Very Slow SSD 530 240Gb on Mac Mini 2010

New Contributor

Why is this device so slow ?

I am extremely disappointed with this SSD.

Apart from the issue with the unable to reboot (device not detected on reboot)

it's very slow, I can't believe it, something is wrong !

I was hoping for a performance boost, this is ridiculous.

You may want to check with the system manufacturer for a list of validated SSDs in regards of compatibility, this is highly recommended for Apple* devices.

With my Macbook pro Mid 2010, and Intel 530 240gb with DC12 firmware

I have the same problem - I also think this ssd is slow - I am only getting about 200 mbps write and 260 mbps read speed. Very disappointed, as I the reviews online pointed to speeds in the range of 500 mbps.

I tried the installation two ways - one by cloning the system partition using carbon copy cloner, and another using a fresh install from super-drive and updating .. In both cases, speed didn't change.

If it matters, I have 4 partitions on the drive. The system partition is of size 100gb, with about 40gb free space after migrating my content.

In response to both KIRESP & PKR,

THE SSD IS NOT THE PROBLEM. It's the fact that both of you are using MID-2010 MACS which are only capable of SATA (3GB/s). Which is why you are only seeing max 200MB/s give or take. You will only achieve 500 MB/s on a SATA (6GB/s) interface.


The problem is not the Intel 530 SSD drive, the problem is your old 2010 Mac. Regardless of which SSD (SAMSUNG, CRUCIAL, INTEL) you went with, you will only be able to see 230 MB/s R/W because of your old ass SATA interface.

You can just get a high-speed card, some of them are quite inexpensive, for much higher speeds on a 2011 or earlier Mac Pro. I say this for anyone else who may have arrived here from Google.

The last poster was rude and for no good reason, because shows your machine as having a 6 GB/s interface. The Intel guy may have been right. You might want to try a TRIM enabler. MacBook Air "Core 2 Duo" 2.13 13" (Late '10) Specs (Late 2010, BTO/CTO, MacBookAir3,2, A1369, 2392) @

That's for a LATE 2010 model, I assume you are referring to the what-passes-for-a-name-at-Apple and not just the year it was made.
