[1.665 lb] I am happy to see that B&H is still #1 in quality, pricing and delivery. Thanks kindly for such careful packaging. Your team is consistently great!

[4 TB] Arrived on time. Installed without a problem and is working wonderful!

[1.665 lb] I already had one of these drives that I purchased earlier this year for my NAS, when an older WD drive recently conked out I immediately purchased another one of these. Drive is quiet and works like a champ, no issues.

[1.665 lb] Pricey, but didn't want any issues with Synology. Long term the cost won't matter. I am a home use that utilizes the system (DS1621XS+) for photo management and workflow, surveillance, and backup not only of home system but remote work site. Attached via a 10gbe backbone with speeds greater than 600 MB/s. Couldn't be more thrilled. Purchased along with synology 12 TB hard drives (qty 6), 32GB ram, and 2 400GB NVME drives.

[4 TB] Purchased two for new DS214+ Synology NAS unit - Work GREAT! Super easy install in synology NAS unit. You DO have to say, YES it's I know these are not the recommended Synology (Toshiba) Drives that Synology recommends..... But, nonetheless, they work without any issues I can determine. Installed as a Mirror RAID1 system. Ends up 7.3TB usable space... plenty fast, quiet, suits intended purpose. Would definitely recommend to others for Use in dual drive NAS unit!

[1.665 lb] Almost all Raid arrays are limited to multiples of the capacity of the smallest disk drive in the group. This was an economical way to get my array up to 4T disks to eliminate that semi-hidden (if you fail to read the fine print) reduction in overall, array capacity. The second limit on RAID arrays is the cache size/speed. With 3 of these 4T disks I was able to switch out my older 2T 64MB cache drives for a new cache size of 256MB which means a bigger chunk of data can be written to the drive significantly increasing in effective disk/array speed.

[1.665 lb] These drives are a significant improvement over two competitive drives with the caveat that we have no experience with longevity as the drives have only been running 10 days. We replaced two drives in a four bay NAS from another manufacturer as the first two failed at 55,000 and 58,000 hours. So much for MTBF of 1 million hours. The other two that were replaced were new drives from a different manufacturer, but they were very noisy. The Toshiba drives are far superior from a noise perspective. They are difficult to hear a few feet away. I/O seems very good as well. Hope these last many hours. Ordering and shipping from B&H was quick and easy as normal.

[1.665 lb] Works well as an entry level NAS Drive.

[4 TB] Excellent drives Fast but not noisy at all

[1.665 lb] I have used Toshiba 12TB NAS300 HDDs in my Qnap TS451 & TS-453A NAS systems for 4 years running 365 days/year and 24 hours/day and none have failed.
