What 4TB changes in a NAS plan
Its capacity is practical only if it leaves enough room for growth before the next drive replacement. Calculate formatted space, redundancy, snapshots and backup copies before deciding how many drives to buy.[1]

Plus Series 4TB: specifications and dated store comparison →4TB decimal for Synology home and small-office systems, with the exact HAT3300-4T revision kept separate.
One Synology Plus Series 4TB HAT3300-4T internal SATA hard drive. NAS enclosure and other drives sold separately.
HAT3300-4T is the 20.20 mm, 5400 rpm, 4 TB Plus disk. Hardwareluxx tested two Synology-supplied ST4000VN3300 samples. The 2026-09-11 Newegg page is not a qualified current offer: the H1 prints HAT3310-4T while the specification Model and ItemDetail Model print HAT3300-4T. B&H $229.99 remains the 2026-08-30 observation. ChooseCompute has not tested this drive. See the review evidence ↓

One drive provides 4TB decimal before formatting; redundancy and growth allowance still reduce practical headroom.[1]
The documented 180TB/year read, written or verified and family features support this intended class, within the exact host compatibility boundary.[1]
Published acoustic labels and review observations, when available, do not predict resonance or seek noise in your enclosure.[2]
The evidence does not establish performance for every array, network, database or virtual-machine workload.[2]
Follow any specification for its full conditions and sources.
Living with it
Its capacity is practical only if it leaves enough room for growth before the next drive replacement. Calculate formatted space, redundancy, snapshots and backup copies before deciding how many drives to buy.[1]
The rating is useful for checking the exact HAT3300-4T column. It does not guarantee a network transfer rate or random-I/O result, and it should not be copied to a neighboring MPN.[1]
Our buying advice combines official specifications with the original reviews below. We have not tested this product ourselves. Expand a review for its setup, measurements and limitations.

The retained Tech ARP review reports ATTO throughput close to the 202 MB/s specification, with peaks around 205 MB/s. Its full test settings and chart values could not be reverified from the currently inaccessible article. This is not a NAS-array or longevity test.

Updated Jun 30, 2025
Tested: One exact HAT3300-4T tested alongside 4TB and 6TB WD Red drives with CrystalDiskMark, ATTO, surface-temperature monitoring and power observations; complete host and benchmark settings were not visible on the opened pages.
Applies to: Exact drive performance and temperature comparison; not a NAS-array, endurance or failure-rate test.
| Measurement | Result | Conditions & source location |
|---|---|---|
| ATTO peak read / write | just under 205 / just over 205 MB/s | Single drive; chart-read values, full host settings not disclosedPage 4, ATTO chart |

