Hard Disk Drive

by

Our MacBook shipped with the Toshiba MK1653GSX SATA-II 160GB drive. MacBook 2.4 GHz machines with 250 GB also ship with Toshiba HDDs.  These drives have some of the highest areal densities per platter (254 gigabits per square inch). The 160 GB drive is a single platter design with two data heads. Average seek time is 12 ms with a track-to-track of 2 ms to a maximum of 22 ms seek. Seeks require 2.2 watts, read/write eats up 1.9 watts, while idle power consumption is 0.85 watts. MTTF is a disappointing 300,000 hours.

We also tested a MacBook that shipped with a Fujitsu MHZ2160BH SATA-II 160 GB drive. Track to track time is a faster at 1.5 ms and idle power consumption is better at 0.6 watts. Read/write is slightly worse at 2.1 watts. Seek power consumption is not reported. MTBF is also a disappointing 300,000 hours.

The unibody MacBook Pro ships with a different 5,400 rpm drive. We’ve seen MBP’s shipped with Hitachi Travelstar 5K320 drives (HTS543232L9SA02). While this specific model is not listed in Hitachi’s product documentation, the “SA0” designation typically refers to SATA 1.5 Gb/s designs as opposed to SATA 3.0Gb/s. This only makes a difference when transferring data from the cache to the host as 5,400 rpm notebook drives are unable to saturate a SATA 1.5 Gb/s connection. In theory, SATA 1.5 Gb/s connections require less power than SATA 3 Gb/s connections. Average seek time is also 12 ms, but the track-to-track time of 1 ms and a maximum full stroke of 20 ms is slightly faster. Seeks require 2.2 W, read/write is superior at 1.8 W, and active idle consumption is 0.8W. MTBF is not disclosed.

In general, these are run-of-the-mill notebook HDDs and we recommend upgrading to aftermarket HDDs. Time Machine makes it extremely straightforward to migrate your computer from one HDD to another (provided that you have an external drive). One good choice is the Seagate Momentus 7200.4. Not only is this a 7,200 rpm drive for added performance, but power consumption is improved to 1.554 W for seeks and 0.67 W at idle. MTBF is 500,000 hours. The Seagate drive offers a 5 year warranty as opposed to the 3 year of the Toshiba, Fujitsu or Hitachi drives that ship with the MacBook and MacBook Pro.

Solid State Storage

For our setup, we elected to go with solid state drives. SSDs are available in two formats: SLC and MLC. SLC is more expensive but offers added reliability and performance. MLC allows higher density memory chips to be produced, resulting in higher capacity drives at relatively affordable prices. Many of the early budget MLC solid state drives have been reported to have poor performance with small files (“stuttering”). The newer MLC drives that ship from Apple directly (manufactured by Samsung), the Intel X-25M, and the OCZ Vertex SSD line are all expected to have good performance because they use a different memory controller.

We elected to go with the OCZ SATA-II 64 GB SSD. Based upon Samsung’s SLC SSD technology, the OCZ solid state drive features a flagship 2,000,000 hours MTBF. In addition to the added performance and reliability that solid state drives can offer, the OCZ drive also adds considerable performance benefits over the standard 5,400 rpm hard drives. Power consumption during read/writes is just 0.5 W and 0.35 W with an idle of 0.2 W.The Intel X-25E is expected to offer the same level of reliability as the OCZ drive (2M hours MTBF) with even greater performance.

The enthusiast-priced Vertex SSD drives from OCZ have an MTBF of 1,500,000 hours and use a new memory controller which is supposed to prevent the stuttering that has plagued the other budget drives. The Intel X-25M has an MTBF of 1,200,000 hours. The Samsung MLC drives available in 128 GB capacities shipping in current MacBooks have an MTBF of 1,000,000 hours.

