worth to spend on top-tier SSD for using in a laptop with SATA 2 interface ?

I am planning to buy a Samsung 870Z5G-X03 laptop for photo and video editing purposes and will replace the original HHD with SSD. My eyes are on the Samsung 840 evo/pro and 850 evo/pro which seems to be getting favorable reviews.

According to Samsung, the laptop has got a SATA 2 harddisk interface , not SATA 3. I believe this will limit the performance I can get out of the SSD so I am wondering whether there will still be perceivable performance different between the four models of SSD mentioned above .

Any advice will be appreciated.

 

Performance will be capped to about 260MB/s. Personally I believe any reliable SSD will be good enough and you will definitely feel the upgrade from HDD to SSD. Make sure you buy an SSD which will give you enough space and look for a good price.

 

I would check with other owners of this family of notebooks whether the HDD interface is only SATA 2. I don't recall anyone who has done the SSD upgrade reporting any problem with the interface speed.

I think that SATA2 spec is for the installed HDD. The interface is SATA3 (unless they're shipping 2006 tech in 2015...).

 

I would say tiller's assertion is probably 100% correctly.. Highly unlikely it's SATA II limited as that was stopped in 2010-2011..

 

Just want to answer the OP's question with regards to SSD choices.

Forget the TLC drives - they're a nightmare waiting to happen. The 850 Pro and the SanDisk Extreme Pro ~1TB models are the only ones to consider for your workflow. And don't forget that the capacity of the SSD has to be considered after you have OP'd it by at least 25% (as per Anandtech) or 30%, by me .

That leaves about 650GB of usable capacity, but will give you higher sustained performance, lower WA factor and a more reliable platform on which to work from every day for the lifecycle of your new platform.

See:
Samsung 840 EVO read speed drops on old-written data in the drive - Page 156


The slow read performance (of files older than ~30 days old) is not limited to just the 840 EVO, it is also present in the original 'plain' TLC Samsung 840 drive too.

Do yourself a favor and disregard TLC from any vendor as they are all suspect at this point in time - the 840 'plain' version took almost a year to show that it too slows down to below HDD levels.


Good luck.

 

The notebook have HM86 which have both SATA2 and SATA3 support.
Looking at the review, it seems that the drive is connected to SATA2 though. If its the only port available he is stuck with SATA2

If Samsung so dumbed down the platform by using a SATA2 Interface on the main drive - don't buy this for your intended workflow.

But I still think even they are not that stupid... crosseseyes

 

Guys Guys.. The HDD is a SATA II HDD.. I googled it and hence this is why the speeds are SATA II.. It's highyl unlike that it's been dumbed down..

 

Yeah; already stated that in my first post on this thread. But, we are talking about Samsung here...

 

No, the interface the drive is connected to is 3Gb/s ie SATA2. HM86 contains both SATA2 and SATA3 and its up to OEMs.
I agree that using SATA2 is stupid if SATA3 is available, but you never know with OEMs.

 

Cloud, the HDD is a SATA II HDD and not SATA III.. Google the specs up.. So even if the interface it's connected to is SATA III, it will run at SATA II speeds...

 

Yeah, I also read it as stating the drive's logical connection speed, not the physical interface's.
