DAS Promise Pegasus R4 Review

Data storage units have become an integral part of PC hardware in recent years. Such conjuncture is simply explained by the rising necessity to store huge amounts of information and transfer the data to various devices. NAS and DAS units have been developed with the intention to solve all storage problems, however, the efficiency of their work is much dependent on the interfaces they use for data transfer. USB 2.0 interfaces are unable to cope with voluminous info; the prevalent now USB 3.0 and eSATA interfaces are efficient only for a single winchester. But when it comes to the management of really huge data blocks, there appears a need for a more advanced solution. Promise Technology dares to solve all vital issues by releasing DAS Pegasus R4 with Thunderbolt interface which is notable for the high and stable data transfer speed with the retention of compatibility.

GeIL Officially Introduces Zenith S3 SSD Series

GeIL, which is known for its high-end memory modules, drives, and other PC components, is going to release a new SSD series, codenamed Zenith S3. The series will embrace three models of 60GB, 120GB and 240GB capacity. All of them will be developed in 2.5-inch form-factor and will employ SATA III 6Gb/sec interface. The differentiation between the models is seen not only in their capacities but also in their speed performance, the index of which will be uncovered below.



Zenith S3 line is based on MLC NAND flash-chips designed under 25 nm technological process. As for the speed characteristics, all models in the series prove to demonstrate the maximal performance on random Write operations (4KB) – up to 70000 IOPS. When touching upon sequential speeds, each model shows different indeces:

— GZ25S2L-60G: maximal sequential Read speed – 500MB/sec, maximal sequential Write speed – 480MB/sec (recommended price — $70);

— GZ25S3L-120G: maximal sequential Read speed – …
