Plextor PX-128M1S 128GB Solid State Drive
18 April 2010
Conclusion: Garbage Collection: While SSD's offer many benefits, there are some downsides to using flash memory. One of the biggest issues people run into is performance degradation. Over time, an SSD will run out of fresh blocks and will have to write over data the file system has marked as deleted.
Pros: 128GB capacity, Well constructed aluminum casing, 64MB on-board cache, Low power consumption, Supports S.M.A.R.T., NCQ and wear leveling, Includes Acronis True Image, 3 year warranty
Cons: Does not support TRIM, Garbage collection does not work as well as advertised, Pricey
Summary: HD Tune Pro is a relatively new benchmark for us here at BCCHardware as we don't typically do a lot of storage reviews. This benchmark now allows random read and write tests to be performed, and the results are displayed on a very handy chart.
Pros: Well designed/finished drive, 64MB cache keeps response time low., Drive performs consistently if NAND is "clean" or "dirty", Exceeds rated read performance, Acronis True Image is handy for system migration
Cons: Priced same as a high-performance drive, 3 year warranty seems weak compared to other 5 year & 10 year warranties, Doesn't reach rated write speed in any tests
