![]() ![]() Let’s begin with the new ADATA XPG SX8000.ĪDATA is no stranger to the SSD scene. We have the previously reviewed OCZ RD400 and Samsung SSD 960 Pro, and they will be joined by the new ADATA XPG SX8000 and the Plextor M8Pe. As a result, this shootout will be a much more keenly contested affair. Today, all of the major SSDs brands have realized the importance of supporting the PCIe 3.0 x4 interface and have released products that support it. Things have changed in the past couple of months. In fact, only two of them did, the other two were using slower PCIe 2.0 interfaces, and their performance weren’t competitive at all. That’s six times the bandwidth of SATA 6Gbps.īut in our last shootout, you’ll see that not all SSD manufacturers have drives that support this ultra-fast interface. This standard offers up to 984MB/s of bandwidth per lane, so with four lanes, you are looking at close to 4GB/s of bandwidth. The fastest SSDs today use the PCIe interface, specifically PCIe 3.0 x4. SATA-based SSDs are no doubt many times faster than your traditional spinning hard disk drives, but they are limited by the SATA 6Gbps interface. However, as we explained in our PCIe SSD shootout earlier this year. But now, they are so affordable and ubiquitous that is almost unthinkable for anyone to still be chugging along on a system that uses mechanical hard drives. They used to be extremely expensive playthings for hardcore enthusiasts. Plextor's PlexCompressor utilizes custom smart compression technology that gives you more storage capacity without impacting your experience or system performance.Note: This article was first published on 15th November 2016. SSD capacity is always a key point of consideration. Even if you are using a computer with others, you can still hide your private data safely and securely on the computer inside the PlexVault if you have a Plextor SSD. Plextor designed its PlexVault software to provide a secure storage space that gives you complete control of access privileges. Most of the software only works with the company's SATA products and not the PCIe and NVMe models. Plextor has a robust software package that includes many unique features. That's more endurance than the MX500 and Blue 3D, but it comes up short compared to the 860 EVO and its five-year warranty. The M8V carries a three-year warranty with 70 TBW of endurance for every 128GB of flash. We would call this position optimistic at best, but there are other factors to consider. The 256GB M8V falls in the middle, but the 512GB model we're testing matches the 860 EVO at $150. Crucial and WD/SanDisk have products at low price points and the latest Samsung SATA SSD sets the cap for a reasonably priced product. Plextor kept the 128GB class and omitted a 1TB drive. Most companies opt to skip the 128GB class this round, and instead focus on introducing new larger models. The Plextor M8V comes to market at $64, $90, and $150. Intel and Crucial/Micron use SMI controllers for a handful of SSDs so most of the development work, it seems, is dedicated to IMFT 3D flash. It's rare to see an SMI controller paired with Toshiba flash. The M8V wields Toshiba's BiCS3 flash in conjunction with the SM2258 controller. The SM2258 is a four-channel controller that supports up to 2TB of NAND capacity and 2GB of DRAM. The controller is a commodity part designed to deliver entry-level to mainstream performance at a low price point. The SM2258 controller has special features as well, such as low-density parity check (LDPC) error correction, but you can also find that on nearly every new SSD. Yes, Plextor offers features such as PlexNytro, but that's just a marketing term for the SLC cache that comes with every modern SSD. We've reached a point where there is very little innovation with new SATA SSDs. Random read/write performance tops out at 82,000/81,000 IOPS for the 512GB model, but both metrics decline with the smaller models. The random performance is lower than we normally see with tier 2 products. As the table shows, write speeds decline with the smaller models. The M8V offers up to 560/520 MB/s of sequential read/write throughput with the largest model. ![]() Plextor consumes a lot of Toshiba flash, so it doesn't surprise us that it is one of the first third-party companies manufacturing products with the new 64-layer 3D NAND. Plextor uses the SMI SM2258 controller, which is the same controller Micron uses in the Crucial MX500 and other recently released products. ![]() ![]() Other than the obvious form factor changes, the two products are functionally identical. ![]()
