Ei pidä antaa tuon markkinoidun nopeuden hämätä.
Näkisin että A2000 on parempi valinta, vaikka onkin vähän kalliimpi ollen hyvä kompromissi hinnan ja suorituskyvyn osalta.
SSD / Kingston Technology A2000, 1000 GB, M.2, 2200 MB/s

Jos vähän parempaa haluaa, niin hieman kalliimmalla suosittelisin KC2500
Valikoimasta löytyy perinteisiä kiintolevyjä sekä uudemmalla tekniikalla olevia SSD-levyjä. SSD-asemat ovat nopeampia verrattuna perinteisiin HDD-levyihin.

Tom's hardware:
Like the Blue SN500, the SN570 features a tiny, static SLC cache. It absorbed roughly 12-13GB of data at 3.2 GBps before performance degraded. Once the cache was saturated, write speeds averaged 615 MBps for the remainder of the test. Thanks to the SN570’s small cache capacity, it recovers nearly immediately during each idle round.
KC2500 (TPU)
Write speeds start out at over 2.5 GB/s, which is very impressive. The drive sustains these write rates until 150 GB have been written. At this point, the SLC cache is full, and the drive will start flushing SLC back to TLC, which has an effect on write rates. With 1.4 GB/s in that state, speeds are still very high, much better than most other TLC drives on the market. When over 600 GB of data have been written, speeds drop a little bit further, to 700 MB/s. When write activity stops and the SLC cache has had time to free up some capacity, full write rates will be restored even if the drive is partially filled
The Kingston KC2500 promises to offer higher transfer rates than the Kingston KC2000, which it is based on. Due to a new firmware, Kingston was able to unlock additional performance. We measured almost 3 GB/s in writes and well above that in reads.

A2000 (TPU)
Write speeds start out at an impressive 2 GB/s. The drive sustains these write rates until around 150 GB have been written. At this point, the SLC cache is full, and the drive will start flushing SLC back to TLC, which has an effect on write rates. With 500 MB/s in that state, speeds are still reasonably high—matching the best SATA drives. Once over 600 GB have been written without pause, rates drop a little bit further, to 400 MB/s. The average of 480 MB/s is better than most other value-oriented TLC drives on the market. Once the SLC cache has been flushed completely, write rates jump back up to full speed—this process repeats for the whole duration of our test