Going to SSD halved our boot times to about 25 seconds as compared to 56 seconds off the 5,400 rpm drive. Interestingly, the time it took to write a 2GB file was nearly equivalent to the boot time:

Time to Write 2GB File (1k blocks)

Factory installed HDD: 50.577 seconds (42.46MB/sec):

OCZ SATA-II SSD: 25.076 seconds (85.63MB/sec)

Why when comparing Macs do people always use Dell as the comparative standard. I'd rather buy a mac than a dell any day but I'd rather buy a pc than a Mac in general.

Another Apple advertisement, when will people finally see the big picture?
Just some facts though:
1. "...systems were rock-solid, running months at a time, requiring a reboot only after installing new video card drivers." and then "...secure timely updates and patches. I kept my system updated, downloading hotfixes even before they showed up on Windows Update." - Most of the updates on windows require a reboot - how come the author states the he kept up to date and then state that he only restarted when changing video drivers - something is not right
2. "I had no plans to switch from Windows to Macintosh permanently. All of my data had been stored on NTFS-formatted external drives and all my applications were for Windows. I was too careful, too savvy, and too poor to switch to a Mac." - If so really? Then why Mac? Why the formatting the drive process would be too time consuming? Why Vista in the first place? Why not linux and run the Adobe within the VM? Or at least build your system so things like this take 20 minutes to restore...? A Power User switching to a Mac because of ??? Design? Higher price to pay? outdated and less powerful components? Lack of easily available upgrades? Lack of ability to upgrade your laptop yourself? And I don't quite get the bit where the author states "... and too poor to switch to a Mac." and then says that he opted for the most expensive SSD version of MB... Then again - how did you actually get into troubles in the first place? Did you browse the web using InternetExplorer? which is commonly known as a "malicious-code-magnet"? Come on - antivirus software will not protect you from "user-errors"... Installing updates is one thing, browsing the web in a secure way is another... Ever heard of Firefox? Or Opera? How about some examples of the sites that made your box a part of a botnet? And why do you think switching to Mac is better than to Linux? Then again - why do Apple fans always praise the multitouch touchpad and "great" keyboard and then buy an external keyboard from Microsoft and external mouse from Logitech? Not to mention that quite a bit of text was about the beautiful screen of the mac and then again - I bet (only assuming though) that the power user will always use an external screen... But the most important thing here I think is...
Why would a power-pc-user switch from a high-end-desktop to a laptop?
Again - something is not right... I hope the part 2 of the article will shade more light on the issues above...
Kind regards
tinner

Every single Mac review article on this site now seem so "Heres a Mac, write an article about it and if it's good to us keep the Mac".
Can't deny apple stuff looks nice but the price for what you get beyond that isn't so hot.
Dell = overpriced junk, Mac = overpriced junk. No wonder they always find the prices about the same. Built it yourself = cheaper and a lot better.
This is a tech site not your local electrical superstore..It's what performance you get for your money NOT how one overpriced item stacks up against another overpriced item.

I didn't even get past the first page before the Mac advert kicked in...the author went scurrying for a Mac just because his meticulous security had been compromised once? Does he rush inside the house and never come out just because his umbrella let a few drops of rain in?

Now that Apple are using stock Intel hardware, you can now finally compare Macs and PCs like-for-like, and in every single OBJECTIVE comparison the Mac will always lose out now - overpriced for hardware or underpowered for price, whichever way you look at it the only reason to go Mac is Jobs-sucking and perpetuating elitism and snobbery (and I get that so often in my profession it's sickening).

I hate to use Dell as a comparison, but spec a Studio XPS identically to the 15" MacBook Pro and you're paying £500 extra just for a fancy aluminium body and a glass touchpad - even the multitouch features are software-driven!

So I agree with Belinda, it's what you get for your money and with a Mac you simply don't get enough to justify the cost.

Go to apple store , buy a copy of mac osx, patch it and install it on ur pc and everyone is happy. No more viruses!

Its against the OS X license to install it on your PC. Can ONLY install it legitimately on a Mac.

I would like to see the 7200RPM Hard Disk you mention added to the comparison table, you are comparing an OEM junk drive to something far superior. I'd like to see what adding a sensible hard disk would do to the performance.

