Hitachi drive for PC
based on the below study
www.extremetech.com/extreme/175089-who-makes-the-most-reliable-hard-drives
would it safe to assume the same for PCs also (as against RAIDs for big servers)

thank you.. these info will help me from investing in a less than ideal choice...
>>I would not use that HDD period when I had the choice for a true enterprise class server drive for a few dollars more
dlethe, would you see such drives (enterprise class server drive ) sold in newegg.com or amazon to get it for a heavily used critical workstation..
if indeed they are available in newegg or
http://www.amazon.com/gp/bestsellers/electronics/1254762011
, can you point out a couple of them for a budget conscious user. (is the "few dollars" mentioned in the above phrase 5$ or 30 or 50 or 100 etc).. let's say for a 1TB space drive.
can you get them in retail stores like Staples, Best Buy, Radio shack etc? (in usa)

from your description,
so far i have two:
http://www.amazon.com/Seagate-Enterprise-Capacity-Constellation-ST1000NM0023/dp/B00BV18XIS
http://www.amazon.com/Western-Digital-Cache-Desktop-WD1003FZEX/dp/B00FJRS6FU
would you consider them fitting your description above as a few bucks more but significantly better?
my local walmart doesn't not have any internal hard drives
staples has only 1
http://www.staples.com/Toshiba-2TB-35-Desktop-Internal-Hard-Drive/product_571926
this is not enterprise category is it?

>>You DO have a SAS controller, right?
no, i don't.. but i am willing to upgrade..
can you give a reco from
http://www.amazon.com/gp/bestsellers/electronics/3015424011
or SW equivalent?

What is your budget and desired usable capacity, and how is this system used?
ASKER
budget - it will be an investmenti ; i can convince user; so not willing to put a limit on it now.
will be used as a trading computer. potential to be running 24/5. right now all it got is a plain 7200 disk, far from ideal.

No, I am a huge fan of SSDs. But my problem with them is people generally misuse them. Case in point, you don't put SSDs behind RAID controllers unless the controller is designed to support them. You risk data loss and take a big performance hit due to write amplification issues.
Other problem is that SSDs do develop bad blocks, so they are not a protection against data loss. They also lose data over time if the blocks are not read periodically. SSDs are VOLATILE devices.
Two HDDs in software RAID1 also will generally outperform a low-cost SSD in reads, because software RAID1 does read load balancing. Also two HDDs in software RAID1 provide protection against data loss, and it will generally cost less.

I don't bother with RAID on desktops.So the whole "SSDs are bad behind RAID controllers" is not important for my usage.
Keep frequent backups and leave RAID for the servers.
I do for 100% of mine, software RAID1. My concern is not so much backup but as corruption due to unrecovered read errors, especially if the error is in a program under development.
ASKER
from big picture, i'll remember
ECC / raid
and
backups + regular monitoring.
as being the most reliable and needful things to remember.
what will be a reasonable # of ECC bits to be considered moderate and what count will be consider fairly upscale and robust? i assume all manufacturers have their products in each category of ECC bit range products?