Hardwareluxx tested two Synology-supplied HAT3300-4T samples. Spin-up was 23.92 W; idle after ten minutes was 1.90/2.07 W. Copy power was close at 3.52/3.56 W, but random-read power differed at 5.41/7.84 W. Single-drive CDM sequential results were about 200–214 MB/s, and two-drive RAID 0 reached about 399 MB/s. These are controller-bench results, not NAS-network speeds; idle noise used the site’s new 2023 protocol.
Read the original reviewSynology HAT3300 4TB review
Tested: Two HAT3300-4T samples supplied by Synology (printed ST4000VN3300; page 6 tables typo ST4000VN0033). Host: Core i9-12900KS, MSI MAG Z690 Tomahawk WiFi DDR5, Crucial 32 GB DDR5-5200 CL42, Windows 11 Pro (then-current 2023), Adaptec SmartRAID Ultra 3254-16e/e in an AIC J2012 SAS3 chassis. Bench also lists 4×1 TB Seagate BarraCuda Q5 RAID 0 as source SSDs and 2× Kioxia PM7-V 3.2 TB cache SSDs. Two-drive RAID 0 tests disabled controller cache. Power: Rigol DS1054Z, Rigol PVP 2150 probes, PicoTech TA189 clamps, 5 V and 12 V together, ~1 minute repeats.
Applies to: Exact 4 TB samples on a high-performance RAID controller. Single-drive numbers are not NAS-network throughput. RAID 0 figures are a two-disk controller array with cache off, not a Synology volume.
| Measurement | Result | Conditions & source location |
|---|---|---|
| Spin-up power, both samples | 23.92 W / 23.92 W | Rigol DS1054Z + PVP2150 + PicoTech TA189 on 5 V and 12 V together; ~1 minute, repeated. Page 3 Anlauf chart labels Toshiba S300 HDWT840 at 17.54 W; HAT3300-4T ST4000VN3300 is 23.92 W. Page 6 confirms both samples 23.92 W.Page 3 Messung 1; page 6 sample comparison Anlauf |
| Idle power after 10 minutes | 1.9 W sample 1 / 2.07 W sample 2 | Same dual-rail method; wait 10 minutes with no host commands. Page 3 idle chart labels Toshiba S300 at 1.81 W; HAT3300-4T is 1.9 W. Not the manufacturer 3.96 W typical idle.Page 3 Messung 2; page 6 Leerlauf |
| Copy power (50 GB Windows 1809 image, repeated) | 3.52 W sample 1 / 3.56 W sample 2 | Cache fills then media write; dual-rail average.Page 3 Messung 3; page 6 Kopieren |
| HD Tune Pro random-access-read power | 5.41 W sample 1 / 7.84 W sample 2 | Standardized RAR load. Author notes ~50% difference and that a third sample would be needed. Do not describe the two samples as uniformly close.Page 3 Messung 4; page 6 Random Access Read |
| CrystalDiskMark 8.0.4 x64 sequential (textual charts; test size/QD not stated) | Sample 1 200.06 / 196.37 MB/s read/write; sample 2 213.93 / 213.91 MB/s | Single-drive Adaptec bench, not a NAS share.Page 5 CDM charts; page 6 sample CDM |
| HD Tune sequential read max/avg/min | Sample 1 193.7 / 153.6 / 84.5 MB/s; sample 2 206.5 / 162.5 / 90.7 MB/s | Page 6 repeats the sequential-read table under the next heading, so sample 2 write values cannot be taken from that duplicate.Page 5 HD-Tune Lesen; page 6 duplicate Lesen table |
| HD Tune sequential write max/avg/min, sample 1 | 192.4 / 152.1 / 19.3 MB/s | Sample 1 shows a write dip to 19.3 MB/s min. Page 5 text says the second sample did not show that write dip; sample 2 write numbers are not on the duplicated page-6 chart.Page 5 HD-Tune Schreiben |
| Two-drive RAID 0, controller cache disabled | CDM 398.76 / 399.94 MB/s read/write; HD Tune read 357.8 / 288.1 / 162.2 and write 335.6 / 274.9 / 148.1 MB/s | High-performance RAID controller array, not a Synology NAS volume and not single-disk. RAID 0 has no redundancy.Page 6 RAID 0 charts |
| Idle sound level, new 2023 room protocol | 22.0 dBA sample 1 / 22.4 dBA sample 2 | Idle is the mean of readings a few seconds before and after RAR. New room/protocol is explicitly not comparable with older Hardwareluxx HDD noise tests. Microphone distance and background are not stated.Page 4 idle chart; page 6 idle comparison |
| RAR load sound, two HTML numbers per sample | Sample 1 26.3 and 24.5 dBA; sample 2 27.2 and 25.5 dBA | Prose says RAR average plus peak. The HTML class on the second number says min. Report both numbers; do not pick one as a ranked dBA.Page 4 Last chart; page 6 Last comparison |
Limits to keep in mind
Before you buy
Each current row keeps the selected main seller, condition, availability and only a price visible without a cart action. Null price means the main buy box hid it; every current fact is a dated observation that requires a fresh check before purchase.[6]
The 3 retained historical listings keep their original August or early-September 2026 dates and are not overwritten by the 2026-09-10 observations.[4][5]
Check HAT3300-4T, new condition, seller, regional warranty channel, shipping and return terms. A marketplace product page does not by itself identify the current seller.[6][4]
A mirrored or parity-protected layout may require multiple drives, while a separate backup needs additional storage. Compare total delivered cost for the complete plan.[1]
The Newegg H1 is “HAT3310-4T” while the spec table Model is HAT3300-4T (ItemDetail Model HAT3300-4T, Description Title still says HAT3310-4T). Visible price $219.99, sold-by Newegg. That capture is a pending candidate, not an exact-MPN current offer. B&H $229.99 on 2026-08-30 was not refreshed. Amazon 2026-09-10 still has no usable USD price.[8][4]
