Plextor M3 Pro (256GB) Review
by Kristian Vättö on July 1, 2012 1:45 PM ESTAnandTech Storage Bench 2011, Light Workload
Our new light workload actually has more write operations than read operations. The split is as follows: 372,630 reads and 459,709 writes. The relatively close read/write ratio does better mimic a typical light workload (although even lighter workloads would be far more read centric). The I/O breakdown is similar to the heavy workload at small IOs, however you'll notice that there are far fewer large IO transfers:
| AnandTech Storage Bench 2011—Light Workload IO Breakdown | ||||
| IO Size | % of Total | |||
| 4KB | 27% | |||
| 16KB | 8% | |||
| 32KB | 6% | |||
| 64KB | 5% | |||
Switching to Light suite doesn't change the story; the M3 Pro is still a brilliant performer. Only the Kingston HyperX 3K is faster, but once again the 0.6MB/s difference is insignificant.

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.

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
