pagefile by default on Dell Mini 9?!" thread here on MyDellMini, and optionally also the "No pagefile by default on my new netbook, is this OK?!" one on forum on ArsTechnica website, that I opened about this. |
