A week or so ago, we published a review of the MyDigital BP4 that was ‘ a wolf in sheeps clothing’ in a way as it was a 120GB SSD with an exterior label claiming to be 240GB.
After posting the review, MyDigitalSSD called and insisted on sending the REAL 240GB BP4, claiming that it’s performance would be something to write about. Given our workload, one review of a specific model would normally be enough UNLESS we observe a difference worth letting you know about.
Higher capacity, same model, and a second report… Does that say anything to you?
MYDIGITALSSD BP4 240GB 6GBPS SSD
The MyDigitalSSD Bp4 is available in capacities of 60, 120, 240 and 480GB and is called the ‘Slim 7 Series’ as it is a 2.5″ notebook drive that is only 7mm in height, making it suitable for todays new ultrabook designs. Performance of the BP4 is listed on the site at 560MB/s read and 530MB/s write with up to 80,000 IOPS at 4k aligned write disk access. The is a SATA 3 (6Gbps) SSD that is fully backwards compatible to SATA 2, has a three year warranty and is one of the lowest price SSD releases we have come across yet. We can find its price right now for $159.99 for the 240GB we are reviewing today, placing it at 0.66/GB. The 120GB version also has an excellent price at $89.99 with the 60GB following behind that at $59.99.
The exterior casing of the BP4 is of a flat black aluminum two piece construction and there are four screws on the bottom that hold the shell together. Inside, we have a printed circuit board(PCB) which contains a Phison PS3108-S8 four channel controller that operates at a maximum frequency of 300MHz with 40MHz external crystal. In plain English, the consumer should realize longer battery life on a portable system through this design.
Also found on either side of the PCB are eight modules of Toshiba 19nm Toggle Mode NAND flash memory with a product number of TH58TEG7DCJTA20, as well as a Powerchip Semiconductor 256MB DRAM cache right beside the Phison controller.
Of particular interest is Toshiba’s new Toggle Mode 2 NAND flash memory which really boosts sequential read performance significantly. More important than the overall performance, however, this memory reaches faster speeds at smaller file disk access which could result in a visible performance boost as we will demonstrate in our ATTO testing.
Very nice assessment!
So, would you recommend to replace the current 5400rpm HD in my laptop by the MyDigitalSSD BP4 Slim 7 Series SSD and expect an improvement in overall laptop performance? Currently the WEI (windows experience index) is 5.9 because of the HDD data transfer rate, which is determined by the lowest subscore. The next lowest subscore is 6.5 determined by the graphics card. Thanks for your opinion
Even better than numbers, your system will realize a significantly quicker start time and visible performance upgrade…and it is a great price!
