Looking into M4's, anyone know what the difference between these two ? :s
CT128M4SSD2 & CT128M4SSD1 both made by Crucial and both the same price it seems.
CT128M4SSD1 is 7mm height
CT128M4SSD2 is 9.5mm height

I think you missed her sarcasm.
CT128M4SSD1 is 7mm height
CT128M4SSD2 is 9.5mm height
Thanks for that , can I use any of those two in my mbp? I seem to remember reading 7mm only?
I'm hoping some of you can help shed some light on my situation.
I have a current 13" 2.8 i7 MBP (upgraded to 16GB of RAM) that I recently installed a 256GB Crucial M4 SSD into. I cloned my previous 40GB SSD (that has Snow Leopard 10.6.8 on it) via Time Machine and the drive is SLOOOOWWW. Startup takes minutes and I'll get beach balls nearly every 5-15 minutes (mostly random, even while browsing the web (non flash or graphic intensive sites) and more frequently when using more CPU intensive programs such as Photoshop.
I've repaired permissions, zapped PRAM, and can't figure out the issue. I've been running this setup for the last week, hoping it would work itself out, but unfortunately that hasn't been the case.
I've ran the OWC 40GB SSD in the MBP (the physical drive instead of the Crucial) and it's fast and speedy, just like I'd expect this Crucial M4 SSD to run...I can't figure out the problem.
Hopefully you can help out and I look forward to any advice you can lend.
Thanks in advance!![]()
Installed the Sandisk Extreme last night and it works fine. Very speedy performance, negotiates @ link 6gb speed and trim working. Not a single issue so far and that was after cloning my drive.
I have a unibody MacBook 5,1 with the NVidia MCP79 AHCI chip set(early 2009) and I am really confused about what SSD I should or even can get. I currently have the 160GB 5400rpm drive that the computer was shipped with and the system lists as 3 Gigabite link speed and 1.5 Gigabite Negotiated Link Speed. I have heard people having issues with the new SATA III drives in the 5,1 NVidia set up. Does that eliminate the Intel 330, Samsung 830, and the Crucial M4? If so, what is the best SATA II drive on the market for the price?
I really would love to take advantage of the rebate Intel currently has on their 330 series drives but don't want to buy something that causes more headaches than it is work.
Thanks,
Brian
I've installed the Sandisk 240 Gb extreme with no issues.
However, performance is far from expected - on par with my previous m4 128 Gb

Certainly nowhere near this mactrast review http://www.mactrast.com/2012/03/review-sandisk-extreme-ssd/

Any ideas why? Link speed is 6 Gbit, I reseted PRAM and SMC, speed is the same with or without TRIM activated.
Thanks.
The new BlackMagic uses incompressible data whereas previously it used compressible from what I have read. That would explain the discrepancy between your test and that of Mactrast. I'm not convinced of the BlackMagic test to be honest. There are plenty of reviews showing the Sandisk performing very well, many even higher than that review you have linked to. I would try some different benchmarks or even make some up yourself to satisfy. Also, what settings did you use for your Blackmagic test?
As I figured. Two different benchmarks and two entirely different sets of results. I'll test mine again in a bit and feed back.
