Đánh giá ssd wd green 120gb
We tested another entry SSD, the WD Green 120 GiB SSD Đánh Giá from Western Digital. Let’s seek how does it perkhung against its competitors. Check it out!Recently, we tested three new-generation entry SSDs: the Corsair Force LE, the Kingston SSDNow UV400, and the SanDisk SSD Plus, which are some of the most inexpensive sầu SSDs available today. Now we are including a new inexpensive sầu SSD: the WD Green.Before proceeding, we highly suggest that you read our “Anatomy of SSD Units” tutorial, which provides all the background information you need to know about SSDs.Just lượt thích the Kingston UV400 & the Force LE, the WD Green SSD uses TLC (triple màn chơi cell) memories. This kind of memory stores not two, as on most MLC memory chips, but three bits instead. It allows a higher data density và, thus, a smaller manufacturing cost for a same capathành phố chip.The issues with TLC memory chips, compared to lớn the two-bit MLC chips (and even more compared to lớn the SLC memory chip, that store only one bit per cell) are the smaller tốc độ (due lớn the error correcting mechanism) và a shorter lifespan, because there is more cell wearing on the erasing process (executed before writing new data).The TBW (total bytes written, which means the amount of data written on the drive before it begin khổng lồ experience tearing problems) for this Model is 40 TiB . Obviously, this is a very high number & must not worry home users, but it makes this Mã Sản Phẩm inadvisable for applications that need a big amount of data writing, like servers, for example.In the table below, we compared the tested units. All of them use SATA-600 interface & the 2.5” khung factor, with 7 milimet height.No products found.

Figure 1 shows the box of the WD Gren 1trăng tròn GiB.
On Figure 2, we see the WD Gren 1đôi mươi GiB, which has a plastic casing.
On the bottom of the drive, there is a sticker with unit info, as seen in Figure 3.
Removing the cover of the WD Green, we see the PCB. At the solder side, there are two flash memory chips.
At the component side, we see two flash memory chips & the controller chip. There is no cabít memory.
The controller used by the WD Green 120 GiB is the Silibé Motion SM2258XT, presented in Figure 6.
The flash memory chips are from SanDisk, and unfortunately we couldn’t find the official chip specs.
During our testing procedures, we used the configuration listed below. The only variable component between each benchmarking session was the SSD being tested.

Error Margin We adopted a 3% error margin in our tests, meaning performance differences of less than 3% cannot be considered meaningful. Therefore, when the performance difference between two products is less than 3%, we consider them lớn have similar performance.As you will have gathered from the previous page, we measured the performance of each drive using CrystalDiskMark.It is important khổng lồ note that we connected the SSDs to lớn a SATA-600 port on our motherboard rather than a SATA-300 port, which could cause performance limitations.First, we phối CrystalDiskMark lớn “All 0x00 Fill mode” to lớn evaluate the performance of the SSD when dealing with compressible data.
On the random read thử nghiệm with 512 kiB blocks, the WD Green was 23% slower than Corsair Force LE, 7% faster than the Kingston UV400, & 21% faster than the SanDisk SSD Plus.
On the random write demo with 512 kiB blocks, the WD Green was 20% faster than Corsair Force LE, 52% faster than the Kingston UV400, and 45% faster than the SanDisk SSD Plus.
On the random read benchmark with 4 kiB blocks, the WD Green was 74% slower than Corsair Force LE, 27% slower than the Kingston UV400, và performed similarly khổng lồ the SanDisk SSD Plus.
On the random write benchmark with 4 kiB blocks, the WD Green was 5% slower than Corsair Force LE, & 9% slower than the Kingston UV400 and the SanDisk SSD Plus.
On the random read benchmark with 4 kiB blocks và queue depth of 32, the WD Green was 39% slower than Corsair Force LE, 40% slower than the Kingston UV400, & performed similarly lớn the SanDisk SSD Plus.
On the random write benchmark with 4 kiB blocks & queue depth of 32, the WD Green was 11% faster than Corsair Force LE, 24% faster than the Kingston UV400, performing similarly khổng lồ the SanDisk SSD Plus.For this demo, we phối CrystalDiskMark khổng lồ the mặc định mode, which uses incompressible data.
On the sequential read benchmark, all the SSDs has similar performance.
On the sequential write benchmark, the WD Green was 16% slower than Corsair Force LE, 9% faster than the Kingston UV400, and 92% faster than the SanDisk SSD Plus.
On the random read chạy thử with 512 kiB blocks, the WD Green was 9% slower than Corsair Force LE, performed similarly to lớn the Kingston UV400, and was 24% faster than the SanDisk SSD Plus.
On the random write benchmark with 512 kiB blocks, the WD Green was 21% faster than Corsair Force LE, 52% faster than the Kingston UV400, & 45% faster than the SanDisk SSD Plus.
On the random read benchmark with 4 kiB blocks, the WD Green was 35% slower than Corsair Force LE, 32% slower than the Kingston UV400, and performed similarly to lớn the SanDisk SSD Plus.
And on the random write benchmark with 4 kiB blocks, the WD Green was 12% slower than Corsair Force LE, 9% slower than the Kingston UV400, & 11% slower than the SanDisk SSD Plus.
On the random read benchmark with 4 kiB blocks and queue depth of 32, the WD Green was 40% slower than Corsair Force LE, 41% slower than the Kingston UV400, và 19% faster than the SanDisk SSD Plus.
On the random write benchmark with 4 kiB blocks and queue depth of 32, the WD Green was on a technical tie with the Corsair Force LE và the SanDisk SSD Plus, but was 17% faster than the Kingston UV400.Analyzing the data obtained on our tests, the first conclusion is that the WD Green 1trăng tròn GiB maintains the same performance with compressible và uncompressible data on reading and writing operations, which is great.Compared to its competitors, we see that it was similar on some tests, slower in other ones, and faster on some of them. Our experience tells us this difference is not sensible in everyday usage.So, we conclude that the WD Green 1đôi mươi GiB is a good choice for the trang chính user looking for an inexpensive SSD khổng lồ work as the boot drive sầu on a desktop or máy tính xách tay PC.No products found.
