(not to be confused with the two sets of NAND chips for the internal storage of new MacBook pro's and Mac studios, which are controlled by a single chip and NOT raid. And for reasons it doesn't suffer the same issues as running a software raid on a Mac. My old (not really that old) Glyph M2R 4TB thunderbolt SSB *is* internally running raid 0. And once you see those numbers, you might end up diving into deep rabbit holes.Īnd yes - Raid 0 is generally not great for sample libraries. Oh - and even good ol activity monitor is good for seeing real-time what a drive is doing. SSDs are fine.ĪTTO make an awesome drive benchmarking tool - which can sequentially test different size read/writes and display on a graph. you don't really need NVMe M.2 drives for audio. don't worry about filling up your drives Note that the random 4k performance is still pretty good at 205MB/s - still 3x faster than 4 M.2 drives in a RAID0! And actually they're still pretty fast even though the drive is almost full!Īnd just for comparison, here's an old Samsung 860 EVO SSD in a BlackMagic Multidock. The above drive is 97% full but notice how only the WRITE speeds are affected. READ speed is still extremely fast even on a full drive. ![]() How do those results vary on a full drive? We often hear about needing to leave 10-20% free on SSDs to preserve their speed, but this only affects WRITE speed. Still great contiguous read speed at 6.7GB/s but look at the random 4k result - 649MB/s - 10x faster than the RAID0! Wow! 13.8GB/s read speed! Great for video, but look at the random 4k result - only 64.47MB/s! RAID0 just isn't a good choice for sample libraries. These will test the all-important random 4k read speeds which matter for library streaming. The BlackMagic disk benchmark only measures reading and writing of large contiguous files and isn't much use for audio tests. They are mainly of interest to people doing video work, where you work with very large contiguous files with extremely high data rates.Īudio streaming is all about loading (tens of) thousands of tiny audio files in a fairly random order. Your contributions will be deeply appreciated.The high figures (500MB/s, 3.5GB/s, 7GB/s etc) advertised by SSD/NVMe manufacturers aren't actually that relevant to audio work. Please make the amount of each contribution $10 USD or more (in JPYen, 1000Yen or more) if possible. If you want to contribute to supporting the continuance of this project, please make donations by Paypal. As to current status, this project is extremely short of funds and is in desperate need of your donations. ![]() Therefore, this project needs more development funds. ![]() Any software development demands huge amount of time and effort, and on top of that, new hardware devices are released one after another which becomes a necessity to purchase in order to support them. ![]() information such as how many times the power was turned on, the time length of use, and temperature to monitor the state of the disk.īoth CrystalDiskInfo and CrystalDiskMark are open source software personally developed by me. In addition to information like model number, volume, buffer size, it obtains S.M.A.R.T. If anything abnormal is detected, it will notify you by text or voice message, and it supports both HDD and SSD. CrystalDisklnfo is disk utility that supports some types of USB connections, Intel RAID, and NVMe.
