Plextor M3 Pro (256GB) Review
by Kristian Vättö on July 1, 2012 1:45 PM ESTThe Plextor M3 Pro
The packaging for the Plextor M3 Pro is similar to the M3, with the main difference being the glossy design instead of matte. Inside the box you'll find a 3.5" bracket, mounting screws, and a software disc with cloning, backup and performance analyzer utilities—along with the SSD of course. Unfortunately there is still no toolbox utility included, at least not in our review unit, but I have some good news. Plextor has released a tool called Plextool and it's available free of charge for all owners of Plextor SSDs. We'll have more information about Plextool on the next page.
The exterior design follows the same guidelines as the M3, but Plextor has opted for a light grey metal for M3 Pro whereas the M3 uses a much darker, nearly black metal. On the back side sticker you will find info regarding capacity, serial number, and (shipped) firmware of the drive.
Another big difference between the M3 and M3 Pro is the fact that M3 Pro has height of 7mm while the M3 measures in at more common 9.5mm. The thinner design makes the M3 Pro more suitable for ultrabooks for instance.
Opening the cover reveals a familiar interior—we have seen this with Plextor M3 and Corsair Performance Series Pro already. Only the thermal pads are thinner in order to make the M3 Pro 7mm thick.
The NAND is once again from Toshiba and there are a total of eight NAND packages on the PCB. These are 32GiB quad-die packages and are manufactured using Toshiba's 24nm process. As in all consumer grade SSDs, the NAND is 2-bit-per-cell MLC NAND. There are also two 256MiB DDR3-1333 chips from Nanya, which gives the drive a cache of 512MiB.
The controller doesn't surprise either as it's Marvell 88SS9174-BLD, which is what we found inside the M3 as well.

Three things I forgot to include in my post above:- The Plextor needs to be reformatted for the Mac. You use Apple's Disk Utility to handle that, as with any other drive.
- Cloning the original drive using DU's Restore function will also automatically clone Lion's hidden Recovery partition.
- Absolute SSD performance is limited by my 2010 MBP's 3 Gb/s SATA interface, so I could have bought a cheaper last generation drive. However I hope to be keeping this pricey SSD long enough for it to see at least one more host computer, and that will support faster transfers.

Pretty much ALL new SSDs are SATA3.0 / 6GB/s... so its not really an issue.Its older tech or mix tech models that are SATA2.

Not with the regular updater at least. In theory, someone could modify the installer and make it possible though.Kyanzes - Monday, July 2, 2012 - link
"relatively unknown brand" :)Okay.

Yes they are relatively unknown. Yes they used to be more well-known but only for optical drives.eanazag - Monday, July 2, 2012 - link
I would like to see a 2.5" HDD at 5400 rpm and 7200 rpm sample data for a baseline included in the reviews. I don't care if they ever get updated after that. I would just like to be able to quickly see where the mechanical drives chime in.Performance would data would be icing, but power data is nice.
If I upgrade my users to a drive off this list, which is very likely. I'd like to be able to tell them if they are going to take a hit on battery life or a boost.

They stopped doing that some time ago because it messes up the charts somewhat. Basically, they just don't compare... and that was before the SATA 6Gbps drives came out.Here is a early 2011 review with a WD VelociRaptor (The fastest HD money can buy for a consumer drive). And yet, its a sliver. Only SSDs that perform almost as slow are the bottom end SSD. And keep in mind, the Raptors are 2-3 times faster than a 5400RPM drive.
http://www.anandtech.com/show/4346/ocz-agility-3-2...
RANDOM READ (MB/s)
00.68 = Raptor
58.10 = Intel X25-M G2 (still a very good drive)
93.50 = Crucial C300 (early 6Gbps drives)
Sequential READ (MB/s)
145.30 = Raptor
226.30 = Intel X25-M G2 (still a very good drive)
307.20 = Crucial C300 (early 6Gbps drives)
392.20 = Intel 510 SSD (6Gbps)
A modern high end SSD is about 100x faster in random R / W operations over any HD.
Oh, here is a GOOD older 2010 review which includes a Seagate 5400 RPM 2.5" drive. OUCH!

See how the chart becomes somewhat meaningless? And thats with 3Gbps drives!
Imagine looking at a chart comparing a 16mhz 286 to a quad core 3400mhz i5 CPU.

Probably, assuming there isn't some checksum that can't be cracked to flash the drive.In my experience, almost all drive firmwares can be flashed.

Speed and performance of such a device is important, but not as important as reliability. Reliability is hands down my top priority. Just wanted to mention this.octoploid - Tuesday, July 3, 2012 - link
There is already an unofficial tool available that can transform a normal M3 into an M3-Pro:http://bbs.pceva.com.cn/thread-47279-1-1.html
