Which is the better hard drive? SATA or RAID?
1) 500GB Data Security DataSafe (2x500GB SATA 3Gb/s 7200 RPM HDDs) 2) 750GB Data Security DataSafe (2x750GB SATA 3Gb/s 7200 RPM HDDs) 3) 1TB Data Security Dell DataSafe (2x1TB SATA 3Gb/s 7200RPM HDDs) 4) 1TB Performance RAID 0 (2 x 500GB SATA 3Gb/s 7200 RPM HDDs)
5) 1.5TB Performance RAID 0 (2 x 750GB SATA 3Gb/s 7200 RPM HDDs) 6) 2TB Performance RAID (2x1TB SATA 3Gb/s 7200 RPM HDDs)
Answer #1
SATA and RAID aren’t two opposite things. SATA (Serial ATA) is a way of transferring data to the HDD, and is faster than IDE. RAID divides data between multiple HDD. It’s your choice which HDD to get
Answer #2
RAID is not a type of hard drive, it is a HDD configuration.
There used to be two types of RAID back in the day, 1 and 0, now theres a few more which i havent kept track of.
The basic idea was that you could have 2 HDDs set up in two types of configuration:
one of them: 2 hard drives work simultaneously to throw out data to the motherboard – basically halving your hdd output times – faster computing but more prone to failure (and total loss of data)
the other:
2 hard drives working together, with one as the main disk, the other as a duplicate copy – all your files are basically duplicated – as it writes to one it wrote to the other – should your main screw up, you have an exact duplicate sitting in the system.
You have to decide what you want out of your system.
Of course my comment about the first raid type is a bit outdated – its not as volatile as it started off.
Answer #3
Just read up on RAID. I definitely don’t want it. A lot of issues have been reported with it.
Answer #4
fair do’s..
there is of course nothing wrong with just having that second hard drive in your computer (if your big on storage)
Bear in mind that although its nice to have say a 500gb HDD, think how long a defrag, or a format might take?
I like having a relatively small (160gb) hdd inside and a 500gb external <– havent and shouldnt need to format/defrag the external for a long time yet.
Answer #5
SATA 100 % sure
Answer #6
thank You for all your feedback, I appreciate it.
Answer #7
I’m guessing “Data Security Dell DataSafe” is dell’s implementation of raid for faster access/data transfer use raid, almost twice as fast as a single drive because data is coming from 2 duplicate hard drives
for data security on a standalone PC I prefer a 2nd stand alone drive to avoid the above mentioned(by you) problems
then just copy your stuff manually or with a backup progie
raid was originally intended for data security on servers, but gamers started using it to get faster load times at startup and levels
breaking a raid is a major pain in the butt
Answer #8
Good info . Thank you. There’s nothing like feedback from users. Better than the propoganda that compamies spit out.
