I've got an HP G71, and bought one of thosse SSD/HD replacement Caddy to replace the DVD in the Side Bay with an SSD caddy.

it was really easy to do myself, and i bought a huge Samsung 500 gig SSD.

I also replaced my original HD with another of the same SSD, so my laptop is substantially faster, and between the two drives a terabyte of total drive space.

Personally, my new laptop is 32gb ram, with multiple SSD drives (I have plans for presentations with many VMs running...). I'm still getting stuff installed on it, so I hope to start using it soon.
What kind of laptop did you get that allows for multiple SSDs? I'd love to have something like that.
My HP allows multiple SSDs
What model?

Pavilion dv-7.

I can put in a third if I remove the dvd drive

And for those wondering about the 137, google - Fine Structure Constant and enjoy a lesson in quantum field theory.

What a number! Thanks for that.

Have I mentioned these 2 things lately:

1. I can't stand ORM tools and the queries they create

2. I can't stand when developers create databases without a data professional involved.

Thanks,

Well, there wouldn't be anything that could be sad, so maybe it wouldn't.

According to one main multiple universe theory, those universes do exists, as do just about any other you can think of. Universes more like ours are separated by structures called "branes", sharing the same mega-universe or "space", but the more exotic ones are in different sorts of space entirely.

I meant that our existence would be impossible, so that would be sad. Of course we wouldn't be here to be sad for it, but we are here now, to think of the possibility of our non-existence. So thinking of our non-existence is sad. :hehe:

As for multi-verses, quantum theory does make those a little more plausible because it does explain some odd results in some experiments. In general, it's fun to think about, but who knows? It's all very sketchy at this point. I think it's like we've discovered a pebble, and are trying to determine what our whole solar system is like, based upon one little rock.

I love the time and money that using an ORM brings to the table. They are one of the greatest tools in a developers toolbox.

Here's part of the reason why I hate ORM tools and developers designing databases.

I'm trying to do some tuning, via indexing and I'm fighting with why a query that has an index that covers all 3 criteria is scanning and not seeking. Then I see why in the execution plan, Convert_Implicit(DB.schema.table.columnA) because columnA is defined a NVARCHAR(50) because it could be an int, a GUID, whatever, and the ORM tool is passing in parameter INT because the value being passed is 1234.

I should also mention that this column is the most selective of the 3 columns in the where clause by large factor. The 2 other columns are a Type, that currently has 5 distinct values, and bit column. So once we get a good amount of data in that table I'm pretty sure any index that doesn't have columnA as the leading column will require a scan, and, if the app were better, an index with it as the leading column will be able to seek.

Oh and another developer used DTA to recommend indexes and of course it always adds the bit column as the leading column of any index.

No.

An unselective leading column does not mean a scan (and I've often created indexes with a bit as the leading column). It's not going to be the most efficient seek, but unless there's no sargable predicate on the leading column, you will get a seek.

If the entire of the index is unselective and is not covering, then SQL will likely switch to a scan of the clustered index (unless there are other covering indexes)

I guess I'm paranoid about any leading index column that has very low selectivity. As most folks know, while they can really help with SELECTs, they're absolutely horrible for INSERTs unless you have a fairly low FILLFACTOR because of the extent splits that occur behind the scenes during INSERTs. Such indexes can cause massive, immediate timeouts. The reason I'm paranoid is because I saw it happen when such an index was released to the "yellow-ad" databases for Expedia.com where virtually every INSERT from the application timed out.
