Storage/SSD by stefan @ 2011-11-08
The Crucial 256GB m4 SSD comes now with an improved firmware and we now get read speeds up to 500MB/s sequential. Compared to the SandForce offerings, the m4 comes with a good price/performance ratio, so we could afford getting higher capacity SSDs. The tested model also comes with a Data Transfer Kit composed of hardware (USB to SATA adapter) and software (EZ GIG IV Cloning Software).
The software CD contains:
-EZ Gig IV Cloning application
-Manuals
-Datasheets
-Acrobat Reader Software
-Technical Support information
Mac users are not forgotten, so the ShirtPocket SuperDuper! Application is also included:
For extra protection, the SSD is wrapped inside an anti-static bag, fully sealed:
The SSD chassis is covered in a gunmetal paint and on one of its sides we can find a sticker with the brand name:
On this side we can also locate the SATA Data and Power contacts:
The other side comes with another sticker which tells us the total capacity of the product, supported SATA standard (6Gb/s), firmware revision (0009), the serial numbers and power rating:
One of the screws from this side is covered with the warranty sticker:
The SSD PCB is covered with a total of 16 Micron 25nm NAND Flash (8 on each side), along with the Marvel controller:
The Marvell SSD Controller chip is type 88SS9174-BLD2:
As mentioned before, the opposite side contains the rest of 8 NAND Flash, along with the buffer RAM (unlike the SandForce SSDs that do not need extra RAM placed on the PCB):
The code name, D9LGQ, of the buffer RAM tells us that it is DDR3, clocked at 1333MHz, with a total capacity of 128MB:
