How about Toshiba mobile hard drives How to distinguish the models of Toshiba hard drives?

Kawasaki Toshiba Electronic Storage*** recently launched the high-capacity 18TB N300 series hard drives, further improving storage capacity and energy efficiency to meet customers' growing storage needs. The N300 18TB is a 9-tray helium-sealed Traditional Magnetic Recording (CMR) disk that uses Toshiba's innovative Magnetic Energy-Controlled Microwave-Assisted Magnetic Recording (FC-MAMR) technology to operate around the clock to ensure consistent high performance, making it the first choice for home office and small business users.

SMR, also known as laminated magnetic recording, is a new technology that hard drive manufacturers are promoting. The biggest advantage of SMR technology is that it can significantly increase the storage capacity of the hard disk.

PMR is a perpendicular magnetic record that is essentially the same as CMR reliability.

Toshiba MD07ACA:7200 conversion, 12TB (MD07ACA14T) 14TB (MD07 ACA12T) are CMR or traditional magnetic recording technologies.

The Toshiba MD04ACA:7200 conversion, 2TB, 4TB, 5TB and 6TB versions all feature CMR technology (specific models include A200, A600, etc.).

The Toshiba DT02ACA: 5400 conversion, 4TB (DT02ABA400) and 6TB (DT02ABA600) versions are all versions of SMR stacked magnetic recording technology.

Toshiba DT01ACA: 7200 conversion, 500GB, 1TB, 2TB and 3TB versions all use CMR technology (specific models include A050, A300, etc.).

The Toshiba N300 18TB is rated for a working capacity of 180TB year. It supports up to eight bay NAS operation, open the box TOSHIBA N300 18TB. 7200 rpm with a data buffer of up to 512MB, ensuring high performance and fast read speeds in data-intensive operations; The specific model is HDWG51J, and Toshiba N300 series hard disks are divided into N300Pro and N300; The N300 18TB in this evaluation comes with a 3-year warranty with a rated workload of 180TB years and an MTTF of up to 1.2 million hours, the Toshiba N300 18TB box internal hard drive is wrapped in airbags for no need to worry about collisions during shipping, and inside, there is a quick installation guide and N300 18TB hard drive body.

Toshiba's unique on-board caching algorithm and buffer management optimize cache allocation between read and write cycles to improve real-time drive performance; The main control chip is 88i1215-BW12 produced by Marvell; There is an RV sensor on the PCB, and the free space for a single disk performance test on a Windows system is about 163TB, according to the information of CrystalDiskInfo, it can be seen that the Toshiba N300 18TB has a speed of 7200RPM, HD tuning test. Fast data transfer speeds of up to 282MB s provide fast access to essential content, which can remain above 118MB s even in the slowest position in the inner ring, Crystal Disk Mark default option test, with a read speed of about 292MB s and a write speed of about 284MB s, and Txbench test, with a read speed of about 289MB s and a write speed of about 293MB s.

Disk transfer rate detection

Write files to Toshiba N300 18TB at a write rate of about 279MB s, read files from Toshiba N300 18TB at a read rate of about 272MB S, perform performance tests on NAS using four N300 18TB group RAID cards, DS1821+ with Intel X710T2 10G network card, four RAID 0 use 10G LAN port to upload documents to NAS with a write speed of 107GB s, retrieving documents from NAS using a 10G LAN port with a read speed of 109GB s, ISCSIS storage installed.

Tested with CrystalDiskMark by default, iSCSI installed for storage, CrystalDiskMark tested under 4K random conditions, four-disk RAID 5 uses a 10G LAN port to upload documents to NAS, and the write speed is 102GB s, retrieving documents from NAS using a 10G LAN port with a read speed of 100GB S, ISCSIS storage installed, tested with CrystalDiskMark by default, Install iSCSI for storage, CrystalDiskMark tested under 4K random conditions, Noise and vibration test: remove the fan of DS1821+, turn off the alarm sound, ambient noise within 60 seconds, maximum noise level 348db, minimum noise level 346db with an average noise level of 347dB, 4 Toshiba N300 18TB idle for 60 seconds, maximum noise level 366db, minimum noise level 357dB with an average noise level of 360db。

Upload files to four Toshiba N300 18TB via a 10G LAN port for up to 60 seconds with a maximum noise level of 402db with a minimum noise level of 355db with an average noise level of 362db。The peak of the noise curve is the moment when the four Toshiba N300 18TB vib, which have a large capacity, high speed and long service life. It can support stable operation in NAS systems with up to 8 disk slots and maintain reliable performance, achieving optimal reliability and system scalability, enabling you to store and share valuable files with confidence. Whether you're a business user or a content creator, the Toshiba N300 18TB is a great choice.
