These were second hand disks that we purchased to replace failed units (they worked), as such this review will concentrate on these disks versus the SSD alternatives in a server environment. First up, there have been long term read/write problems of reliability with SSD technology, and given their expense this is not at all good. The SSD's are slightly faster however (maybe 7%) but once you have them in a RAID 10 or 60 they show little benefit as the bigger bottleneck will probably be your network! The best way to fix this is to go 10Gbe of course but this means new cards on your servers, new switches and a host of further expenditure to go nowhere really fast(er). In summary therefore, and at this point in time (April 2017), we feel that a RAID built on a series of second hand 15K disks costing around £130 each for 600Gb. is a better price/performance solution than paying out for SSD's, however if the reliabity of the latter can be improved and the price comes down, that situation would change not least as the SSD's use significantly less power and as this is charged for by any Data Centre may tip the balance in their favour eventually.Vollständige Rezension lesen

I purchased a ST3600057SS and was astonished at its performance. When I say performance, I am basing it output from seeker v2.0, hdparm -t, and my subjective impression from using the computer. The seeker program reveals all of the 15K rpm SAS drives to have 3 - 5 ms average access time, which is to be expected for a 15K rpm SAS drive. The Fujitsu 300GB drives averaged 136 MB/s, the Seagate 450GB drive averages 166 MB/s, and the ST3600057SS averages 201 MB/s. To put the ST3600057SS' performance in perspective, my 64GB SSD Mushkin MKNSSDCL averages 235 MB/s.
Серверный диск по адекватной цене. Берем уже второй (этот не проверяли), но с предыдущим все ок.
