SSD Speed test

[police340]

Does anyone know how to run the speed test on an internally mounted SSD drive in 27" iMac? When I try to run the test, it tells me drive is write protected. I was able to run the test prior to mounting it inside the iMac. Thanks.

You can use the following applications to benchmark the speed of your HDD / SSD:

• AJA System Test
• Blackmagic Disk Speed Test
• Xbench

uhm... is this a normal speed for SSD (standard Apple SSD)?

writing 178mb/s, reading 205mb/s on average.

get a vertex 3 max iops
550 read
502 write

no loss of speed since i installed the drive almost a year ago

Back to my original question. The speed tests do not seem to work on the internal SSD. I tried BlackMagic and one of the one from AJA. They do not work. Where BlackMagic tells me the drive is write protected, the AJA just doesn't do anything, the start button just flashes after clicking on it once. The internal ssd is the boot drive so it is not write protected. Thanks

AJA System Test sometimes has that bug. BlackMagic works most of the times on my internal SSDs though. What about XBench?

And what Mac OS X version do you actually run?

Mac OS 10.7.4, Xbench actually worked. Here are the results. This is 480Gb OWC 3G drive. What do you think of these results? I am rather new at these speed tests. Thanks, Bill

I just got a samsung ssd evo 850 t1b for my macbook pro 2009 17" it reads only like this. should i consider buying a 256sSd and save the money instead?

I use Black Magic version 3 released a month or two ago and if you are not looking at around the 600 read and 450 write there is something wrong.

dss your speeds are okay but a 3Gb/ps SSD is throttling the iMacs 6Gb/ps capacity.

the verison of black magic is 3 too. What am i doing wrong? i didnt clone my el capitan, i did a recovery mode way. What are your settings for black magic?
[doublepost=1507783298][/doublepost]yeah its not looking like its going to 600 read and 450 write...idk what i did wrong
[doublepost=1507783454][/doublepost]ok so what does this mean? is that bad?

Your 2009 MBP can only achieve SATA 2 speeds, i.e. the motherboard on your machine is the bottleneck. The values are fine (for this setup).

Nothing SATA 2 speeds on your older machine is limiting your sequential read write speeds. Don’t worry too much about this as in most day to day activity this is not the speed metric you care about anyway, random i/o is much more important to you.

Use any size modern ssd you like with this limitation it will make little difference to you.

More importantly does your machine feel faster in every operation? If yes then the upgrade is worth it, that simple really, an 8 year old lapto is no longer ever going to be a speed demon if you want that you need to buy something new.

Sata 2 speeds is all your model of laptop can achieve. That means you will never reach the speeds of Sata 3, no matter what SSD you use. If you want higher speeds you will need to get a laptop model which supports sata 3.
