Help with Windows 10 Install

where is my missing space?
This is a 960gb ssd. So I'm guessing it is in fact 1024gb with some over provisioning.

Why does it show only 894.3gb?

Looks fine to me.

960GB is the marketed size as 960,000 megabytes, or 1000 megabytes = 1 gigabyte. In reality, it is 1024 megabytes = 1 gigabyte. So to marketing 960GB = 960,000MB. In reality, if that drive were to be a true 960GB usable drive, it would be 960 * 1024 should be 983,040. So between that, formatting and provisioning you lose out on about 7% of your expected usable storage space in this case. Unfortunately this is a market-wide issue, where it is marketed at a smaller number than what Operating Systems and file systems actually use. Goes back to the basics of bits and bytes, storage theory and how it is handled at the software, kernel and hardware levels and some marketing guys trying to keep it simple.

My 960GB SSD reads the same last I checked. This has been an issue for decades with storage devices, how they're marketed... apparently 1000 is easier to market than 1024.

Here's a good Google search query that can give you some more actual details on the situation should you want more information on the matter: https://www.google.com/webhp?source...e=UTF-8#q=hard+drives+smaller+than+advertised



Edit: Also, use techpowerup.org for uploading images, then copy the BBC code to your post. Works much better for this forum.

Yes always have trouble with images. I'll try that.

So I should "format" the drive or just click "new"?
I want to leave some over provisioning for speed. Maybe create two partitions

1 that has 700gb for games and docs and one that has 80-100gb for Windows os

Does that make sense or have I got it wrong?

Sounds fine, but I wouldn't worry too much about that...if anything you should have a backup setup to an external hard drive or another drive in your system.

You can partition your SSD there for a 10240GB partition for the OS (100GB) and then the rest for DATA (I would format that at a later time to allow the Windows install to create the other partitions it needs during install). Select the OS partition you created, and click Install.

From the screenshot you show, you can click next to automatically use all the drive and format it so everything is the C: drive. Or you can create a 100GB drive, by clicking New and entering the size you want. Then selecting that and clicking next.

Frankly I'd run it all as a single drive...you won't really gain anything out of splitting it up. We used to do that years ago for speed and organization. But you really gain nothing here...if you had a smaller 100-200GB SSD I'd say make that the OS SSD and then use the 960 as storage. Then you'd have two drives with dedicated purposes. Windows 10 makes it easy to redirect your downloads, documents, pictures, videos and music folders to another location.

I wouldn't worry about the over provisioning, but then I haven't had much for problems with SSD and provisioning. So I personally would use all the free space I'm allowed. Also keep in mind, what you have access to isn't the total storage of a device. Especially platter-based hard drives...they come with extra space because every single platter drive ever created has bad sectors...they are impossible to avoid. So there's a buffer space where these are allowed to exist and you're not notified. By the time you are notified of bad sectors it is time to replace the drive.

I hope that helps!

In fact I want to split the ssd in two partitions because I'll do a lot of overclocking and gaming. In the past I've often had to re install Windows and having all my games on the same drive always meant I'd lose em all. Them and documents and have to reinstall everything. Having the separate partition for games and documents makes it easier to reinstall windows afterwards.

 

[Kursah]

Have you used the Windows 8/10 refresh feature? It is similar to a Windows 7 in-place upgrade in that it will reinstall vital OS components while leaving your installed programs and saved data untouched. I've been doing the OS repair process for years, check the Windows OS Repair link in my signature for more information.

I do see why you'd want to do that though. I personally prefer a dedicated OS SSD.

Ok so I just finished reading stuff on google for like 1hr. For me, it is soooooooooooooo important to understand something fully before making decisions. Everything is sooo much better when you understand.

Ok so now I know the existence of GiB Vs GB and MiB vs MB. I also have a general understanding of of over-provisioning and Trim.

Now here's the part I'm unsure of:

Does trim Complement (work with) unallocated space on the ssd drive? Or is it an alternative to "unallocated space"?

What I've come to learn is that SSDs usually have 7% OP from the get go. For personnal reasons, I'd like to make this 10-15% instead. I've got too much space anyways on that 960gb ssd.

What about trim, how is it useful to me? How does it affect my decisions regarding over provisioning?

Mega vs Mebibytes.

why would you overprovision an already overprovisioned drive? why care about such speed tweaks for mere games on an already fast drive type?

having games on separate partition doesnt solve the reinstall part due to the gross reliance on the registry & appdata, do you have internet limits or a lack of an external/alternate available 1TB for this to matter?

this makes me wonder, do SSDs physically move partitioned data around? on mechanical drives, the first partition is supposed to be on the edge, so it will never move, its files inside will fragment only in that designated edge area... if SSDs did this, it would wear out such an area, but if they dont, how is it storing partition data?

960 of 1024 = 9.375%, i assume that's what it physically has, personal reasons arent scientific, did you read some articles that detail the usefulness?

as for the bytes vs MB, it's not that the OS is hiding or lying, usually you can click properties to see the actual byte count to confirm that the size is right

What about my questions regarding trim?

What about my questions regarding trim?

no idea about trim since i've never used an SSD & dont get what the big deal is (i'll probably get/try one soon)

 

[DRDNA]

Well this will help a little with hard drive benchmarks and I have never seen Trim slow a hard drive bench down. As for Trimming the unused portion of the disk it would be irrelevant.

 

[AsRock]

Ok noted

What about my questions regarding trim?

For a example a 128GB drive typically has no over provisioning were a 120GB would have, this means it has 8GB to sort out what it needs to do with trim. Now looking at your and being 960GB makes me think it has about 40GB set for this.

If you want to add more to this leave some un-formatted space at the end of the drive.

Trim use unallocated space ?, i do believe so as this space helps the drive to do what it needs too to keep good performance.

Why does it show only 894.3gb?

See picture https://imgur.com/gallery/QxR1W

960 GB = 960 * 10^9 bytes = 960,000,000,000 bytes
894.3 GiB = 894.3 * 2^30 bytes = 960,247,313,203.2 bytes

Microsoft says "GB" (giga-bytes) when they calculate for "GiB" (giga-binary-bytes). There's absolutely nothing wrong. It's just Microsoft mislabeling units like they have been since forever.
