Intel has already presented a fresh series of SSD for the cloud - series DC S3700, which was announced at the end of last year. A new series - DC S3500 - presented yesterday and is intended to support older series in the lower performance segment. In general characteristics of the models DC S3500 resemble to the specification of SSD Series DC S3700. But there are important differences.
For example, the speed of reading random 4KB up to 75,000 IOPS, the write speed of arbitrary blocks in the junior series is three times lower. For the 800-GB model S3700 this parameter is 36000 IOPS, and for 800-GB model S3500 - 11,500 IOPS. But the price of Series storage S3500 half the cost of similar capacity models S3700. The same 800-GB SSD S3700 in wholesale lots worth (worth in the first quarter), $ 1,880, and 800 GB SSD S3500 priced $ 979. Note durability of S3500 Series storage is also reduced due to the use of less resistant memory. The older series was based on flash chips HET NAND MLC, and the youngest - the usual 20-nm NAND MLC.
As for read and write speeds, they both are equal. For older models performance numbers are 500/450 MB / s. The younger series begins with 80 GB capacity, which will cost in the party from 1000 pieces $ 115 each. Interface - SATA 6 Gb / s. The controller S3500, the same as in the Series storage S3700 - Intel development . Related Products :
