Over the past year ADATA has released a number of different solid state drives aimed at different market segments. Not that long ago we took a look at ADATA’s XPG SX930 which was aimed at gamers and enthusiasts. Today we will be taking a look at the Premier SP550 which sits as ADATA’s entry-level solid state drive aimed at people who are looking to upgrade to an SSD and still want very good performance. The drive features the Silicon Motion SM2256 controller matched with SK Hynix TLC NAND. This is the first time we’ve seen this combination together. The 240GB version of the drive that we are reviewing today boasts sequential read and write speeds of 560 MB/s and 510 MB/s respectively. Let’s get this drive on our test bench and see what it can do!
Samsung is a very large player in the solid state drive market, but you may not have known. This is because they sell their drives in bulk to companies like Apple to use in their products. That is why they are not an known in the consumer or enthusiast market. In fact Samsung is the largest producer of flash memory in the world. One thing that is great about Samsung solid state drives is that everything inside is made by Samsung, the NAND, controller and DRAM cache. This makes it very easy for Samsung to correct issues or fix problems because everything is done in-house. We saw this on Samsung’s 830 Series solid state drive and the big difference between the 830 and 840 is that the 840 Series uses TLC NAND chips instead of MLC. We will get to the difference in just a bit. The controller on the 840 Series has also been updated. The 120GB version we are testing today has read and write speeds of 530MB/s and 130MB/s respectively so it sort of fits into the entry-level segment. Let’s take a look…
Last week we showed you Plextor’s TLC NAND-based 2.5-inch drive they were showing off at CeBIT. Plextor also had a next generation from factor (NGFF) TLC NAND-based drive on display. We have seen a lot of NGFF drives at CES. They are small 42 x 22mm modules with a PCI-Express 2.0 interface. They are designed for use in next generation Ultrabooks. Plextor will be selling these drives in 128GB and 256GB capacities.
Plextor is showing an unnamed line of consumer solid state drives that feature 19nm triple layer cell (TLC) NAND flash memory at CeBIT. They were showing three different capacity drives, 128GB, 256GB and 512GB. The drives feature 256MB, 512MB and 768MB of DRAM cache respectively. All three drives are in a 2.5-inch form factor and have a SATA 6GB/s interface. They are powered by the Marvell 88SS9189 processor.
