Which HD is faster

Postby Kibosh » Sat Mar 15, 2014 9:51 am

Hey all,

Probably an easy question for all off you.

I'm going to buy two new hard drives, being the Western Digital Blacks. The only part I didn't decide yet is how big they should be.
Should I go for 1TB and 3TB, or 2x 2TB? Or go for 2x 3TB.

One hard drive will be used for creating electronic music. This HD will be dedicated for that task so the speed is also important. The second disk will have multiple tasks but mainly keeping a lot off data and backups.

So is a 1TB HD faster then a 2TB, or 3TB disk?

Thx in advance.

Generally, larger size means platters with higher density, ie. faster.
Also, the newer the drive the faster, generally.

But to be sure you need to check drive specifications.
This has been an objective and completely impartial message from the propaganda bureau of DIREWOLF75. Thank you for reading. Have a nice day.

Hi Kibosh

Yes, Dire is right... not "huge" performance gains, but due to increased data density on the hard drive's disk ( or platter(s) ), the larger the hdd, the better its performance:

http://us.hardware.info/reviews/3550/3/ ... tage-hdd-1

The Hitachi Deskstar 7K4000 and the WD Black series are some of the very fastest consumer/desktop class hard disk drives you can buy ( leaving out the Velociraptor of course which is quite expensive compared to these other 7200rpm SATA drives we are discussing here ).

The WD Reds are good for NAS type setups ( data storage ) as they are near dead-silent and still have good speed, but at 5900rpm ( for lower power requirements and lower noise in a NAS type environment ) they are not as fast as the WD Blacks which are the fastest hdd's in the WD lineup, however some say the Blacks are overly noisy when doing r/w operations, so if noise bothers you a lot then I recommend you go with the Hitachi 7K4000 drives or the high end Seagate drives ( quieter in operation with similar speed ).

Noise ( active ) benchmark here:

http://us.hardware.info/reviews/3550/12 ... ise-levels

WD Blacks are the noisiest in that whole bunch!! :(

Just buy the biggest drives you can afford and be happy! :D

Thx guy's,

Didn't know that, the higher is also the faster. Learned something new today.

I already have a raptor running for the OS. And in the past I always had Western Digital so why change a winning team?

About the noise, I'm fine with that. It's only when the drive actually needs to work hard, for example when running Winrar or something that I really hear them.

Thx, gonna order 2x 3TB drives then. The 4TB are just too expensive.

I use a WD black as main drive as well, very reliable.

HDD's can have up to 5 platters usually. There is one exeption with an enterprise drive wich have helium inside and 7 platters.
So for example if a 5TB drive could be 5x1TB or 4x1.25TB the the latter one would be a bit faster.

I think 1TB is common today.. with 1.25TB or 1.5TB should be coming later this year probably in June/July with new 5TB-6TB drives.

Me 3, atleast until next week when ill be going SSD :D
Specs:

Intel Core i7 4930K, Kingston 32GB
ASUS GeForce GTX 770 4GB, ASUS P9X79

Another question: What speeds should I get when copying from one HD to another in MB/sec?

that depends on the file sizes... big files (100MB+) - near 80MB/s; medium files (jpg, 3-4MB+) - near 30-40MB/s; small files (like txt files, 4KB or less) could end up being 1MB/s or less.
What goes around comes around with interest!

True.

Here are some numbers for you to compare.

This is the WD Green 3.0 TB drive vs the Black Edition that you own 2 of:

http://www.pcmag.com/article2/0,2817,2372807,00.asp

Performance

Just know that you may not like the speed decrease that comes with it. Because these drives are intended to be eco-friendly and use less power, they run cooler and slower. WD wouldn't even tell us the drive's rotational speed—which suggests it's probably well below the 7,200 rpm threshold for standard desktop drives. Its results in our performance tests bear this out. Compared to a 7,200-rpm 2TB Caviar Black, it finished considerably slower in every benchmark we ran: 130.1 MBps versus 147.3 MBps linear read speeds in AIDA64; 128.4 MBps versus 152.1 MBps sequential reads in CrystalDiskMark 3.0, and 126 MBps versus 149.8 MBps in sequential writes; and a score of 4,077 versus 6,131 in the PCMark Vantage HDD Test. HDTune reported an average transfer rate of 109.5 MBps for the Caviar Green, and 117.2 MBps for the 2TB Caviar Black. AIDA64 reported an average read access time of 14.48 ms for the Caviar Green; for the Caviar black, it was 11.41 ms.


You should be getting anywhere from 50 Mbps to 117 Mbps average transfer rate ( copy ) depending on the file size ( and fragmentation of course ) on your drive...

Ok thx,

Speeds are good then. Got an average of 130 when copying some medium to larger files.
