rMBP 13" 2015 SSD Problem

[josesilva]

Hello everyone,

So I've just bought this macbook pro 13" with retina display early 2015 and I seem to have some problems with my SSD. After watching some disk speed tests from other users I saw that mine arent the same.

I only get about 300 mb/s on the write side when other's get about 600 mb/s.

Is this normal ?

Am I testing wrong ?

And your SSD size is....

 

[josesilva]

128, sorry

 

[ZBoater]

Yeah, I figured. Those high speeds are for the larger SSDs.

 

[josesilva]

This guy is reviewing the exact same model and he has greater speeds.

Mine gets 600+ Write and 1200+ Read speeds on a 128GB SSD

I get around 1400/1400 with my 512gb 2015 rMBP

 

[ZBoater]

Yeah, but op is getting 300/600, which is about half.

Is the drive mostly filled up? Which manufacturer? Check in System Information app>SATA on side column bar

 

[josesilva]

Same numbers more or less for my new rMBP... About 640+ Write and 1300+ Read on a 5gB stress test for a 128gB SSD.

Do ou have Filevault encryption turned on? That will slow it down some.
