Cheap NVME SSD’s with just a Chip, NAND flash

0


In many of the middle-class computers, where it is a very good price-performance ratio, it is still a hard drive, such as a coffin, in addition to the SSD as the primary system drive. Each motherboard has an M. 2 interface, so it almost does not matter, is compact, and can be used without any restrictions. The M. 2 2280 is also like an SSD, SATA SSD, but the models here are rare, and the 2.5-inch disks that are to be used. Under the PCI-Express 3.0 Ssd products, has formed a favourable niche, you have different models in play. Here, but it should be taken into account, not only on the maximum transfer rates, there are approximately three categories of methods:

In the first, inexpensive NVME SSDs have been such, that it is limited to two Lanes, PCI Express 3.0, which is the raw data rate in a two-rather than four-gigabit-per-second. Even if the work is reduced to one-half the rate of the transfer), the practice of performance, it is not necessarily so. Other models of push-up the price in favour QLC, which stores a four-Bit-per-cell, such as a Crucial to the P1, or-Intel-660p. You’ll love it here, but the speeds are acceptable, in need of such models to the SLC Cache. This is the full price of the performance level of your hard drive. This could be an opportunity for the users, it doesn’t matter who you bow to, but often higher value, with the Ssd without joy.

The third category of budget hotels NVME Ssd’s to store in the DRAM Cache. It also includes the WD Blue SN550 from Western Digital belongs to. As for the Ssd, with the QLC Flash, you are connected with four PCI-Express 3.0 Lanes, at the maximum, the width of the band, but a lot of times, as it is the most expensive, High-End SSDs (like WD Black SN750, Samsung 970 Evo Plus, etc.). The lack of a DRAM Cache is that the performance is outstanding, he protects you, but it’s the Flash of something in the Read and write accesses, so that it will remain for a longer shelf life. To the extent, but only in theory, because the package does not claim that the model of a DRAM Cache tend to die a natural death, you may do so.

WD Blue SN550 updated with the current BiCS4-Flash 96-the local

There was already a precedent, SN500, is still equipped with the old BiCS3-in Flash with up to 64 layers. The Driver was also a bit slower than the new house on the SN550: 2.400 MB/s read and 1,750 MB/s write with a capacity of 500 gigabyte (GB) instead of only 1,700 MB/s, and 1,450 MB/s SN500, which is limited to two PCI-Express Lanes. A large NAND chip is on the circuit Board, so that the labels between the Flash and the Controller is glued directly to the PCB rather than the Chips, as usual. In addition to this, the capacity is now up to a Terabyte bigger.

WD Blue SN550: Solid, middle-class-performance

First of all, it is possible to confirm the good reading performance of more than 2,400 MB/s, which exceeds the SN550 in our test, the Atto Disk Benchmark on it, not one little bit. Also interesting is that the write performance of approximately 1.740 MB/s in Atto, as well as on the SSD. The latter is used to unkomprimierbare of data that arise in practice, such as a Jpeg or to files that have been compressed with the most frequency, and the Controller is a little bit more abuse. Therefore, the rate of the data, AS the SSD is slightly lower than the previous Atto Disk Benchmark, pregnant with the most of the marketing For the out-of-tickling.

The direct competitors are the other cheap SSDs without Cache, DRAM, PCI-E 3.0, and four-lane expressways, such as the new Kioxia (Toshiba) RC500. They both use the same BiCS4 a Flash, the two companies have terminated the Joint Venture agreement. The two models use each and every one in the house, and the other Driver. Therefore, in practice), the performance is a little bit different from each other. Here, it is noted that the Kioxia RC500 is done a little better than the WD Blue SN550. In the test of copying a relatively small number of 10 gbps, but it is made up of more than 50,000 files, with the difference that it is for the upper-class SSDs is not that large. Only if you duplicate the entire folder of the game, in this case, the 120-to Give, they are fast models, like the WD Black SN750, a Kingston, KC200, or Figure out some other Firecuda 520 is significantly faster.

WD Blue SN550 the bottom line: a Fast NVME Alternative for the casual user

In the final analysis, the price is the most important factor in this market segment, and if a SSD is worth it. On the one hand, and the difference to the higher class, such as the WD Black, SN750, not great, on the other hand, the current street price of around 90 Euros, and the Kioxia RC500, which is a touch better. This is not to say that it’s the WD Blue SN550 is meaningless, in the sense of the model of the SSD-prices change daily and with the highest availability and the lowest-price model, the price would be the performance of the firecracker changes. The lack of a DRAM Cache is not at a great disadvantage to those who do not claim a unit of frequency. This is the case, for example, it is not constantly in the gaming facility, to amend, or constantly, in the Videos that are provided. Just because you move to the upper-class is not that great, we recommend it, but it is something more than an SSD with DRAM Cache. Good role models are on a WD Black SN750, a Corsair, MP510, or a Samsung SSD, 970 Ego-Plus.

Hard drives are now down to just a few PCs as the primary means of storage is in use. Even as a mass storage, and the SSDs are getting more and more into the ascendant. What is the card to which the scene is the best, and that is the PCI-Express and SATA models, we have to bring our purchases to the board, we will be presenting different models from different manufacturers, in various price classes.
