Laptop Hybrid SSD/HDD or (Pure) SSD?

It all depends on personal needs.
Not all of us have to carry around their holiday photos from the last ten years or massive movie collections.
If mobility is an issue, then you might think twice before fitting two storage disks into your laptop. SSDs are pretty much on par with HDDs re power consumption.
I'm using a 120 GB SSD and still have plenty space to play with.
I still have the auld 701 with its massive 4 GB SSD but since I have a couple of SD cards space has never been issue there for me either. You can put a lot of music and the odd movie onto a 32 GB SD card.
If you're into image/video editing you'd certainly want a platter hard drive unless you don't care to wreck your precious SSD rather sooner than later.
As usual, in computing there is no one fits all solution to such questions. 0 -

thanks
Is it hard to install them instead of what comes with laptop? Is it just a matter or unscrewing the old one and popping the new one in? I am thinking of buying a new laptop and replacing the hard drive straight away which means my laptop warranty might go with it.
It normally is, unless you're talking about a Eee 1005HA which I had the pleasure to take apart recently.
Normally the HDD bay is easily accessible, 1 or 2 screws and the hatch comes off. The HDD itself is usually fixed with 4 screws inside a casing which in turn could be fixed with one or two srews to prevent the disk from sliding out of the connector by accident.
To be sure to be sure, look up g00gle for "disassembly" or "HDD replacment" followed by make and model of your laptop. You may find even a video tutorial on Youtube. 0 -

How do you figure this, as SSDs lack the main moving parts that the HDD would have (platters, etc)?
You think SSDs are powered by thin air.
If you're using a hard disc AND a solid state disc in a computer, you'll likely consume twice as much power required for your storage device(s). Or nearly... Anyway, there's alsways a price to pay. 0 -

Well, SSDs are better in "running" pretty much everything. Do you mean which applications are rather harmful re write access? That would be web browsers in particular because the write to disc as if there is there is no tomorrow.
But that is easily diverted into a RAM disk.
While it is true that MLC chips have a limited lifespan, the problem is vastly overstated, even with very heavy write usage you could realistically expect it to last at least as long as a HDD and probably far longer. The chances are it will become obsolete long before it wears itself out.
By all means turn off a few extremely write heavy features like Hibernation, but in general peolple shouldn't be completely paranoid about write endurance and just enjoy the benefits that an SSD brings
http://www.toshiba.com/taec/news/media_resources/docs/SSDmyths.pdf
Absent any industry standard usage model, Toshiba
developed an internal model and studied usage patterns
for normal and heavy users.
To even begin to reach a
conservative endurance limit of a 64GB1 MLC NAND-based
SSD with wear-leveling technology, a mobile user would
have to write approximately 40 Terabytes2 (forty trillion
bytes) of data over the expected five-year life of the drive.
That’s equal to approximately 22GB of new data per day,
every day – or enough to fill 4.6 DVDs, or 32 CDs daily.
With a 128GB drive, for example, the wear would be
spread over a larger storage area, effectively doubling the
average daily write limit to 44GB, or more than 9 DVDs.
In the Toshiba usage modeling study*, typical users wrote
approximately 1.4GB/day, and heavy users wrote about
5.2GB/day.
Further analysis showed that auto-save and
hibernate features could increase total data written per
day to 2.4GB for the typical user and 9.2GB for heavy
users. Although the specifications of Toshiba MLC SSDs
exceed the 40 Terabyte example provided, it may help
demonstrate that the endurance limit is so far beyond the
likely usage of a typical mobile computer user that it isn’t
a realistic cause for concern.0 -

Quite, but you don't have to push your luck either when it is easily to be avoided, no?
I f you redirect your browser into a RAM disk (i.e. via Sandboxie, which will also add another layer of security) it will actually improve the browser speed as a RAM disk beats even the fastest SSD on the market... by a country mile.0 -

Of course it should a consideration which is why there is no harm in turning off things like hibernation, which dumps the entire content of RAM onto the SSD whenever the computer hibernates, or moving your large download/temp folders etc. But worrying about a few MB of brower caching per day seems a bit OTT, after all how long do you need that SSD to last, 10-15 years?, I certainly will have been through a few by then. :pac:
Also isn't a RAM disk way OTT for browser caching, after all you will still have to wait for the dynamic parts of the page to come back across the wire before the page loads completely, and even the slowest of HDDs is orders of magniture faster than broadband.0 -
