Western Digital - no failures (currently have about 25 in use, from 80GB to 1.5TB)
Hitachi (IBM) - no failures (have 3 in use, 120GB/250GBs))
Seagate - 3 failures
Samsung - 7 failures

All used over the last 10-years - just my experience with the different manufacturers... ;)

Wow.. good stats report.. but how come you used so many hard drives?

the 64mb cache drives still comes with 5yrs .... the rest are all 3yrs

I was just wondering, what is really the different between 32 and 64? Like i know it's fast and all.. but what exactly is the function of then cache?

the cache is used to hold data that is transferred from the IDE / SATA / ISCSI bus to the HDD platters and back :) The bigger the cache, the more data can transfer simeltanoulsly
 
hmmm is the cache flash memory?
 
The what kind of memory is it??? AFAIK you only had flash and disk....
 
It's volatile memory (loses information when power is removed, like system RAM). It acts as a temporary buffer while the Hdd head is reading/writing.

The real performance difference between 32 and 64mb cache is 0. Import thing to remember is that it is not technically a cache, but rather a buffer. The main function of the buffer is to sequence writes and buffer reads (i.e. the heads read a block that is not required, but buffers it should the block be necessary later). The chance of of a system reading a file from the buffer, as if it were a chache, are pretty slim due to the small size of the buffer (top end SANS can have 1TB of cache, this is a cache!).

Think of the buffer as being a method of assisting the HDD to work at closer to maximum performance, rather than a method of caching data for repeated reads/writes.

ah ok, thanks for the info :)
 
But all in all.. it's just the higher the better.. And there is this something else I want to ask.. there is something called a 3G sata? what is that really?
 
Higher <> Better - unless you believe marketing. 2c is twice the amount of 1c; but having two cents does not make you rich - if you multiplied it 100 times, you would still not have a lot of money. Its the same with 32 vs. 64 MB Cache....

3Gb Sata refers to the bandwidth between the cache and controller i.e. the maximum transfer rate from HDD cache (buffer) to RAM. Like the cache, more is not better, since the platter to cache speed is a fraction of the 3GB rated speed, i.e. the rate at which the heads can read/write data is slower than the rate at which the bus can move that data....
 
everyday operation like ur os drive then the seagate, but for reliable storage its wd. try filling a seagate to d brim and c how long it lasts...
 
Both are good, both fail. If your data is important, BACKUP!!!!!
