Samsung Unveils New 870 Evo Ssd With Faster Performance
The Adata XPG SX8200 Pro, the SK Hynix Gold P31, and the Samsung 970 Evo Plus all represent, to varying degrees, a step up in speed from the SN550, though they differ somewhat in the features they offer. The SX8200 Pro is a good all-rounder, gigabyte gtx 1060 3gb with impressive performance and a useful software package. The Gold P31 is made by a lesser-known manufacturer and comes with barebones software but has great power efficiency that makes it a better choice for a laptop.
The Samsung MJX controller used here is new and reportedly improves host communication performance and improves compatibility with Linux, though it is the same controller found on the Pro model. The LPDDR4 cache will vary gtx 1090 in size depending on the capacity, but will max out at 4GB. Samsung has finally introduced a 980 SSD that isn’t part of the high-priced Pro line, and it’s mostly good news for performance-minded PC users — with a caveat.
The SATADIMM from Viking Technology uses an empty DDR3 DIMM slot on the motherboard to provide power to the SSD with a separate SATA connector to provide the data connection back to the computer. The result is an easy-to-install SSD with a capacity equal to drives that typically take a full 2.5-inch drive bay. At least one manufacturer, Innodisk, has produced a drive that sits directly on the SATA connector on the motherboard without any need for a power cable. Some SSDs are based on the PCIe form factor and connect both the data interface and power through the PCIe connector to the host. These drives can use either direct PCIe flash controllers or a PCIe-to-SATA bridge device which then connects to SATA flash controllers. In 2019, Gigabyte Technology demonstrated an 8 TB 16-lane PCIe 4.0 SSD with 15.0 GB/s sequential read and 15.2 GB/s sequential write speeds at Computex 2019.
The best less-expensive options, such as the SN550, do other things to mitigate that.3 But as a rule, SSDs with built-in RAM still tend to outperform SSDs without it. These upgrade picks all include their own RAM, which helps to improve their performance across the board when you’re working with large files or reading and writing lots of files at once. Western Digital’s WD Blue SN550 is an NVMe SSD that’s three to four times faster than the best SATA drives, even though the drives usually cost the same amount. This makes it a great, affordable option whether you’re building a new computer or upgrading the storage in one that’s two or three years old.
※ Since M.2 is a form factor specification, SSD manufacturers can produce various types of M.2 SSD with different interface (SATA-based M.2, PCIe-based M.2 and NVMe-based M.2, for example). With the SSD 970 EVO Plus, Samsung set out to address the disparity between sequential reads and writes. The new drive uses an improved version of Samsung’s memory cell technology, called V-NAND. Back up or restore SSD data to another storage device, then fix the corrupted SSD by formatting, especially when the SSD is write-protected due to file system corruption. When the SSD is a data disk, you can fix it directly after formatting and wiping.
Enterprise flash devices are designed to handle the demands of tier-1 application with performance and response times similar to less-expensive SSDs. The benefit of using a current HDD form factor would be to take advantage of the extensive infrastructure already in place to mount and connect the drives to the host system. These traditional form factors are known by the size of the rotating media (i.e., 5.25-inch, 3.5-inch, 2.5-inch or 1.8-inch) and not the dimensions of the drive casing.
SSDs can use traditional HDD interfaces and form factors, or newer interfaces and form factors that exploit specific advantages of the flash memory in SSDs. Traditional interfaces (e.g. SATA and SAS) and standard HDD form factors allow such SSDs to be used as drop-in replacements for HDDs in computers and other devices. Newer form factors such as mSATA, M.2, U.2, NF1, XFMEXPRESS and EDSFF and higher speed interfaces such as NVM Express over PCI Express can further increase performance over HDD performance.
