Review: SanDisk Ultra® Plus Solid State Drive (128 GB)

Having already owned the SanDisk Extreme® Solid State Drive and been satisfied with the performance thus far, I decided to go for another SanDisk SSD to upgrade Annabelle’s laptop which is still running on the conventional 5400rpm hdd. This time round, it is the newly launched SanDisk Ultra® Plus SSD. As Annabelle is a light user, a 128GB SSD shall suffice her requirements.

The SanDisk Ultra® SSD is built using SanDisk’s own MLC nand and is based on Marvell’s SS889175 controller. It is compatible with SATA3 (6.0Gb/s) interfaces and is also backwards-compatible with SATA/SATA2 interfaces. Its built is at 7mm thick, and would fit into most ultrabook and laptop. For those who required a 9mm SSD, there is a 2mm spacer included too. The SSD is running at a low power consumption of 0.12w. Hopefully, this will increase Annabelle’s laptop operating hours while on battery. The SSD is backed by 3-year warranty limited warranty.

The performance of the SanDisk Ultra® SSD conducted in-house by SanDisk is stated to be able to achieve the following result:

Performance 64 GB 128 GB 256 GB
Sequential Read (up to) 520 MB/s 530 MB/s 530 MB/s
Sequential Write (up to) 155 MB/s 290 MB/s 445 MB/s
Random Read (up to) 76K IOPS 80K IOPS 82K IOPS
Random Write (up to) 29K IOPS 33K IOPS 39K IOPS

I shall now conduct the test of the SanDisk Ultra® 128GB SSD on my own and also make a comparison with my existing SanDisk Extreme® 240GB SSD.

Indeed, the SanDisk Ultra 128GB SSD is able to achieve the read and write speed as tested by SanDisk. Although this may not be a fair test as I am comparing the 128GB against the previous version of 240GB, we can observe that there is a significant improvement in terms of performance. In conclusion, I am once again satisfied with the SanDisk Ultra range of SSD as a budget upgrade for the existing laptop. The SanDisk Extreme® II SSD should be an even greater improvement when compared to the SanDisk Extreme® SSD.
