Definitive 2TB HD Roundup: WD, Seagate, Samsung

22 thumbs up

Simpli Software's HD Tach RW is described on the company's web site as such: "HD Tach is a low level hardware benchmark for random access read/write storage devices such as hard drives, removable drives, flash devices, and RAID arrays. HD Tach uses custom device drivers and other low level Windows interfaces to bypass as many layers of software as possible and get as close to the physical performance of the device being tested."

As far as HD Tach RW's write and read tests are concerned, if you were expecting a different pecking order from the previous tests, you'll be disappointed. The WD RE4 2TB once again takes top honors with a write speed of 101.2MB/Sec. Behind that is a relatively tight grouping, with the Seagate Constellation ES 2TB (99.9MB/Sec), Seagate Barracuda XT 2TB (99.5MB/Sec), WD Caviar Black 2TB (97.5MB/Sec), and WD Caviar Black 1TB (96.9MB/Sec). The Seagate Barracuda LP 2TB is yet again the speediest general-purpose drive.

On HD Tach RW's read test, the Seagate Constellation ES 2TB elbows its way to the top with a read speed of 116.4MB/Sec. It is closely followed by the WD RE4 2TB (115.8MB/Sec), Seagate Barracuda XT 2TB (114.8), WD Caviar Black 1TB (113.1MB/Sec), and the WD Caviar Black 1TB (111.7MB/Sec). The Seagate Barracuda LP 2TB leads the general-purpose HDDs with a read speed of 98.4MB/Sec.

HD Tach RW's burst speed test is the first test we ran where we actually saw the two 6Gb/Sec drives take a performance lead. The WD Caviar Black 1TB had an impressive burst speed of 314.3MB/Sec, while the Seagate Barracuda XT 2TB had a burst speed of 287MB/Sec. All of the HDDs had burst speeds that were over 200MB/Sec--the Seagate Constellation ES 2TB brought up the rear at a still impressive 212.5MB/Sec. The best the 120GB OCZ Vertex Turbo 2.5-inch SSD could do on the burst test, however, was 198.8MB/Sec. The OCZ SSD's write and read speeds were still leaps and bounds ahead of the HDDs, though, with a write speed of 154.8MB/Sec and a read speed of 223MB/Sec.

Very interesting read.  I wish Hitachi didn't wimp out though!  I would love you guys to tackle putting these 2 TB drives in a RAID5 and how safe that is.  I see so many conflicting comments saying it is or isn't recommended.  I would love to add 4 of the 2TB Seagate drives to my NAS but still a little worried.  I read somewhere that WD states they don't recommend it.  Maybe someone from HH could address concern of mine.  Great read!

The WD "RE" drives are "RAID Edition" and have some RAID specific features, and would work in any type of array.

While the other drives may not have any RAID specific features, they will all work in a RAID 5 array. As long as the individual drives are compatible with your NAS, they should work in a RAID configuration within it.

Sup Marco, nice read.

That huge gap in the bang/buck chart between the 1TB and 2TB drives didn't shock me in the least.  One or two steps down from the largest size drive has been the best bet (if you get a current family drive) for as long as I can remember.  If I remember correctly, the 1.5TB drives actually have a slightly better price/TB then the 1TB drives right now.

So, nobody's noticed that when it came to the bang/buck chart, somebody forgot to factor in the size difference for the 1TB, resulting in a score exactly double what it should be?

Now before anybody thinks I'm crazy and/or not paying attention, take a look at the math.  Comparing both the 1TB and 2TB Cavier blacks, the 2TB scores 1.6% higher on the performance part, and the 1TB scores 16.7% higher on the cost-per-gb part.  So one should expect the bang/buck should show the 1TB drive coming out on top by 14.8%, or at the very least, in the same ballpark, that much should be obvious.  Instead, the difference is off by 129% exactly what you get if you don't take the size difference into account.

The RE4-GP numbers seem a bit off from the other too, but that's not quite as interesting anyway.

Great, thanks Marco

Another helpful review, what surprised me the most was how there was not much performance gain on the Caviar Black when going from the 2TB with 4 platters to the 1TB with 2 platters. I though not having those extra 2 platters would really increase performance on the 1TB but they were fairly close to each other. For the money though I would just get the 2TB as the cost per GB was a few cents more and that 5 year warranty is hard to beat. Again take your pick of these drives and pair it with a SSD and you are set!!!!!!!!!! Yes Big Smile

Thanks for the great 2TB HDD roundup.  I'm interested in getting a few of the 7200 RPM drives for a new QNAP or Synology NAS.

A few questions if you don't mind:

1.  It seems silly, but WD's Sep 2009 press release mentions that the RE4 2TB supports NCQ whereas the Caviar Black 2TB does not (see the section titled "Additional Features for WD RE4 2 TB Enterprise Hard Drives").  Is this correct??

2.  Are your benchmarks geared more towards single-user desktop usage?  In other words, could a multi-user NAS/fileserver scenario possibly exhibit drastically different rankings?

On the other hand, some say that the speed limitation of Gigabit Ethernet in the NAS scenario serves to bottleneck some of the raw performance differences among the 7200 RPM drives anyways...?

Goog article.

However, I think what would make this comparison even more useful though would be to also include comparisons of power draw, noise and heat.

These are also critical decision factors now - in particular if being used for a Home Server (e.g. WHS) or in AV equipment.  This is what has contributed to the WD Green drives popularity for example.

I felt that that was an excellent article, but would've liked to have seen some additional price/storage/performance comparisons involving some smaller drives, an SSD or two, and a raid setup.

Regardless, very informative, and something I will definitely be referring to as my 500GB drive is almost full.

 

Have you considered placing a commission linked link to Newegg for each of the drives? I know Hardocp has a deal with Newegg that all purchases made through one of their links is a 2.5% commission. If I'm going to spend the money anyone I wouldn't mind it benefiting HH.

Great article, I love the charts comparing all the hard drives. The caviar black 1TB is pretty nice :D.
