Drive sleep for SSD?

I have a solid state drive in my MBP and had read that they perform better when you do not allow the computer to put the drive to sleep.
Can someone validate this for me or let me know if there is a better or worse way to manage the SSD in my MBP?
thanks in advance
Marc

In reality, hard drive sleeping almost never happens when a machine is powered on. There is almost always some level of disk access which prevents the drive from sleeping. Having said that, all sleeping a hard drive does is power down the spindle to conserve some power. I don't really believe it saves on any wear and tear as constantly starting and stopping is more wear than just running continuously. There is no benefit to sleeping an SSD as there are no platters to spin down.

TD340 3.5" to 2.5" drive adapter for SSD

I'm looking for a proper 3.5" to 2.5" drive adapter in order to install a couple 2.5" SSDs into my TD340 server with 8x3.5" bays. I just spent a solid 30+ min. on the phone with Lenovo, got transferred literally 8 times to other departments (some twice) and got absolutely nowhere.
I simply need an appropriate drive adapter that will orient the SSD so it will align properly with the backplane once I install the drive into the adapter and then into the drive tray.
Can anyone please please please answer this seemingly simple question and point me to an adapter.
Thanks,
Kevin
Solved!
Go to Solution.

Thank you for replying again Nivek but that answer is not valid at least for me, no offense.
I would have been happy to buy engineered/designed Lenovo supported hardware to fulfill my needs but instead I had to track it down elsewhere. I'm know for a fact I'm not the only person with this need based on my research for this solution. As there are probably tens of thousands of servers sold with 3.5" backplanes is it not expected by Lenovo that some of those customers at some point might want to use drives such as SSD's as capacities increase in the future? So what are they supposed to do, swap out those 3.5" backplanes for 2.5" ones and then have to replace all of their drives as well? I think not.
I just think Lenovo is just missing an opportunity to further help it's customers is all. Again, no offense to you but your answer is not a valid solution.
Thanks,

Better to use optical bay or drive bay for SSD?

Just bought a mid-2012 MacPro. Also purchased a Crucial 512GB SSD drive, which I intend to use for a boot drive. I know that I can install the drive in one of the four slide out drive bays. From what I can gather, it doesn't matter which bay I use, Mac will boot equally well from any of them. My question is: What about the second optical bay? Is there any advantage to putting the SSD there? (other than keeping another slot open for HDD?) Have tried to research this a bit, but the model is brand-new, not a lot of info out there.. Mucho thanks!

The model is not "new" it is just a tiny change in processor options, everything else is unchanged.
To use in standard bays you need to use an adapter to fit. If you put it in the optical bay if you are like me, it will get moved, put on its side, so again, might want to 'tie it down."
But it doesn't matter which location.
With 512GB you probably are going to use it for much more than just the boot drive. Maybe Aperture or other libraries.
As for research, there are products and reviews and Mac centric sites such as

Hard drive sleep for selective drives?

Thanks the the community here I earlier this week we solved a problem with my Time Machine back ups-- seems as though I had the Energy Saver Preference set to spin down the drives. Once I unchecked that the TM is working great.
However, In my MBP I've got an SSD as the boot and main drive, but I also have a regular HD (in the optical bay) That HD just has itunes and some movies on it, little used stuff. So... is there a way (a utility or something) to have the internal HD spin down (since it is not used much), but have my external drive that I use for TM set to not spin down?
Thanks

AFAIK, the
pmset disksleep
command only really applies to the startup disk. What power management rules your other drives follow depends very much on their firmware. Some drives will ignore pmset commands (if they're not the startup drive) and others may be manipulated through the vendors firmware.
The best thing you can do is contact the manufacturer or supplier of your HD and ask them for details.

P55-GD65 - SATA port and driver installs for SSD ?

Please can anyone help...
I have a MSI P55-GD65 mb (AMI BIOS v1.2/012.020.000.015) and am about to do a clean install of Win 7 64 bit onto an unused Crucial M4 SSD (firmware rev 010G). After disconnecting my existing HDD from SATA1.....
Q1 Should I update the mb BIOS? I currently have no probs....if it aint broke....
Q2 Which SATA port should I connect the SSD to?
   SATA 1-6 ports are Intel P55, SATA7 is supported by JMicron JMB363
Assuming the next steps are:
   plug CD/DVD drive into SATA 4
   boot into the BIOS, enable AHCI and set the SSD as the primary boot drive after the CD/DVD drive
   boot from the Windows 7 disc and install the OS,
Q3What do I do about installing drivers?
Allow any default drivers to install from Win7, then install drivers from the mb disc (starting with chipset drivers), then update them with the latest from MSI. Or what?
I understand that rebooting after installing each driver (and the updates) is a good idea (NickN from SimForums), but this suggests a lot of reboots !
If some reboots can be left till several drivers are in, at which points should reboots be done if there are 5 or 6 drivers+updates to install? I wouldn't be bothering with any RAID configuration or the floppy drivers.
Finally..
Q4 At what point do I perform the firmware update of the Crucial SSD (to rev 040H) ? I'm assuming a driver install will be required for this.
Thanks

If all is well don't do anything.

