How long should a copy of 1500 GB take? The test show differently however.For starters, Sandra says it's only a 5,400RPM, and the read write tests for both Sandra and CrystalDisk only average out at about 100 MB/s. share|improve this answer edited Jun 9 '14 at 15:27 Peter Mortensen 7,277135281 answered Sep 28 '09 at 10:07 NightCoder 22114 add a comment| Your Answer draft saved draft discarded Sign Less is better, so the best performer is at the bottom (those boneheads). http://vgvinc.com/hard-disk/hard-drive-problem-moving-hard-drive-from-amd-system-to-pentium-system.php
Further, since a given amount of data, (let's use an example of 100 GB), can all fit on the outermost tracks and cylinders of a 7200 RPM 3T drive, compared to High end SCSI drives and the like can go up to 15,000 RPM.

I know there are too many small files so transfer speed would be slower than standart benchmarks but why he and i have too big difference? Read Access Time This tells you how responsive the drive is, how quickly it responds to a sudden small request. Average Read Throughput This chart will tell you how fast it should make medium to large copies. The full-speed rate of 12 Mbit/s (~1.43 MB/s) is the basic USB data rate defined by USB 1.1.

Seek time is simply the time it takes to start reading or writing a particular sector of disk - these can range from 3-15ms for disks to a small fraction of Hard Disk Write Speed FusionIO can easily hit 1GBps for all, but are typically small and expensive. If you're copying between two separate servers there are even more factors involved.
Creating a file can take several seeks, so making a 1KB file can "cost" as much as streaming several MB of data. roots of higher derivatives of exponential Color of fried beef steak: sometimes dark, sometimes light-colored.

I believe this is what best gives the impression of hard drive speed. share|improve this answer answered Jan 3 at 14:46 Zander 111 1 See this link and links from it for more details, help.ubuntu.com/community/Installation/… –sudodus Jan 3 at 15:06 add a comment| What is Intel RST? weblink RAID controllers with built-in cache can help with the seeks, as can something like the flashcache kernel module that lets you cache a block device via an SSD.
Finally, there is the drive itself. Then we get to actual speed you can expect, there are four speeds you should care about; sequential read (reading a very large block of data), sequential write (same but writing), Also, you'll see disk cache sizes, typically a larger cache means it can take better advantage of temporal locality. I ran the test multiple times with 2 different files sizes. 1GB gave me 50MB/s while 5GB dropped that to around 47GB/s. –Peter M May 7 '16 at 20:45 | show

For a professional server, faster drives mean faster performance under disk I/O load. Also FAT32 has a 4GB file size limit, NTFS is 16TB or more. Another sign of poor power is drive stalling during startup. Not the answer you're looking for?