Interesting that the 7200RPM unit you mention uses less power than the standard 5400RPM one supplied.

All I can say is that when my 22 year old sister bought her first laptop....a Mac... I lost alot of respect for her. With that being said, I understand why she bought a Mac

1.Fashionable 2.it's the 'cool' thing 3. ignorance/unknowledgable about what she is buying 4. she is most likely using it for constant facebook usage.

Now with that being said I would like to point out (espescially to the author) that if you are not a 16-24 year old FEMALE then you have absolutely NO exscuse to be using a Mac, whereas ny sister does.

I couldn't agree more with other readers of this article, Yet another Mac advert. I am fed up with SMUG Mac users and their claims we don’t get viruses. If OS X is so secure why then does Apple recommend using multiple antivirus products?
The vast majority of malicious infections are written for some sought of financial gain, so it’s obvious that the coder would spend their time targeting PC's as they make up 90% of the market. However now Mac's are becoming more popular because of their "style icon" status they are being targeted. This is especially the case because of “the Mac's don't get viruses” idea so few people bother to put any kind of security product on. (lots and lots of unprotected Macs to exploit)
For someone that has been using a PC from 1985 you seem to have done some somewhat dumb things. Firstly why kill the power to the PC just pull out the ethernet cable and if you still want to shut the PC down properly.
Symantec Anti-Virus Corporate Edition is just that it’s for a Corporate Environment that exists behind a dedicated HARDWARE firewall and runs through a Server! Not for your home PC, this is what NIS 2009 is for. In my job I often see laptops that have come in for repair with infections on that are running Corporate Edition that have been taken home (therefore outside of the secure Corporate Environment) where they are much more vulnerable. These laptops often pick up similar infections to the authors and it is a relatively simple (and a whole lot cheaper option) to press F8 start the computer in safe mode with networking and install various Free antispyware products like Spybot update them and clear the infection that way. The reason you couldn't clear the infection by taking the hard drive out and scanning it on another PC is Malware has got a lot smarter and if the infection isn’t active (i.e. running on the PC at the time) then most if not all security products are unable to detect it.
If the above didn't work then so long as this experienced user had backed up his data it would have taken approximately an hour or two at the most to format the drive and start again. Had you have been smarter still you could have either created your own recovery disks to restore the PC to how you like it with all of your software and settings installed(and then just had to put your personal files back on from your backup) or you could have restored from a Home Server image!

@annisman:

Slightly disagree with you on the "No excuse for using a Mac" as there are some very good media industry applications that only come on a Mac. For instance, a lot of high-end DVD and Blu-Ray production suites (such as DVD Studio Pro) only come on OSX. Now, Adobe Encore covers me 99% of the time but when I've had to use multiple camera angles and a lot of the DVD spec that goes unused, only DVD Studio has done it for me.

Autodesk Combustion and Apple Shake both give Adobe After Effects a serious run for its money in the motion graphics arena.

However, unless you are a high-level media professional and require such specific software (and therefore a Mac to run OSX legally) I entirely agree there's no real reason these days to go Mac unless you're "trendy" and have more money than brains.

I'd even disagree on the fashion statements given that the Sony Vaio range and even some of the new Dell custom case designs are directly more fashionable (with the labels to match) than a lump of aluminium.

@CrazySi:

I think you've hit the nail on the head and put the credibility of this entire article into question: a supposed power user of PCs with enough knowledge to run the claimed security setup wouldn't freak out and take such drastic measures just because they'd been infected with a spambot - that's what my mother does.

Furthermore, anybody who's been around a virus infection knows about proper antivirus tools (and therefore wouldn't even have Symantec or McAfee anywhere near their systems) and spyware removal.

