Introduction and Specifications


It has been a while since we took a look at some hard drives here at PC Perspective. While seemingly everyone is pushing hard into Solid State Storage, those spinning platters have gotten the computer industry by for several decades, and they won't be going away any time soon so long as magnetic domains can store bits for cheaper than electrons can. SSDs have been eating away at the market for OS and single drive mobile needs, but when it comes to bulk storage, nothing beats a great hard drive for the money. Since many users would rather avoid maintaining a large array of drives, getting the capacity of each 3.5" unit higher is still a need, especially for storage hungry consumers. Enterprise units have been pushing into 8TB territory lately, but the consumer sweet spot currently remains at 6TB. Western Digital entered this area in July of last year, pushing their popular Green and Red lines up to 6TB. While the capacity was great, those two lines are mean to be power saving, slower spinning drives. When platter speeds are low, the laws of physics (and of rotational latency) kick in and dictate that they could never perform as well as their 7200 RPM counterparts.


...and now they have filled that gap, with their Black and Red Pro models now made available in up to 6TB capacities. To clarify the product lines here, the Green and Black products are intended for usage as a single drive, while the Red and Red Pro are meant for operating in NAS devices and use in a RAID. The two drives in this review are the faster spinning models, so we should see better performance all around. Spinning those platters faster means more power drawn and more heat generated by air friction across the platters, as we can look into below:


Western Digital Red Pro 6TB:

  • Model: WD6001FFWX
  • Max Sequential Read: 214 MB/s
  • Form Factor: 3.5”
  • Interface Type: SATA 6.0 Gb/s (SATA 3)
  • UBER: <1 in 1015
  • Power (active/idle/standby): 10.6W/7.4W/1.6W
  • Warranty: 5 years

Western Digital Black 6TB:

  • Model: WD6001FZWX
  • Max Sequential: 218 MB/s
  • Form Factor: 3.5”
  • Interface Type: SATA 6.0 Gb/s (SATA 3)
  • UBER: <1 in 1014
  • Power (active/idle/standby): 10.6W/7.6W/1.6W
  • Warranty: 5 years

For comparison, the slower spinning 6TB Red and Green models run at 5.3W/3.4W/0.4W. Lesson learned - moving from ~5400 RPM to 7200 RPM roughly doubles the power draw of a high capacity 3.5" HDD. Other manufacturers are doing things like hermetically sealing their drives and filling them with Helium, but that is a prohibitively expensive proposition for consumer / small business drives, which is what the Black and Red Pro lines are meant to satisfy. It has also been proven that Helium filled drives are not the best if their track geometry is not optimized as well as it could be.

Toshiba Launches New 4TB and 5TB 7200 RPM Desktop Hard Drives

This week, Toshiba introduced 4TB and 5TB hard drives to the consumer space. Coming from Toshiba's Digital Products Division, the new drives are part of the company's PH3*00U-1I72 series and are the first four and five Terabyte 3.5" consumer hard drives sporting 7200 RPM spindle speeds (though enterprise and NAS focused drives have been available prior to these new drives).

The new 4TB and 5TB HDDs are 3.5-inch desktop drives with four and five platters respectively. Toshiba is using Perpendicular Magnetic Recording (PMR) and Tunnel Magneto-Resistive (TMR) technologies to hit 1TB per platter. The 7,200 RPM spindle speed allows Toshiba to hit an average seek time of 10.5ms, and the 128MB of cache stores frequently accessed data. The new drives are paired with a SATA 3 6Gbps interface. Toshiba has included NCQ (Native Command Queuing) support along with shock sensors and ramp on/off loading safety features.

The new drives are compatible with Linux, Mac OSX 10.6, and Windows 7 or newer. Both the 4TB PH3400U-1I72 and 5TB PH3500U-1I72 come with a three year manufacturer warranty.

The 4TB drive has an MSRP of $299 while the 5TB model has an MSRP of $399. Fortunately for digital hoarders, the drives are currently selling at prices below the MSRP. The 5TB model is being priced around $320 while the 4TB model is priced between $220 and $240 at the time of writing depending on your retailer of choice.

Seagate Will Cease Production of 7200 RPM Notebook Hard Drives Later This Year

Seagate Technology, the world’s second largest hard drive manufacturer (by market share), recently announced that it will be ceasing production on notebook hard drives featuring 7200 RPM spindle speeds. According to X-Bit Labs, Seagate Director of Marketing and Product Management David Burks stated that “We are going [to] stop building our notebook 7200rpm hard disk drives at the end of 2013.”

Stopping production of high-end notebook hard drives is a curious move for a company that is still dependent on hard drives to survive--with just a toe in the Solid State space with its hybrid hard drives. On the other hand, the market for such high-end notebook drives is likely feeling pressure from Solid State drives for pure performance at any price, cheap hard drives paired with a small mSATA caching SSD, and high-capacity 5400 RPM drives at extremely cheap prices. Users that would have traditionally favored 7200 RPM drives for an extra price during laptop configuration are now faced with more choices on the performance at modest price increases front with caching options. Further, with the advent of interfaces like Thunderbolt and USB 3.0, it is now more acceptable to go with a low capacity, cheaper, Solid State Drive for the operating system and applications while using external hard drives for your storage needs without incurring a transfer speed bottleneck that USB 2.0 exhibited.

Reportedly, Seagate will stop production of its Momentus 7200.4, Momentus 7200.2, and Momentus Thin notebook drive lineups. Further, the storage company will put more focus into further fleshing out its Momentus XT drives. The XT series features a spindle hard drive and small bit of SLC NAND flash for caching frequently accessed files. Hopefully the renewed focus on its hybrid hard drive series will result in drives with larger caches. That may necessitate the move to MLC flash to keep costs down, but I think a HHD with 32GB+ of MLC or TLC flash would be an acceptable compromise.

What do you think of the move? Customers will likely be able to get their hands on 7200 RPM mobile drives well into 2014 thanks to stock on hand at the various OEMs and retailers (and alternative options from other HDD manufacturers), so the fallout is likely to be minimal. Still, is it the right move for Seagate?
