Crucial MX100 512GB Two-Drive SSD RAID Report

By: Jon Coulter | RAID in Storage | Posted: Sep 3, 2014 1:13 pm





Crucial's MX100 SATA III SSD is available in three capacity sizes, 128GB, 256GB, and 512GB. Specifications list the 512GB MX100 SSD as capable of 550MB/s sequential reads and 500MB/s sequential writes. Random read/write speed is listed at 90,000/85,000 IOPS. Crucial's MX100 comes in a 2.5" x 7mm z-height form factor, and ships with a spacer should you need to increase the drive's thickness to 9.5mm.


The MX100 supports AES 256-bit hardware encryption, which meets TCG Opal 2.0 and IEEE-1667 standards. Microsoft's eDrive is also supported. Crucial backs the MX100 with an industry standard three-year warranty, with a 72 TBW limit.


Because this is a RAID review, we are going to focus on performance rather than features. For a more in-depth look at the Toshiba Q Series Pro feature set, I will refer you to Chris Ramseyer's extensive review of Crucial's MX100 512GB SSD.



Drive Details - Crucial MX100 512GB SSD




Crucial packages their MX100 in an attractive blue and silver flip-top box. The drive is pictured on the top of the box.




The rear of the box lists the contents, although there is no mention of the included Acronis migration software.




The MX100 512GB ships with a download key for Acronis migration software, and a 7mm to 9.5mm black plastic spacer.




The top of the drive's enclosure is formed from a single sheet of aluminum. A manufacturer's sticker lists the drive's capacity, shipping firmware, model number, serial number, and various bits of other relevant information.




The bottom and sides of the drive's enclosure are formed from a single piece of cast aluminum. There is an attractive blue sticker centered on the bottom face of the drive's enclosure.




Here's what Crucial's MX100 512GB SSD looks like completely disassembled. There is a conductive thermal pad to wick heat from the drive's controller and DRAM package into the thick cast aluminum half of the drive's enclosure.




On this side of the PCB there are eight Micron branded 16nm BGA NAND packages, one DRAM package, a row of small capacitors providing host power-loss protection, and Marvell's newest 88SS9189 flash Processor.




There are an additional eight NAND packages on the opposite side of the PCB.



Test System Setup




- Drive Properties




The majority of our testing is performed with our test drive/array as our boot volume. Our boot volume is 75% full for all OS Disk "C" drive testing to mimic a typical consumer OS volume implementation. We are using 64k stripes for our two to three drive arrays, and 32k stripes for our four to six drive arrays. C-states and speed stepping are both disabled in our systems BIOS, the high performance power plan is enabled in Windows, write caching is enabled in RST control panel, and Windows buffer flushing is disabled.


All of our testing includes charting the performance of a single drive, as well as RAID 0 arrays of our test subjects. We are utilizing Windows 8.1 64-bit for all of our testing.