SATA 1-6 ports are Intel P55, SATA7 is supported by JMicron JMB363
All of the ports are SATA II, so any port 1-6 would be fine. I suggest port 1 or the purchase of a sata III card. IE:
http://www.amazon.com/SIIG-SATA-6Gb-2-Port-PCIe/dp/B006Q4MGOM/ref=sr_1_3?s=electronics&ie=UTF8&qid=1368545006&sr=1-3&keywords=sata+iii+card
Although I won't make a huge amount of difference.

I leave the internet disconnected until I have loaded all of the drivers. I also generally do an F6 installation with the most recent AHCI / Raid drivers available if applicable.
Once all of the drivers are install, I connect the internet and let it update.

If there is a firmware update available, the best thing to do would be to install the ssd in another computer, update the firmware, then place it in your computer. (or keep the existing hdd in for a moment to do this)
Data loss is very possible during an ssd firmware update.

Gtech drives sleeping for no apparent reason

I have 3 Gtech FW800 drives chained together via my MacBook Pro FW800 bus. Gtech says it is fine to chain 5 together.
I have UN-chcked the box in System Prefs > Energy Saver > "put hard drives to sleep when possible". And yet, my Gtech drives fall asleep after roughly 15 minutes of down time. They are then very slow to spin back up and I get the dreaded pinwheel. This makes me nervous.
Time Machine is OFF.
I also have 2 FW400 drives and they *never* spin down.
Anyone else experiencing this with Gtech FW800 drives - purchased at an Apple Store?
Any solutions?
Should I switch to another brand of FW800 drive?
thanks

Via a post on DigiDesign's ProTools forum, I have determined that G-tech drives are NOT at all happy with ProTools. Hence I will be getting rid of these drives.

Swapping optical drive for SSD - How to set it up?

I'm going to purchase a Crucial M4 128GB SSD for my Late 2011 13" i7 Macbook Pro. I don't use my optical drive at all, so I figure I may as well swap that out for my current 750GB HDD, and put the SSD in the main harddrive bay. I know full well how to physically install the respective drives, but my confusion comes when cloning the current HD onto the SSD, then moving all your media files (music, movies, documents etc) over to the HD, while keeping your system files and applications on the SSD.
So what I really need, is a PROPER in depth guide from the start of the setup process (First boot after installation of physical drives) detailing how to copy my system files and applications over to the SSD so I can boot from it, while keeping my data & media files on the HD and being able to access them all as I normally would through finder.
Any and all responses are appreciated - I need all the advice i can get!

If you use a cloning software program it will move, actually copy, everything from your original drive to the SSD.
No need to anything after that to get the SSD to boot and have all your programs and data.

Disable disk sleep for specific drive?

My Mac Pro is running 24/7 with sleep enabled.
Hard disks are set to sleep, when possible. One of my SSDs is on an internal PCIe card. With disk sleep enabled, it does not come up quickly enough and the computer keeps thinking, it was ejected. The problem goes away, when disabling disk sleep.
No sleep is no problem with SSDs, but there are some spinning 4TB disks on the system only used infrequently, so I would like to let them sleep.
Is there a way to disable sleep for a specific disk only?
-- Harald

Hi BahaSs,
It generally is safe to "Enable write caching on disk" unless you are dealing with broken applications which are not using
FILE_FLAG_WRITE_THROUGH but need every write to be persistent. Disabling this would not hurt too much. It's really not recommend "Enable advanced performance" or
"Turn off Windows write-cache buffer flushing on the device" on a system where you value uptime or require data integrity.

Swapping out optical drive for SSD

Early 2011, 15" Macbook Pro with Mavericks 9.1
So basically, I want to replace my optical drive with an SSD. Seen a few discussions on it, know basically how it works, am aware of the warranty voiding issue, and also aware of how people at apple who made my computer are 12034725801x smarter than me and I shouldn't do it. I'm gonna do it anyway.
What are the best brands for the superdrive slot to hold the second drive, and should I leave the HDD in the primary slot or move it to the secondary?
The first one is the main question. I've read that only the primary can boot, and if that's true, then it would have to be the SSD for sure. Confirmation would be nice.

