Would this be ok? Or would it be better to find a drive that is 3GB/s?

To Dan and Mayer, so if the drive says

"Interface: SATA 6Gb/s (SATA 3GB/s compatible)"

Would this be ok? Or would it be better to find a drive that is simply 3GB/s?

This is the drive I was looking at:

Does anyone have any reviews about Crucial? Are they to be trusted? Is that price reasonable? I need to replace my battery in my laptop and thought, while I'm at it, may as well soup up my laptop by getting a fantastic HDD and bigger RAM. If you have any suggestions, I would be most grateful.

How about using a hybrid drive? Seagate offers a nice one Seagate 1TB SSHD for a lot less.


Sorry Machead, wrote my comment and then made an account. New and there was no option for add comment until after I made the account.

So it won't be detrimental at all that it's running at a lower speed? Won't cause any issues?

Dan, I have seen A LOT of negative posts about Seagate drives and a couple of friends have had bad experiences with Seagate too. Don't really trust them. Plus, I don't mind paying more if it means I will reap more benefits.

Has anyone used Crucial before?


Also, thanks for the help. =)


Crucial is a top tier memory company - I would not suspect their SSD and HD to be substandard quality.


Thank you very much for your advice machead3. =)

Vaneet -

While Seagate has had its share of bad HD's so has the other big manufactures. I would focus on the warranty side and think how long I will be using this system with this drive. Storage solutions are still improving (I/O and technology). So your storage investment will likely not be transferable to your next system.

We've had good success with the Seagate SSHD drives (better than 100 in use). We at one point took the optical drives out of the laptops and put in SSD's but we found it wasn't in the long run any better than using the hybrid drives.

Don't get me wrong here I do like SSD's, I use them in our desktops as much as possible as the boot drive with the other drive being a standard HD.

The bottom line here is any drive HD or SSD that can work correctly in your system is fine.

The only issue is making sure your systems firmware is up to date (check out this Apple TN: EFI & SMC firmware updates for Intel-based Macs). And make sure your drive is able to work at the SATA II spec (3.0 Gb/s) your system has.

Hi Dan,

Thank you very much for your help. I'm planning to keep this is laptop around for a long time. It's still fully functional and have no issues with it. It's just been nearly 4 years now, so it's slowing down a little. I thought, while I have some money, I may as well put it towards giving my laptop an added boost. I know other companies do have problems too, but Seagate has a lot of negative reviews and family members have had issues with their drives too, so very wary about trusting them again.

The warranty on the Crucial drive I mentioned has a 3 year warranty, which is always good. It states that it is a 6GB/s drive, but is 3GB/s compatible. It states it as an available upgrade for my device also. I was just wondering whether this is common and whether the drive would work fine working at 3GB/s rather then 6. Or whether running at a slower speed could cause an issue. I was thinking not, but was hoping to double check.

And yes, don't worry, my firmware is all up to date. Thanks for your help. =)


Think of it this way the systems SATA I/O speed (i.e. SATA II 3.0 Gb/s) is the speed of the road and the I/O speed of what ever drive you put in needs to be able to roll at the SAME speed. IF you have a drive which can go two different speeds (i.e. SATA II 3.0 Gb/s & SATA III 6.0 Gb/s) it will only go as fast as the roads speed in this case SATA II 3.0 Gb/s.


Haha great analogy! Thanks for your help. I didn't think there would be an issue. It is only because I was reading up about RAM, which people say is backwards compatible (so RAM can run at slower speeds if necessary), but there were a few comments that said that it could cause an issue. No idea if this is true or not, but thought what if it is true and such issues could be the same for HD/SSDs. Just figured it would be best to double check with some trustworthy people in the know. =)

Thanks for everyone's help.
