Half-baked ideas

By -
Recently, surfing the net I came across the site where people advance various ideas.
First I was interested in this:
The point is to create a SSD using USB thumb drives. We decided to calculate the economic aspect of this project. It was found that much easier and cheaper is to buy a ready-made SSD rather than try to create it with heaps of USB thumb drives.
With thumbdrives, you get the cheapest price per gigabyte if you use 7x 64GB USB thumb drives and one 7-port USB 3.0 hub (the cheapest hub at newegg). Thus, the price of such 448 GB storage is 79 cents per gigabyte while for 480 GB SSD the price is 67 cents per gigabyte.
Further I encountered this idea
The idea intends to combine old computers into network and to create iSCSI RAM disks. Looks really interesting save for one problem.
The problem is that an electric bill very quickly becomes more expensive than a SSD. Such system with capacity say of 500 GB will consume electricity at a rate of about $400/month. Again, in just one month this becomes more expensive than a ready-made SSD.

QNAP revisited

By Geek -
For reference, we were using QNAP TS-639 Pro with six WD20EADS disks. After about half a year of use, the web-interface was running slower, so that we needed to wait for several minutes to obtain the list of the disks. Gradually, we noted that the array performance decreased significantly. It seemed obvious to assume that one of the member disks has been dropped from the array and a RAID5 was working in the degraded mode. However, all the member disks were marked as GOOD in the web-interface. It was suspicious that LEDs on the disk bays indicating the state and activity of the disks were blinking unevenly. Logically, for RAID5 one should expect almost symmetric load on the disks, but in fact, one of the disk LED was blinking much more frequently. Once we had run the bad blocks check on this disk through the web-interface, the disk dropped from the array in less than half an hour and its bay LED turned red. At this point, the web-interface began to work properly again. The disk taken fr

APFS Data Recovery

By -
Apple File System, APFS for short, is a brand-new filesystem released in 2017. The goal is to replace HFS+ which has been in use on Apple computers since 1998. Formally released in late 2017, APFS filesystem began to be used by default on Apple computers running under MacOS High Sierra. Among the main features of APFS filesystem are 64-bit pointers allowing to address 2^56 blocks More accurate created/accesses/modification time measured in nanoseconds since 1970-01-01 Copy-on-write Sharing blocks between APFS volumes Native full-disk encryption We are happy to announce that now ReclaiMe data recovery software is capable of recovering data from APFS-formatted devices be it a USB thumb drive, or external hard drive, or internal SSD boot drive. You can download the latest build of ReclaiMe at www.ReclaiMe.com .