Maybe the opening line of the article should read "I never had a good reason to admit to being a Mac user...until Jobs put his unibody aluminium penis in my mouth"

I had that once... I got a lot of emails that appeared that they came from my PC... then I found out that spammers tend to do that now... they spoof your own email. If spam looks like it's sent your your email then it usually gets past junk email and is harder to identify as junk. Looks like you formatted Windows for nothing! :(

I have to agree that ducking your head and running for a mac is a little hysterical when you computer gets a virus - most viruses are relatively easily removed with a little knowledge (ie a computer professional) While Apple computers do have some tangible advantages in ease of use, a lot has to be said for support in the rest of the world that is not serviced by a nearby mac store. For someone living in New Zealand (no we are not completely backward) it is not really a logical option to go for a piece of hardware supported only by 1% of technical staff. In most of the world Apple computers are sold at retail stores (similar to circuit-city, wal-mart) where there is little or no support, perhaps a tollfree number to tech support in india.
This should be a major factor in purchasing any hardware be it a LCD tv or a refrigerator.

I would like to have choice of screens, matte or shiny I personally find shiny annoying. I am not saving lives with my computer, I think it says somewhere on the licensing agreement not to save lives with computers!

I think a bunch of these comments are really thoughtless. I'm not a Mac fanboy, my main machine is not a mac. I have a Vista/7 Desktop, a XP laptop and netbook and an old eMac. At Work I admin about 30 PC's, mostly XP and a few Vista, and about 30 Macs, mostly iMacs. I know both systems relatively well.

Personally I prefer using a PC. I think PC's get a hard time in the press from people who dont really know what they are talking about. BUT, in many areas Macs are better, and it really irritates me when people say they are for fashion conscious idiots with too much money who dont know how to use a pc. Give me a break, anyone who has spent time (not five minutes at your buddies house) with Macs knows they are great machines for many/most applications.

Get an education or keep your mouth closed and listen. If you have something technical to add, for or against Macs or pc's then mention it. That is why I come to this site. If you think telling us macs are for girls then save it and tell your facebook buddies instead.

yeah , I have to agree , even tho I did have a pop at macs earlier on , osx is a very good os , it just lacks software support , and macs are easy , straight out of the box , as the ad goes , I think that although they are a little over priced they are very well designed , space saving and they hold their value better than p.c's . I use bootcamp and xp mainly because I can't run dragon naturally speaking on osx , but the fact that osx has such attention to detail that windows hasn't (such as better networking , not needing codecs etc) makes it a very attractive os . on the other hand I think windows is a deeper , more customizable os , they could both learn a thing off each other , windows 7 ,from what I,ve heard , borrows from osx leopard

I agree with other commenters. How can such a power user allow a single security breach to brick his PC? Makes no sense and he certainly doesn't get my respect.

Part of PC ownership is becoming educated in what not to do. Since most viruses written target Windows then the average PC user (hopefully) learns to not use Internet Exploder, maintain a good-quality antivirus/antispyware program and have a backup and restore strategy. Therefore I'd argue that when we see more viruses written for Macs the user community will have to learn good habits that competent PC users take for granted.

I don't view Macs as either better or worse, just different. Like anything, choosing a Mac or PC is a question of assessing the strengths and weaknesses and choosing what compromises you can live with.

If a user chooses Mac for reasons other than practicality then more power to them. Don't ask me for tech support, and don't drag me into Mac vs. PC conversations. I'd had my fill, thank you.

i'm fed up wid these MAC adverts (read reviews) .... and jus because his security failed him once , doesnt mean he has to run to mac ... so an "expert" as he calls himself , jus gives up after one attack ...

if u must know , i run my computer WITHOUT an anti-virus or any other fancy security software ... its still running GREAT ... and its not a MAC .... :P

I suppose you get these kind of comments when you post an article about Macs on a computer hardware site. I feel like anyone who reads these articles are hardcore PC enthusiasts. The responses to this article are just as fanatical as those from Mac fanboys responding to PC articles. Give it a rest. Use the system that works best for you. If someone wants to use something else, they're entitled to do so. Mark me down or whatever, just stop and realize that many of you sound as crazy as Mac fanboys.
