SSD SMS?? (Solid State Drive Sudden Motion Sensor)

Just a quick question, can anyone tell me if the SSD option has a sudden motion sensor? I realize the benefits to hard drive health wouldn't be needed in a SSD but I find it extremely useful for security (ie: iAlertU).
Thanks!
SAM

Yes it does. This is from my SSD model:

Second Hard Drive, Sudden Motion Sensor

Back in the fall I put a SSD in my 2007 MacBook Pro. It's working perfectly. I found the "OptiBay" product, which basically replaces your optical drive with an adapter for another hard drive. I haven't received it yet, but when I do I plan on installing it with a traditional hard drive. My question regards the sudden motion sensor (SMS). I disabled it because it's not needed for the SSD, but I was planning on re-enabling it for my secondary that I will be installing. I'm still going to boot off the SSD, though. Is there a way, or terminal code, to assign the SMS to a certain disk? I'm assuming it will just disable the root drive in the event of "sudden motion," but would this affect a secondary drive?
I'd love for there to be an option to change the identifier, from disk0s2 to disk0s3, but I have a feeling it isn't possible or would be infinitely more difficult... thanks.

Most drives are available with the equivalent of an internal SMS. You just have to check the specs. Drive manufacturers often offer two versions of their drives... one with and one without a SMS. If you get a drive with the SMS built in, you can just leave the MacBook's internal one disabled.
Here is an example of one of the most popular drives:
http://www.seagate.com/www/en-us/products/laptops/momentus/momentus5400.6g/
Seagate's SMS technology is referred to as G-Force. Note the product number: 5400.6_g. The "g" denotes the drive has a "G-Force" sensor.

What are the benefits of solid state drives for an iMac

I am thinking of getting a new iMac and would like to know the whys and wherefores of a solid state drive, please. The one that is sold with the iMac is 250 gig. Does that mean it's storage capacity is lower than a normal 1TB hard drive?
The views of anybody who has one would be welcome.
Thanks in anticipation.
Jim (West Riding)

The one that is sold with the iMac is 250 gig. Does that mean it's storage capacity is lower than a normal 1TB hard drive?
Yes! But you can access the stuff faster and of course boot faster. They are quiet, run cool, and have low power consumption.

Should I disable the sudden motion sensor after upgrading to an SSD

I put a 1TB Samsung 840 EVO in my MacBook Pro (9,1). Should I disable the sudden motion sensor? Does it do anything else other than park the hard disk (like something with the fans)?

You may want to read up on the SMS here:
Mac notebooks: About the Sudden Motion Sensor
Sounds like you can safely disable it if you wish since MacBooks which ship with an SSD drive seem to have it disabled.

Hard drive upgrade on 13" MBP sudden motion sensor compatibility

Hello,
I'm planning on upgrading the hard drive in my 13" MBP (aluminium unibody) and I've read a lot of posts regarding the sudden motion sensor conflicts with OS X 10.6.2. I'd like to know if the Western Digital 500GB Scorpio Blue here (http://www.dabs.com/products/western-digital-500gb-scorpio-blue-5400rpm-sata-300 -8mb-58P6.html) would suffer from the conflict (I'm not sure if "Shock Guard" = sudden motion sensor). I don't know if its a simple yes/no or whether its drive / mac specific.
If it would be a problem does anyone have a suggestion for a guaranteed compatible 500Gb hard drive (5400 rpm is fine)?
Any thoughts are much appreciated, thanks for your help!

Western Digital Lists their drive features as:
* IntelliSeek™ - IntelliSeek technology calculates optimum seek speeds to lower power consumption, noise and vibration.
* SecurePark™ - WD's SecurePark technology parks the recording heads off the disk surface during spin up, spin down and when the drive is off. This ensures the recording head never touches the disk surface resulting in improved long term reliability due to less head wear, and improved shock tolerance.
* ShockGuard™ - WD's ShockGuard technology protects the drive mechanics and platter surfaces from shocks during shipping and handling and in daily operation.
* Free-fall Sensor - As an added layer of protection, if the drive (or the system it's in) is dropped while in use, WD's free-fall sensor detects that the drive is falling and, in less than 200 milliseconds, parks the head off the disks to help prevent damage and data loss.
* WhisperDrive™ - WD's exclusive WhisperDrive technology combines state-of-the-art seeking algorithms that result in one of the quietest 2.5-inch drives on the market.
The Free Fall Sensor is the equivalent of the Sudden Motion Sensor. Looking at the specs for the drive you linked to... they list the following features:
Shock Guard, WhisperDrive, SecurePark
As they do not list Free Fall Sensor, I'm guessing this model does not have one so it should not conflict with the internal Sudden Motion Sensor in your MacBook.