Get the OWC DataDoubler bracket for your model. The SSD should replace the HDD. The HDD goes where the optical drive is located. What you need to do:
How to replace or upgrade a drive in a laptop
Step One: Repair the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Step Two: Remove the old drive and install the new drive. Place the old drive in an external USB enclosure. You can buy one at OWC who is also a good vendor for drives.
Step Three: Boot from the external drive. Restart the computer and after the chime press and hold down the OPTION key until the boot manager appears. Select the icon for the external drive then click on the downward pointing arrow button.
Step Four: New Hard Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your new hard drive (this is the entry with the
      mfgr.'s ID and size) from the left side list. Note the SMART status of
      the drive in DU's status area. If it does not say "Verified" then the drive
      is failing or has failed and will need replacing. Otherwise, click on the
      Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from
      the drop down menu to one. Set the format type to Mac OS Extended
      (Journaled.) Click on the Options button, set the partition scheme to
      GUID then click on the OK button. Click on the Partition button and
      wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the
      drive entry) from the left side list. Click on the Erase tab in the DU main
      window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the
      Options button, check the button for Zero Data and click on OK to
      return to the Erase window.
6. Click on the Erase button. The format process can take up to several
      hours depending upon the drive size.
Step Five: Clone the old drive to the new drive
1. Open Disk Utility from the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Check the box labeled Erase destination.
5. Select the destination volume from the left side list and drag it to the
      Destination entry field.
6. Select the source volume from the left side list and drag it to the
      Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the new internal drive. Source means the old external drive.
Step Six: Open the Startup Disk preferences and select the new internal volume. Click on the Restart button. You should boot from the new drive. Eject the external drive and disconnect it from the computer.
If you wish to use your Home folder on the HDD instead of on the SSD:
How to use an SSD with your HDD
If you are going to use an SSD as a boot drive together with your existing HDD as the "data" drive, here's what you can do.
After installing the SSD you will need to partition and format the SSD using Disk Utility. Then, install OS X on the SSD. After OS X has been installed boot from the SSD. Use Startup Disk preferences to set the SSD as the startup volume.
Open Users & Groups preferences. Click on the lock icon and authenticate. CTRL- or RIGHT-click on your user account listing in the sidebar and select Advanced Options from the context menu.
You will see a field labeled "Home dir:" At the right end you will see a Change button. Click on it. In the file dialog locate the Home folder now located on the HDD (HDD/Users/account_name/.) Select the folder, click on Open button. Restart the computer as directed.
When the computer boots up it will now be using the Home folder located on the HDD.
Another more technical method involving the Terminal and aliases is discussed in depth here: Using OS X with an SSD plus HDD setup - Matt Gemmell. This is my preferred approach because I can select which of the Home's folders I want on the HDD and which I don't want. For example, I like to keep the Documents and Library folders on the SSD because I access their content frequently.
Be sure you retain the fully bootable system on your HDD in case you ever need it.

Swapping OPtical Drive for SSD

I am going to swap my optical drive for an SSD to make everything far more faster. My computer is out of warranty so it won't be affected. I was just wondering what will happen to my existing hard drive when I clone the old hard drive and copy it on to the SSD? Obviously I will make it so my computer boots my SSD, does my old hard drive act in the same way an external hard drive does? Will I be able to save things on there just as easily as before?
Thanks

Go talk to Bmer over here
http://macosg.com/
What he did was move the hard drive to the optical bay and then replaced the boot drive with a SSD with a kit, he can walk you though it all as he's good with SSD's and all it's headaches. The kit also makes the Superdrive a external optical drive.
SSD's make good boot and program drives, but not a good file drive, use the hard drive for that instead.
One of the drawbacks is you can't boot from the OS X install disks or Windows disk or even perhaps not even Linux disks on a external optical drive.
So you'll have to learn all about Carbon Copy Cloner and option bootable clones too.
Download the free MacTracker and find out your SATA, as that can limit your SSD speed and could save you money as you buy the slower older SATA SSD's to match your hardware instead of the higher more expensive ones you can't use anyway.
Good Luck.

How do I change the install drive default for Creative Cloud Suite? I have a 64 gb SSD drive as dri

I bought another 128 GB SSD drive just for the Adobe applications. I can't figure how to change the download destination as it download or before it installs. What am I missing here?

I am sorry Scottcommercialrealtor I missed the fact you were installing Creative Cloud, we have had a lot of traffic with the release of CS6 and Creative Cloud, you can only customize the install location for Creative Cloud. You can do so by clicking on your name in the Adobe Application Manager and selecting preferences. The install files will have to be downloaded to your OS volume but you can choose to install many of the components of the applications on a separate drive. The shared components though will also need to be installed on your OS volume.
SSD solutions I would honestly recommend having your OS and Apps installed on the same drive so you can maximize your performance. You can then use a standard hard drive for your documents, videos, and images. You mentioned that you purchased a 128 gig SSD. You might consider cloning the 64 gig drive over to the 128 and then having your OS and Apps installed on the same drive.

