Aerocan Posted October 13, 2011 Share Posted October 13, 2011 I just purchased a Mac Mini Server yesterday and replaced one of the HD with a Corsair Force 3 SSD. I have run some speed test and the results are not so good. Here are the Mac Mini Specs. Model Name: Mac mini Model Identifier: Macmini5,3 Processor Name: Intel Core i7 Processor Speed: 2 GHz Number of Processors: 1 Total Number of Cores: 4 L2 Cache (per Core): 256 KB L3 Cache: 6 MB Memory: 8 GB ---------------------------------------------------------- Vendor: Intel Product: 6 Series Chipset Link Speed: 6 Gigabit Negotiated Link Speed: 6 Gigabit Description: AHCI Version 1.30 Supported Corsair Force 3 SSD: Capacity: 120.03 GB (120,034,123,776 bytes) Model: Corsair Force 3 SSD Revision: 1.200000 Serial Number: 11296501000006800000 Native Command Queuing: Yes Queue Depth: 32 Removable Media: No Detachable Drive: No BSD Name: disk0 Medium Type: Solid State TRIM Support: No Bay Name: Lower Partition Map Type: GPT (GUID Partition Table) S.M.A.R.T. status: Verified ---------------------------------------------------------------------------- Here are the speed test result (202 MB/s and 139 MB/s) (See Attachment). This is not even half of the advertised speed. Is there anything I can do to correct the situation. Link to comment Share on other sites More sharing options...
Isaac7 Posted October 14, 2011 Share Posted October 14, 2011 Those are terrible benchmarks, however download ATTO and use that to benchmark your disk. You might need to install windows via parallels or bootcamp. Also make sure that you didn't clone your HDD, but did a fresh install. According to this: Product: 6 Series Chipset Link Speed: 6 Gigabit Negotiated Link Speed: 6 Gigabit Description: AHCI Version 1.30 Supported Everything looks fine.

Aerocan Posted October 15, 2011 Author Share Posted October 15, 2011 Why does it make a difference if I run it as a Windows machine? Does the product (SSD) have an incompatibility with OSX 10.7? Does Window do a better job at handling SSDs? Why not just accept the result i'm getting with the Mac. Any ways this is the computer on which I want to use a SSD and I need it as a Mac version. I own many Mac Mini servers and have no Windows license. If this product is incompatible with Mac computers, should not it be stated clearly on the Corsair's specs and publicity...

Wired Posted October 17, 2011 Share Posted October 17, 2011 He wasn't saying that it would run better on Windows. ATTO is what the rated specs are from and ATTO is a Windows program. He was offering suggestions on how you can test it so as to directly compare with Corsair's testing methodology. Link to comment Share on other sites More sharing options...
Aerocan Posted October 20, 2011 Author Share Posted October 20, 2011 I just found out that apparently the Black Magic Speed test software for Mac has recently changes it's way to perform speed tests. I have found other tools that give a very different result. It works for Mac and Windows. I would be curious to see how others compare to what i get.
