Results: Power Consumption And Efficiency

Seagate Laptop Ultrathin HDD Review: 500 GB In 5 mm Of Space
By , Achim Roos

Power Consumption

The Laptop Ultrathin HDD’s read and write results turn out to be thoroughly average (which isn't bad for a product designed for constrained dimensions, not for blazing speed). But its power consumption is another story entirely. Since the 5 mm drive only has one platter to spin, it doesn't burn a lot of juice. Seagate posts good numbers overall, not always topping the charts, but certainly trending higher than it did in the performance benchmarks, drawing between 0.5 W at idle and 2.7 W at maximum data transfer speed.

Efficiency

The ratio of performance to power consumption gives us some insight into each hard drive's efficiency, and the usage scenarios to which they're best suited. The streaming writes and database efficiency of Seagate's Laptop Ultrathin HDD are top-of-the-line compared to other 2.5" products spinning at 5400 RPM.

    For the hard drive being benchmarked, is it possible for tomshardware to color the text to make them easier to find in the list?

    for example http://i.imgur.com/VXwTs6y.jpg

    it only takes about 3 seconds to do (even faster if you are in the process of making the chart and not changing colors in post)

    makes ya wonder how small this format can go. impressive.

    Its main selling point is the fact that it's only 5 mm thick, instead of the 9.5"

    Think you meant 9.5mm there.

    At least it's not got proprietary connectors like the WD 5mm ones do. Think you need to add one of those to the benchmarks though - it's Seagate's biggest competition.

    This would be a good choice for a mITX build when you want budget storage to complement a SSD.

    Not really; it'll cost significantly more per GB than a 9.5mm drive, but all the bays are fine with the thicker drives.

    Regular thickness drives are $60-80 and this one is mentioned to be under $100 with no price given for the consumer market. I wouldn't mind paying a small premium for a drive that utilizes 53% of the area of a 9.5mm drive.

    The thing is there's nothing you can do with the extra space; it's a couple of millimeters in the middle of an HDD cage

    No point in 5 mm HDD, any laptop can install regular 9 mm HDD
    More expensive, more slower

    Please Tom's, get rid of the new format for pictures having the caption as an alpha-blended banner overlapping the bottom of the picture. This article's second picture, which attempts to illustrate the thinness of the new drive, is ruined by the new captioning method. Use some intelligence and put the caption UNDER the picture. This is the way that has worked for decades in both print and online. Why change something that works for a system that fails?

    Nope, ultrabooks often have 7mm slots or none, and soon I'd expect that to be 5mm.

    XngXtuHl, this HD is really about fitting in the 'ultra-book' form factor.

    Who said anything about a HDD cage?

    There is one interesting use that I can think of. A new laptop, in place of the DVD drive, you can have 2 slots for ultra thin hard drives in addition to a standard SSD.

    Allowing for a lot of extra storage, or RAID 1 bulk storage since it is common place for laptops to use SSD's now but it is also well known that you should always backup your important data and keep bulk data off of the SSD. (SSD= OS and applications only)

    @someone somewhere

    Remember the old wash tub disk drive disk packs? Even they were only like 6" tall tho'. :)

    Why not go with SSD? stop using these mechanical drives already, when I shop for monitor I can't find crt anymore, lets make it the same.

    You can get an answer to your question in an article on this subject - the article on this page (if you read it)

    This technology should be used with iPod classics! They're so unpopular because the only ones who buy one are people with alot of music and videos, and the highest capacity they offer is 160Gb. That's not very much for movie files, especially HD/ Bluray ones. Apple might be better off adopting technology like this!

    I'd have to wonder about the durability of a drive like this, especially in a tablet or other thin form factor that might flex, even a little.

    The current hard drive based ipods use 1.8" 1 platter drives, not sure of the thickness, 7mm?
    so they'd have to have a larger chassis in length/width but not as much thickness.
    With current platter densities, Apple could put in a 250GB 1.8" 1 platter drive in their ipods

    Reliability?
    I'm more interested in reliability than speed.
    One would suspect 1 platter to be more reliable than 2, 3, or 4 platters.
    The article doesn't mention how many heads, 1 or 2.
    Again, I suspect 1 head more reliable than 2 heads.
    Unfortunately, Tomshardware can't test 5 year reliability, but there might be data somewhere on improved reliability of 1 platter and of 1 head.
