Kingston SSDNow UV400 480GB Solid State Drive Review

We have seen almost all solid state drive manufactures release an "entry-level" drive. This is mainly because of the ready availability of TLC NAND. While these entry-level SSDs do not have the performance and endurance of the high-performance SSDs we all love, they most definitely offer better performance and endurance than traditional hard drives. Kingston is one such company that has recently released an entry-level solid state drive and today we get to take a look at it. The drive is the SSDNow UV400 and it is powered by the Marvell 88SS1074 SSD four-channel controller with Toshiba 15nm 2D planar Triple-Level Cell (TLC) NAND. The drive offers sequential read and write speeds of 550 MB/s and 500 MB/s respectively along with a random 4K IOPS read and write of 90,000 IOPS and 35,000 IOPS respectively. Let's jump in and see what the SSDNow UV400 from Kingston is all about!

Crucial MX300 750GB Solid State Drive Review

3D NAND is something we started talking about two years ago when Samsung released their 850 Pro solid state drive which was the first consumer solid state drive to feature 3D NAND. With the launch of the MX300 Series Crucial becomes the second company to use 3D NAND in a consumer solid state drive. The drive is engineered with Micron 3D NAND technology, resulting in an endurance rating of up to 220TB total bytes written by leveraging larger NAND cells to deliver top-notch performance and prolong endurance. Furthermore, Dynamic Write Acceleration, a technology that uses an adaptable pool of high-speed and single-level cell flash memory, enables faster saves and file transfers. Compared to 16nm planar NAND, Micron’s 3D TLC NAND triples that density. This not only will help lower solid state drive pricing, but also enable higher capacity drives. Currently the MX300 is only available in a 750GB capacity, which has a price of only $199.99.

ADATA Premier SP550 240GB Solid State Drive Review

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 840 Series 120GB Solid State Drive Review

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 <a href="https://www.thinkcomputers.org/samsung-830-series-128gb-solid-state-drive-review/">Samsung’s 830 Series</a> 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...

Plextor’s NGFF TLC NAND-Based Solid State Drive

<a href="https://www.thinkcomputers.org/plextor-shows-tlc-nand-based-ssds-at-cebit/" target="_blank">Last week</a> 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 Shows TLC NAND-Based SSD’s at CeBIT

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.
