ssd cache

[nootje860]

hi,

 

i am about to buy a SSD for my pc but recently i find somthing called ssd cache.

a lot of samsung ssd had the function.

but i found a drive that was better then the samsung cached one's.

so my questing is is the cache worth it.

a ssd cache is a small cache memory something like swap file for windows which is meant to be used with a typical hard disk drive

 

typical cache size of hard disks ranges from 8MB to 64MB but they are not enough for typical huge data transfers or read/write operations.

 

the idea of the SSD cache is to improve the caching of the hard drive by allowing the computer to use this SSD cache to improve read/write operation

 

Seagate and Toshiba currently have this technology in build into their hard drive with 8GB cache and the caching is controlled using their own harddrive firmware

 

Sandisk also has a SSD caching drive which is a stand alone 32GB drive which can be installed into current machines and all you need is to install their caching software which will manage what to cache or not.

 

but IMO if you have the budget, just get a SSD to install just the OS and frequently use softwares

Get a 840 Evo 120GB/250GB, OS on it and your programs + a few games and you'll be fine.

so ssd cache is on paper usefull but in real world use i can just by a drive without? is that what you are saying

[dragoon20005]

just buy a SSD straight away

 

no point investing on the SSD Cache unless you have limit space to install 2 drives like a notebook which only has 1 drive bay

 

then those hybrid ssd hard drive will be a good choice for speed and capacity

Get a 840 Evo 120GB/250GB, OS on it and your programs + a few games and you'll be fine.

 

but i hear from people that the drive can die very fast?

That's not even true that it dies "fast" or "faster" than any other SSD.

Everything can break but the 840 Evo is a good drive.

Well technically, if you write a lot, EVO will die about 3 times sooner than any other drive because of the tlc flash.

oke and what is tlc flash

[hojnikb]

Its a type of flash (the memory, ssd is using) that can store 3 bits in a single cell. MLC can take 2 bits and SLC can take 1 bit.

What this means, that more bits u take in a single cell, slower will it be and less times will you be able to write to before it completly dies (these cells are really really really tiny).

 

In other words, non of these concerns you
