Specifications, Pricing and Availability
Samsung offers the 840 Pro in four capacity sizes - 64GB, 128GB, 256GB and 512GB. The performance varies between capacity sizes like most MLC SSDs. Today we're focusing on the 840 Pro 128GB and soon the 256GB model review will go live. You may wonder why we're so late with these drives, well
I don't think Samsung really liked our 830 128GB review so we just went out and bought these two drives. In Samsung's defense, they planned on sending us drives, but a FUBAR with the firmware on the media drives meant that the North American allocation needed to go back to South Korea for a flash. Then we started testing with our two purchased retail drives and found new firmware issues, MobileMark 2012 would BSOD every time we ran it. Samsung released a new firmware, version DXM04B0Q and it fixed our notebook power test. We're now ready for the review.
Samsung specs the 840 Pro 128GB with a sequential read speed of 530MB/s, sequential write speed of 390MB/s, random read speed of 97K IOPS and finally random write speed of 90K IOPS. Physically, the 840 Pro uses a 7mm z-height form factor so you can use it in an ultrabook. The mounting points are the same as traditional 9.5mm notebook drives so you can use this drive in a notebook or desktop with a desktop adapter bracket (not included).
Samsung does include a five year warranty as well as a very good software package. The Samsung Magician software rivals that from Intel, these two pretty much tie in the software feature department. Samsung takes it up a notch though with the included data migration software. The software ships on an included CD so you don't have to fumble with an internet download to start using the software.
Newegg lists all four 840 Pro capacity sizes at the time of writing, the 64GB model was sold out though.
