To SSD or NOT to SSD

Norm Beazer-3

Dumb question maybe.  I bought a LaCie 120 GB SSD Porsche Design drive, to use with my MacBook Air.  Love it.  Then months later I saw what I thought was a 500 GB version being advertised.  I had to buy it.  But was it a SSD ??  I think I misread the advert – the new drive looks identical to the the 120 GB SSD item, but I think it is actually an “ordinary” HDD – albeit nice and fast with USB 3.

Is there a way of confirming this more immediately, by “interrogating” the drive ??  

Disk Utility only yields the model number, which <yes> I can check against what is listed on the LaCie page.  As I say, I am happy with the purchase anyway.

I think that System Profiler will tell you.

Launch it from
/Applications/Utilities/System Information.app

Select
Hardware > USB

I think that if you drill down through the ports and attached devices you
will find a definitive description of the drive.

Bare drive 500GB SSDs are just now down to near $250. And they were $350
not too many months ago. How much did you pay?

Re: To SSD or NOT to SSD

Nello Lucchesi
I can see why you'd be confused:

http://www.lacie.com/products/product.htm?id=10609

Looks like the 500 GB option is a hard drive and the 120GB option is a SSD.

Much clearer on Amazon:

http://www.amazon.com/LaCie-Porsche-Design-External-9000304/dp/B00A3U8JV4

When you click the capacity button, the page refreshes and and makes it
clear whether it's a hard drive or SSD:

LaCie Porsche Design P'9223 Slim USB 3.0 120GB Solid State Drive (9000342)

vs.

LaCie Porsche Design P'9223 Slim USB 3.0 500GB External Hard Drive (9000304)

If it's connected to a Mac, you can "drill down" into it using the "System Information" app. Get a report and take a look at "Storage". Then look at "Medium Type". It will say SSD on SSD drives. If it's missing, it's a regular drive.

The 500Gb Porsche Design drive is a regular hard drive and not an SSD. The Porsche Design 120Gb is SSD and is actually more money than the 500Gb.

For Time Machine, a regular hard drive is more than fine. If you're using it for data access, you'll find the SSD much, much faster even on a USB3 connection. I have a WD My Passport Drive. The 2Tb is only $115 and the 1Tb is $70.

When I had my PalmPilot, I could hear it "hum" even though it had no hard drive or fan. The hum had convinced many people that the 512Kb device had to have a hard drive. After all, how could it have so much storage?

On the topic of the Subject. How many people are getting SSD drives for everyday work. I realize they are more expensive, but my concern is that many seem to need special drivers that need to be updated or even firmware updates. I worry about integrity if my data when I have to rely on yet another layer between my OS and my data. Comments?

Have experienced no such issues.  I have just replaced spindle drives with SSD, formatted them and used them.  Using current versions of OS X.

After a few MacMini and Laptop drive failures one office I consult with
of 20 people with about 30 Mac has been campaign to eliminate "spinning
rust". I was straighting up a couple of days ago and counted 18 SSD
drive boxes. And that wasn't all of them. (Some of the Mac Minis have 2
in them.) We have been proactive on the MacMinis that run things and
laptops. On iMacs we replace them as drives fail.

No drivers at all.

What I have not yet done but plan to do is enable TRIM on all of them
and also set the flag to no update the "file has been opened" log.

The only issue was with one MacBook Pro that was likely related to a bad
internal drive cable. Which was likely why the spinning drive was failing.

And we've migrating away from 2 XServes with attached XServe RAIDs in
this office to 2 MacMinis with attached Thunderbolt RAIDs that we're
filling with SSDs. Dramatic decrease in noise. :)

And I've done similar with him own stuff. We just put a 1TB SSD into my
daughter's MBPro. And I have several MacMinis with SSDs in them for my
home office.

I replaced the 750GB HDD in my MacBookPro with a 240GB OWC SSD, then moved the 750GB HDD to the DVD bay, using OWCs DataDoubler adapter. Then I combined them into a roll-your-own Fusion drive. It works GREAT!! I have the speed of an SSD, without having to worry about running out of space.

Could you please elaborate a little on setting the flag as you describe?

Thank you,

On the “Upgrading 2009 Mac Pro to SSD” thread last month, I narrated my installation of a new Samsung 840 Pro 256GB SSD on my Mac Pro. I mounted it on the Apricorn SATA-3 PCIe card. I’m absolutely delighted with it. The firmware card eliminated any worry about drivers or how to mount it in a spare drive bay. FWIW, in my research I never encountered any mention of drivers or driver issues.

If you were putting it in a MacBook Pro, you would simply replace the drive and clone your old boot drive from a copy, probably using Carbon Copy Cloner. Others have reported on successful SSD installations. Personally I am less worried about data loss on an SSD than an electro-mechanical “rotational” drive, but maintaining a current clone on a backup drive is a good idea anyway and obviates your concern about data integrity.

To SSD or NOT to SSD

Norm Beazer-3
In reply to this post by Norm Beazer-3
Thanks to everyone who responded so quickly.

After penning my enquiry, I remembered I had a copy of DriveDX in my Applications folder.  I fired it up this morning, and DDX promptly confirmed confirmed everything I wanted to know, including that the SSD was a Crucial M4.  

Also told me that the SSD needed a firmware update, and spelt out for me the expected failure mode if I sat back and did nothing – after some 5000 hours of operation, that is.   So I shall have to research how to go about that some time.  Not sure how and when I would have found out about this without DDX, but there is plenty of time for me to upgrade.

Otherwise, as several have pointed out, delving into Utilities / System Information.app will yield the information after a fashion (SSD advised, else HDD assumed by default).

Just so everyone knows, you can get there via the "About This Mac" under
the Apple Menu.

Click on "More Info" then click on "System Report"

Look at this blog post. It has most of the things you MIGHT want to do
with an HDD to SSD swap.

http://blog.alutam.com/2012/04/01/optimizing-macos-x-lion-for-ssd

#noatime and TRIM are the two I'm thinking of. Some of his other ideas
are a bit over the top in my opinion but to each his own.

No warranties, expressed or implied. :)

Hold down the option key while clicking on the Apple menu and the first item is System Information… Saves a click or two.

Make sure you check with the manufacturer before you do as not all recommend it's use.

Users just logically assume that solid state hard drives are more reliable than traditional rotating platter hard drives.  However, everything that I've read indicates that they fail at just about the same rate, and, even worse, they tend to give less warning of impending failure, and once they fail they are much more difficult to recover data from.

Over the years I've come to the conclusion that "recovery" is a loosing
game. Storage is cheap. Back it up. Duplicate it. Whatever.

Don't crawl over dollars to save pennies.
