IRON FOR MAN IN THE ESSB RADIO!
For a long time to process signals on my machines I used SSD drives in 1 tr, and recently decided to check for bad sector, on one of the discs of their found 5 bad sectors.
After identifying this problem I decided to make a clone system on a normal Winchester. But since I really haven’t had id, SATAI and SATAII, I took advantage of a Seagate Cheetah 15K.7 600GB SAS 6Gb/s (ST3600057SS) at a bargain price of 8,000,000 hryvnias.
With Dell PERC H730 controller – Storage Controller (RAID) – SATA 6Gb/s / SAS 12Gb/s – PCIe 3.0×8 – 12Gb/s SAS, Serial ATA/600 – PCI Express 3.0 x8
Well, after the complete clone of the system on the SAS and the launch already on the new Winchester I heard a completely different quality of processing. I was even surprised by this phenomenon. To keep the experiment clean, I recorded the system on SSD and SAS, then compared the two records with an analyzer. It turned out that the signal on the SSD system is dry, plus additional system noise, on SAS the signal is juicy and spectral is pronounced and minus 2-4 Db noise system. In short, sAS Winchester is the best for sound processing. But it’s expensive. The controller costs $500 and the Winchester is $330, but you can still take a smaller drive and controller to SAS 3Gb/s and come out at $150.
But there is still the SCSI U320 system, it is the progenitor of the SAS system. I bought the Lviv controller and Winchester SCSI U320 – Adaptec 29320A Ultra320 SCSI U320 Card w/ HostRAID PCI-X, 133, 64 Bit and Winchester IBM 146Gb U320 SCSI HP 15K, and got the same result. The answer to the question what affects the quality? Many factors such as a separate data processor not including the CPU, cache and drive speed. 15k is the speed of the disk’s rotation.
Now the conclusion can not bother with SAS, you can just buy the system SCSI U320 and it will cost you $30
