Plextor PX-256M5S review


We have previously reviewed the Plextor PX-256M2S, a high-performance SATA 6Gbps SSD when it launched, even if its circa-430MBps speed has now been surpassed by more recent SSDs.

The Plextor PX-256M5S is not widely available at time of review, but we have seen it on sale for under £190 in 256GB capacity. Considering its first-division performance, it should make a compelling choice as a high-performance upgrade for any modern...

Issue detecting in MBP


I can speak to the other user who had issues with drives being detected when installed in a MBP. We had the same issue at my College, but it turns out that the flex cables needed to be replaced. It was very odd, but we figured since the drive was...

None to date

Fast, Fast, and Fast


Blazing fast speeds -- POST took me longer than windows boot up even before I activated the RAID controller for my data drive. This drive runs blazingly fast

Great Product


Bought this product because I have other Plextor products and they all are fantastic. This SSD drive is super fast. Cut my Windows start up and shut down time by more than half. Would highly recommend it to anyone who want a fast and super quiet hard...

MBP 15, Early 2011


Installed fresh copy of OS/X Mountain Lion on this drive. The speed difference between the original 500GB 7200RPM Hitachi and this drive is like night and day. So far its working to my expectations. Hopefully it will stay that way