Drive Upgrade: Sudden Motion Sensor & SMART

Greetings,
I have a couple of technical questions regarding a Hitachi HD upgrade I am planning. I purchased the 5K500.B from Other World Computing (OWC) and had some concerns with the Apple Drive Utility when I went to format it.
I also purchased an external enclosure that I can mount my old drive in after I replace it. When I went to format the new drive (in the external enclosure) with Drive Utility, I noticed some differences between the old drive and the new drive. The original drive is a Hitachi 200 GB 7200 RPM which Apple supplied as an option. I will list my MacBook Pro information after this section. My questions are:
1) SMART status reads "Unsupported" on the new drive and "Verified" on the old drive. OWC said this is because SMART only works on internal drives and SMART will work after I install the new drive. I just want to check the accuracy of this statement.
2) My MacBook Pro has a Sudden Motion Sensor for drop protection. Is that built into the laptop or the hard drive? Will Apple's drop protection work with the new drive?
3) Is the 5K500.B really a direct replacement with all the functionality of the original drive.

I read in one of your posts that the sudden motion sensor can be easily disabled. Could you please tell me how?
I can be online, or not, and the crazy spinning colored disc starts to spin, then if I pick it up and set it back down usually it stops and the macbook (4,1) continues with it's work. I guess that it is the sudden motion sensor although I could be wrong...Just seems strange that it normally stops when i pick it up, tap it, gently, etc.
Could you please advise? It shows enabled in 'about this mac' but I can't find anyplace to dis-able it.
It's almost impossible to stream video, although that may be from something else.

Sudden Motion Sensor and WD Scorpio drives

I'm researching the 13-inch MacBook pro. I stumbled on this thread: http://discussions.apple.com/thread.jspa?threadID=683913 which says that the Sudden Motion Sensor in Apple portables have issues with kernel panics when you use Western Digital's Scorpio line of hard drives. I was wondering:
- Is there a way you can disable SMS in System Preferences?
- If I get WD's Scorpio drive without their implementation of SMS ("free-fall sensor"), will Apple's SMS take over without KPs? Or do I have to use a stock drive?
Thanks!

Also, the application Cocktail can disable SMS by disabling it and without venturing into the Terminal.

Sudden Motion Sensor crash in MBP with SSD

Hi. I replaced my 2011 17" MBP's internal HD with one, then another SSD from OWC, going from 240 to 480.
As indicated in OWC's instructions, the Sudden Motion Sensor no longer applies and should be disabled with this command from the terminal:
$ sudo pmset -a sms 0
And using this command, we can see that the SMS is off:
$ sudo pmset -g
Active Profiles:
Battery Power                    -1
AC Power                    -1*
Currently in use:
womp                    1
halfdim          1
sms                    0
What happens all too often though is that my Mac issues an SMS crash while asleep if I am driving home and hit a bump in my car. Just Monday, I was driving with my Mac open and on, the car hit a bump and I got to watch the Gray Screen of Death as the Mac issued a kernel panic from the Sudden Motion Sensor.
But it's off.
FYI, I turned it off to try and stop this behaviour

Sudden Motion Sensor and a new hard drive?

I was just wondering if the Sudden Motion Sensor will still work with a non-Apple hard drive.
If so,
I am also looking for a 160GB hard drive replacement for the Macbook. Something fast, reliable, quite, and most important, good quality. And low power consumption, if possible
P.S. I am also looking for 2GB RAM, with the same qualities.
Thanks.

Nick,
oddly enough there have been reports of the SMS not working properly with some Western Digital drives, which have their own SMS system as well. I happen to have a 120G WD Scorpio, but haven't seen the problem myself yet. I'm sure OWC will replace it without problems if it crops up though-one advantage to dealing with a Mac specific dealer

Can I use a solid state drive (SSD) with a G4 1 GHz powerbook? If so, how do I do it?

