Apple Does it again SATA 1.5 in a 2010 i7 MBP 15!

And the bottle neck in your system? That 7200RPM drive.

 

Doesn't this just mean, the interface negotiated with the HDD, that S-ATA 1.5Gbps would suffice?

My 2007 Aluminium iMac shows this:



I'm confused, but the 1.5Gbps are still more than efficient with its 148MB/s

 

The chipset is fine - it's the drives they are shipping that negotiates the 1.5Gbps link speed. Look at mine with a Samsung 3.0Gbps drive. My Seagate 7200K 500 is only 1.5...

The 2.5" drive is not fast enough to max out the 1.5 so I'm OK with the shipping drive not being 3.0.

 

My 320GB 7.2K RPM Seagate drive shows this...granted my MBP is an early 09 model so this probably doesn't help you. Like others have said the drive will never saturate the bus so its all good anyway.

 

Mine is 3 gigabits negotiated on an i5 2.4 mid 2010.

 

Intel G2 Postville in my new i5:

 

Its just some of the drives they use people!

Shame how its kinda funny I buy the i7 2.66 AG, and I get a 1.5 drive

What Id like to know, straight from Toshiba's website:
Further design optimizations boost the durability of the MKxx55GSX line-up, providing industry-leading robustness against shock while the drives are in operation. An operational free-fall sensor (FFS) feature further protects the drive and user data against potential damage from shock, vibration and rough handling. The MKxx55GSX products support a 3 Gb/sec data transfer rate and have passed testing by the Serial ATA International Organization (SATA-IO) for SATA interoperability.

WTF

 

It doesn't matter; if your drive needs SATA 3Gb/s it will negotiate it.

 

Youre right it doesnt matter, but if the drive is SATA30 and the computer is, it should be so, period. Im wondering if Apple has a custom firmware on the Toshiba.

I could really care less, since none of these drives can even touch SATA 150

Nice join date alphaod, haha

 

The "negotiated" speed is a new form they added; so if this was ever an issue before we would not know as it was not viewable previously.

So it's possible the Macs have had this phenomenon for a while, just that no one could tell.

 

1.5 gbps probably lets them save a little power.

 

I will try my stock 320gb HDD I am using my own 500gb HDD.

 

Which macs?

The first gen non unibooty mac has a 1.5Gbps bus even when using an SSD (I should know )

Then the unibooty ones brought 1.5Gbps, in which everyone on the boards freaked the heck out. The firmware update resolved that issue.

But yes, the latest MBP will negotiate whatever speed is necessary.

 

2010 i7 17" shows 3 Gigabit for both my SSD and my ExpressCard SSD. Only the Superdrive is 1.5 Gigabit.

 

i'm showing 3.0. i swapped the stock 5400rpm drive with a new hitachi 320gb 7200rpm drive and converted the stock drive to a time machine backup disk.

 

My SSD shows 3. However, the super drive is 1.5

but what ever...my superdrive will never use up that 1.5G...lol

btw...I have the 2010 MPB i7. 15"

 

the link speed is the bandwidth limit of the actual connection
the negotiated speed is the actual connection speed and determined by the attached drive.

Most 5400 and even some 7200 will connect at 1.5 while SSD drives will typically connect at 3.0

So to make it even more clear, if your negotiated connection says 1.5 but you later replace that drive with say an SSD that connects at 3.0 than your negotiated speed with say 3.0

 

Exactly. No issues here.

So heres my question/issue with all this guys:

If OSX now auto negotiates based on hard-drive need, and I have a SATA300 Hard drive as stated by specs on TOshiba site (note this is the stock APple HD), then why isnt it kicking to 300? Does apple load custom firmwares?

 

I had an SSD in my MacBook, at that time it was 3Gbps (even posted a screenshot here at some poing). Now there's an HDD there, and it's 1,5Gbps. As long as the SSD I'm getting now (Intel X-25M Gen2) negotiates at 3Gbps, I'm happy.

 

I use multiple VMs in Virtualbox and went with a ST9500420AS 7200 RPM drive and made sure it was a SATA 3 GB drive. I'm kind of shocked Apple would ship a new MBP with a 1.5 GB drive.

Like I said, I'm doing multi-vms so I'm trying to push the drive as hard as I can...

 

well that was my huge surprise today when i looked at the info concerning my stock HD (new 13" MBP)

i thought that Apple did it again but it finally comes from the HD

why the hell would Apple cap the speed to 1.5 Gb ????

to save some battery juice ????


or is it an old HD with SATA instead of SATA II ???