UBS 3.0 Drive Missing from Windows Explorer after Drive Sleeps

I have an external USB 3.0 Hard drive that is present when the computer first starts up but is missing when the drive sleeps. I have to restart the computer to see the drive again. Is there a driver update or setting that I'm missing?
HP ENVY Phoenix 810-135qe.

Hi,
Your issue description seems to indicate that either your device has an issue and/or PC default settings have been changed.
Check the USB drive manufacturer owner's manual for PC power recommendations. Additonally, check with the manufacturer to see if there are known issues with the drive when the PC goes into a sleep state.
Go into the Control Panel ---> Power Options and reset the Plan settings back to the defaults and save. Now reboot and see what happens when you PC goes to sleep.
Look in Device Manager under USB controller and view the Power Management settings for the USB 3.0 hubs. You might need to uncheck the default setting to save power.
If the above suggestions don't work then perhaps a BIOS setting is corrupted. Clearing the CMOS will bring the BIOS settings back to the factory defaults.

Make External Drive Sleep?

New Macbook Pro with Mountain Lion, which spends most nights plugged in, with an external drive attached for Time Machine backup.
My former backup drive, a Seagate Freeagent Go, would go to sleep whenever my laptop was asleep, or when ejected. When the computer woke up, the drive did too and all was well (unlike the problems a few users seem to have had with drives not waking).
I recently installed a 512GB Crucial SSD (MS PowerPoint opens in about 1 second!), and moved the TOSHIBA MK7559 750 GB drive that came inside the Macbook Pro to an external USB3 case, so that I would have a bigger backup capacity. It works very well for backup, but the drive keeps spinning even if the computer is asleep, and even after being ejected. The check box in Energy Saver Prefs is checked to allow drives to sleep when possible.
It is almost certain that problem is with the drive case's firmware, not with my Mac or the OS. What I am looking for is a workaround. Is anyone aware of any utilities that might let me force it to spin down? I am concerned about the long term reliability of the drive if it keeps running 24 hours a day.

Most of the time this feature is built into the Drive Enclosure and has nothing to do with the operating system running the computer.
So it would seem the enclosure you have does not support such a feature.

Put HDD to sleep with SSD

Hello,
I have a question for SSD users. I have a late 2008 unibody macbook pro. I just installed effortlessly an OCZ vertex 2 120gb ssd. Love the speed! I read around the internet that you should not check put hdds to sleep under energy saver for ssds. Is this true? My question would be the following:
I also heard that OCZ has some garbage collection algorythm that makes up for Mac's lack of TRIM support. If I put hdds to sleep when possible does it mean that the garbage collection will not work? What is the advantage of NOT putting hdds to sleep with SSD?
Finally, I am planning to install a second hd instead of my superdrive, a normal hd that is (seagate xt 7200). I suppose that having it means I should put the hdds to sleep when possible, am I right?
In case I should not put to sleep the ssd, can I select two different settings for the two different drives?
Sorry if this sounds confusionary, it sounded a lot better in my mind...
Thanks for any tips!

I also heard that OCZ has some garbage collection algorythm that makes up for Mac's lack of TRIM support.
I dont think garbage collection (and over provisioning) makes up for lack of TRIM support, but certainly helps it in that direction.
If I put hdds to sleep when possible does it mean that the garbage collection will not work? What is the advantage of NOT putting hdds to sleep with SSD?
I think you are asking - "If I put ssds to sleep when possible does it mean that the garbage collection will not work?", since hdds don't have the garbage collection.
Well, from (http://www.ocztechnology.com/aboutocz/news/151) and (http://www.enterprisestorageforum.com/technology/features/article.php/3850436) it seems that, according to OCZ's Chang, some of their ssds use idle time garbage collection. If yours came with a spec manual, I would look there.
The way Chang puts it is:
+OCZ's goal is to keep SSD performance at peak levels over the drive's lifespan. OCZ, he said, uses two basic garbage collection methods: incorporating the maintenance within firmware, and providing user-initiated tools to accomplish the same task. OCZ provides three different garbage collection methods, said Chang.Some OCZ drives feature idle-time garbage collection in the firmware, including PCI-Express and high-capacity 3.5-inch SSDs, which aim for high-performance endurance. OCZ's mainstream 2.5-inch SSD solutions ship with TRIM support, which is enabled on Windows 7 and various Linux versions.+
+For users who prefer Windows XP or Vista, OCZ provides a manual garbage collection tool that can be initiated at the user's discretion, said Chang, noting that the company also provides a garbage collection upgrade firmware for XP and Vista systems. "Garbage collection is just one more tool in OCZ's feature sets that helps sustain the revolutionary performance of SSDs over the long term," said Chang.+
So, if yours uses the idle time, it may need not benefit from a nap, although I can not find anywhere that suggest how long idle time is.
I find the whole OCZ presentation rather sloppy. I am sure they have good drives, but after reading on OCZ, it makes me want to take a nap.