Hi:
Can I use a solid state drive (SSD) with a G4 1 GHz powerbook? If so, how do I do it? Thanks.
fromx001

fromx001 I believe you can use a SSD as internal drive, of course make sure to buy an ide/ata. There are all sorts of sizes up to 480 GB also in the ide/ata standard. You should however research carefully your purchase, as the performances of your SSD are going to have to rely on firmware "garbage collection", as the older operating systems haven't been written with SSD in mind.
Mac Man JW: some people depend on Classic as a brody said, other people need a phone modem from time to time, other people use the laptop in harsh environments, and at -15C and below, LCD screens easily crack and break; NOT the powerbook which has hot air towards the screen (and it's a machine that heats quite a lot). My alu Powerbook 12", which was *not* treated with velvet gloves, only once had a cracked screen: a cleaning lady had stepped over it (!!!!) no joke. And in normal / light use today, it is still pretty decent and usable.

My HP Pavilion Notebook can support a solid-state drive (SSD) (also known as a solid-state disk)

Hi,
Product Name dv6-6093ex
Product Number LM610EA
I don't know if my HP laptop can support a solid-state drive (SSD) (also known as a solid-state disk or not.

Thanks a lot,
I really checked out the prices of SSD at amazon.com
However, I found that the prices were relatively expensive.
120 GB
$88.49
250 GB
$132.00
500 GB
$231.99
1 TB
$439.95
Do you think it is worth purchasing SSD? Did you find any noticeable benefits since 439.95 dollars would let me purchase another laptop

Setting Up SSD Solid State Drive for Cache...Help!

Hello,
I am trying to configure my system to do really heavy special effects using After Effects and other programs. I bought a new computer with specs below and a Solid State Drive for the cache as recommended in the White Papers. I plug the SSD into a port on top of the machine. I must have it configured wrong because I keep getting the message "disk cache folder cannot be the root of a volume." I don't know how to configure this correctly so my work will use the SSD properly. Can someone walk me through this?

Solid State Drive (SSD) on MacBook Pro unibody (and fast hard drives)

I've reviewed the 80GB Intel X25-M solid state drive (SSD), along with the Hitachi 320GB Travelstar 7K320, Seagate 320GB Momentus 7200.3, Western Digital 320GB Scorpio Black and Western Digital 500GB Scorpio Blue.
All of these are great drives for the MBP, but the X25-M really screams for anything with reads, and writes are quite respectable.
http://macperformanceguide.com/Reviews-SSD.html

German computer-magazine CT tested SSD drives recently, rating only Intel-SSD's as "faster and more energy-efficient under all circumstances". They are definitely not all the same...

Solid State Drive (SSD) on Recent Mac Book Pro

I bought a non-retina 15 inch MacBook Pro in late August / early September, with a 1 TB hard drive. Originally my intent was for the largest hard drive so I could keep my itunes music libarary (Approximatley 60 GB) on there. I've only used about 115 GB (xcode and a few macstore apps, and a lot of ios apps).
Recently, I've been getting paranoid about hard drive crashes due to it being a traditional drive rather than a Solid State Drive (SSD), (Thank you very much Phil Schiller), because I expect my storage level to stay at its existing level for sometime, I was considering swapping it out my existing 1 TB for a SSD. I'm assuming this can be done on a MBP, right?
Is it even worth the effort, or am I needlessly worrying?
Like I said, I bought it in late August / early September at the earliest, so the warranty is still in effect. I'm assuming swapping the drives would void the warranty. What if I took it into an apple store, and had them do the swap? Would it still void the warranty, or would it remain in effect.
Any thoughts?
Anybody from Apple or AppleCare have any thoughts or insight?
-Jeff

Apologies. I probably should have checked the link I sent you. I narrowed it down to 3 choices (Direct links below)
http://www.crucial.com/store/partspecs.aspx?IMODULE=CT512M4SSD2
http://www.crucial.com/store/partspecs.aspx?IMODULE=CT512M4SSD2BAA
http://www.crucial.com/store/partspecs.aspx?IMODULE=CT512M4SSD2CCA
I didn't see anything about a transfer kit (or external drive dock) from your original post, or anything 3.5 inch adapter bracket. So your last post helps clarify things.
I'm assuming because I don't have an external drive dock, I should just go with the transfer kit, RIght?
At this point, due to the level of complexity, I'm thinking it may be easier to just take it in to the apple store and have them do it.
Do you know if they do this?
I'm sure if they do, they charge a premium, but even if its only $100 + cost of the drive, it would be worth it, not to have to deal with it myself.
Thanks,
Jeff
