Plextor M5 Pro (256GB) Review
by Kristian Vättö on August 31, 2012 11:32 AM ESTPerformance vs. Transfer Size
All of our IOmeter sequential tests happen at a queue depth of 1, which is indicative of a light desktop workload. It isn't too far fetched to see much higher queue depths on the desktop. The performance of these SSDs also greatly varies based on the size of the transfer. For this next test we turn to ATTO and run a sequential write over a 2GB span of LBAs at a queue depth of 4 and varying the size of the transfers.

Sequential read performance is marginally faster compared to M3 Pro and overall excellent at all transfer sizes.
Sequential write speed is also slightly better than what the M3 Pro offers, although performance between IO sizes of 4KB and 64KB could be a bit better.

Our it shop has installed about 50 Agility 3s. 2 were DOA and the rest have been fine. Agree with you on the PITA firmware update process.stalker27 - Tuesday, September 4, 2012 - link
I was wondering if Plex kept their reputation, where I'm from they kinds faded away from the market.ksherman - Friday, August 31, 2012 - link
With the M5S only seeming to be marginally slower than the Pro series, but a good bit cheaper, what would I be missing if I opted for an M5S drive?DukeN - Friday, August 31, 2012 - link

I don't know about you guys but I don't have anything in my computer that's older than 3 years.Beenthere - Friday, August 31, 2012 - link
The Pro version should be the only version Plextor releases IMO and they should be priced as the base model -which they are. The non-Pro versions are basically models without proper firmware to facilitate best performance. The base models are just under-achievers used to justify higher prices for the Pro models. Not cool IMO.BTW the minute theoretical gains do not make any substantial gains in typical operation so just buy whatever is on sale if you're ready to jump in a be an unpaid SSD beta tester as this is still very "immature tech" as Anand has stated.

SSDs are not immature tech. Two years ago they were. I personally have not bought a mechanical hard drive in 2+ years and I don't ever intend to do so again.sheh - Friday, August 31, 2012 - link
You should beware of longer term data retention.
