I'm a bit concerned about the write speed being below 900... I turned off all sync fils applications and just had Safari / Finder / Diskspeed open.

Ideas?

Look at all you PCIe connected people showing-off :) So, here is a SATA connected 256GB SanDisk.

Hi Everyone,

I just purchased a new Macbook Pro 15" with the 512... for my girlfriend. I was wondering what make is the hard drive and if it is a SLC or MLC?

Thanks.

Goto Utilities>System Information>Hardware>Storage and under Physical Drive read the Media Type.
It will show "APPLE SSD SDxxxxx or SMxxxxx"
SM is Samsung
SD is SanDisk

Thanks. I'll wait for her to open it up tonight.

Best.

I'm not sure about SanDisk but I know that the XP941-based SM0256F/512F/1024F are all made out of MLC NAND.

MLC is actually pretty good enough already. Unless you're constantly doing heavy writes to it, there's no need for an SLC drive.

Meanwhile the Samsung 840 Evo uses TLC.

In terms of reliability, SLC>MLC>TLC.

Only 1TB SSDs can reach 900+ speeds because the 1TB ones use a 4-lane PCIe channel. All other capacities only use a 2-lane PCIe channel.
 
Here is my 1TB PCIe SSD read & write results:

Happy camper here! :D

I think that here is the topic I was looking for, to ask:

- The 512gb ssd of mbp 15' late 2013, is faster than the 256gb version of the same model? Percentage?

- Any estimation of how much speed I will gain, with the mbp 15' late 2013 512gb ssd, over the mbp 15' early 2011 256gb ssd?

I understand the 256 GB and 512 GB SSD sizes are made by Samsung and Sandisk. The Samsung variant is faster. The 1 TB is only by Samsung. There is no way to tell what brand of SSD you are getting on sizes other than 1TB so it is a brand lottery on the 128, 256 and 512 GB variants.

Download blackmagic disk speed test app for free

Here are my two machines:

Late 2013 13.3 rMBP (512G, 2.8, 16G)
Late 2012 13.3 rMBP (128G, 2.6, 8G)



OK, I'll play.

Late 2013 13" rMBP 2.4 | 8GB | 256GB
Samsung SSD
FileVault ON
Repaired permissions and restarted. No other program running
BlackMagic test done with 1GB file setting.


I may be doing this wrong. Someone please help/ explain: click Start to commence the test and then click it a second time to Stop it.
How do you guys time it? How long did you let the test run?
I stopped it trying to get speeds amongst the ones I was seeing.

Samsung is the sole supplier of the 512GB and 1TB variants. The brand lottery' limited to 128 and 256GB variants :D
