The big thing Samsung want to push with the EVO is the increased write speed for the low capacity models. Using a new feature called 'TurboWrite' (more info on this as we get it), compared to the previous 840, whereby the 120 GB model was rated at 130 MB/s and 86K/32K 4K random IOPS, the new 120 GB model is hitting a rated 410 MB/s write speeds.&nbsp; The peak 1 TB model is rated for 540/520 MB/s sequential read and write, with 98K/90K IOPS respectively.&nbsp; The 1 TB models will also feature 1 GB of LPDDR2 DRAM Cache.</p>

Enterprise storage is also the focus of the SSD Summit, with Samsung unveiling the XS1715, an ultra-fast NVMe (Non-Volitile Memory Express) SSD with up to 1.6 TB of storage.&nbsp; The XS1715 is the first 2.5&rdquo; SFF-8639 SSD using PCIe 3.0 to provide a maximum sequential speed of 3 GB/s, along with 740k IOPS.&nbsp; The XS1715 will be available in 400GB, 800GB and 1.6 TB versions, with plans to develop the line of NVMe devices.</p>

More information from the Summit as it occurs throughout today and tomorrow!</p>

Thus for the 1TB model, $650 makes the drive $0.65/GB. &nbsp;At the 250GB price point, the basic Evo package is $190, compared to the current 840 standard price of $175 at Newegg.</p>
